- The SCRN exam has 170 items (150 scored, 20 unscored pretest) with a 3-hour limit.
- Hyperacute Care and Acute Care each make up 28% of scored content - over half the exam.
- Registration costs $300 (AANN member) or $400 (non-member) via credit card, tested only in February, May, and September windows.
- Eligibility requires an unrestricted RN license plus 2,080 hours of stroke nursing practice in the prior three years.
What the SCRN Exam Actually Tests
The Stroke Certified Registered Nurse (SCRN) credential is administered by the American Board of Neuroscience Nursing (ABNN), with support from the American Association of Neuroscience Nurses (AANN). If you're wondering exactly what is SCRN or need a plain-language answer to what does SCRN stand for, the short version is this: it's a specialty certification proving that a registered nurse has the clinical judgment to manage stroke patients across the entire care continuum, from the first suspicious symptom in triage through secondary prevention counseling before discharge.
The exam is delivered by PSI Services, either at a physical PSI test center or through PSI's live remote proctoring option, and it is only offered during three annual windows - February, May, and September. That scheduling detail matters more than most candidates realize, because missing a window means waiting months, not weeks, for another shot. If you're mapping out your prep timeline, build backward from your intended testing window rather than picking a "someday" target date.
Eligibility and Registration Mechanics
Before you even open a review book, confirm you meet ABNN's eligibility bar: a current, unrestricted RN license and at least one year of full-time experience (2,080 hours) in direct or indirect stroke nursing care within the previous three years. "Indirect" care counts here, which opens the door to case managers, quality coordinators, and stroke program navigators - not just bedside nurses. For a deeper dive into who qualifies and what counts as stroke-related practice, see our full breakdown at SCRN Certification.
Registration fees are straightforward but worth budgeting for early: $300 for AANN members or $400 for non-members if paying by credit card, with a slightly different structure ($325/$425) for check payments. Given the price gap, it's often worth joining AANN before you register.

Key Takeaway
Register at least 6-8 weeks before your target testing window to guarantee a seat, especially if you want an in-person PSI center rather than remote proctoring.
Domain-by-Domain Breakdown
The current outline reflects ABNN's 2021-2022 job analysis and remains the framework used in the 2026 handbook. Five domains make up the scored content, and their weighting should directly shape how you allocate study hours. For a full walkthrough of every domain with sample topics, see SCRN Exam Domains 2026: Complete Guide to All 5 Content Areas.
Domain 1: Anatomy, Physiology, and Pathophysiology of Stroke (18.7%)
This domain grounds everything else. You need fluency in cerebral vascular territories, the Circle of Willis, and how occlusion location predicts clinical presentation.
- Ischemic vs. hemorrhagic stroke mechanisms
- Vascular territory correlation with symptoms
- Risk factor pathophysiology (atrial fibrillation, hypertension, dissection)
Domain 2: Hyperacute Care (28%)
Tied for the largest domain, this section covers the earliest, highest-stakes window of stroke care - recognition through thrombolytic and thrombectomy decision-making.
- NIH Stroke Scale scoring nuances
- tPA/tenecteplase inclusion and exclusion criteria
- Mechanical thrombectomy eligibility windows
Domain 3: Acute Care (28%)
Equal in weight to Hyperacute Care, this domain tests management once the patient is stabilized past the initial intervention.
- Blood pressure management post-thrombolysis
- Complication recognition: hemorrhagic conversion, cerebral edema
- Dysphagia screening and early mobility protocols
Domain 4: Post-acute Care (12.7%)
This domain shifts focus to rehabilitation planning and interdisciplinary coordination.
- Functional assessment tools and rehab referral criteria
- Psychosocial and cognitive sequelae of stroke
- Discharge planning across care settings
Domain 5: Primary and Secondary Preventative Care (12.7%)
The final domain covers prevention - both for at-risk populations and for patients recovering from a prior event.
- Modifiable risk factor education
- Antiplatelet and anticoagulant therapy selection
- Community screening and public health initiatives
Notice that Hyperacute Care and Acute Care together account for 56% of scored items - more than half the exam. That single fact should drive your study schedule more than any other. Our domain-specific guides go deeper on each area: Domain 1, Domain 2, Domain 3, and Domain 4.
Question Style and Format
SCRN questions are scenario-driven multiple-choice items, not simple recall. Expect a clinical vignette - a patient's presentation, vitals, imaging findings, or timeline - followed by a question asking what you'd do next, what the finding indicates, or which intervention takes priority. This mirrors real bedside decision-making rather than testing isolated facts.
Because passing is criterion-referenced (your raw score converts to a scaled score, with 200 as the passing threshold), there's no fixed percentage-correct target to chase. Instead, focus on consistently applying clinical reasoning across scenario types. If you want a realistic sense of how tough this feels in practice, our analysis at How Hard Is the SCRN Exam? Complete Difficulty Guide 2026 breaks down where candidates typically struggle.
A Domain-Weighted Study Timeline
Generic study techniques like spaced repetition and active recall work, but only when mapped to SCRN's actual weighting. Here's a sample 8-week schedule that allocates time proportionally to domain scoring weight rather than splitting effort evenly across five domains.
Foundation: Domain 1
- Master vascular anatomy and stroke pathophysiology
- Build flashcards for territory-symptom correlations
Deep Dive: Domain 2 (Hyperacute Care)
- Drill NIHSS scoring scenarios
- Memorize tPA and thrombectomy time windows and contraindications
Deep Dive: Domain 3 (Acute Care)
- Practice blood pressure management scenarios
- Review complication recognition case studies
Domains 4 and 5 Combined
- Cover rehab planning and discharge coordination
- Review secondary prevention pharmacology
Full Review and Practice Exams
- Take timed full-length practice tests
- Revisit weak-domain flashcards daily
Weeks 3 through 6 intentionally carry the most weight because Domains 2 and 3 combined represent over half the scored exam. If you're short on time, compress Domains 4 and 5 before you compress Hyperacute or Acute Care review. For the complete week-by-week methodology behind this approach, see our flagship SCRN Study Guide 2026: How to Pass on Your First Attempt.
Building Your Study Resource Stack
Effective SCRN prep blends three resource types: the ABNN candidate handbook (for exact eligibility and blueprint details), a stroke-specific clinical reference or textbook, and realistic practice questions that mirror the scenario-based format. Practicing with questions that simulate the actual test experience - timed, scenario-driven, domain-tagged - matters more for this exam than passive reading, since the SCRN rewards applied reasoning over memorization.
Our practice test platform is built specifically around the five SCRN domains listed above, so you can drill Hyperacute Care and Acute Care questions until the decision trees become automatic, then check your readiness on the smaller domains before test day. Running full-length timed sets on the practice site also helps you build the stamina needed for the 3-hour exam window, which is longer than many nurses expect from a computer-based test.
Key Takeaway
Prioritize practice questions over passive re-reading once you've covered the material once - scenario recognition is the actual skill being tested.
Exam Day Mechanics
You'll take the SCRN either at a PSI test center or via PSI's live remote proctoring, so decide early which format suits your environment and study habits. Remote proctoring requires a private, quiet space and a stable internet connection; test centers remove that variable but require travel and scheduling around available seats.
With 170 questions and a 3-hour limit, budgeting roughly one minute per question leaves a reasonable buffer for the longer scenario-based items. Since 20 of those items are unscored pretest questions you can't identify, pacing consistently across the entire exam - rather than trying to guess which questions "count" - is the only sound strategy.
After You Pass
SCRN certification is valid for five years. Renewal can happen either by retaking the exam or by documenting continued stroke nursing practice hours alongside continuing education credits - a meaningful advantage for nurses who want to avoid resitting a 170-item exam every cycle.
Holding the credential also opens doors beyond bedside stroke units - stroke program coordination, quality improvement roles, and stroke center certification support all tend to prefer or require it.
