Free RBT Practice Exam: 85 Questions, Built to the 2026 Blueprint

Correct: A. Rate is count divided by observation time in the unit the data sheet asks for: 18 ÷ 45 minutes = 0.4 responses per minute.

B inverts the division (45 ÷ 18). C reports the session total, not the requested rate per minute; session totals alone do not standardize observations of different lengths. D is a correct rate — 18 ÷ 0.75 hours = 24 per hour — but it answers a question that wasn't asked. Watch the unit in the request, not just the arithmetic.

Review takeaway: Rate is a count divided by time, in the unit the data sheet asks for.

Sources: IRIS: Behavior Assessment—Frequency and Interval Recording, pp. 1–2; operational definitions, rate formula, whole/partial interval rules; BACB RBT Test Content Outline (3rd ed.), A.6; calculation shown in the explanation.

Correct: B. Something was removed after the behavior (the worksheet), and the behavior increased. Removal plus an increase is negative reinforcement.

A would require adding something. C and D are both ruled out by the outcome: punishment means the behavior decreases, and whining went up. The "positive/negative" half of the label describes whether a stimulus was added or removed; the "reinforcement/punishment" half describes what happened to the behavior. Decide the second half first — it's the half people get backwards.

Review takeaway: Settle whether the behavior went up or down first — that half of the label decides reinforcement versus punishment.

Content area C · Behavior Acquisition · Task C.1 · Item RBT-C01

Sources: OpenStax Psychology 2e: Operant Conditioning, Reinforcement and punishment; Shaping; Primary and Secondary Reinforcers; Reinforcement Schedules.

Correct: C. The RBT Ethics Code (2.0) requires RBTs to protect client confidentiality and privacy under BACB, employer, and legal requirements (2.08), and to share client information only under the supervisor’s direction or where the law allows it for a valid reason (2.10). Past employment does not establish current authorization.

A still releases clinical information to an unauthorized recipient. B does not establish permission to release the record, and removing a name alone does not establish that a record is nonidentifying. D treats past access as a permanent entitlement. Route the request through the authorized process rather than deciding on disclosure yourself.

Review takeaway: Verify authorization before releasing client information. A familiar name is not authorization.

Content area F · Ethics · Task F.5 · Item RBT-F01

Sources: BACB RBT Ethics Code (2.0), §§2.08–2.10.

Correct: B. The behavior starts when a specific item is removed and stops when it is returned. That pattern supports an access-to-tangibles hypothesis; it does not establish the function by itself.

A is less supported because no demand was described. C is not established by these observations. D is possible because adults also respond, but the clearest described change is the item being removed and returned. Record that pattern for the supervisor; the fact that screaming stops when an item returns does not, by itself, prove what maintains it.

Review takeaway: Look for the consequence associated with the behavior, and distinguish a hypothesis from a demonstrated function.

Content area D · Behavior Reduction · Task D.1 · Item RBT-D01

Sources: EBIP: Challenging Behavior as Communication, ABC descriptions and hypothesis discussion; BACB RBT Test Content Outline (3rd ed.), D.1; B.3.

Correct: C. Partial-interval recording scores an interval the same whether the behavior happened once or ten times, so the only summary it supports is the percentage of intervals containing at least one occurrence — here, 15 of 30 intervals, or 50%.

A is information this interval sheet does not retain; the "several sounds" intervals are scored identically to the single-sound ones. B requires duration recording. D requires interresponse-time data. Do not read 50% of intervals as 50% of observation time: even a brief occurrence counts for a whole interval. With equal intervals, that substitution can overestimate the proportion of time occupied by the behavior.

Review takeaway: Partial-interval data give a percentage of intervals, not an exact count or percentage of time.

Content area A · Data Collection and Graphing · Task A.2 · Item RBT-A02

Sources: IRIS: Behavior Assessment—Frequency and Interval Recording, p. 2, partial-interval rule and percentage calculation.

Correct: B. Least-to-most starts with the least assistance — none — and adds progressively more intrusive prompts when a correct response does not occur, following the plan’s hierarchy.

A describes most-to-least. C and D both deliver a prompt before the independent opportunity required by this plan. Immediate prompting can be part of an error-minimizing procedure, but timing alone does not define a complete errorless-teaching plan. Neither is wrong as a procedure; both are wrong as an answer to "the plan says least-to-most." Run the hierarchy the plan specifies rather than the one you find easier.

Review takeaway: Least-to-most starts with no prompt. Run the hierarchy the plan names, not the one you prefer.

Content area C · Behavior Acquisition · Task C.7 · Item RBT-C02

Sources: EBIP: System of Least Prompts, Overview and prompting sequence.

Correct: C. It reports countable events anyone watching would score the same way.

A, B, and D report conclusions about the client's inner state or the cause of the behavior. "Defiant," "rough day," "frustrated," and "unmotivated" can't be observed, and B adds a cause the RBT did not witness. Sleep information can and should be documented — as something the caregiver reported, not as the reason for the session. Objective documentation is a requirement of the role, not a writing preference.

Review takeaway: Write what another observer could score the same way you did.

Content area E · Documentation and Reporting · Task E.4 · Item RBT-E01

Sources: UNL: Data Without Tears Summary, p. 1, measurable descriptions; p. 2, measurement flowchart; BACB RBT Ethics Code (2.0), §2.02.

Correct: B. "Without replacement" means the chosen item does not come back. The remaining items are rearranged and presented again, and the sequence of selections produces a ranking.

A and C return the selected item, which conflicts with “without replacement” in this round. D stops after one trial, which gives you one selection instead of a hierarchy — and a single selection tells you little, since the client may simply have grabbed what was closest. Rearranging positions helps the team detect and reduce position effects; persistent side bias still needs the supervisor’s attention.

Review takeaway: In multiple stimulus without replacement, the chosen item does not come back.

Content area B · Behavior Assessment · Task B.1 · Item RBT-B01

Sources: EBIP: Multiple Stimulus without Replacement, Overview and numbered procedure: access, removal, subsequent array and positions.

Correct: B. Hands flat on the table physically cannot happen at the same time as picking at the arm. Reinforcing a response that is physically incompatible with the target is DRI.

A is the broader category — any appropriate alternative — and DRI is the subtype that adds the incompatibility requirement, so DRI is the more precise answer here. C would reinforce the absence of picking regardless of what the client did instead. D reinforces a lower rate of a behavior you want to keep, which does not describe skin picking.

Review takeaway: DRI is DRA with one extra requirement: the reinforced response physically cannot co-occur with the target.

Content area D · Behavior Reduction · Task D.3 · Item RBT-D02

Sources: EBIP: Differential Reinforcement, Types: DRA, DRI and DRO; interval versus momentary DRO; UNL ASD Network: Differential Reinforcement, How To Use: differential reinforcement of low rates (DRL) definition.

Correct: B. Teaching begins at the last step and works backward, so the client completes the last step and receives the reinforcement specified in this plan.

A starts at step 1. C has the client attempt all seven steps each trial with prompts wherever they're needed. D isn't chaining at all — shaping reinforces closer and closer approximations of one response, not a sequence of different responses.

Review takeaway: Backward chaining ends every trial with the learner completing the task.

Content area C · Behavior Acquisition · Task C.5 · Item RBT-C03

Sources: AFIRM: Task Analysis evidence-based practice packet, PDF pp. 6–8; especially p. 7, Step 2.2.

Correct: C. Latency is the time from the antecedent event — here, the instruction — to the start of the response.

A measures how long the response lasts once it starts. B measures the gap between successive responses, rather than the instruction-to-response interval asked for here. D measures how often, not how quickly. All four are continuous measures; the question is which one answers the supervisor's actual question.

Review takeaway: Latency starts at the antecedent. Duration starts at the response.

Content area A · Data Collection and Graphing · Task A.1 · Item RBT-A03

Sources: UNL: Data Without Tears Summary, p. 1, measurable descriptions; p. 2, measurement flowchart; BACB RBT Test Content Outline (3rd ed.), A.1.

Correct: C. The RBT Ethics Code (2.0) standard 1.11 sets a specific ceiling: RBTs do not give or accept gifts from clients, stakeholders, or supervisors with a value of more than $10 US (or equivalent purchasing power). A $25 card is over that line. The same standard says that where an employer's policy is stricter, the RBT follows the employer's policy.

A is the trap — being a thank-you does not make an over-limit gift acceptable. Gifts worth $10 or less are not automatically acceptable either: they must meet the code’s conditions, and repeated gifts and stricter employer rules can matter. B and D still accept an over-limit gift; passing it to coworkers or the clinic doesn't change what was accepted. Declining warmly, and briefly saying why, protects the relationship and the rule at the same time.

Review takeaway: The code's line is $10, and a stricter employer policy overrides it.

Content area F · Ethics · Task F.8 · Item RBT-F02

Sources: BACB RBT Ethics Code (2.0), §1.11.

Correct: A. The client has met the written exchange requirement. Delivering the agreed exchange now follows both the amount and timing specified in the plan.

B breaks the contingency at the moment it matters most. C changes the schedule, which is a program decision for the supervisor, not a mid-session adjustment for the RBT. D is generous and still wrong: it hands over far more than the plan specifies. If the client is earning faster than expected, that's information to report — not a reason to redesign the plan on the spot.

Review takeaway: Deliver the token exchange at the amount and time the plan specifies.

Content area C · Behavior Acquisition · Task C.11 · Item RBT-C04

Sources: OpenStax Psychology 2e: Operant Conditioning, Reinforcement and punishment; Shaping; Primary and Secondary Reinforcers; Reinforcement Schedules; BACB RBT Ethics Code (2.0), §2.02; fictional exchange rule supplied in the stem.

Correct: B. Extinction means the behavior no longer produces its maintaining reinforcer. Here, the specified consequence is the adult comment, and B describes withholding that consequence after tapping.

A still delivers the attention identified in the assessment, even though the comment is corrective. C changes a different consequence and does not describe the written attention-extinction component. D goes beyond the plan: extinction for one response is not an instruction to ignore communication or safety needs. Raise uncertainty with the supervisor before improvising, and follow applicable safety procedures immediately when needed.

Review takeaway: Name the maintaining consequence. Extinction stops that consequence for the specified response, not care for the person.

Content area D · Behavior Reduction · Task D.4 · Item RBT-D03

Sources: AFIRM: A Case for EXT, Written introductory definition; BACB RBT Ethics Code (2.0), §§1.06, 2.01, 2.07.

Correct: B. Reporting and documenting variables that might affect client progress — illness, medication, schedule changes — in a timely way is part of the RBT's job. The supervisor needs it to interpret the data correctly; without it, a bad week looks like a failing program.

A waits for a problem that the information is supposed to explain, and by then the data are already ambiguous. C asks the RBT to make a medication recommendation outside the role. D confuses confidentiality with recordkeeping: the information belongs in the clinical record and goes to the supervisor, not into conversation with anyone else.

Review takeaway: Context goes into the record the day you hear it, not after the data look strange.

Content area E · Documentation and Reporting · Task E.3 · Item RBT-E02

Sources: BACB RBT Test Content Outline (3rd ed.), E.3; BACB RBT Ethics Code (2.0), §§1.06, 2.02, 2.06.

Correct: D. It names the specific movements that count and sets a boundary another observer can apply without guessing.

A requires predicting harm. B requires reading the client's emotional state. C requires inferring intent, which nobody can observe. Each of those puts a judgment call inside the definition, and that judgment is exactly where two observers drift apart. A definition is doing its job when two people watching the same minute produce the same number.

Review takeaway: A good operational definition removes the judgment call from the observer.

Content area A · Data Collection and Graphing · Task A.5 · Item RBT-A04

Sources: IRIS: Behavior Assessment—Frequency and Interval Recording, pp. 1–2; operational definitions, rate formula, whole/partial interval rules; UNL: Data Without Tears Summary, p. 1, measurable descriptions; p. 2, measurement flowchart.

Correct: A. A discrete trial is a structured unit: a clear instruction, a prompt where the procedure calls for one, the client's response, the programmed consequence, then a short intertrial interval before the next one.

B describes naturalistic teaching. C describes noncontingent reinforcement. D describes shaping. Note that the intertrial interval isn't dead time — it's what marks the end of one opportunity and the start of the next.

Review takeaway: Instruction, response, planned consequence, pause — then the next trial.

Content area C · Behavior Acquisition · Task C.3 · Item RBT-C05

Sources: AFIRM: A Case for DTT, Written introductory definition.

Correct: D. Reinforcement delivered on a time-based schedule and not contingent on any particular response is noncontingent reinforcement. In this plan, attention is available independently of disruption; the schedule is intended to reduce the value of obtaining it through disruption.

A makes reinforcement depend on an absence criterion; this plan makes delivery independent of the target behavior. Some DRO schedules reset a timer, but not all do. B discontinues the maintaining consequence after the target response; it does not mean withholding that consequence under every circumstance. C removes an earned reinforcer after a behavior. The giveaway phrase is "regardless of what the client is doing."

Review takeaway: “Regardless of what the client is doing” is the phrase that identifies noncontingent delivery.

Content area D · Behavior Reduction · Task D.2 · Item RBT-D04

Sources: National Center on Intensive Intervention: Reinforcement Strategies, Printed p. 5, Non-Contingent Reinforcement—Purpose and Overview; EBIP: Differential Reinforcement, Types: DRA, DRI and DRO; interval versus momentary DRO; AFIRM: A Case for EXT, Written introductory definition.

Correct: C. Descriptive assessment documents the environment as it usually operates. If the observer starts delivering consequences, the data describe the observer instead of the classroom.

A is false — RBTs participate in components of functional assessment procedures, including collecting descriptive data. B misapplies a real principle; ordinary intervention isn't a rights violation, it's a measurement problem here. D describes nothing. If a safety issue arises mid-observation, you act — safety outranks data every time — and you report that the observation was interrupted.

Review takeaway: Descriptive assessment records the environment as it normally runs — which is why the observer stays out of it.

Content area B · Behavior Assessment · Task B.3 · Item RBT-B02

Sources: EBIP: Challenging Behavior as Communication, ABC descriptions and hypothesis discussion; BACB RBT Test Content Outline (3rd ed.), B.3; BACB RBT Ethics Code (2.0), §2.07.

Correct: D. The RBT Ethics Code (2.0) says RBTs provide services only after their supervisor confirms they have demonstrated competence (1.06), and do not use unfamiliar interventions without proper training (2.04). When asked to do something beyond that, the code says to inform the supervisor or other appropriate individuals at the workplace immediately and document it.

A performs an untrained procedure on a client, which is the risk the standard exists to prevent. B is well-intentioned but a peer explanation isn't the supervisor's verification of competence, and feeding protocols carry real safety risk. C quietly drops part of a plan and hides it, which also violates the requirement to implement services accurately and report honestly (2.02, 3.02). The supervisor being unavailable doesn't remove the requirement — it just changes who you escalate to.

Review takeaway: Competence is something your supervisor verifies, not something willingness supplies.

Content area F · Ethics · Task F.2 · Item RBT-F03

Sources: BACB RBT Ethics Code (2.0), §§1.06, 2.04.

Correct: A. Reinforcement moves to successively closer approximations of one target response. That is shaping.

B teaches a sequence of different responses linked together, not refinements of a single one. C teaches responding in the presence of one stimulus and not another. D gradually removes an added feature of the teaching stimulus. The tell for shaping is that the criterion for reinforcement keeps moving while the response stays the same response, only better.

Review takeaway: Shaping moves the criterion while the response stays one response.

Content area C · Behavior Acquisition · Task C.10 · Item RBT-C06

Sources: OpenStax Psychology 2e: Operant Conditioning, Reinforcement and punishment; Shaping; Primary and Secondary Reinforcers; Reinforcement Schedules; AFIRM: Task Analysis evidence-based practice packet, PDF pp. 6–8; especially p. 7, Step 2.2.

Correct: D. The path moves upward across sessions despite two small dips. Trend is the overall direction, not a requirement that every point be higher than the one before it.

A would require the points to hover around one level. B mistakes ordinary bounce for variability; the data range widely, but they range widely in one direction. C reverses the direction. The RBT's task is to name what the data are doing and report it; deciding what to change about the program is the supervisor's call.

Review takeaway: Trend is the direction across sessions, not a requirement that every point rise.

Content area A · Data Collection and Graphing · Task A.7 · Item RBT-A05

Sources: BACB RBT Test Content Outline (3rd ed.), A.7; original graph and data shown with the question.

Correct: A. The current outline includes extinction bursts and response variation among possible secondary effects to recognize. The observed change should be reported as a possible effect, not as proof of its cause or that it will be temporary. Describing them accurately, with the data, is what the supervisor needs.

B jumps to a conclusion the data don't support yet. C refers to a behavior reappearing after it had already dropped off, which hasn't happened here. D proposes a program change that is not the RBT's to make. Two things are worth knowing: the observations do not show whether the change will subside, and a behavior escalating in intensity is a safety question the supervisor needs to hear about now, not at the next scheduled meeting.

Review takeaway: Report secondary effects with the data. Escalating intensity is a safety message, not a status update.

Content area D · Behavior Reduction · Task D.6 · Item RBT-D05

Sources: BACB RBT Test Content Outline (3rd ed.), D.6: extinction burst and response variation; documentation/safety response supported by the Ethics Code; BACB RBT Ethics Code (2.0), §§2.06–2.07.

Correct: B. Seeking and prioritizing clinical direction from a supervisor in a timely way is a defined part of the role, and two sessions of improvisation is already a delay worth closing today.

A makes the improvisation permanent and quietly turns it into the program. C puts a clinical decision on a caregiver, who is not the supervisor. D delays needed direction until a scheduled meeting. The RBT should not continue an unsafe or unfamiliar procedure while waiting; use the appropriate clinical and safety chain promptly. The honest version of the message includes what you already did, not just what you're unsure about.

Review takeaway: Two sessions of improvising is already late.

Content area E · Documentation and Reporting · Task E.2 · Item RBT-E03

Sources: BACB RBT Test Content Outline (3rd ed.), E.2; BACB RBT Ethics Code (2.0), §§1.06, 2.04, 2.06–2.07.

Correct: D. The skill exists under one narrow set of conditions. Generalization is programmed by deliberately varying the stimuli, settings, and people, not assumed to appear on its own.

A strengthens responding in the setting that already works. B treats an acquisition problem the client doesn't have — they know the signs. C measures whether the skill lasts over time, which is maintenance, a different question from whether it transfers. Choose the procedure aimed at the gap you actually observed.

Review takeaway: Generalization is programmed, not hoped for.

Content area C · Behavior Acquisition · Task C.8 · Item RBT-C07

Sources: Stokes and Baer: An Implicit Technology of Generalization, Abstract; named programming approaches including sufficient exemplars and natural maintaining contingencies; BACB RBT Test Content Outline (3rd ed.), C.8–C.9.

Correct: A. The RBT Ethics Code (2.0) standard 1.10 requires RBTs to avoid multiple relationships with clients, coworkers, and supervisors, and — when one develops — to inform the supervisor immediately, work to resolve it, and document the actions taken. When the multiple relationship involves the supervisor, the code directs the RBT to report it to that supervisor's manager or another appropriate entity, such as human resources.

B assumes good intentions solve a structural problem; they do not remove the conflict created by a family and supervisory relationship. C creates a paperwork fiction, with someone attesting to supervision they didn't provide. D waits for damage before acting. Raising it early is the low-drama version of this problem.

Review takeaway: Raise a multiple relationship before it has cost anyone anything.

Content area F · Ethics · Task F.7 · Item RBT-F04

Sources: BACB RBT Ethics Code (2.0), §1.10.

Correct: D. The behavior leaves a lasting result the RBT can score afterward. Permanent product recording can capture the accuracy of the completed work without continuous observation. It does not reveal every attempt, how long the client worked, or any unobserved assistance.

A samples whether the client is writing, not whether the writing is accurate. B measures how long, not how correct. C measures how quickly the client started. When the behavior produces something you can count later, count that.

Review takeaway: A permanent product can be scored later, but it only tells you what the product preserves.

Content area A · Data Collection and Graphing · Task A.3 · Item RBT-A06

Sources: UNL: Data Without Tears Summary, p. 1, measurable descriptions; p. 2, measurement flowchart.

Correct: A. For this client, the new chip has no established reinforcing function. Pairing it with established reinforcers is intended to develop that learned function; the team still checks its effect on responding.

B describes reducing how often reinforcement is delivered, which isn't what changes here. C describes a preference assessment. D describes prompt fading, which involves assistance, not reinforcers. This is also why token systems fall apart when the backup reinforcer stops mattering — the conditioning depends on the pairing holding up.

Review takeaway: A token means nothing until it has been paired with something that already works.

Content area C · Behavior Acquisition · Task C.2 · Item RBT-C08

Sources: OpenStax Psychology 2e: Operant Conditioning, Reinforcement and punishment; Shaping; Primary and Secondary Reinforcers; Reinforcement Schedules; EBIP: Preference Assessments, Overview; difference between a highly preferred item and a reinforcer.

Correct: C. The RBT Ethics Code (2.0) standard 2.05 sets two conditions for restrictive or punishment-based procedures, and both must be met: the procedure is in a documented behavior-change plan, and the supervisor has verified the RBT's competence. Here only the first condition is satisfied.

A treats the written plan as sufficient on its own. B makes severity the trigger, which inverts the rule — the more restrictive the situation, the more the verification matters. D moves a professional requirement onto a caregiver. Raising this isn't obstruction; it's the step that gets you trained.

Review takeaway: Restrictive procedures need both conditions: the written plan and verified competence.

Content area D · Behavior Reduction · Task D.5 · Item RBT-D06

Sources: BACB RBT Ethics Code (2.0), §2.05.

Correct: D. When selections track position rather than item, the data describe where things were, not what the client likes. Counterbalancing positions helps distinguish position effects from item preference; it does not guarantee that persistent side bias disappears.

A explains the pattern with preference when the pattern points away from preference. B gives up on a fixable procedural issue. C asserts satiation without enough evidence. Record the position pattern and follow the assessment protocol; if a side bias persists, the supervisor may need to adjust the assessment.

Review takeaway: Rotate the positions, or you measure the table instead of the client.

Content area B · Behavior Assessment · Task B.1 · Item RBT-B03

Sources: EBIP: Paired Stimulus, Overview and position-bias guidance.

Correct: A. Naturalistic teaching uses the client's existing motivation in a real activity, and the natural outcome of the response is the consequence — here, actually getting help.

B is discrete-trial teaching, which is a legitimate procedure but not this one. C turns a functional request into a drill separated from the moment when help is needed. D unnecessarily restricts teaching to scheduled work periods rather than the useful opportunity in the activity. When the plan names a teaching format, the format is part of the plan, not a suggestion.

Review takeaway: Naturalistic teaching borrows motivation that is already in the room.

Content area C · Behavior Acquisition · Task C.4 · Item RBT-C09

Sources: EBIP: Natural Environment Teaching and Naturalistic Instruction, Core Principles; naturally occurring and embedded opportunities; natural consequences.

Correct: C. 14 ÷ 20 = 0.70, which is 70%.

A reports the number of errors, not a percentage. B and D are near misses of the kind a rushed mental calculation produces. You will not have a calculator at the test center, so practice these by hand: a fraction over 20 becomes a percentage by multiplying both parts by 5.

Review takeaway: Practise these by hand. There is no calculator at the test center.

Content area A · Data Collection and Graphing · Task A.6 · Item RBT-A07

Sources: BACB RBT Test Content Outline (3rd ed.), A.6; arithmetic shown; BACB RBT Handbook, Printed pp. 11–12; prohibited personal items and supplied examination materials.

Correct: D. Communicating concerns and suggestions from the intervention team — caregivers included — to the supervisor in a timely way is a defined RBT task. A device that works in one setting and not another is exactly the kind of information that changes a program.

A and C both honor a request the RBT isn't in a position to honor, and C adds a private note nobody will act on. B deflects a concern that is squarely about the client's programming. Being transparent about what you pass along, and why, is usually what keeps caregivers comfortable telling you things.

Review takeaway: Relay the concern, and tell the person who raised it who will follow up.

Content area E · Documentation and Reporting · Task E.1 · Item RBT-E04

Sources: BACB RBT Test Content Outline (3rd ed.), E.1; BACB RBT Ethics Code (2.0), §2.06.

Correct: A. Standard 2.09 is written broadly: RBTs do not share identifying information about clients — photos, videos, or written information — on social media or websites. This photograph includes the client’s name, so the absence of a face does not make it nonidentifying.

B ignores the identifying name visible in the photograph. C assumes a caregiver can waive a professional requirement. D treats an audience setting as a safeguard, which it isn't once the post exists. Task F.6 in the exam blueprint also addresses public statements about professional activities.

Review takeaway: Do not post identifying client information. Removing a face does not remove a visible name.

Content area F · Ethics · Task F.6 · Item RBT-F05

Sources: BACB RBT Ethics Code (2.0), §2.09; BACB RBT Test Content Outline (3rd ed.), F.6: public statements about professional activities.

Correct: C. Reinforcement is contingent on the absence of the target behavior for a specified interval, with a reset when it occurs. That is differential reinforcement of other behavior.

A would specify a particular alternative response to reinforce; nothing here names one. B reinforces the behavior occurring at a lower rate rather than not at all. D would deliver the music on the timer regardless of behavior, which is precisely what the reset rule prevents. The reset is the signal to look for.

Review takeaway: This DRO requires a full interval without the target. A reset belongs to this plan, not every DRO schedule.

Content area D · Behavior Reduction · Task D.3 · Item RBT-D07

Sources: EBIP: Differential Reinforcement, Types: DRA, DRI and DRO; interval versus momentary DRO.

Correct: B. Reinforcement is available for responding in the presence of one stimulus and not another. That differential arrangement is how discrimination training builds stimulus control.

A refines a single response toward a target form. C is not established merely because touching blue is not reinforced; extinction requires discontinuing a consequence that previously maintained that response. The full arrangement here differentially reinforces the response to the named color. D involves a sequence of steps from a task analysis. Naming the whole procedure by one of its halves is a common wrong turn.

Review takeaway: Discrimination training is reinforcement in one condition and not the other.

Content area C · Behavior Acquisition · Task C.6 · Item RBT-C10

Sources: OpenStax Psychology 2e: Operant Conditioning, Reinforcement and punishment; Shaping; Primary and Secondary Reinforcers; Reinforcement Schedules; AFIRM: A Case for EXT, Written introductory definition; BACB RBT Test Content Outline (3rd ed.), C.6; fictional discrimination arrangement supplied in the stem.

Correct: C. Whole-interval recording scores an interval only when the behavior occurs for the entire interval, which matches the question about engagement throughout each interval.

A scores an interval for a single brief occurrence, so it would credit a client who engaged for two seconds. B samples only at the moment each interval ends. D counts episodes, which doesn't describe continuous engagement well. The result is not an exact percentage of time engaged. Engagement during only part of an interval receives no whole-interval credit, so interpreting the percentage as duration can underestimate time. Whether that loss of information is acceptable depends on the measurement purpose, not simply on wanting behavior to increase.

Review takeaway: Whole-interval recording credits only complete intervals. Do not report it as exact time engaged.

Content area A · Data Collection and Graphing · Task A.2 · Item RBT-A08

Sources: IRIS: Behavior Assessment—Frequency and Interval Recording, p. 2; whole-interval rule and interval-percentage calculation.

Correct: A. Assisting with a skill assessment means running it the way the protocol specifies and reporting what happened. The discrepancy between assessment performance and session performance is useful information for the supervisor — but only if the assessment data are left intact.

B, C, and D all edit the results to match what the RBT believes is true. Prompting an item that this protocol scores as independent would inflate that score; scoring from memory replaces data with recollection; re-presenting until correct changes the procedure. Document the observation and let the supervisor decide what it means.

Review takeaway: Run the protocol as written and report the discrepancy. Don't edit the result toward what you believe.

Content area B · Behavior Assessment · Task B.2 · Item RBT-B04

Sources: BACB RBT Test Content Outline (3rd ed.), B.2; BACB RBT Ethics Code (2.0), §2.02; fictional assessment protocol supplied in the stem.

Correct: B. Crisis and emergency procedures exist precisely so nobody has to invent a response under pressure. When a trained, written procedure applies, that procedure is the first action.

A puts data collection ahead of safety; documentation happens, but after. C delays the trained immediate safety response to make a caregiver call; any required caregiver notification follows the emergency protocol. D applies a routine behavior-reduction procedure to a situation the plan has already classified as a crisis. Documentation and a report to the supervisor follow — and if there's no written crisis procedure for a behavior this severe, that's something to raise before it happens again.

Review takeaway: The trained crisis procedure comes first. Documentation follows.

Content area D · Behavior Reduction · Task D.7 · Item RBT-D08

Sources: BACB RBT Test Content Outline (3rd ed.), D.7; BACB RBT Ethics Code (2.0), §§2.01, 2.07.

Correct: C. This plan aims to minimize errors by prompting immediately at first, then transferring stimulus control through its specified fading procedure.

A introduces a delay, which invites the error the procedure is designed to avoid — though a zero-second delay that grows over trials is a related procedure. B waits for an error, which conflicts with this plan’s initial zero-second prompt. D describes shaping. Fading is not optional here: prompting immediately and never fading produces a client who waits for the prompt.

Review takeaway: Prompt at the time the plan specifies, then fade according to its criteria.

Correct: D. RBTs may practice only under ongoing supervision from a supervisor who meets BACB requirements and is on record with the BACB. The BACB requires supervision for at least 5% of the hours spent delivering services each calendar month, alongside other supervision requirements, and RBTs are required to self-report supervision noncompliance. Arranging future supervision does not authorize continuing unsupervised services now.

A treats old documents as supervision, which they aren't. B lets a six-week gap become a longer one. C invents an arrangement the requirements don't allow — a supervisor needs enough client-specific knowledge to direct the work, and the relationship has to be on record. Substantial noncompliance can end a certification, so the uncomfortable conversation is the cheaper option.

Review takeaway: No supervisor on record with the BACB means you may not practise.

Sources: BACB RBT Handbook, Printed pp. 15–17 and 23; supervision and noncompliance self-report; BACB RBT Ethics Code (2.0), §§1.03, 3.01.

Correct: B. Unreliable data don't just make a messy graph. They feed a decision. A supervisor looking at an apparent drop may end a procedure that was working, or keep one that wasn't, because the pattern tracks the observer rather than the behavior.

A describes an effect on the client's learning environment, which is a procedural-fidelity concern rather than a measurement one. C and D are possible workplace consequences, not the risk to the client. The fix is a shared operational definition and a check that both observers apply it the same way.

Review takeaway: Unreliable data can produce a bad decision, not just a messy graph.

Content area A · Data Collection and Graphing · Task A.8 · Item RBT-A09

Sources: BACB RBT Test Content Outline (3rd ed.), A.8; BACB RBT Ethics Code (2.0), §2.02.

Correct: C. Maintenance procedures ask whether a previously mastered skill persists over time after active teaching is reduced or ends; ordinary reinforcement can still occur. That's why the probe deliberately withholds prompts and correction — adding them would measure teaching, not maintenance.

A targets faster performance rather than persistence over time. B describes what you'd do if the skill had already fallen apart. D tests transfer to new conditions, which is a different question: a client can maintain a skill perfectly in one setting and still not transfer it. Knowing which of the two you're measuring keeps you from drawing the wrong conclusion from a low score.

Review takeaway: Maintenance asks whether it lasts. Generalization asks whether it transfers.

Content area C · Behavior Acquisition · Task C.9 · Item RBT-C12

Correct: D. Records should be accurate and complete, and corrections are made openly. A dated addition shows both what happened and when it was documented, which is what keeps the record honest.

A attaches an event to the wrong session. B leaves a knowingly incomplete record, which conflicts with the requirement to complete documentation accurately. C hides the RBT's own omission behind someone else's signature. What would make this genuinely serious is editing the original to look as though it was written during the session — that's falsification, not a correction.

Review takeaway: Correct omissions transparently under the record-correction policy; do not make a late entry look contemporaneous.

Content area E · Documentation and Reporting · Task E.4 · Item RBT-E05

Sources: BACB RBT Ethics Code (2.0), §§1.01, 2.02; fictional correction policy supplied in the stem.

Correct: A. A communication response is taught that produces the same reinforcer — escape — that the problem behavior produced, while the problem behavior is placed on extinction. The functionally equivalent communication response identifies functional communication training. This particular plan also includes extinction.

B delivers reinforcement on a schedule independent of behavior. C removes an earned reinforcer following behavior. D would arrange different consequences in the presence of different stimuli. The word "functional" in the name is the point: the replacement has to get the client the same thing, or it won't compete.

Review takeaway: The replacement response has to buy the client the same thing the problem behavior bought.

Content area D · Behavior Reduction · Task D.3 · Item RBT-D09

Sources: AFIRM: A Case for FCT, Written introductory definition; EBIP: Differential Reinforcement, Types: DRA, DRI and DRO; interval versus momentary DRO.

Correct: C. Preference and reinforcement are different things. A preference assessment identifies what a client is likely to choose; whether an item functions as a reinforcer is defined by whether behavior it follows increases. Here it didn't.

A blames the procedure without evidence — the ranking may have been accurate at the time. B attributes the result to the client rather than the arrangement. D changes the teaching procedure without the supervisor evaluating the result and other variables that may affect it. This is one of the most useful distinctions in the role, and the reason preference assessments get repeated.

Review takeaway: Preference is a useful lead. Check whether contingent access actually strengthens the target response.

Content area B · Behavior Assessment · Task B.1 · Item RBT-B05

Sources: EBIP: Preference Assessments, Overview; difference between a highly preferred item and a reinforcer; OpenStax Psychology 2e: Operant Conditioning, Reinforcement and punishment; Shaping; Primary and Secondary Reinforcers; Reinforcement Schedules.

Correct: B. A fixed-ratio schedule delivers reinforcement after a set number of responses. FR-4 means every fourth one.

A describes response-independent, fixed-time delivery, not a requirement for four correct responses. C describes a variable-ratio schedule, where the count varies around an average. D describes the size of the reinforcer, not the schedule. Ratio means responses, interval means time — and "fixed" or "variable" tells you whether the requirement is constant or moves around.

Review takeaway: Ratio schedules count responses. Interval schedules count time.

Content area C · Behavior Acquisition · Task C.1 · Item RBT-C13

Sources: OpenStax Psychology 2e: Operant Conditioning, Reinforcement and punishment; Shaping; Primary and Secondary Reinforcers; Reinforcement Schedules; National Center on Intensive Intervention: Reinforcement Strategies, Printed p. 5, Non-Contingent Reinforcement—Purpose and Overview.

Correct: A. Duration records how long each episode lasts, which is exactly the dimension in question.

B counts episodes, and the supervisor has already said the count is roughly unchanged. C measures how long after an antecedent the behavior starts. D measures the gaps between episodes. Behaviors change on more than one dimension, and a program can be working on duration while frequency stays flat — which is invisible unless someone measures the right one.

Review takeaway: Ask which dimension of the behavior changed before you pick a measure.

Content area A · Data Collection and Graphing · Task A.1 · Item RBT-A10

Sources: UNL: Data Without Tears Summary, p. 1, measurable descriptions; p. 2, measurement flowchart.

Correct: C. The professional skills the blueprint names include accepting feedback, listening actively, seeking input, and collaborating — and the Ethics Code says RBTs take action to improve performance following supervisor feedback (2.03). None of that requires pretending to agree. Implement the direction, then bring your data.

A is performing compliance for an audience, and it also means the client gets two different procedures. B routes a supervision issue to a peer who wasn't there. D complies but throws away information the supervisor would probably want. Disagreement raised through the right channel is part of the job; silent noncompliance is not.

Review takeaway: Apply the understood, safe direction and bring your observations to the supervisor.

Content area F · Ethics · Task F.9 · Item RBT-F07

Sources: BACB RBT Ethics Code (2.0), §2.03; BACB RBT Test Content Outline (3rd ed.), F.9.

Correct: B. A short run of high-probability requests delivered right before a low-probability one is an antecedent intervention aimed at increasing compliance with the harder demand.

A refines one response toward a target. C reinforces an alternative to a problem behavior, which isn't the arrangement here. D links steps of one task into a sequence; these three requests aren't steps of the writing task. The defining arrangement is a short sequence of likely-to-be-completed requests immediately before a less likely one. The team still evaluates whether this plan helps this client.

Review takeaway: High-probability means likely to be completed. Follow the planned sequence and check its effects.

Content area D · Behavior Reduction · Task D.2 · Item RBT-D10

Sources: AFIRM: Behavioral Momentum Intervention, Behavioral Momentum Intervention entry.

Correct: D. Progressive time delay starts with no delay between instruction and prompt and stretches the wait across trials, giving the client an expanding opportunity to respond before help arrives.

A describes constant time delay, where the delay is the same on every trial after the initial zero-second trials. B is error correction. C describes schedule thinning, which concerns reinforcement rather than prompts. Both delay procedures are ways to transfer stimulus control from the prompt to the natural instruction — they just differ in how the wait is scheduled.

Review takeaway: Constant delay holds the wait steady. Progressive delay stretches it.

Content area C · Behavior Acquisition · Task C.7 · Item RBT-C14

Sources: EBIP: Progressive Time Delay, Overview; initial zero-second and later delay procedures.

Correct: A. It records what the RBT observed and what was not observed. The Ethics Code requires accurate documentation (2.02) and protective action when there is a risk of harm (2.07). An objective note does not replace any reporting duty that applies under the law where the RBT works (2.01).

B asserts a cause that the RBT did not observe. C makes an unsupported safety judgment and dismisses follow-up. D supplies a plausible story, not evidence. Record observations and actions accurately; follow applicable reporting obligations without conducting your own investigation or waiting for proof.

Review takeaway: Record what you observed, distinguish what you do not know, and follow the applicable protective and reporting duties.

Content area E · Documentation and Reporting · Task E.4 · Item RBT-E06

Sources: BACB RBT Ethics Code (2.0), §§2.01–2.02, 2.07.

Correct: C. Entering data and keeping graphs current is a named part of the role, and doing it while the session is fresh is how transcription errors get caught rather than multiplied.

A puts a week of clinical decisions on a memory-and-paperwork sprint the night before. B decides which data count, which is not a call the person collecting them makes. D shifts an assigned RBT task to the supervisor. RBTs can also identify and report graph patterns; clinical program decisions remain with the supervisor. A graph missing four days of collected data may omit information needed for today’s decision.

Review takeaway: Keep the graph current under the program’s requirements so recent observations are available for decisions.

Content area A · Data Collection and Graphing · Task A.4 · Item RBT-A11

Sources: BACB RBT Test Content Outline (3rd ed.), A.4–A.7; BACB RBT Ethics Code (2.0), §2.02; fictional entry schedule supplied in the stem.

Correct: B. Cultural humility and responsiveness is a named exam task, and the Ethics Code asks RBTs to work directly with their supervisor to ensure their work is culturally responsive (1.07). Bring the observation and let the plan change through the person who can change it.

A treats the family's practices as irrelevant to a procedure happening in their home. C substitutes a consequence without clinical direction. That does not mean continuing a procedure over a caregiver’s refusal: respect the refusal and obtain direction promptly. D asks the family to accommodate the program instead of the reverse. The family’s practices are relevant information for designing a workable plan.

Review takeaway: Bring the family’s preferences into planning; do not treat a written procedure as permission to disregard a refusal.

Content area F · Ethics · Task F.10 · Item RBT-F08

Sources: BACB RBT Ethics Code (2.0), §§1.07, 2.01, 2.06.

Correct: D. Every step is attempted on every trial, with prompting targeted to the steps that need it. That's total-task presentation, and it suits a client who already performs most of the chain.

A and B introduce teaching through a designated end of the chain, rather than having the learner attempt the entire sequence on every trial as stated here. C isn't a chaining procedure. The supervisor selects the teaching approach; the RBT identifies and implements the format written in this plan.

Review takeaway: Total-task presentation offers every step on each trial, with the planned help where needed.

Content area C · Behavior Acquisition · Task C.5 · Item RBT-C15

Sources: AFIRM: Task Analysis evidence-based practice packet, PDF pp. 6–8; especially p. 7, Step 2.2.

Correct: D. Procedural consistency matters, and it does not outrank client safety. When behavior escalates to a risk of injury, the safety provisions of the plan govern, and the supervisor needs to hear about it before the next session — a plan that produces an unsafe escalation needs review.

A holds the line past the point where holding the line is the RBT's call to make. B introduces a procedure the RBT hasn't been authorized or verified to run. C leaves a client engaging in self-injury unsupervised. "Follow the plan as written" is the right default and the reason plans include crisis provisions: so the exception is also written down.

Review takeaway: Safety provisions are part of the plan, not a departure from it.

Content area D · Behavior Reduction · Task D.4 · Item RBT-D11

Sources: BACB RBT Ethics Code (2.0), §§2.01, 2.07; BACB RBT Test Content Outline (3rd ed.), D.4, D.7.

Correct: A. The exam blueprint names participating in components of functional assessment procedures, including descriptive assessment and functional analysis, as an RBT task. Running an assigned condition under the supervisor's direction is exactly that.

B is over-cautious in a way that gets the role wrong. C alters a condition mid-analysis, which destroys the comparison the analysis depends on — a higher rate can be relevant assessment data, but safety thresholds still apply. D asks the RBT to determine the function from the analysis independently. The RBT may identify and report patterns, but the supervisor is responsible for the functional conclusion. Safety concerns are the one thing you raise immediately rather than absorbing.

Review takeaway: Run only the trained, assigned condition, follow its safeguards, and report the data for the supervisor’s assessment.

Content area B · Behavior Assessment · Task B.3 · Item RBT-B06

Sources: BACB RBT Test Content Outline (3rd ed.), B.3; BACB RBT Ethics Code (2.0), §§1.03, 1.06, 2.07.

Correct: C. Total duration divided by number of episodes: 20 + 35 + 15 + 50 = 120 seconds, and 120 ÷ 4 = 30 seconds.

A is the total, not the mean. B and D do not equal the total of 120 seconds divided by four episodes. Mean duration answers a different question from total duration — a client can hold total crying steady while episodes get shorter and more frequent, and only one of those measures shows it.

Review takeaway: Mean duration and total duration answer different questions.

Content area A · Data Collection and Graphing · Task A.6 · Item RBT-A12

Sources: BACB RBT Test Content Outline (3rd ed.), A.6; calculation shown.

Correct: B. A stimulus was removed contingent on the behavior, and the behavior increased. That's negative reinforcement, and it's a deliberate, legitimate teaching arrangement here — completing work earns an end to work.

A would involve adding something, like praise or a token. C would mean the behavior no longer produces its reinforcer. D would require the behavior to decrease. "Negative" in this vocabulary means subtraction, not unpleasantness.

Review takeaway: “Negative” means something was removed, not that something was unpleasant.

Content area C · Behavior Acquisition · Task C.1 · Item RBT-C16

Sources: OpenStax Psychology 2e: Operant Conditioning, Reinforcement and punishment; Shaping; Primary and Secondary Reinforcers; Reinforcement Schedules.

Correct: D. These four are named in the introduction to the RBT Ethics Code (2.0) as the principles the individual standards rest on, and applying them is a task on the current exam blueprint.

A lists specific duties that follow from the principles rather than the principles themselves. B lists documentation qualities. C lists real and important ideas from practice, which is what makes it the attractive wrong answer — but they aren't the code's four named principles. When a question asks for the core principles, it's asking for the four.

Review takeaway: Four principles: benefit others; compassion, dignity and respect; integrity; competence.

Content area F · Ethics · Task F.1 · Item RBT-F09

Sources: BACB RBT Ethics Code (2.0), Introduction: core principles; BACB RBT Test Content Outline (3rd ed.), F.1.

Correct: A. The assessed function is escape from the writing task. A supplies that consequence by removing the task after the response. Identify the function by the relationship described in the assessment, not by the appearance of dropping to the floor.

B supplies attention, not the specified escape. C supplies access to an item, not task removal. D records the event without supplying the identified consequence. Recognizing the maintaining consequence is not authorization to add, remove, or change an intervention; the RBT follows the supervisor’s plan.

Review takeaway: Match the consequence to the assessed function. The same-looking behavior can have a different function for another person.

Content area D · Behavior Reduction · Task D.1 · Item RBT-D12

Sources: EBIP: Challenging Behavior as Communication, ABC descriptions and hypothesis discussion; BACB RBT Test Content Outline (3rd ed.), D.1; supervisor-established finding supplied in the stem.

Correct: C. Reporting and documenting variables that might affect client progress is a defined task, and illness is the standard example. The data stay as they are; the context goes in alongside them so the supervisor doesn't read a sick day as a failing program.

A leaves the supervisor with an unexplained drop. B slips into inference — "unwell and unmotivated" is a conclusion, while "caregiver reported stomach illness since yesterday and minimal food intake" is a report. D omits information that changes how the day should be read. Attribute what the caregiver told you to the caregiver, and keep your own observations separate.

Review takeaway: Attribute what the caregiver told you to the caregiver, and keep your own observations separate.

Content area E · Documentation and Reporting · Task E.3 · Item RBT-E07

Sources: BACB RBT Test Content Outline (3rd ed.), E.3; BACB RBT Ethics Code (2.0), §§2.02, 2.06–2.07.

Correct: D. The re-presentation and prompt follow this plan’s error-correction sequence. What conflicts with the plan is delivering the reinforcer earmarked for independent responding after a prompted response, because that weakens the difference the plan is trying to teach.

A and B describe ordinary error correction. C prohibits any speech after an error, which is not what this plan says. The point is to follow the specified correction and consequence procedure rather than a habit, and to ask the supervisor when the plan does not specify it.

Review takeaway: Reinforce what the plan says to reinforce, at the value the plan assigns it.

Content area C · Behavior Acquisition · Task C.3 · Item RBT-C17

Sources: AFIRM: A Case for DTT, Written introductory definition; BACB RBT Ethics Code (2.0), §2.02; fictional correction and consequence protocol in the stem.

Correct: B. Momentary time sampling records whether behavior is occurring at the assigned moment. Brief, staggered checks fit the observation constraint given here; they do not produce continuous records of all four clients.

A and C both require continuous observation of four people at once. D answers a different question and still needs close watching at the start of each opportunity. The trade-off is real and worth naming: sampling estimates rather than counts, and brief behaviors can fall between the sampling moments. That's the price of a measure you can actually collect.

Review takeaway: Momentary sampling buys feasibility and pays for it in precision.

Content area A · Data Collection and Graphing · Task A.2 · Item RBT-A13

Sources: Bakersfield City School District: Measuring Behavior—Interval, How to Collect the Data—Momentary Time Sampling, end-of-interval recording instruction; BACB RBT Test Content Outline (3rd ed.), A.2; assigned sampling schedule supplied in the stem.

Correct: A. The blueprint names training that includes instructions, modeling, rehearsal, and feedback, plus observation of the RBT delivering services. All five appear in A.

B provides instruction with no modeling, rehearsal, feedback, or observation. C adds a model but skips rehearsal and feedback. D is responsive but unstructured and never verifies the skill under observation. Knowing this pattern is useful in both directions: it's what you should receive, and it's what you can reasonably ask for when you're handed something new.

Review takeaway: Instruction, modeling, rehearsal, feedback, observation. Ask for all five.

Sources: DiGennaro Reed et al.: Guidelines for Using Behavioral Skills Training to Provide Teacher Support, Instruction, modeling, rehearsal, feedback sections; ongoing support; BACB RBT Test Content Outline (3rd ed.), F.4.

Correct: C. The response is under the control of one person. Programming generalization across people means building the skill with several people deliberately, rather than expecting it to spread.

A strengthens the one relationship that already works. B re-teaches a response the client has. D measures maintenance over time, which isn't the gap. Generalization comes in flavors — across people, settings, and materials — and the one you program should be the one you're missing.

Review takeaway: Program the kind of generalization you are actually missing.

Content area C · Behavior Acquisition · Task C.8 · Item RBT-C18

Sources: Stokes and Baer: An Implicit Technology of Generalization, Abstract; named programming approaches including sufficient exemplars and natural maintaining contingencies; BACB RBT Test Content Outline (3rd ed.), C.8.

Correct: D. A stimulus was removed following the behavior, and the behavior decreased. Removal plus a decrease is negative punishment — in this specific form, response cost. Time-out from reinforcement is the other common example.

A would mean the behavior stopped producing its reinforcer, which isn't what's described. B reinforces intervals without the behavior. C would require the behavior to increase. This is a punishment-based procedure, which is why they belong in a written plan and require the supervisor to verify your competence before you run them.

Review takeaway: Removed, and the behavior decreased: that is negative punishment.

Content area D · Behavior Reduction · Task D.5 · Item RBT-D13

Sources: OpenStax Psychology 2e: Operant Conditioning, Reinforcement and punishment; Shaping; Primary and Secondary Reinforcers; Reinforcement Schedules; BACB RBT Ethics Code (2.0), §2.05.

Correct: B. A free-operant assessment gives the client access to items and measures what they engage with and for how long. It needs no discrete selection from an array presented on each trial, which is what makes it the fit here.

A, C, and D all require the client to choose from a presented array — the exact response this client doesn't produce reliably. The trade-off is that the ranking reflects engagement during the observation; it does not prove that any item will function as a reinforcer. An item the client reaches first is not automatically the most preferred. Choose the format the client's behavior can actually support.

Review takeaway: Free-operant assessment fits a learner who will not choose from an array.

Content area B · Behavior Assessment · Task B.1 · Item RBT-B07

Sources: EBIP: Free Operant Observation, Overview and observation procedure; EBIP: Preference Assessments, Overview; difference between a highly preferred item and a reinforcer.

Correct: A. Tokens are only worth what they buy. A change in the value of the backup reinforcer is one possible explanation to report, not a cause proved by this description. The supervisor may want a fresh preference assessment or a menu of backups.

B makes an already-weak reinforcer harder to earn. C changes delivery without finding out why responding changed. D abandons the system without that evaluation. Bring the observations and the possible backup-reinforcer issue to the supervisor rather than diagnosing the cause or blaming the client.

Review takeaway: When tokens stop working, look at what they buy before you look at the client.

Content area C · Behavior Acquisition · Task C.11 · Item RBT-C19

Sources: OpenStax Psychology 2e: Operant Conditioning, Reinforcement and punishment; Shaping; Primary and Secondary Reinforcers; Reinforcement Schedules; EBIP: Preference Assessments, Overview; difference between a highly preferred item and a reinforcer; BACB RBT Ethics Code (2.0), §2.06.

Correct: C. Communicating concerns and suggestions from the intervention team — teachers included — to the supervisor in a timely way is a named RBT task. Telling the teacher who will follow up is what keeps it from feeling like the concern vanished.

A offers clinical recommendations the RBT isn't in a position to make. B dismisses information about the client's environment that could matter a great deal. D delays a three-week-old pattern for another two weeks. Relaying the message is the task; deciding what to do about it is the supervisor's.

Review takeaway: Teachers are part of the intervention team. Relay what they tell you.

Content area E · Documentation and Reporting · Task E.1 · Item RBT-E08

Sources: BACB RBT Test Content Outline (3rd ed.), E.1; BACB RBT Ethics Code (2.0), §2.06.

Correct: D. Assisting with skill-based assessments — preparing for the assessment, collecting data, helping with data summaries — is the RBT's part of this work.

A, B, and C are all decisions about what to assess, what the results mean, and what to do next, and all three belong to the supervisor. The line is consistent across the assessment tasks: the RBT runs the procedure and produces the data; the supervisor selects, interprets, and plans.

Review takeaway: You produce the data. The supervisor selects, interprets, and plans.

Content area B · Behavior Assessment · Task B.2 · Item RBT-B08

Sources: BACB RBT Test Content Outline (3rd ed.), B.2; BACB RBT Ethics Code (2.0), §§1.03, 1.06.

Correct: B. It's a causal conclusion about a family, drawn by someone whose role is to report what happened. The note needs observable information and properly attributed reports, not an unsupported causal judgment about a family.

A is the core of the note. C is appropriate when it's attributed rather than asserted. D is exactly what an incident entry should look like. If you believe an environmental variable is driving a plateau, that belongs in a conversation with your supervisor, framed as an observation.

Review takeaway: Opinions about a family belong in a conversation with your supervisor, not in the record.

Content area E · Documentation and Reporting · Task E.4 · Item RBT-E09

Sources: BACB RBT Ethics Code (2.0), §2.02.

Correct: D. The current outline lists escape, avoidance, and emotional responses among secondary effects of punishment that an RBT should recognize. The timing here makes this a possible effect to report, not a demonstrated cause. A client who begins avoiding the person and the materials is showing the team something the target-behavior graph won't.

A watches one number and misses the cost. B delays reporting until a meeting. Immediate protective action or a pause required by a safety or assent provision should not wait; report the concern promptly through the appropriate chain. C adds a component the RBT isn't authorized to add. Report it with data and let the supervisor weigh the trade-off — that's what the blueprint means by describing secondary effects.

Review takeaway: Watch for avoidance of you and the materials, not only the target-behavior graph.

Content area D · Behavior Reduction · Task D.6 · Item RBT-D14

Sources: BACB RBT Test Content Outline (3rd ed.), D.6: possible escape/avoidance and emotional responding; BACB RBT Ethics Code (2.0), §§2.01, 2.05–2.07.

Correct: A. The Ethics Code requires RBTs to protect confidentiality and privacy by following the requirements set by the BACB, their employer, and the law when collecting, using, storing, and disclosing client information (2.08). The employer's records procedure is part of that, and "this is how we've always done it" isn't a substitute for it.

B relies on concealment rather than a required safeguard. C assumes a personal-phone backup is authorized and adequately protected; the scenario establishes neither. D assumes a records-release arrangement without checking the required procedure. Authorized caregiver access can be appropriate, but it must use the applicable records process. When you're unsure what the requirement is, asking is the professional move, not an admission.

Review takeaway: Follow the employer's records procedure, and ask what it is if you don't know.

Content area F · Ethics · Task F.5 · Item RBT-F11

Sources: BACB RBT Ethics Code (2.0), §§2.08–2.10.

Correct: C. A new behavior that carries a risk of injury is the kind of clinical information that changes what should happen next session. Seeking and prioritizing clinical direction in a timely way is a defined RBT task, and prioritizing means recognizing which item can't wait.

A is unremarkable. B is a supply issue to solve and note. D is worth documenting and mentioning. All four can go in the record, and other issues may also need timely communication. The new injury-risk behavior is the clearest safety priority among these choices. Knowing the difference is most of what "timely" means in practice.

Review takeaway: Timely means knowing which of today's four things cannot wait.

Content area E · Documentation and Reporting · Task E.2 · Item RBT-E10

Sources: BACB RBT Test Content Outline (3rd ed.), E.2; BACB RBT Ethics Code (2.0), §2.07.

Correct: B. Four of five steps is 80% fidelity. When a procedure is not being delivered as written, a flat learner graph cannot tell you whether the procedure failed or whether it was never fully tested. The supervisor needs to address the implementation discrepancy and evaluate the learner’s data in that context.

A draws a conclusion about the procedure from an incomplete trial of it. C is the more dangerous error: poor procedural fidelity does not automatically make the learner’s observed data missing. Preserve what was actually observed and flag the implementation deviation. Only genuinely unobserved or unavailable values are missing; neither replace observed values with zeros nor erase them. A zero is a claim that the measured response did not occur or no correct responses were observed under the specified measure. D adjusts the paperwork to match what happened instead of adjusting what happens.

Review takeaway: Fidelity measures implementation. Preserve observed learner data, label deviations, and never fill a genuinely missing value with a zero.

Content area A · Data Collection and Graphing · Task A.8 · Item RBT-A14

Sources: BACB RBT Test Content Outline (3rd ed.), A.8; BACB RBT Ethics Code (2.0), §§1.01, 2.02; supplied five-step checklist and arithmetic.

Correct: B. Perfect prompted performance with zero independent responding is the signature of a prompt that never faded. Stimulus control sits with the model instead of with the instruction.

A mistakes prompted accuracy for mastery. C misreads a prompting problem as a reinforcement one. D discards a target the client may be close to acquiring. The blueprint pairs prompting with fading for this reason — prompted accuracy alone does not establish independent mastery. Report the stalled fading procedure and obtain the supervisor’s direction rather than changing it yourself.

Review takeaway: Perfect prompted performance is not independent mastery. Check the actual independent opportunities and fading plan.

Content area C · Behavior Acquisition · Task C.7 · Item RBT-C20

Sources: EBIP: System of Least Prompts, Overview and prompting sequence; EBIP: Progressive Time Delay, Overview; initial zero-second and later delay procedures.

Correct: C. Differential reinforcement of low rates reduces how often a behavior occurs without eliminating it, which is what you want when the behavior is appropriate and only the rate is a problem.

A reinforces the absence of the behavior, which would target a response the team wants to keep. B reinforces something physically incompatible with hand raising, which has the same problem. D would stop reinforcing hand raising altogether. Ask first whether the behavior should disappear or just happen less — that question selects the procedure.

Review takeaway: Ask whether the behavior should stop or only slow down. That question picks the procedure.

Content area D · Behavior Reduction · Task D.3 · Item RBT-D15

Sources: UNL ASD Network: Differential Reinforcement, How To Use: differential reinforcement of low rates (DRL) definition.

Correct: A. An employment relationship with a client's family mixes roles and creates the conflicts of interest that standard 1.10 tells RBTs to avoid. The code's instruction when one develops is to inform the supervisor, work to resolve it, and document what you did.

B treats the subject matter of the second job as the issue, when the relationship is the issue — the client’s family would also become your employer. C and D try to find a version small enough not to count. None of them remove the fact that one party now pays the other outside the clinical relationship.

Review takeaway: The second job is the problem. Its subject matter is not.

Content area F · Ethics · Task F.7 · Item RBT-F12

Correct: D. Descriptive data record what happens near the behavior. Adults respond to a lot of things, so a consequence being common does not establish that it maintains the behavior. The pattern can support a hypothesis for further assessment.

A treats a correlation as a demonstration. B changes the environment based on an untested hypothesis, which can make things worse if the function is something else. C overcorrects in the other direction; the data are consistent with an attention function, they just don't prove it. Collecting the data is the RBT's part; drawing the conclusion is the supervisor's.

Review takeaway: Common is not causal.

Correct: A. The RBT implements the token system as designed. The client's request is genuinely useful information — it names something the client may value more than the current menu — and it goes to the supervisor, who can revise the plan.

B and C both change the program, one by altering the exchange schedule and the other by altering the backup reinforcers. D shuts the door on a request that should be passed along. The pattern repeats across the role: run it as written, report what you noticed.

Review takeaway: Run it as written, report what you noticed.

Content area C · Behavior Acquisition · Task C.11 · Item RBT-C21

Correct: A. 9 independently correct responses ÷ 12 opportunities × 100 = 75%. The two prompted correct responses are not independently correct.

B counts all 11 correct responses, including the two prompted responses: 11 ÷ 12 × 100 ≈ 91.7%. C corresponds to 10 of 12, but the record contains only 9 independently correct responses. D reports the 3 opportunities that were not independently correct. Read what belongs in the numerator before you calculate.

Review takeaway: Define the numerator before calculating a percentage. Prompted correct and independently correct are different measures.

Content area A · Data Collection and Graphing · Task A.6 · Item RBT-A15

Sources: EBIP: Progressive Time Delay, Overview; initial zero-second and later delay procedures; BACB RBT Test Content Outline (3rd ed.), A.6; supplied data and calculation.

Correct: C. The task is reporting variables that might affect client progress in a timely way, and a move plus a school change is about as large as those get. Three weeks of notice is what lets the team prepare rather than react.

A waits until the change is already producing effects. B draws a line in the wrong place — a change in the client's living and school environment is squarely clinical. D turns advance warning into a retrospective explanation. Timely means while the information is still useful.

Review takeaway: Timely means while the information can still be used.

Content area E · Documentation and Reporting · Task E.3 · Item RBT-E11

Sources: BACB RBT Test Content Outline (3rd ed.), E.3; BACB RBT Ethics Code (2.0), §2.06.

Correct: C. The general emergency protocol supplied in this scenario governs the immediate safety response. A gap in the individual behavior procedure is not a reason to improvise a physical intervention or delay emergency help. Documenting and reporting afterward is what gets the gap in the plan closed.

A invents a physical procedure under pressure, which is how people get hurt. B applies a procedure designed for different behavior in different circumstances. D leaves a client in an unsafe situation. Worth checking before you need it: what your organization's protocol actually says, and who you call.

Review takeaway: Know your organization's emergency protocol before the day you need it.

Content area D · Behavior Reduction · Task D.7 · Item RBT-D16

Sources: BACB RBT Test Content Outline (3rd ed.), D.7; BACB RBT Ethics Code (2.0), §§2.01, 2.07; trained emergency protocol supplied in the stem.

Correct: D. Naturalistic teaching puts the instruction where the motivation already is, and the natural outcome of the response — getting the cup, the toy, more water — is the reinforcer.

A places the teaching in the setting the client is least invested in. B is a legitimate arrangement, but it uses water play as a reinforcer for table work rather than as a teaching context, which is a different procedure. C changes access to support table work rather than embedding the teaching in the activity, and it is not the naturalistic arrangement asked for here. When the plan says naturalistic teaching, the client's motivation sets the agenda.

Review takeaway: When the plan says naturalistic, the client's motivation sets the agenda.
