Official SCRN Exam Facts
Key Takeaways
- The SCRN is owned by the American Board of Neuroscience Nursing, with PSI providing computer-based test delivery and score reporting.
- The exam has 170 multiple-choice items: 150 scored questions and 20 unscored pretest questions.
- Candidates receive 3 hours, which averages about 64 seconds per item across the full 170-question form.
- ABNN reports results on a scaled-score system with the passing point set at 200, not as a fixed percent correct.
- SCRN certification is valid for 5 years and expires on December 31 of the fifth year after certification.
What the SCRN credential represents
The Stroke Certified Registered Nurse (SCRN) credential is ABNN's formal recognition that a registered nurse has demonstrated the knowledge base needed for stroke nursing practice. It is a specialty certification, not a state license, and it does not replace the RN designation. The exam is built for nurses caring for stroke patients across the continuum, so the tested content moves from recognition and hyperacute treatment through inpatient care, rehabilitation, prevention, and patient education.
ABNN is responsible for the certification program and the exam blueprint. PSI provides computer-based administration at test centers and through live remote proctoring. That distinction matters: use ABNN for eligibility, fees, scoring, and blueprint facts, and use PSI for scheduling mechanics after ABNN approves the application.
Core exam facts
| Official fact | SCRN detail |
|---|---|
| Certifying body | American Board of Neuroscience Nursing (ABNN) |
| Testing vendor | PSI |
| Format | Computer-based multiple choice |
| Total items | 170 |
| Scored items | 150 |
| Pretest items | 20 unscored items mixed into the exam |
| Time limit | 3 hours |
| Passing point | 200 scaled score |
| Credential cycle | 5 years |
Because pretest items are not labeled, treat every question as if it counts. ABNN uses those unscored items to evaluate future exam content, but candidates cannot identify them during testing. The practical conclusion is simple: answer all 170 questions, manage time across the whole form, and avoid spending several minutes trying to decide whether a difficult item is experimental.
How the exam thinks
The handbook describes three levels of tested knowledge: basic knowledge, interpretation, and problem solving or evaluation. Basic knowledge might ask you to recognize a stroke syndrome or define a concept such as penumbra. Interpretation asks you to connect findings, timelines, and patient history. Problem solving asks for the safest nursing action, the best escalation, or the most appropriate next step in a realistic case.
A strong SCRN plan should therefore include more than memorized lists. You need to know vascular anatomy, but you also need to apply it when a stem describes aphasia, neglect, gaze deviation, or posterior circulation symptoms. You need to know thrombolytic and thrombectomy pathways, but you also need to recognize when airway, glucose, blood pressure, anticoagulant history, or neurologic worsening changes the priority.
The blueprint anchor
The current 2026 scored-item map is:
| Domain | Scored items |
|---|---|
| Anatomy, Physiology, and Pathophysiology of Stroke | 28 |
| Hyperacute Care | 42 |
| Acute Care | 42 |
| Post-acute Care | 19 |
| Primary and Secondary Preventative Care | 19 |
Hyperacute Care and Acute Care are the largest domains, but the smaller domains are still large enough to decide a borderline result. Treat the blueprint as a resource allocation tool. Spend the most timed practice on hyperacute and acute cases, but keep enough space for localization, rehabilitation transitions, risk-factor education, and prevention medications.
Candidate action
Before starting a question bank, make a one-page orientation sheet from these official facts. Include the item count, time limit, scaled passing point, five-year credential period, and five domain counts. Put the sheet beside your first two weeks of study so logistics stay connected to content. When practice scores feel uneven, return to the sheet and ask whether the misses come from the largest domains, from foundational localization, or from test-management errors such as over-spending time on one complex case.
