CMSRN Exam Prep: The 89-Right 2026 Study Plan and Free Tool

Last verified: August 28, 2026 · By the Castleport Test Prep Editorial Team

The CMSRN exam is 150 questions in three hours. Only 125 count toward your score. MSNCB publishes a passing standard score of 95, described as about 71% correct—so about 89 of 125 right is a useful planning number, leaving about 36 misses. It is not an official fixed raw cut score. The application fee is $394, or $267 for AMSN members.

That is the answer most CMSRN exam prep pages stop at. Here is the part they skip, and it is the blind spot that can wreck an otherwise solid plan: 66 of the 125 scored-item allocation sits in systems, team, coordination, documentation, ethics, quality, and professional-practice domains—not the Patient/Care Management or Holistic Patient Care domains.

We counted every numbered activity line in the current blueprint. Then we built the free tool around the parts a candidate actually has to decide.

The free CMSRN 89 Check belongs directly above this paragraph.

Six tabs, no email, nothing to buy. Put in your test date, weekly study hours, and weakest domains. It builds a weekly allocation from the current five-domain blueprint, converts “standard score 95” into a visible planning band, prices the routes that can be priced from published fees, checks whether the material in your hand matches the active exam, and gives you a 72-second pacing drill.

Castleport independently verifies exam-version and requirement details against current official sources, shows its math, and dates the check.

This page is for you if—and is not if

It is for you if you are an RN preparing for the CMSRN and want to know what to study, what it costs, whether you qualify, what version is active, and whether the review material someone handed you still matches it.

It is not for you if:

• You are studying for ANCC’s MEDSURG-BC exam. Different credentialing body, different blueprint, different eligibility details. We compare the published structures below, but you should never use one exam’s numbers as the other exam’s rules.
• Your hours come only from pediatrics, psychiatry, obstetrics and gynecology, the operating room, or the emergency room. MSNCB lists those as settings that are not medical-surgical. Read the eligibility section before paying.
• You already hold the CMSRN and only need to renew. Renewal has a separate January 2026 handbook and current web page. Skip to the recertification section.
• You want real, recalled, leaked, or “latest live” exam questions. Castleport does not use them or point candidates toward them.
• You want a pass guarantee. Castleport does not offer or imply one.

The one thing to know before you spend a dollar on CMSRN exam prep

The right prep path turns on five things: the blueprint active on your test date, whether your practice hours qualify, the time left in your 90-day authorization window, the domains you actually neglect, and whether the product in your hand maps to all five domains.

The official handbook and MSNCB’s current site set the requirements. The free CMSRN 89 Check turns those published facts into a plan. It does not diagnose readiness, estimate your eventual score, or predict whether you will pass.

---

What score do you actually need to pass the CMSRN?

MSNCB requires a standard score of 95 and describes it as approximately 71% correct. Across 125 scored questions, 71% is 88.75, so about 89 right—and about 36 misses—is a planning translation, not an official fixed raw cut score.

A standard score is converted from your raw performance so candidates taking different forms can be held to a common standard. That is why MSNCB publishes 95, not “89 out of 125.”

But you cannot plan study work around an abstract converted score. You can plan around a band:

Aim past the band, not at it. A plan built around exactly 89 leaves no cushion for a weaker domain, a difficult form, or a bad testing morning.

Twenty-five of the 150 questions are unscored pretest items. You cannot identify them, so they still consume time. At the full-exam average of 72 seconds per question, 25 items represent about 30 minutes of the three-hour clock.

Official structure and score language: MSNCB CMSRN Certification and the current CMSRN Certification Handbook, last updated July 2025. The 89/36 translation is Castleport’s arithmetic on MSNCB’s approximate percentage.

→ Open “The 89 Map” in the tool and see the planning band square by square.

Where does the CMSRN actually keep its points?

The current blueprint allocates 59 scored items to Patient/Care Management plus Holistic Patient Care and 66 to the other three domains. That 59/66 grouping is Castleport’s planning classification, not MSNCB’s terminology.

The official domain weights are:

Read the second row again. Nursing Teamwork and Collaboration is the second-largest domain. It includes delegation, supervision, mentoring, preceptorship, leadership models, change management, staffing, conflict, financial stewardship, and disaster planning.

Now group the five domains by the type of work they publish:

• Patient-facing care domains—Patient/Care Management + Holistic Patient Care = 59 items, 47.2%
• Systems, interprofessional, professional, and team domains—Elements of Interprofessional Care + Professional Concepts + Nursing Teamwork and Collaboration = 66 items, 52.8%

Those category names are ours. The item counts are MSNCB’s.

A grouping-free version makes the same point: Professional Concepts plus Nursing Teamwork and Collaboration equals 45 scored items, or 36% of the exam. Those two domains do not define body-system categories. A plan organized only around cardiovascular, respiratory, gastrointestinal, renal, neurological, and endocrine content can be useful clinical review while still failing to map a large part of the published exam.

Which domains carry the most published topic load per point?

We counted each numbered activity line in the 2023 CMSRN Exam Blueprint. The count returned 132 activity lines across 28 subareas. We completed the count twice; both passes returned the same 132 and the same domain split.

This ratio does not measure question difficulty or tell you how many questions will be drawn from each individual line. It measures how much published blueprint territory sits behind each allocated scored item.

The spread is about 2.03×: Professional Concepts publishes roughly twice as many activity lines per allocated point as Patient/Care Management. A plan allocated only by domain size can therefore under-serve the domain with the densest published territory.

Two blocks deserve an explicit place in the plan:

• Leadership has 12 numbered lines inside Nursing Teamwork and Collaboration. It is the single largest named block in the blueprint and an easy block to skim.
• Care Coordination and Transition Management has 11 numbered lines inside Elements of Interprofessional Care. It covers discharge planning, readmission risk, social determinants, medication reconciliation, and the continuum of care.

The official item counts and percentages are MSNCB’s. The 132-line count, the ratios, and the 59/66 grouping are Castleport’s original analysis.

→ Open “Where the Points Are,” then carry that load map into the Study Plan tab.

---

How do you build a CMSRN study plan that matches the blueprint?

Start from MSNCB’s weights, then bend the allocation toward your two weakest domains. Do not divide your study time evenly just because the blueprint has five columns.

Here is the method used in the tool:

1. Start with the official weight. Patient/Care Management 32, Teamwork 21, Interprofessional Care 17, Holistic Patient Care 15, Professional Concepts 15.
2. Apply a self-rating factor. Weak = 1.35, developing = 1.00, strong = 0.75.
3. Normalize the adjusted weights. Divide each adjusted domain value by the adjusted total.
4. Multiply by your weekly hours. The result is a study-time allocation, not a readiness result.

A worked eight-hour example for a nurse who is strong in Patient/Care Management and weak in Professional Concepts and Teamwork:

The nurse who is already strong at the bedside stops automatically spending 32% of study time there and starts spending 46.5% on the two weak domains—without abandoning the largest domain.

This is a planning allocation, not a diagnostic, score estimate, or outcome prediction. MSNCB does not publish a required study period. It does publish a hard operational clock: once your Authorization to Test arrives, you generally have 90 days to sit the exam. Build backward from the actual authorization dates in your portal.

→ Put your test date, weekly hours, and five honest self-ratings into the Study Plan tab.

Is the CMSRN hard? What the pass rates actually say

MSNCB published a 67% pass rate for 2025: 4,845 attempts, 3,246 passes, and 1,599 failures. The published rate declined in each published year from 75% in 2021 to 67% in 2025. MSNCB does not publish a first-time-only rate.

The 2024 qualification matters. MSNCB’s live table duplicates 4,337 in both the tested and passed cells while also listing 1,356 failed and a 69% pass rate. Those values cannot all be true. Subtracting failures from tested gives 2,981, and 2,981 ÷ 4,337 = 68.73%, which rounds to MSNCB’s published 69%.

Across 2021–2025, MSNCB reports 19,047 attempts and 5,551 failures, a pooled failure share of about 29.1%. That still does not give any individual candidate a personal probability of passing.

What the trend does not tell you

The current blueprint took effect May 15, 2023, and the pass rate is lower in the later published years. That timing is not proof that the blueprint caused the decline. MSNCB does not publish the causal explanation, first-attempt rates, candidate mix, or form-level difficulty data.

What you can control is how you prepare.

Official figures: MSNCB Statistics. The 2024 implied pass count and pooled calculations are Castleport’s arithmetic and are labeled as such.

---

Do you qualify to take the CMSRN?

For US, territorial, and Canadian candidates, MSNCB lists two main requirements: a current, unencumbered RN license and 2,000 hours of medical-surgical practice in the past three years. Two full years of practice is recommended, not listed as a separate eligibility requirement.

Getting this wrong can cost months or an application fee.

2,000 hours is roughly fifty 40-hour weeks. Do not assume your calendar alone settles eligibility; check the hours and the type of work.

What can count as medical-surgical practice?

MSNCB says medical-surgical nursing is what you practice, not where, and names hospital, outpatient, home, telemedicine, and other nontraditional settings. The current requirement expressly allows practice as a clinical nurse, manager, or educator.

Managers and educators may mistakenly assume their hours do not count, but the current official language says qualifying hours in those roles can count.

If you practice internationally, get the hours requirement in writing

MSNCB’s current public materials conflict for candidates practicing internationally without a US RN license:

• The current certification web page states 1,000 practice hours in the past three years.
• The July 2025 handbook states 2,000 practice hours in the past three years.

Both require a current, unrestricted license and a credential evaluation such as CGFNS or WES where applicable. A candidate in the 1,000–1,999-hour range should obtain written confirmation from MSNCB before paying.

The application audit

The current handbook says MSNCB randomly audits 5% of initial applications. If selected, be ready for the listed supervisor to verify the license and practice hours, and respond within the stated deadline. Name someone who will answer the request and use an email address you actually monitor.

→ Use “Cost & Eligibility” for a rules-based precheck, then treat MSNCB—not the tool—as the final authority.

---

Is your CMSRN study guide out of date?

The active five-domain blueprint took effect May 15, 2023. Pearson VUE and OnVUE now deliver the exam. A current-looking cover can still sit on top of superseded vendor, fee, score, or eligibility language.

The 15-signal CMSRN version check

Signal 4 is deliberately more precise than “body systems are old.” Clinical system review can still be useful. The failure is never mapping that review back to all five current domains, especially Professional Concepts, Interprofessional Care, and Teamwork and Collaboration.

What changed between the April 2024 handbook and the current record?

An old official PDF can still be an old PDF. Check the cover date, then check current web processes for fees and vendor logistics.

→ Run the Version Check on the book, app, or course you were about to use.

What does the CMSRN cost in 2026?

The exam costs $394. AMSN members pay $267. The application contains a $90 nonrefundable processing portion. A first retake is $315, or $189 for AMSN members. A one-year full AMSN membership costs $115, so joining first makes the initial exam route $382—$12 less than paying the standard exam fee alone.

Current published fees

Common routes, priced

Should you join AMSN before applying?

On the initial fee alone, the arithmetic is unusually clean:

• Standard exam: $394
• One-year full membership + member exam: $115 + $267 = $382
• Difference: $12 less, plus the membership term

AMSN also lists a $99 two-year New to Practice membership for a newly graduated nurse or one in practice two years or less. Confirm your eligibility with AMSN before selecting that tier.

The CMSRN Certification Grant can cover the full application fee. MSNCB says applicants must have been AMSN members for at least one year, and applications are open year-round.

Is CertAssure worth buying?

CertAssure is an optional, nonrefundable add-on that covers a second attempt if the first attempt is unsuccessful. It does not predict, guarantee, or improve an outcome.

If—and only if—you apply the published 2025 all-attempt failure rate of 33% as a simple comparison:

• Member expected retake cost: 0.33 × $189 = $62.37, making CertAssure $37.63 more than that expected value.
• Nonmember expected retake cost: 0.33 × $315 = $103.95, making CertAssure $96.05 more than that expected value.

MSNCB does not publish a first-attempt-only rate, so the population rate cannot tell you whether CertAssure fits your own risk. Buy it for budget certainty, not because a cohort average proves it will save money.

If your employer pays: FailSafe, decoded

Every bundle prices each voucher at exactly $394. The value is the second attempt within the program terms, not a lower first-attempt voucher price.

One official conflict is worth taking to the contract: the current FailSafe page says 15% for all tiers, while the July 2025 handbook describes 5% / 10% / 15% for 3 / 5 / 10 vouchers. A facility should confirm the current discount term before an educator negotiates or budgets around it.

Our damaging admission, and what we do instead

We do not currently sell a CMSRN study guide, question bank, course, or paid Exam System. No CMSRN diagnostic is live. This page and the CMSRN 89 Check are new free coverage. Castleport takes no affiliate commission on the AMSN or MSNCB resources named here.

If you need a clinically reviewed question bank today, Castleport is not that product. AMSN’s 150-question practice exam is linked by MSNCB and matches the published CMSRN envelope of 150 questions in three hours. Read its access and contact-hour terms below.

What Castleport did here instead is the work most summaries skip: the 89-right planning translation, a reproducible 132-line blueprint count, a topic-load comparison, a current version map, a five-year statistics check, and the break-even math on the add-on.

→ Price the route that actually applies to you in “Cost & Eligibility.”

What do the current AMSN CMSRN study materials include?

AMSN sells the practice exam and review course MSNCB links. MSNCB also says those resources are not required, are not the only or preferred route, do not include current exam questions, and do not imply successful performance.

AMSN CMSRN Practice Exam—$99 member / $139 nonmember

The live listing states:

• 150 multiple-choice questions
• Three hours per attempt
• Current-blueprint alignment
• Unlimited attempts during access
• Rationales after attempts
• 180-day access from purchase
• 3.0 contact hours claimable once
• “Passing grade of 120.00” plus evaluation for the activity certificate
• No guarantee of passing the CMSRN exam

The listing does not define the denominator or scoring scale behind “120.00,” so it should not be converted into an assumed 80% exam benchmark. It is the activity’s completion threshold, not MSNCB’s CMSRN passing standard.

The current online Certification Review Course—$149 member / $199 nonmember

New buyers are directed to AMSN’s new listing. The live AMSN exam-prep page says:

• 11 newly revised modules
• 14.75 NCPD contact hours
• $149 for members / $199 for nonmembers

The library listing visibly contains 11 numbered lessons, but its description still says nine modules. The older 20.5-hour course is marked for sunset and directs new users to the new course. MSNCB’s resource summary has also continued to surface legacy course language in places.

The current visible lesson list includes one named Teamwork and Collaboration lesson, then clinical/system lessons. It does not show standalone lesson titles named Professional Concepts or Elements of Interprofessional Care. That is not proof those domains are absent inside the modules. It is a buying question:

How do the 11 visible lessons map to all five CMSRN domains, especially Professional Concepts and Elements of Interprofessional Care?

Ask AMSN before buying if the answer affects what you must supplement.

The exam reference list gives away the intended balance

The current handbook says every exam item must cite at least two references, prefers the most recent AMSN Core Curriculum for Medical-Surgical Nursing where possible, and also points to AMSN’s current Scope and Standards of Medical-Surgical Nursing Practice.

The remaining list includes clinical texts, pharmacology, pathophysiology, transcultural nursing, fundamentals, and two leadership/management texts. That is consistent with a blueprint allocating 45 scored items to Professional Concepts plus Nursing Teamwork and Collaboration. It does not mean all 45 items come from those two books; it means leadership and management are explicitly part of the reference architecture.

What happens on CMSRN exam day?

CMSRN delivery is through Pearson VUE at a test center or through OnVUE remote proctoring. The exam is 150 questions in three hours. Test-center candidates receive an immediate printed pass/fail result, and both delivery modes receive detailed online result information within 24 hours.

The 72-second clock

150 questions ÷ 180 minutes = 72 seconds per question.

The Pace Check supplied with this page tests only whether you can maintain the 72-second average timing; it contains no clinical exam items and makes no readiness claim.

Booking, moving, and missing the appointment

“No fee published” is not the same as a guarantee that every mistake is free. MSNCB warns that failing to complete and confirm a reschedule can create a no-show and additional charge. Keep the confirmation email.

The ID rule

Plan on a government-issued photo ID with a signature, matching name, and future expiration date.

The July 2025 handbook says an ID must be unexpired or accompanied by renewal paperwork. The current web page says the ID must be unexpired and that any exception must be preapproved by MSNCB at least 10 business days before the appointment. Do not arrive expecting the testing vendor to interpret that conflict at the door.

→ Run the 72-second Pace Check before test day. It tests the clock, not clinical knowledge.

---

What happens if you do not pass the CMSRN?

MSNCB states that it has no waiting period. You may register for the discounted first retake when ready, within the program’s one-year window. The retake is $315 standard or $189 for AMSN members. After that retake, a new application is required for another attempt.

Practical order of operations:

1. Check whether the problem was a failed attempt, a missed appointment, or an expired authorization.
2. For a missed appointment or expired authorization, ask about the $90 extension within 10 days before defaulting to a higher-priced retake or new application.
3. Use the result information you receive to rebuild the study allocation toward the domains that need work.
4. Do not turn one result into a permanent verdict about your nursing ability.

CMSRN or MEDSURG-BC—which med-surg certification should you take?

Both current exams publish 150 total questions, 125 scored questions, and a three-hour time limit. The deciding differences are eligibility, testing window, administrator, scoring system, and published blueprint emphasis.

A nurse who wants to apply now but has not completed 30 hours of recent med-surg CE may meet CMSRN’s published eligibility and not yet meet MEDSURG-BC’s.

The current blueprints publish different emphasis

ANCC’s current content outline, updated June 30, 2026 while retaining an effective date of September 10, 2024, allocates:

• Assessment and Diagnosis: 49 items / 39%
• Planning, Implementation, and Evaluation: 50 items / 40%
• Professional Role: 26 items / 21%

The first two ANCC domains total 99 of 125 items, or 79.2%. Professional Role is 20.8%.

The CMSRN comparison uses a Castleport classification: its three systems/interprofessional/professional/team domains total 66 of 125, or 52.8%. Those are not equivalent category definitions, so the percentages should not be read as a scientific head-to-head measure. They do show that the two organizations publish different category structures and emphasis.

MSNCB publishes 132 numbered activity lines in its five-domain blueprint. ANCC’s three-page outline publishes a much shorter numbered list. That means MSNCB publishes roughly seven times as many numbered lines—not that it tests seven times as much knowledge or is seven times harder.

Choose by the credential requirements and exam emphasis that fit your role and timeline. Never study for one using the other’s score, vendor, or blueprint.

Is MEDSURG-BC being discontinued?

No current ANCC retirement notice identified MEDSURG-BC for retirement. ANCC’s current page remains open to new applicants, and its outline was updated June 30, 2026.

Can a MEDSURG-BC holder transfer to CMSRN without testing?

A live AMSN/MSNCB route still presents the transfer pathway. It states:

• MEDSURG-BC certification expiring within one year
• Current, unencumbered RN license
• 1,000 medical-surgical practice hours in the last five years
• 90 verified contact hours in the last five years, including 68 medical-surgical hours
• A one-year grace period after MEDSURG-BC expiration
• Fees shown as $193 member / $303 standard

The same page still contains superseded Prometric logistics, $79 fees, and old ID language. So the route is visible and linked, but the displayed transfer fee should be confirmed before payment.

---

What happens after you pass the CMSRN?

The credential is valid for five years. To renew by contact hours, the current requirements include 1,000 medical-surgical practice hours, 90 verified contact hours, and at least 68 medical-surgical contact hours during the five-year period. Renewal by exam is also available.

Current fees are $225 member / $325 standard by contact hours and $267 member / $394 standard by exam.

Start logging on day one

MSNCB says 10% of recertification applications are selected for audit. Enter activities as you earn them and retain proof.

Rules the current handbook or page spells out:

• ACLS can count once per certification period as medical-surgical contact hours.
• PALS can count once as professional development rather than medical-surgical hours.
• BLS and CPR do not count.
• Eligible AMSN online-library contact hours can transfer into the application record automatically after completion/evaluation.
• Six hours of qualifying precepting = one contact hour, up to 20.
• One academic credit = 15 contact hours, up to 75.

The filing-window conflict

MSNCB’s current recertification page says the credential must expire within one year, and Certification Central guidance points to filing in the fifth year. The January 2026 handbook also says an application may be submitted starting in the fourth year, while another section directs candidates to complete and pay during the last year.

The safest operational plan is simple: enter hours throughout the term, prepare the file early, and use the fifth year for the paid submission unless MSNCB confirms an earlier window in writing.

Grace period change beginning January 1, 2027

For credentials expiring on or after January 1, 2027, the current MSNCB page says the recertification grace period becomes 30 days after expiration. A submission during that 30-day period carries a $90 late fee, and all required contact hours still must have been earned before the original expiration date.

---

Where MSNCB’s own current materials disagree—and what to do

The official record is spread across the certification handbook, recertification handbook, blueprint, current MSNCB pages, and older AMSN-hosted pages. We found 12 places where the record conflicts, duplicates, or lags.

Working rule: use the current handbook and current MSNCB process pages together. When eligibility, money, or a deadline conflicts, obtain the answer from MSNCB in writing.

What Castleport verified—and what remains unresolved

Every check below was performed on August 28, 2026.

Verified

• Exam structure, time, standard score, current five-domain weights, and domestic eligibility
• Current application, retake, extension, recertification, CertAssure, membership, practice-exam, and course prices listed on this page
• Pearson VUE/OnVUE delivery and current scheduling boundaries
• 2021–2025 official statistics and the 2024 table inconsistency
• The 132-line / 28-subarea CMSRN blueprint count, completed twice
• The current new and sunset AMSN review-course listings
• The live MEDSURG-BC transfer route and the stale language surrounding its fee
• Current MEDSURG-BC format, eligibility, fee, testing window, and June 30, 2026 outline update
• Castleport product status: no CMSRN book, paid course, question bank, Exam System, or diagnostic is live

Not resolved by the published record

• Whether international applicants need 1,000 or 2,000 hours
• Whether a recertification application may actually be paid in year four or should wait until year five
• The current transfer fee, because the live route sits on a page with other superseded fees/logistics
• The denominator or scale behind AMSN’s practice-exam activity grade of 120.00
• Why the annual pass rate fell from 75% in 2021 to 67% in 2025

This page contains no Castleport clinical question bank. The supplied pacing drill tests only the clock. Castleport does not use recalled, leaked, or live exam questions.
