NBCOT COTA Exam Prep: Free Study Plan and 30 Practice Questions
This free guide turns NBCOT's current COTA content outline into a priority map, a six-week study plan, and 30 original practice questions, including seven select-three multi-select items. It covers the COTA (Certified Occupational Therapy Assistant) exam only; the Occupational Therapist Registered (OTR) exam has a different outline and format.
What to study first
NBCOT builds every COTA exam from its 2022 COTA content outline. Use its domain shares as a starting point, then adjust your time based on what you miss.
| Domain (2022 COTA outline) | Share of exam | What the questions ask you to do |
|---|---|---|
| 2. Select and Implement Interventions | 55% | Carry out the intervention plan under OTR supervision: preparatory methods and modalities, ADL/IADL and occupation-based strategies, grading, groups, cognitive and sensory strategies, feeding, transfers, exercise and edema control, orthoses and prostheses, assistive technology and mobility, home and workplace modifications |
| 1. Collaborate and Gather Information | 27% | Gather information under OTR supervision: development and conditions, assessments and screening, activity analysis, teamwork and health literacy, monitoring the plan and spotting precautions |
| 3. Uphold Professional Standards and Responsibilities | 18% | Evidence-based practice, quality improvement, infection control, emergencies and safety, laws, reimbursement, documentation, ethics and the NBCOT Code of Conduct |
Weights, domain names, and tasks come from the NBCOT 2022 COTA Examination Content Outline and the NBCOT Certification Exam Handbook (p. 22).
Two things the table tells you:
- Interventions are more than half the exam. Give this domain substantial practice time, then adjust your hours using the gaps you find.
- Watch the phrase "under the supervision of the OTR." It appears in the Domain 1 and Domain 2 descriptions. Many questions turn on what the COTA does, what the OTR decides, and when the COTA should report back.
If a prep source describes the current COTA exam as having 200 questions, a $515 application fee, or a 45-day retake wait, it's out of date. Check anything that matters against NBCOT.
Your 6-week NBCOT COTA study plan
Assumptions: about 11–15 hours a week, six study days, one day off. Practice questions start in week 1 so you can apply what you review. This page gives you 30 questions. The longer timed blocks below are optional and need additional, previously unseen practice from materials you already have. This is our plan, not an NBCOT requirement, and no plan can guarantee a result.
| Week | Focus (from the 2022 COTA outline) | Saturday practice block | End-of-week checkpoint |
|---|---|---|---|
| 1 | Baseline + Domain 1. Read the full outline once. OTR vs. COTA roles in evaluation and planning, typical development and aging, condition patterns, standardized vs. nonstandardized assessment, activity analysis, team roles, health literacy and caregiver training, precautions (postsurgical, vital signs, suicidal ideation) | The 30 questions on this page, untimed; start your miss log | Three topics to review next |
| 2 | Domain 2, part 1. Preparatory methods (wounds and skin, superficial heat and cold, electrical stimulation), ADL/IADL strategies, grading, groups, cognitive/perceptual/sensory strategies, chaining and cueing, joint protection and energy conservation | 48 mixed questions in 60 minutes (75 seconds each on average) | Every week-1 miss reworked |
| 3 | Domain 2, part 2. Feeding and swallowing strategies, transfers, prevocational and mental health/wellness strategies, therapeutic exercise, edema, scar and desensitization, balance and breathing during tasks, orthoses and prostheses | 95 mixed questions in 2 hours, at least 15 of them multi-select | Misses sorted by domain and by cause |
| 4 | Domain 2, part 3. Seating and mobility, high- and low-tech assistive technology, community mobility, home and workplace modifications, accessibility standards. Start mixing in Domain 1 | Optional full-length timed practice: 190 previously unseen questions in 4 hours | Two areas to review next |
| 5 | Domain 3 + repair. Evidence-based practice, quality improvement, population programs, infection control, emergencies, safety and burnout prevention, laws, practice acts, reimbursement, documentation, ethics and the NBCOT Code. Spend half the week on the two areas you chose to review after week 4 | Multi-select drills plus 95 mixed questions | Did your weak areas improve? |
| 6 | Integration. Mixed sets only, heavy on multi-select. No big new topics | A light mixed set early in the week; the last two days are logistics and rest | Final-week checklist done |
Using only this page? In week 1, answer all 30 questions before checking the explanations. In later weeks, replace the longer question blocks with review of this page's items in the week's domain: hide each answer, explain your choice and the alternatives, check the linked source, and update your miss log. Use the same process in the daily question block. Repeated items are useful for retrieval practice, but their scores are not fresh evidence of readiness. A full-length timing rehearsal needs a separate set of 190 previously unseen questions; repeating these 30 does not create one.
Your daily template
| Day | Block 1 | Block 2 | Block 3 | Time |
|---|---|---|---|---|
| Monday–Friday | 50–60 min: content for the week's focus | 25 min: 20 mixed questions at 75 seconds each on average | 20–30 min: review misses and log the cause | 95–115 minutes |
| Saturday | Timed practice block (see table) | Review every miss and every lucky guess | Set next week's priorities | About 3–5 hours (longer in week 4) |
| Sunday | Off | 0 |
A full practice exam you don't review is mostly a stamina drill. If you use week 4's full-length practice, move its review into Monday and Tuesday's content blocks.
Adapt the plan
| Your situation | How to adapt |
|---|---|
| 4 weeks until your test | Merge weeks 2 and 3, and weeks 5 and 6. Keep the optional full-length timed practice if you have the additional items. Cut repeated reading, not explanation review or sleep. |
| 8–10 weeks | Give Domain 2 four weeks instead of three, then add one to three weeks for your miss log and cumulative review to reach eight to ten weeks. Add a cumulative review day every other week. If you have enough additional items, take a second full-length practice two weeks before test day. |
| Working or finishing fieldwork (8–10 hours a week) | Weekdays become 60 minutes: 25 minutes of content, 15 minutes of question work, and 20 minutes of explanation review. Keep the Saturday block and stretch the plan to 9–10 weeks. |
| Retaking | Start from your NBCOT feedback report, not week 1. Put your lowest domain first (see "If you're retaking"). |
30 free NBCOT COTA practice questions
These are original, unofficial practice questions written by Castleport Test Prep. They are not NBCOT questions. Your result here is feedback on these 30 items, not a predicted NBCOT score. Each question is labeled with the 2022 COTA outline domain and task it targets, and the set approximately follows the outline's proportions: 8 Domain 1, 17 Domain 2, and 5 Domain 3 questions. It does not cover every outline task.
Scoring this set: Single-answer questions are worth 1 point. Multi-select questions have six options and three correct answers; select exactly three. Each correct option you select earns 1 point (up to 3), and wrong picks don't subtract, which mirrors NBCOT's published item-credit rule. Total possible: 44.
Choose your answer, then open its explanation. All 30 questions, answers, and sources are included below.
Domain 1: Collaborate and Gather Information (Questions 1–8)
Question 1
A COTA in a skilled nursing facility is working with a client on toileting and lower-body dressing goals. Three weeks into a six-week plan, the client is now dressing and toileting independently and safely. What should the COTA do?
Show answer and explanation
Answer: C. Under AOTA's supervision guidelines, the OTR is responsible for deciding whether to continue, modify, or discontinue occupational therapy services, and the COTA contributes by sharing information and documentation about the client's response. Independently discharging the client (A) or replacing the goals (B) would bypass the OTR's responsibility for the plan. Continuing a plan whose goals are met (D) ignores what the COTA has observed. State practice acts can add stricter rules.
Review next: OTR and COTA roles in evaluation, intervention planning, intervention review, and outcomes.
Question 2
An OTR wants to delegate a standardized assessment to a newly hired COTA. According to AOTA's supervision guidelines, what must be in place before the COTA administers it?
Show answer and explanation
Answer: B. AOTA's guidelines say the COTA who accepts a delegated task is responsible for demonstrating service competence, and that the OTR and COTA demonstrate and document service competence for specific assessments. A specialty credential (A) does not replace demonstrated competence in the delegated assessment. Supervision methods vary with the client, setting, and regulations, so constant on-site presence isn't a universal rule (C), although some states or payers require more. The COTA administers delegated assessments and reports results; the OTR interprets the data and develops the plan (D).
Review next: What the COTA contributes to evaluation and what stays with the OTR.
Question 3
A COTA in early intervention is reviewing developmental milestones with a family. Which skill does CDC list as a 1-year movement milestone?
Show answer and explanation
Answer: A. CDC lists picking things up between the thumb and pointer finger among the movement milestones most children reach by 1 year. CDC places eating with a spoon (B) at 2 years, using a fork (C) at 3 years, and unbuttoning some buttons (D) at 4 years.
Review next: Fine-motor and self-care milestones from 1 to 5 years.
Sources: CDC, Milestones in Action: By 1 Year; CDC, Milestones by 2 Years; CDC, Milestones by 3 Years; CDC, Milestones by 4 Years
Question 4
A client with Parkinson's disease is writing a grocery list during a session. The COTA notices the letters start at a normal size, then get smaller and more crowded as she writes. What should the COTA report to the OTR?
Show answer and explanation
Answer: A. Micrographia is small, cramped handwriting that can get progressively smaller as the person keeps writing. It's characteristic of Parkinson's and often an early symptom. A resting tremor (B) is shaking, a different Parkinson's symptom. Hemianopsia (C) is loss of half the visual field and wouldn't explain shrinking letters.
Review next: Other Parkinson's movement symptoms (bradykinesia, rigidity, postural instability) and the writing strategies that help.
Sources: Parkinson's Foundation, Small Handwriting; Parkinson's Foundation, Tremor; National Library of Medicine, Hemianopsia
Question 5
A COTA is starting a home program with a client who prefers to speak Vietnamese and needs an interpreter to follow the instructions. The client's adult daughter offers to interpret, and her 15-year-old grandson is also in the room. What should the COTA do?
Show answer and explanation
Answer: D. AHRQ's health literacy toolkit lists qualified healthcare interpreters, including telephone and video services, as acceptable language access, and family and friends as unacceptable unless they are qualified interpreters. Using family (A) can make it harder for the client to speak privately and risks the family member's views replacing the client's. If a client insists on family, AHRQ says to respect that but also get a qualified interpreter. The minor grandson should not interpret for this routine home-program instruction (B). Demonstration alone (C) can't confirm the client understands safety instructions.
Review next: Teach-back and other strategies for making health information usable.

Question 6
During an outpatient session, a recently widowed client tells the COTA, "My kids would be better off without me," and mentions he has been giving away his tools. What should the COTA do?
Show answer and explanation
Answer: D. NIMH lists talking about being a burden to others and giving away important items among the warning signs of suicide, and says to get help as soon as possible. Waiting for a meeting (A) or redirecting (B) delays help. A promise of secrecy (C) can't be kept when someone's safety is at risk. Everyone can also call or text the 988 Suicide & Crisis Lifeline.
Review next: Your setting's suicide-risk protocol and how to escalate safety concerns.
Sources: NIMH, Warning Signs of Suicide (revised 2025); NIMH, 5 Action Steps to Help Someone Having Thoughts of Suicide (revised 2024); NIMH, Frequently Asked Questions About Suicide (revised 2023)
Question 7
In the clinic, a client puts together a cold lunch on her own when everything she needs is set out on a table within reach. On a home visit, the COTA sees that her dishes and food are stored on high shelves, and she stops several times to reach for them. What should the COTA report to the OTR?
Show answer and explanation
Answer: B. Activity analysis looks at the task's demands, the client's skills, and the setting together. The 2022 COTA outline lists "demands across contexts or settings" and "the role of performance context" under this task, and AOTA describes evaluation as identifying what supports and what hinders performance. The clinic setup removed the reaching demand, so it didn't test what home requires. A assumes success in one setup carries over to another. C invents a sequencing problem: she completed every step. D blames one body function, and nothing in the stem tells you about her grip. Report what you saw; the OTR interprets it and updates the plan.
Review next: Separating what you observed from what you inferred, and grading task demands such as reach, weight, and number of steps.

Question 8 (select three)
A COTA is writing a one-page home exercise handout for a client with limited health literacy. Which features make the handout easier to read and use? Select the three best.
Show answer and explanation
Correct: B, D, E. AHRQ's guidance for easy-to-understand materials calls for common, everyday words instead of medical terms (B), designs that leave white space and left-justify text (D), and providing only the information people must have (E). AHRQ advises avoiding all caps (A). Shrinking the font just to fit the page (C) can make the handout harder to read. AHRQ recommends whole numbers such as "1 in 10" rather than decimals or percentages (F).
Review next: Teach-back and using pictures or video to demonstrate self-care.
Sources: AHRQ, Health Literacy Universal Precautions Toolkit, Tool 11: Assess, Select, and Create Easy-to-Understand Materials; CDC, Clear Writing: Font and Layout Guidance
Domain 2: Select and Implement Interventions (Questions 9–25)
Question 9
The OTR's plan includes a cold pack before hand exercises for a client with arthritis. The COTA reviews the chart first. Which finding means the cold pack should NOT be used?
Show answer and explanation
Answer: A. In Houghton and colleagues' evidence-based guideline on electrophysical agents, cold hypersensitivity such as Raynaud's phenomenon is a contraindication to cryotherapy. A metal implant (B) is listed as safe for cold. Hypertension (C) is a precaution for cold, not a contraindication. The COTA should report the finding to the OTR. Using physical agent modalities also requires demonstrated competence, and applicable practice requirements must be followed.
Review next: Contraindications and precautions for heat, cold, and electrical stimulation.

Question 10
While helping a client who uses a wheelchair with toileting, the COTA notices a shallow open area over the sacrum. The wound bed is pink, red, and moist, and no fat is visible. How would this pressure injury be staged?
Show answer and explanation
Answer: B. The NPIAP defines a Stage 2 pressure injury as partial-thickness skin loss with exposed dermis, a viable pink or red moist wound bed, and no visible fat. Stage 1 (A) is intact skin with non-blanchable redness. Stage 3 (C) is full-thickness skin loss in which fat is visible. A deep tissue pressure injury (D) can present as persistent non-blanchable deep red, maroon, or purple discoloration or a blood-filled blister. The COTA should report the finding to the OTR and nursing right away.
Review next: Pressure injury prevention: repositioning, seating, and cushions.

Question 11 (select three)
A COTA is teaching joint protection to a client with arthritis in both hands. Which strategies should the COTA teach? Select the three best.
Show answer and explanation
Correct: A, C, F. Joint protection means using larger, stronger joints (A), avoiding gripping objects tightly (C), and reducing effort, for example with a trolley (F). Arthritis UK specifically warns against lifting heavy objects with the wrists bent downward (B) and using too few joints, like a few fingers to carry a plastic bag (D). Pain is a warning sign to rest or pace (E), not something to push through.
Review next: Energy conservation and adaptive equipment for hand arthritis.
Question 12 (select three)
A client with COPD gets short of breath during morning grooming at the bathroom sink. Which energy conservation strategies should the COTA teach? Select the three best.
Show answer and explanation
Correct: A, D, E. Leeds Teaching Hospitals' OT guidance for people with breathlessness recommends gathering items beforehand (A), sitting where possible (D), and resting the elbows on the counter (E). Standing throughout (B) works against the "position" principle. Items should be kept between shoulder and waist height, not up high (C). The guidance says to pace yourself and not rush (F).
Review next: The four Ps (prioritize, plan, pace, position) and pursed-lip breathing.
Question 13
A COTA is teaching a 5-year-old with a developmental disability to put on a T-shirt using backward chaining. How should the COTA set up the first sessions?
Show answer and explanation
Answer: A. In backward chaining, the adult completes all the earlier steps and the learner does only the final step. Once that step is mastered, the learner takes on the second-to-last step, and so on. Teaching the first step first (B) is forward chaining. Practicing every step every session (C) is total task teaching. A single demonstration (D) isn't chaining.
Review next: Graded cueing and how to fade prompts.

Question 14
A client with visual processing difficulties keeps leaving rice and mashed potatoes on his plate because he doesn't see them. Which change should the COTA suggest?
Show answer and explanation
Answer: C. UCSF's Memory and Aging Center recommends solid-color, high-contrast plates and placemats, matching light foods to dark plates and dark foods to light plates. Patterns (A) make items harder to pick out. White on white (B) provides little contrast; a clear glass plate (D) does not by itself provide a contrasting background.
Review next: Lighting, glare control, and contrast in the kitchen and bathroom.
Source: UCSF Memory and Aging Center, Home Safety Tips for People with Visual Dysfunction
Question 15
A COTA is about to help a client who has been assessed as safe for a one-person stand-pivot transfer from bed to wheelchair. What should the COTA do before starting?
Show answer and explanation
Answer: A. MedlinePlus's transfer steps start with parking the wheelchair next to the bed, parallel or at a slight angle, putting the brakes on, and moving the footrests out of the way. During the turn, the client may hold onto the helper or reach for the wheelchair, but should not wrap her arms around the helper's head or neck (B). Unlocked brakes (C) let the chair roll. The chair needs to be close to the bed (D).
Review next: Gait belts, body mechanics, and what to do if a client starts to fall.
Source: MedlinePlus, Moving a patient from bed to a wheelchair (reviewed October 2025)
Question 16 (select three)
A COTA is coaching a daughter who bathes her father, who has moderate dementia and resists bathing. Which strategies should the COTA recommend? Select the three best.
Show answer and explanation
Correct: B, C, F. The Alzheimer's Association recommends preparing the bathroom in advance (B), giving the person choices (C), and using simple phrases to coach each step (F). It advises always checking the water temperature yourself, because the person may not sense dangerously hot water (A). Bathing at a different time than he's used to (D) can be confusing. It suggests starting with 2 to 3 inches of water (E).
Review next: Dressing and grooming strategies across the stages of dementia.
Source: Alzheimer's Association, Bathing
Question 17
A client's scar is hypersensitive two months after hand surgery. The OTR's plan includes a texture desensitization program. How should the COTA teach the client to progress it?
Show answer and explanation
Answer: D. Desensitization begins with light rubbing using a soft texture, often starting at the edge of the sensitive area and working toward the most sensitive part, then gradually moving to rougher textures and more pressure as tolerated. Starting with the roughest texture (A) skips the gradual progression. Without treatment, the brain can keep interpreting touch as pain, so avoidance (B) works against recovery. Comparing with the unaffected side is helpful, but the affected area is what needs the program (C).
Review next: Scar massage, tapping, and edema control after hand surgery.
Question 18
A client's hand is swollen after a wrist fracture. The OTR's plan includes edema management with active finger movement cleared by the treating team. What should the COTA teach the client to do at home?
Show answer and explanation
Answer: A. Hand therapy guidance recommends elevating the hand above heart level so gravity drains the swelling, and repeatedly straightening the fingers and making a fist to create a pumping action. A hanging arm (B) lets fluid collect in the hand. Keeping the fingers still (C) loses the pumping effect. A tight band (D) can restrict circulation.
Review next: Retrograde massage and compression, including when not to use them.
Question 19
A client with a weak right leg is learning to walk with a single-point cane. Which hand should she hold it in?
Show answer and explanation
Answer: B. The cane goes in the hand opposite the weaker leg. She moves the cane forward at the same time as her weaker right leg, then steps past it with her stronger left leg. Holding it on the same side as the weak leg (A) does not follow this recommended technique. Hand dominance (C) isn't the rule.
Review next: Curbs and stairs with a cane: "up with the good, down with the bad."
Question 20
A client with carpal tunnel syndrome asks the COTA why the OTR recommended a wrist orthosis and when to wear it. Which explanation is correct?
Show answer and explanation
Answer: C. AAOS explains that a brace or splint worn at night keeps the wrist from bending during sleep, and that a straight or neutral wrist position reduces pressure on the nerve in the carpal tunnel. It may also help to wear it during activities that aggravate symptoms. AAOS notes that holding the wrist bent forward or backward for long periods increases pressure on the nerve, so A and D are wrong. Taking it off at night (B) defeats its purpose, since many people sleep with bent wrists.
Review next: Checking orthosis fit and skin, and teaching wearing schedules.
Source: AAOS OrthoInfo, Carpal Tunnel Syndrome, "Bracing or splinting"
Question 21
A client with a below-knee amputation finds a small open area on his residual limb where the prosthetic socket rubs. What should the COTA advise?
Show answer and explanation
Answer: D. The Amputee Coalition advises not using the prosthesis when there is skin breakdown, applying a clean dressing daily, and seeing the doctor or prosthetist. It specifically warns against padding a pressure area (A), because padding adds pressure, and against talcum powder (B), which can ball up and cause abrasion. A red spot that becomes an ulcer can mean weeks without the prosthesis, so continuing (C) risks a bigger problem.
Review next: Daily residual limb care: washing, twice-daily skin checks with a mirror, and sock or liner care.
Question 22 (select three)
A COTA is completing a home safety visit with an older adult who fell last month. Which recommendations should the COTA make? Select the three best.
Show answer and explanation
Correct: A, B, E. CDC's STEADI home checklist recommends removing or securing throw rugs (A), adding nightlights along the bed-to-bathroom path (B), and installing grab bars inside and next to the tub and next to the toilet (E). It advises keeping things you use often on lower shelves, about waist high (C), never using a chair as a step stool (D), and coiling or taping cords next to the wall (F).
Review next: Lighting at stairs, handrails on both sides, and non-slip tub surfaces.
Source: CDC STEADI, Check for Safety: A Home Fall Prevention Checklist for Older Adults
Question 23
A client's front entrance is 24 inches above the walkway. The family wants a ramp that meets the 2010 ADA Standards' maximum running slope of 1:12. What is the minimum horizontal length of the ramp run?
Show answer and explanation
Answer: C. A 1:12 slope means at least 12 inches of run for every inch of rise: 24 inches × 12 = 288 inches, which is 24 feet. This is the horizontal sloping run, excluding the required landings. A single run can rise up to 30 inches, so the 24-inch rise alone does not require an intermediate landing in a straight run; level landings are still required at the top and bottom, and a change of direction requires a landing. Because the rise is greater than 6 inches, the ramp also needs handrails on both sides. 2 feet (A) confuses rise with run. 12 feet (B) would fit only a 12-inch rise. 30 feet (D) is the run for the maximum 30-inch rise.
Review next: Ramp width, landings, and edge protection.
Question 24
A client recovering from a stroke has swallowing difficulty and has been assessed and cleared for oral intake. The team's plan includes mealtime positioning. Which positioning should the COTA reinforce?
Show answer and explanation
Answer: A. MedlinePlus advises people with swallowing problems to sit up as straight as possible when they eat and to sit upright for 30 to 45 minutes after eating. Reclining (B) or lying down right after the meal (C) works against that guidance. Eating should be relaxed and focused, not combined with walking (D). Follow the team's prescribed food textures, liquid thickness, and any individualized swallowing instructions.
Review next: Adaptive utensils and setup for one-handed eating.
Sources: MedlinePlus, Swallowing problems (reviewed April 2026); ASHA Practice Portal, Adult Dysphagia, Treatment Options and Techniques
Question 25
A medically stable client with COPD has her usual shortness of breath when climbing the stairs to her bedroom. Her established therapy plan includes breathing training. Which breathing technique should the COTA teach her to use during this activity?
Show answer and explanation
Answer: C. Pursed-lip breathing slows the pace of breathing and is meant for activities such as climbing stairs, bending, and lifting. MedlinePlus describes breathing in through the nose for about 2 counts and out through pursed lips for 4 or more counts. It says not to hold your breath (A) or force the air out (B). Quick, shallow breathing (D) is what the technique replaces.
Review next: Pacing and rest breaks on stairs, and where to place a chair for resting.
Source: MedlinePlus, How to breathe when you are short of breath (reviewed January 2026)
Domain 3: Uphold Professional Standards and Responsibilities (Questions 26–30)
Question 26
A COTA is scheduled for a short session with an inpatient who has suspected C. diff infection. What does the COTA need to do?
Show answer and explanation
Answer: D. CDC tells clinicians to wear gloves and a gown when treating patients with potential infectious diarrhea, including C. diff, even during short visits. Gloves matter because hand sanitizer doesn't kill C. diff spores. Gloves do not replace hand hygiene; clean your hands after removing them and follow the facility's infection-control procedure. Gloves alone (A) or no protective equipment (C) don't meet that guidance. An N95 (B) is for airborne precautions; C. diff spreads by contact with contaminated hands, surfaces, and equipment. Equipment that touched the client needs cleaning with an EPA-registered disinfectant that kills C. diff spores.
Review next: Standard, contact, droplet, and airborne precautions.
Sources: CDC, C. diff: Facts for Clinicians (updated April 2026); CDC, Clinical Safety: Hand Hygiene for Healthcare Workers (February 2024)
Question 27 (select three)
During a group session, a client falls to the floor and begins shaking and jerking. What should the COTA do? Select the three best.
Show answer and explanation
Correct: B, C, E. CDC's seizure first aid steps include turning the person gently onto one side to keep the airway clear (B), putting something soft under the head and clearing the area (C), and timing the seizure, with 911 or immediate medical help if it lasts more than 5 minutes (E). Do not wait five minutes for a first seizure, another seizure soon afterward, injury, or trouble breathing or waking; CDC also lists a seizure in water, pregnancy, and diabetes with loss of consciousness as reasons to call 911. CDC says not to hold the person down (A), not to put anything in the mouth (D), and not to offer food or water until the person is fully alert (F). Follow your facility's emergency procedure as well.
Review next: When to call 911 after a seizure, and other emergencies such as hypoglycemia.
Source: CDC, First Aid for Seizures
Question 28 (select three)
During an outpatient session, which sudden changes in a client should make the COTA call 911 or activate the facility's emergency response right away? Select the three best.
Show answer and explanation
Correct: A, D, F. The American Stroke Association's B.E. F.A.S.T. warning signs include face drooping (A), arm weakness (D), and speech difficulty (F), and the T means time to call 911 immediately. The mnemonic also includes sudden balance loss and eye or vision changes. It also says to note when symptoms first appeared. B, C, and E, as described in this question, do not establish those sudden neurological changes.
Review next: Other sudden stroke symptoms (vision loss, severe headache, loss of balance) and TIA.
Question 29
A client tells the COTA, "You can put my progress photo on your Instagram." The COTA wants to share it. What should she do?
Show answer and explanation
Answer: C. Principle 8 of NBCOT's Code of Conduct says certificants shall not post anything that may reveal a client's identity or therapeutic relationship, including photos, without the client's written consent, and notes that any statement about a client can contain enough information for someone to recognize them. Verbal permission (A) doesn't meet that standard. Blurring a face (B) or a private account (D) doesn't remove the requirement. Employer policies and HIPAA can add further limits.
Review next: The other NBCOT Code principles, including exam confidentiality.
Source: NBCOT Certification Exam Handbook, Candidate/Certificant Code of Conduct, Principle 8 (p. 9)
Question 30
A COTA is helping the OTR find evidence for a fall-prevention group. For a question about whether an intervention works, and assuming comparable quality and applicability, which option ranks highest in the Oxford Centre for Evidence-Based Medicine's 2011 levels of evidence?
Show answer and explanation
Answer: C. In the Oxford 2011 table for treatment benefits, a systematic review of randomized trials is Level 1. A nonrandomized controlled cohort study (D) is Level 3, a case series (A) is Level 4, and mechanism-based reasoning (B) is Level 5. Study design is a starting point: the table allows evidence to be graded down for problems such as poor quality, imprecision, indirectness, or inconsistent results, and up for a large effect. Check the quality and relevance of the evidence before applying it to a client.
Review next: Writing a focused PICO question and judging whether a study fits your client.
After you finish: add up your points out of 44 and log every miss by domain and by cause. Don't overread a 30-question sample. It approximately follows the outline's domain shares, but it's far too small to measure readiness. Use it to choose what to review next.
How the six-option multi-select items work
The COTA exam mixes single-answer questions with stand-alone multi-select items. Here's what NBCOT says about them:
- Each multi-select item has a question stem and six options. Three are correct and three are incorrect. You must select three.
- You earn credit for each correct option you select, and incorrect selections aren't deducted.
- On the COTA exam they stand alone. The opening-scene "scenario sets" belong to the OTR exam.
- If time runs out, flagged items with no option selected get no credit.
Sources: NBCOT Certification Exam Handbook, pp. 23–24; NBCOT, Foundations of the NBCOT Exams.
How we'd approach them (our strategy, not NBCOT's):
- Find the client, the goal, and the limit. Underline the diagnosis, the setting, any precaution, and what the question asks you to achieve. Most wrong options break one of these.
- Judge each option on its own. Because credit comes per correct option, ask "Is this one right for this client?" six times instead of hunting for a pattern.
- Check the COTA's role. An option that has the COTA independently interpreting the evaluation, establishing new goals, or making the discharge decision bypasses the OTR's responsibility. Collaboration on goals and reporting progress are part of the COTA's role.
- Pick your three clearest first. When you're torn between options, choose the one that's safe and fits the client's goal and stage of care.
- Select exactly three before moving on. Check that all three choices are marked.
- Try the format before test day. NBCOT's free multi-select sample items show the layout. NBCOT notes they don't replicate the exam-day experience.
How to review a missed question
Most wasted study time comes from treating every miss the same way. Before you look anything up, decide why you missed it.
| Cause | What it looks like | What to do next |
|---|---|---|
| Knowledge gap | You didn't know the fact, precaution, milestone, or technique | Learn it, then answer two new questions on it within a few days |
| Role gap | You picked something the OTR decides, not the COTA | Rewrite the question as "What does the COTA do here?" and note the boundary |
| Cue-reading gap | You missed a deciding detail: the setting, a precaution, "FIRST," "NOT," "MOST" | Before reading the options, underline the detail that decides the question |
| Assumption gap | You added a fact the stem didn't give, like a diagnosis, a deficit, or a cause | Circle what the stem actually says, and cross out any option that needs an extra fact to be right |
| Pacing or second-guessing | You rushed, ran long, or changed a supported answer without a reason | Do timed blocks at about 76 seconds per item; change an answer only when you can name the fact that changed your mind |
Worked example: Question 1. Say you chose B, "Write new goals for meal preparation."
- If you didn't know who decides whether services continue or change, that's a role gap. Review AOTA's supervision guidelines, then try a new question about discharge or plan changes.
- If you knew the rule but focused on "the client is doing well, so add something new," that's a cue-reading gap: the deciding detail was that the goals were met. The fix is slowing down on what changed, not more reading.
Same wrong answer, two different fixes.
Your miss log. Copy this into a notebook or spreadsheet and add a row for every miss and every lucky guess:
| Question | My answer and why | Deciding detail I missed | Cause | Rule to remember (and source) | Retry date and result |
|---|---|---|---|---|---|
| COTA-001 | B; the client was doing well, so I added a new goal | Her goals were met; the OTR decides what happens next | Cue-reading gap | COTA reports progress; OTR decides to continue, modify, or discontinue (AOTA supervision guidelines) | Day 3: explained it correctly before checking |
Two habits make the log work. First, write the correction in your own words before rereading the explanation. Second, come back to the question a few days later and explain why each wrong option fails, not just which letter is right. Recognizing an answer you've already seen isn't the same as solving a new case, so pair each retry with at least one new question on the same rule.
How the NBCOT COTA exam works
| Exam feature | NBCOT COTA |
|---|---|
| Exam owner | National Board for Certification in Occupational Therapy (NBCOT) |

Pacing. 240 minutes for 190 items is about 76 seconds per item, or roughly 47 to 48 items an hour. Rough checkpoints: item 48 at one hour, item 95 at two hours, item 143 at three hours. That's an average, not a per-question timer. Allow extra time for items that need it, and bank time on shorter questions. Breaks come out of your four hours. The optional tutorial at the start doesn't. Reopening the tutorial or Help during the exam does use exam time (NBCOT, Take Your Exam).
What 450 means. It's a scaled score, not a percentage, so 450 doesn't mean "75% correct," and NBCOT doesn't publish a raw number you need. Each version of the exam has different items, so NBCOT converts the number you answered correctly to a 300–600 scale and statistically equates versions so 450 means the same standard on every form. The pass decision is based on the whole exam. If you don't pass, your feedback report shows your performance by domain, which NBCOT says is for diagnostic purposes only.
Getting to test day. You apply online through MyNBCOT; the application is valid for 90 days. Your school sends an official final transcript. If all degree and graduation requirements are complete but the final transcript is not yet available, your program may allow a Degree Verification Form. It must meet NBCOT's timing rules: within six months of your anticipated graduation date and in that same calendar year. Results remain on hold until NBCOT receives and approves the final transcript. Once NBCOT approves your application, you receive an Authorization to Test (ATT) letter within three business days, and the ATT is active for 90 days; test within the dates printed on it. If you want your result on a specific scoring date, test at least three days before it. Rescheduling or cancelling less than 48 hours ahead, missing the appointment, or being unable to test because you arrived more than 15 minutes late or lacked proper ID requires a $115 ATT reissue while your application remains active. An expired application requires a new application and its fee. These timing and document rules come from the NBCOT handbook, pp. 11 and 15–21. For the full process, see how to apply for the NBCOT exam and when NBCOT releases scores.
What changed in 2024. Since January 2, 2024, every COTA exam has been built from the 2022 COTA content outline, with the current domain names and the 27/55/18 split, and exams have been delivered by Pearson instead of Prometric. The COTA item types didn't change. Older guides that describe 200 questions or Prometric scheduling are out of date (NBCOT 2024 Exam FAQs).
Free official tools to use
- 2022 COTA Examination Content Outline. Read it once in week 1 and use its task and knowledge statements as your checklist.
- NBCOT Certification Exam Handbook. NBCOT requires you to read it before applying.
- Find NBCOT's COTA exam tutorial and multi-select sample items. Go through both before test day so the screen, highlighting, strike-out, and flagging aren't new.
- NBCOT's COTA reference list. The Foundations page lists textbooks NBCOT may use to check the accuracy of COTA items. NBCOT says items aren't written from textbooks and that using these books doesn't guarantee a passing score.
Your final week
- Mixed review and your miss log only. Don't start a new textbook.
- Finish any last full practice early in the week, with time left to review it.
- Revisit this page's seven multi-select items and rehearse your pacing checkpoints. If you have additional unseen items, include those too.
- Walk through NBCOT's COTA exam tutorial once.
- Check your ATT letter dates, your Pearson location, and travel time. Plan to arrive 30 minutes early.
- Bring two acceptable original forms of ID, and make sure the first and last names match your ATT letter exactly. Follow the NBCOT ID requirements for the required photo, signature, and validity.
- Know that you'll have seven minutes to accept the acknowledgment screen before the exam starts. If you don't, the appointment is forfeited.
- Protect your sleep. Don't try to memorize low-frequency facts in the last 48 hours.

If you're retaking
Don't repeat the same study plan. Start with your data.
- Read your feedback report. It shows your overall score, your performance by domain, and the average score of new graduates who recently passed. Use the domain chart to choose where to start, keeping in mind NBCOT intends domain information for diagnosis only.
- Sort your practice misses by cause. Someone with mostly role and cue-reading misses needs a different plan than someone with knowledge gaps.
- Move your hours. Put your lowest domain into the first weeks and keep mixed practice going, with multi-select items in every block.
- Know the waiting period. Attempts 2, 3, and 4 can be taken 30 days after your last exam; attempts 5, 6, and 7 after 60 days; attempt 8 and later after 90 days. You can reapply 30 days before your next eligible date, and every retake needs a new application. See Retaking the Exam in the NBCOT handbook, p. 33.

Quick answers
How long should I study for the NBCOT COTA? NBCOT doesn't set a study length. The plan above runs six weeks at about 11–15 hours a week. Stretch it to 8–10 weeks if you're working or your first timed practice shows big gaps in Domain 2.
How many questions are on the COTA exam? 190, in four hours. Some are unscored field-test items, and NBCOT doesn't say how many or which ones.
Is the COTA exam the same as the OTR exam? No. The OTR exam has 180 items, four domains, and multi-select scenario sets with an opening scene. The COTA exam has 190 items, three domains, and stand-alone multi-select items. Make sure every resource you use is built for the COTA. (Taking the OTR instead? Use the OTR exam content outline.)
Do I get partial credit on multi-select questions? Yes. NBCOT gives credit for each correct option you select and doesn't deduct for incorrect ones.
What happens if I fail? You get a feedback report with domain-level performance and must submit a new application to retest. Attempts 2–4 require at least 30 days after the last exam, and you may reapply 30 days before your next eligible exam date. See "If you're retaking."
Does passing the NBCOT make me licensed? No. NBCOT certification is separate from state licensure, and sending your score to a state board doesn't start a license application. All 50 states, DC, Puerto Rico, and Guam require NBCOT initial certification as part of OT regulation, but each has its own steps. Use NBCOT's Find Your State Board's Info page.
Can a COTA take the OTR exam later? Yes, after earning a qualifying OT degree. NBCOT's handbook tells COTAs who become eligible for the OTR exam to log in to their existing MyNBCOT account and add the OT degree to their profile before applying.
