Build Your CRRN Study Plan From Your Exam Date

The CRRN exam is offered twice a year, in June and December, and the Rehabilitation Nursing Certification Board (RNCB) does not give it outside those two windows. It is 175 multiple-choice questions in three hours. Only 150 are scored. You pass with a scaled score of 500. It costs $300 for ARN members and $460 for everyone else.

So that is your CRRN exam prep problem in one sentence: this is not really a studying problem yet. It's a calendar problem.

To sit in December 2026, your application has to be in by October 15, or by November 1 with a $100 late fee. Miss both and your next seat is roughly six months away. As of today that gives you 48 days to decide and about 13.6 weeks to prepare before the window opens.

And here's the part almost nobody tells you before they take your money: only 53% of this exam is bedside clinical content. The other 47% — about 70 of your 150 scored questions — is theory, team process, discharge, law, reimbursement, ethics, safety, and quality improvement. If you're a strong rehab nurse who studies rehab nursing, you have prepared for barely half of the test.

We'll show you exactly where those questions live, and what to do about it.

Build your plan first: The CRRN 175 Plan

Before you read another word, put your date in. The CRRN 175 Plan does five things, free, with no sign-up:

• Counts the days to your real application deadline, not a generic one
• Splits the official blueprint across the weeks you actually have
• Adjusts for your weak domains using a self-rating, so your hours go where you need them
• Checks your study material against 16 signals that date a resource to the wrong version of this exam
• Prints the whole plan on one page

It is a planner, not a diagnostic. It does not score you and it does not predict whether you'll pass. Nothing can do that honestly.

→ Pick your window and see how many days you actually have.

---

This page is for you if…

You're an RN in inpatient rehab, a rehab unit, a skilled nursing facility, an LTACH, home health, or outpatient rehab. You have decided you want the CRRN, or you're close. You want to know when you can sit it. What is really on it. And what it costs before you spend a dollar.

This page is not for you if…

• You're an LPN or LVN. The CRRN requires an RN licence. There's no pathway around that one.
• You're licensed outside the US, its territories, or Canada. RNCB's test sites are limited to those, so the CRRN isn't currently open to you.
• You're looking for the old ANCC RN-BC Rehabilitation credential. That one is retired. The CRRN is the active RN-level rehabilitation nursing certification.
• You meant the CCRN. Different exam, different board — that's critical care, from AACN. Easy letters to mix up.
• You meant med-surg. That's the CMSRN, from MSNCB.
• You're already certified and looking to renew. Skip to the renewal section near the bottom — different rules entirely.

---

The right prep path isn't the same for every candidate. It depends on which window you'll actually sit, which eligibility route you're on, how current your study material is, and how far you are from passing today. The official handbook and RNCB set the requirements — not a checklist on somebody's website. Because a general answer can't resolve those for you, run your date and your materials through the CRRN 175 Plan above and see exactly where you stand before you spend anything.

Castleport Test Prep is the independent exam prep publisher that matches every study material to the exact exam version and jurisdiction you're testing under — every requirement verified against the official handbook, every product updated when the blueprint changes.

---

When can you actually take the CRRN exam?

The CRRN exam runs in two month-long windows a year: June 1–30 and December 1–30. The candidate handbook says the exam is not given outside them. You must apply at least 45 days before a window opens. That sets the deadlines at April 15 and October 15, with a 15-day late period after each for an extra $100.

This is the single biggest difference between the CRRN and almost every other nursing certification you might have taken. The CCRN, the CMSRN, the CEN — those run year-round. You decide you're ready, you book a seat, you sit. The CRRN does not work that way. There are two doors a year and they are both on a timer.

That changes everything downstream. It changes how you plan. It changes what a failed attempt costs you. And it means the most expensive mistake on this exam isn't a wrong answer — it's a missed date.

The full calendar, deadline by deadline

ARN publishes dated deadlines only for the current cycle. The 2027 rows apply the handbook's standing rule — 45 days before the window, then a 15-day late period — to the published June and December windows. Confirm 2027 dates with ARN before you rely on them.

Nobody schedules you. You schedule yourself.

Roughly 40 days before the window opens, you'll get a "Notice to Schedule" by email. That's your cue to go book an actual appointment — a date, a time, and either a test centre or a remote slot. Seats are first come, first served, and the handbook warns that late applicants may not get their first choice of date, location, or time.

Two practical consequences. First: check your spam folder. The handbook explicitly tells you to whitelist the vendor's address, and it puts the responsibility on you to call if the notice doesn't arrive. Second: applying on the last possible day and then scheduling on the last possible day is how people end up sitting a three-hour exam at 7 a.m. ninety minutes from home.

How long your application stays alive

Your application is good for two consecutive testing windows and can be transferred once. If you don't schedule and sit within that span, the application closes and the fee is forfeited. You start over — new application, new payment.

There's also a shorter fuse most people miss. Start an online application and don't submit it, and it is closed after 90 days. You begin again from scratch.

The December window has a date problem

This one is small, real, and worth thirty seconds of your attention.

• The candidate handbook says the December window runs December 1–30.
• ARN's application page says December 1–31.
• The handbook's own holiday list blacks out December 24, 25, and 31 — including a date its window text says is already outside the window.

Both the current handbook and the superseded 2021 edition carry the same split, so this isn't new. We're not going to guess which one governs, and you shouldn't have to.

The practical answer: plan to sit before December 24. Do that and the conflict cannot touch you. You also avoid the last-week scramble for appointments, which is real.

When will you actually get your result?

Here's a change nobody in the prep field has flagged. The October 2021 handbook said you would get your score report after finishing at the test centre. The current February 2026 handbook drops that sentence. It now says only that candidates get an email with instructions for an online score portal.

The current handbook commits to no results date at all. The only dated milestone it gives is the digital badge: by July 31 for June sittings, by January 31 for December sittings.

Testing in December because a job, a ladder step, or a differential depends on it? Plan around January 31. Do not plan around walking out of the test centre with a number in hand.

What's actually on the CRRN exam?

The current CRRN blueprint has four domains, and only one of them is bedside care. Functional Health Patterns is 53% of the exam. The other three cover theory, team work, and the rules and money side of rehab. Applied to 150 scored questions, the four split into roughly 12, 80, 18, and 41 questions. The table below names each one.

We hand-counted every enumerated knowledge and skill statement in the current content outline. Here's how they distribute.

The official outline contains 187 task-and-knowledge statements, but that count is not a question-frequency map. Use the official content percentages—not the number of bullets under a topic—to allocate study time.

Question counts are the published percentages applied to 150 scored items. RNCB publishes percentages, not a guaranteed number of questions from each domain on any given form, and the 25 unscored pretest questions are mixed in and can't be identified. Treat these as planning equivalents, not promises.

The 53/47 split

Add up everything that isn't Domain II and you get 47% of the exam. That is about 70 scored questions. They cover theory and team work. Discharge and community resources. Federal law and the money side. Ethics, safety, and quality.

Domains III and IV together are 39%, or roughly 59 questions, of content that has nothing to do with a bedside assessment.

We say this plainly because the alternative is watching good nurses fail a test they knew the clinical content for.

Why the CRRN feels broader than your actual job

Because it is broader than your actual job. That's not a flaw in the exam — it's the design.

RNCB writes the CRRN as a generalist credential. Its own list of qualifying roles goes well past staff nurse. Case manager. Nurse liaison. Insurance nurse. In-service instructor. Administrator, consultant, researcher. Its list of settings runs from a rehab facility to an insurance company to a school.

The blueprint has to cover all of them. So it tests things a staff nurse never touches on a Tuesday. How CARF differs from The Joint Commission. What a prospective payment system does to admission decisions. What the IMPACT Act standardises. How a PDCA cycle differs from a root cause analysis.

Your experience is a real advantage on the 53%. It is close to no advantage at all on the 27%. Plan accordingly.

There is no easy domain on this exam — and that's unusual

Look at the last column of the table again. On most certification exams we map, that number swings hard between domains. One area gives you a question for every half-topic you learn; another makes you learn three topics to earn one. That gap is where a smart candidate finds leverage.

On the CRRN, the spread from tightest to loosest is 1.37 times. That is the flattest blueprint we've measured on any exam. RNCB wrote the outline so that each listed topic carries almost exactly the same weight.

You cannot outsmart this blueprint. There's no cheap domain to farm and no expensive one to skip. The only sensible move is to allocate your hours straight down the published percentages, which is exactly what the planner above does.

We'd rather tell you that than invent an edge that isn't there.

The one real edge that does exist

Domain IV lists 41 topics for about 41 questions — a ratio of 1.01, the tightest on the exam. Roughly one listed topic per scored question.

And unlike clinical judgment, that content is finite. The outline names it all outright: CARF, The Joint Commission, CMS, SSA, OSHA, APS and CPS. Medicare, Medicaid, the ADA, HIPAA, the Affordable Care Act, workers' compensation, IDEA, the IMPACT Act. Prospective payment systems, utilisation review, regulatory audit processes. PDCA, Six Sigma, Lean. AHRQ, the Institute of Medicine, NDNQI. Safe patient handling, restraint alternatives, de-escalation.

That's a list. Lists can be learned. The domain you're most tempted to skip has the best points-per-topic on the exam, and it's the one where your years on the floor help you least — which is precisely why it's worth protecting time for.

That's our editorial read, drawn from the counts above. But you can check the arithmetic yourself, which is the point.

---

What should you study first for the CRRN exam?

Start with the official weights. Then shift time toward your weakest domains without dropping the weights. For most people that means guarding a block for Domain IV early. It is 27% of the exam. It is the most memorisable part of the outline. And it is the area where floor experience helps you least.

Here's the baseline allocation at three realistic study budgets.

Then adjust. The planner uses one simple multiplier. Rate your confidence in each domain from 1 to 5. It multiplies that domain's weight by 1.50 at the low end, down to 0.70 at the high end, then normalises everything back to 100%.

That shifts your study time. It does not change the exam weights, and no tool can. Domain II is 53% of the test whether you feel good about it or not.

If you have eight or more weeks

Run the outline once, domain by domain, in weight order. Finish the first pass with three weeks left. Spend those three weeks on timed mixed sets and on whatever your first pass exposed.

If you have four to seven weeks

Do Domain IV first, while you're fresh and before life eats your evenings. It's the block most likely to get dropped if you leave it to the end, and it's 27%. Then Domain II. Then I and III together — they're 20% combined and they overlap more than you'd expect.

If you have two weeks or less

Be honest with yourself about whether this is the window. If it is, don't attempt a full pass. Take Domain IV's named list and learn it cold, drill Domain II's highest-frequency areas — mobility, skin, bowel and bladder, neuro, swallowing — and practise at pace. Accept that you're playing for the margin.

What not to do

Don't read a 700-page core curriculum front to back with three weeks left. Don't build a plan around a pass rate you found online. Don't study only what you already like. And don't buy a second book because the first one felt hard — that's usually the study method talking, not the material.

---

How many questions are on the CRRN exam, and how fast do you have to move?

The CRRN is 175 questions in 180 minutes. Only 150 count. The other 25 are unscored pretest items being trialled for future exams. They are mixed in and you cannot spot them. So your working pace is 61.7 seconds per question across all 175.

Both numbers you'll see online are correct, which is why they confuse people. 175 is what you sit. 150 is what counts. Roughly 86% of your answers matter and you'll never know which ones.

Practise against 61.7 seconds, not against 72 seconds. Here's what that looks like on a drill.

Halfway is question 87 at about 89 minutes. If you're past 95 minutes at question 87, you need to speed up, and it's better to know that at minute 89 than at minute 170.

There are no breaks

The handbook is blunt about this: no breaks are permitted. Three hours, straight through. Plan your coffee accordingly.

One detail catches people out. If you are approved for extended time, you get one break — but the timer keeps running through it. Read that twice if you are asking for accommodations.

Answer everything

There's no penalty for guessing. Every blank counts exactly the same as a wrong answer, so a blank is a pure loss.

The handbook itself gives the strategy: answer the easy ones first, skip the ones that need thought, and come back. On a 61.7-second average, two minutes spent staring at one hard item costs you the time you needed for two easy ones later.

---

What score do you need to pass the CRRN exam?

You need a scaled score of 500. RNCB does not publish how many right answers that equals. It uses several forms of the exam and adjusts each one for how hard it is. So there is no fixed "X out of 150" target on this exam.

Let's define the terms, because they get thrown around loosely.

A scaled score is a converted score. RNCB takes your raw number correct and converts it onto a common scale so that candidates who sat a slightly harder form aren't punished for it. Equating is the statistical procedure that makes that adjustment. It's why 500 means the same level of ability no matter which form you got.

The passing point is set by a method called Modified Angoff. A panel of rehab nursing experts looks at each question. They estimate the odds that a just-barely-competent nurse would get it right. Those judgments get averaged and adjusted for measurement error. It is a judgment standard, not a curve. You are not competing against other candidates.

Why "you need 71%" is not something we'll publish

ARN now publishes an official CRRN certification statistics page. Use that page for the current testing-volume and pass-rate figures—not an undated percentage from a prep company. The honest answer to "how many can I miss?" is that it depends on which form you sit.

You will find pages that give you a percentage anyway. They're guessing, and a target that's five questions off in the wrong direction is worse than no target.

What your score report includes — and what costs extra

Your score report tells you whether you passed and gives subscores by content area. That's useful.

The full diagnostic report is different. That is the detailed breakdown by area, and it costs $50 through the vendor's score-review form. It does not arrive on its own. A comparative review, which rechecks your answers against the key, is also $50.

If you don't pass, order the diagnostic. It's the only way to find out where you actually lost the exam, and $50 against a $300–$460 second attempt is cheap information.

Does RNCB publish a CRRN pass rate?

No. We searched the current handbook, the superseded 2021 handbook, and RNCB's and ARN's certification pages. There is no published CRRN pass rate.

Figures circulate anyway — you'll see "65–75%," "68–77%," and "approximately 70%." None of them cites a source. They don't agree with each other. And one well-ranked page publishes a range while stating, in the same breath, that RNCB doesn't release figures.

Here's the thing: you couldn't act on a pass rate even if it were real. It wouldn't change one hour of your plan. The numbers you can act on are the four domain weights and your own timed practice, and both are on this page.

---

Are you eligible to take the CRRN exam?

You need a current, unrestricted RN licence in the US, a US territory, or Canada. Then one of two routes. Route A is two years of rehab nursing in the last five years. Route B is one year of rehab nursing plus one year of advanced study in nursing beyond a bachelor's degree. There is no hours requirement.

Both routes must be satisfied at the time you apply, not at the time you sit.

There is no hours requirement — and here's where that myth comes from

You will find pages saying you need 2,000 practice hours to sit the CRRN. You'll find others saying you need two years of general RN experience and one year of rehab experience. That combined rule appears in no RNCB document we read.

Both are wrong, and the second is the more dangerous one because it tells an eligible nurse she isn't.

The mix-up is understandable. CRRN renewal does have an hours rule — 1,000 hours of rehab nursing across your five-year term. Some writers push it backwards into initial eligibility. It does not belong there. To sit the first time, RNCB asks for a length of practice, not a count of hours.

If you've been in rehab two years, you're eligible. Full stop.

The two colleagues you have to name

Your application asks for contact details for two colleagues. Their job is to confirm your rehab nursing experience.

• One must be your immediate supervisor or another CRRN.
• The second can be any other professional colleague — a nurse, physician, therapist, or social worker.

A percentage of applications is randomly audited, and if yours is selected, those two people get contacted directly and asked to confirm your experience. Give them a heads-up when you apply. An audit that stalls because someone thought the email was phishing is a genuinely avoidable way to lose a window.

If you don't have a supervisor or a CRRN colleague

There is a door here a lot of nurses miss, and ARN's live pages are more generous than the handbook. The handbook names alternative verification only for nurses in independent practice with no supervisor or CRRN colleague. ARN's own pages go further. They extend it to nurses who left paid work to care for a family member.

If that's you — and it's a lot of people, more than the field ever accounts for — you are not locked out. There's an alternative verification application. Ask ARN for it rather than assuming you can't be verified.

How much does the CRRN exam cost, and does joining ARN pay for itself?

The CRRN exam costs $300 for ARN members and $460 for everyone else. Applying late adds $100. ARN lists membership starting at $13 a month. That is $165 a year — less than the $160 the membership saves you on the fee.

Here is every dollar RNCB and its vendor charge, checked August 28, 2026.

Does joining ARN pay for itself? Yes — on the exam fee alone.

The break-even dues rate is $13.33 a month. At ARN's published starting rate, the exam discount covers your membership with a few dollars to spare, and you keep the membership for a year.

Then it widens. ARN's own prep packages are cheaper for members too:

ARN publishes "$13/month" as a starting rate and puts exact dues behind the join flow, so check your own tier before you rely on this. But the shape of the answer is clear: if you were going to buy anything from ARN at all, joining first is free money.

Two ways to lose the $160

1. Student membership doesn't count. ARN's Student Membership explicitly excludes discounts on the CRRN test and renewal. It's the cheapest tier and it's the one a nurse enrolled in a graduate program — exactly the Route B candidate — is most likely to reach for. It will not save you a dollar on this exam.

2. Order of operations. ARN states your membership must be current at the time you submit your application, and its own instructions say to allow 24 hours for a new membership to process. Join, wait a day, then apply. Do it backwards and you pay $460.

What the fees have done since 2021

We put the current fees next to the ones in the October 2021 handbook.

The exam fee has barely moved in five years. The late fee nearly tripled. Whatever RNCB's reasoning, the message to candidates is unambiguous: the penalty for missing October 15 got a lot more expensive, and it's now a third of the member exam fee.

One thing the current handbook stopped telling you

The 2021 handbook printed a $65 fee to cancel an application. The current handbook explains the process in more detail. But it names no dollar amount at all. It points to "the initial application fee and the application cancellation fee" without saying what either one is.

Practical effect: you cannot calculate your own refund from the current handbook. If you think you might need to cancel, ask ARN for the figure in writing before you pay.

There's one more fee gap worth knowing. The handbook attaches the $50 admin fee to in-person reschedules, cancels, and window transfers. It states no fee for the at-home versions. That may be real or it may be an omission. Ask the vendor before you assume a remote change is free.

Is your CRRN study guide using the old blueprint?

The CRRN blueprint changed in 2022, and about nine scored questions moved between domains. Domain IV grew from 23% to 27%. Functional Health Patterns dropped from 58% to 53%. Study material built on the old weights spends too long on clinical content and too little on the rules-and-money domain.

We read the superseded October 2021 handbook against the current one and diffed them line by line. Here's what moved.

The outline itself grew too — from 169 statements to 187, up 10.7%. Domain IV's own statement count grew 36.7%, from 30 to 41. It didn't just get more questions; it got more material behind them.

What was added to the exam

The 2022 update pulled new clinical ground into a rehab blueprint:

• LVAD and assisted ventilation, named for the first time
• Central lines, ports, and catheters — including a skill statement about teaching patients and caregivers to care for them
• Enteral and parenteral nutrition and hydration
• Cultural and religious practices related to dietary habits
• Safe patient handling, infection control, risk mitigation, and behavioural management as named Domain IV knowledge
• De-escalation technique, named explicitly

The old outline had one task for quality and safety. It split in two. One task now covers safe environment of care. The other covers quality improvement.

What quietly left — and the one you should keep studying anyway

Three things were cut from the outline's named examples. FIM and WeeFIM under team goal setting. SMART goals. And IRF-PAI under legislation.

Now here's the catch, and it's the kind of thing you only find by reading two documents against each other.

A FIM scoring question is still one of the fifteen sample questions RNCB publishes in the current February 2026 handbook. The examples came out of the outline. The sample item did not.

So: don't stop studying FIM. Its disappearance from the outline is a change in how RNCB writes its examples, not evidence that functional independence scoring left the exam.

The version test: check your resource in about a minute

Open the table of contents or the overview page of whatever book, course, or website you're considering. Look for any of these.

The bottom three are different in kind from the rest. A stale percentage means a resource hasn't been updated. Naming Prometric, or a 90-day ATT, or a 2,000-hour rule means the writer never opened the handbook at all. If you see one of those, close the tab.

The reassuring half of the version story

We diffed the 2022 content outline against the outline printed inside the February 2026 handbook. They match, word for word.

That means the CRRN blueprint has been stable for four years. A study resource built to the 2022 outline is not automatically out of date on content. What ages on this exam isn't the blueprint — it's the logistics. Fees, vendor names, browser requirements, and deadlines have all changed since 2022. The content hasn't.

→ Run the version test on the book you already own. It takes about a minute.

Which CRRN prep option fits your situation?

ARN is the parent group of the certifying board, and it sells the study materials closest to the current outline. Prices run from $35 to $699. Other options exist and often cost less, but you have to check their blueprint version yourself. RNCB endorses no review course — not even ARN's.

ARN prices verified from ARN's live self-study page on August 28, 2026. We deliberately left the third-party row's price column empty rather than publish a figure we didn't read ourselves that day.

The $35 observation

If you learn by doing questions, the Starter Prep Kit is the cheapest route to 450 blueprint-matched practice questions we found anywhere. Three full-length 150-question exams for $35 as a member, $45 if not.

That is a striking price for the volume, and it's from the organization whose board writes the exam. We're not being paid to say that. We just couldn't find anything close.

Do you need a book, a question bank, flashcards, or a course?

The format that fits is usually determined by what's actually going wrong.

• Choose a book if you need one coherent reference and your gaps are broad. A core curriculum is worth it when you genuinely don't know Domain IV exists. It's a poor choice with three weeks left.
• Choose a question bank if you know the material but keep missing questions. Question banks diagnose. Books explain. If you can't tell which problem you have, do 25 timed questions and count.
• Choose flashcards only if recall is the narrow problem — drug classes, scale levels, acronyms. Flashcards don't teach application, and this exam is heavily applied.
• Choose a course if you need structure, accountability, or live teaching. It's the most expensive option and the right one for people who won't otherwise open the book.

Don't buy duplicates. Two question banks is almost always worse than one bank you finish. The most common money mistake we see isn't buying the wrong thing — it's buying a second thing to avoid finishing the first.

If your employer is paying

Ask before you buy, and ask about CE in particular. The Comprehensive bundle carries 32 contact hours. That changes the money conversation at a lot of places. Many rehab employers will pay for prep and the exam outright. That is doubly true if the unit holds CARF accreditation or is going for it.

One caution on CE, and it's counterintuitive: contact hours you earn while preparing do not count toward your first CRRN renewal. Renewal points must be earned inside your five-year certification period, and that period doesn't start until you pass. Prep CE counts toward your licence. It does not bank against renewal.

"Official" prep is not official exam content

Worth saying plainly, because the branding blurs it. Here is RNCB's own line, printed on ARN's study pages: RNCB does not sponsor or endorse any review course or prep material. Using one is not required to sit the exam. And it does not make you pass.

ARN's materials are built by people close to the outline. That's a real advantage. It is not the same as the exam.

---

How long should you study for the CRRN exam?

There is no official recommended study time. Any page that gives you one as official is guessing. What works is backwards planning. Fix your window, count the weeks you have, and split the hours by the official weights. Most people who prepare seriously land between 20 and 60 total hours.

Right now, testing in December 2026, you have about 13.6 weeks before the window opens. Here's what that looks like at three commitment levels.

An eight-week schedule that works

How to shorten it safely

If life compresses your plan, cut in this order: drop the second full-length practice exam, drop your strongest Domain II subtopics, then reduce Domain I. Do not cut Domain IV. It's 27% of the exam and it's the block your day job doesn't cover.

---

What happens on CRRN exam day?

You can sit the CRRN at a Meazure Learning test centre or at home with a live proctor. Both run three hours with no breaks. Both need government-issued photo ID with a signature. The at-home option has device and browser rules that catch people out every window.

Test centre or remote?

ID that works, and ID that doesn't

Accepted: state-issued driver's licences, government-issued passports and identification cards. Photo and signature required.

Not accepted: gym memberships, warehouse club cards, school ID, credit cards, and any ID with a signature but no photo.

Arrive 15 minutes early at a test centre and bring your printed confirmation notice. Arrive late, or not at all, and you forfeit the appointment and the entire fee.

The browser trap

This one is small and it will end somebody's window.

The 2021 handbook supported Internet Explorer 11, Edge, Firefox, Safari, and Chrome. The current one lists only Firefox and Chrome. It recommends Chrome.

Edge and Safari are gone. If you're a Mac user who lives in Safari, that's your exam day, not a footnote. The handbook also excludes tablets, smartphones, and Chromebooks — desktop or laptop only — and asks for at least 2 Mbps up or down.

Run the system check the week before, not the morning of.

What ends a remote session

The handbook is direct about this. Before you start, you scan the room with your webcam to show you're alone and the area is clear. Camera and microphone stay on for all three hours. And: if another person enters the area, or there appears to be a disruption or other irregularity, the examination will end.

If you have kids, roommates, or a dog with opinions, pick the test centre. It's three hours.

The final seven days

• Day 7: Confirm your appointment, location, and time. Print the confirmation.
• Day 6: Run the full system check if you're testing remotely. Fix problems now.
• Day 5: One full-length timed practice exam. Review every miss.
• Day 4: Domain IV review — the named agencies, laws, and QI models.
• Day 3: Your weakest Domain II topics only.
• Day 2: Light review. Reread the scoring and rules pages of the handbook.
• Day 1: Locate your ID. Plan the route or clear the room. Stop studying by early evening.

Nothing you learn on day 1 shows up on the score report. Sleep does.

What happens if you fail the CRRN exam?

You can retake the CRRN as many times as you need — RNCB sets no attempt limit. But you must reapply for the next testing window, roughly six months away, and pay the full fee again. There is no discounted retake and no shorter waiting period.

That's the honest picture, and it's why this exam rewards not rushing a window you're not ready for.

Use the six months, don't just wait them out

Order the $50 diagnostic report. Your standard score report gives you subscores; the diagnostic gives you the full area-by-area breakdown. On a six-month runway with a $300–$460 second attempt ahead of you, it's the single best fifty dollars in this whole process.

Then look at where the loss actually was. In our experience with the structure of this blueprint, the likeliest answer is not the clinical domain. It's the 47% that isn't.

Reapplying means a new application and full payment. If your name changed, send the legal document — a marriage licence or divorce decree — with it.

What not to conclude

A failed attempt is not evidence you're a weak rehab nurse. The CRRN tests a generalist blueprint that spans roles most nurses never hold. Missing the reimbursement and quality questions means you didn't study them. It doesn't mean you can't do the job — you already do it.

How do you keep your CRRN once you have it?

CRRN certification lasts five years. The clock starts the last day of the month you passed. You renew one of two ways. Earn 60 points of credit plus 1,000 hours of rehab nursing in that time. Or take the exam again in the year before it runs out.

The points system has category caps. That matters, because continuing education is the only category that can get you all 60 on its own.

Two-thirds of your CE points must be approved for nursing contact hours by a national or state nursing group. And note what does not count. ACLS. Plus anything that meets a mandatory annual review — CPR, bloodborne pathogens, fire and safety. Those are hours most rehab nurses rack up anyway, and none of them help here.

The timing rule is the one that catches people: points must be earned inside the five-year certification period. Not before it starts, not after it ends.

Where ARN's own pages disagree with each other

We read every current RNCB and ARN page against the February 2026 handbook. Several official pages say different things about fees, dates, and vendor names. When two pages clash, trust two things. Trust the dated candidate handbook for the exam. Trust the live application page for fees and deadlines.

We're publishing these because you're going to hit them yourself and wonder which page is right.

None of this means ARN is careless. It means a large organization maintains some pages more often than others — which is exactly why we date every figure on this page and tell you which document we read.

The rule that resolves all of it: the dated candidate handbook governs the exam, and the live application page governs fees and deadlines.

What we actually verified

Is the CRRN worth it?

The CRRN is the only active RN-level rehab nursing credential in the United States. A national body has accredited it since 1992. ARN reports more than 13,000 nurses hold it now. Whether it is worth it to you comes down to one thing: what your own employer does with it.

That last sentence is the honest one, and it's the one most pages skip.

The limitation nobody states

There is no CRRN salary figure, because no federal agency publishes earnings by certification. The Bureau of Labor Statistics reports pay by occupation, not by credential. Anyone showing you a "CRRN salary" is showing you a registered nurse salary with a credential name attached to it.

We're not going to invent a number to make this feel more exciting.

The number that actually matters is your employer's. Many rehab facilities pay a certification differential or a clinical ladder step. Some pay for the exam. Some do neither. That's a five-minute conversation with your manager, and it will tell you more than any national average ever could.

Ask three questions: Is there a differential for CRRN? Will you reimburse the exam fee? Will you reimburse prep? At a lot of CARF-accredited and Magnet-recognised facilities, the answer to all three is yes — they need certified nurses on the floor for their own accreditation reasons.

What it costs, all in

Plus the calendar risk: if it doesn't go your way, the next window is six months out and the fee resets.

Who should probably wait

• Under two years in rehabilitation nursing. You're not eligible yet, and the exam rewards accumulated exposure.
• Planning to leave rehab within a year. The credential is specialty-specific and renews on a five-year clock.
• No employer recognition and no personal pull toward it. If nobody's paying and nothing changes, there's no shame in waiting for a window when there's a reason.

Everyone else: the constraint is the calendar, not your readiness. There are two doors a year, and the next one closes on October 15.

→ If the answer is yes, the only thing between you and a seat is a date. Open the CRRN 175 Plan and build your schedule.

Your next step

If you take one thing from this page, take the date. October 15 for December. April 15 for June. Everything else on this page is useful; those two dates are the ones that actually gate you.

Then take twenty minutes with the planner. Put in your window, your honest weekly hours, and your honest confidence in each of the four domains. It will hand you a week-by-week schedule weighted to the official blueprint, and it will tell you whether the book on your shelf is describing the exam you're about to sit.

→ Build your CRRN study plan — free, no sign-up, printable.

And if you're reading this in November wondering whether to rush an application for a December window you're not ready for: don't. Take June. Study Domain IV properly. Walk in knowing you covered the 47% everybody else skipped.

How this page was made

Written by the Castleport Test Prep Editorial Team. We read the current CRRN candidate handbook end to end. We diffed it against the superseded 2021 edition. We hand-counted both content outlines. And we checked every fee against the live page on the date shown. Where two official sources disagree, we show you both and say which one governs. Where we could not check something, we say so above.

We built this page because rehab nurses were being handed study plans built on a blueprint that changed in 2022. And deadlines from a calendar that only opens twice a year.

This is study guidance, not legal, licensing, or clinical advice. Confirm every requirement against the current CRRN Examination Candidate Handbook and with RNCB before you apply.

Castleport Test Prep publishes and sells its own exam preparation materials. We do not currently publish CRRN materials and we earn nothing from any product named on this page.
