CRRN

ARN's site identifies the Rehabilitation Nursing Certification Board (RNCB) as the body behind certification and links to RNCB information for recognition and digital badging. ARN itself provides the study materials, review courses, and verification resources. Confirm current application and eligibility procedures with RNCB, since ARN's public pages do not enumerate them.

ARN's public pages describe the certification only in general terms and do not publish an enumerated content outline. The exam tests rehabilitation nursing practice, and ARN's study materials are built around its Core Curriculum, now available digitally as the Rehabilitation Nursing Knowledge Base. Use the official outline from RNCB to plan study priorities.

Those figures are not stated in the source material reviewed, so no number is given here. Item counts, appointment length, and whether breaks are offered are set by the certifying board and can change between exam revisions. Check the current candidate handbook from RNCB before you schedule, and do not rely on numbers from older study guides.

The passing standard is not published in the source material reviewed, so it is not stated here. Passing scores are typically set by the certifying board and may be reported on a scaled basis rather than as a raw percentage. Confirm the current scoring and reporting method in the official candidate handbook.

Fees and retake rules are not given in the source material reviewed and are therefore not stated here. Both are set by the certifying board and may differ for members and nonmembers. Contact ARN or RNCB for current pricing, application windows, and the retake or appeal process before you budget for the exam.

The source material does not state a validity period, so no number is given. ARN does publish a recertification pathway with requirements, a handbook, audit information, deadlines, and an inactive/retired status option. Read the recertification handbook early and track deadlines, because audits require documentation you may need to collect over time.

ARN advertises the CRRN Success Suite of test-preparation packages, CRRN Self Study, virtual and in-person review courses, and the Rehabilitation Nursing Knowledge Base, an online searchable version of the Core Curriculum. The Rehabilitation Nursing Journal also publishes CE articles. Choose based on your gaps rather than buying everything, and start with the official outline.

Start with the official content outline, then take a practice test to find weak domains. Study those domains using the Core Curriculum or Knowledge Base, then return to practice questions to confirm gains. Spread review over weeks rather than cramming, and keep a running list of missed concepts so your final week targets known gaps.

Common causes reported by test-takers include studying from memory of older outlines, skipping the official content outline, and over-relying on one resource. Rehabilitation nursing spans many settings and populations, so narrow preparation leaves gaps. Practice applying concepts to scenarios rather than memorizing definitions, and review every missed item's rationale.

No. The CRRN is a voluntary specialty certification that sits alongside your nursing license; it does not replace licensure or a degree, and it is not required to practice rehabilitation nursing. It signals demonstrated knowledge in the specialty and is used by some employers for recognition or advancement. Verify how your employer treats it.
