If you care for stroke patients, from the first minutes in the emergency department to the follow-up visit months later, the Stroke Certified Registered Nurse (SCRN)® credential is a way to show that expertise. The exam covers the full stroke continuum, so it can feel like a lot to organize at first. The good news is that the American Board of Neuroscience Nursing (ABNN) publishes exactly how many questions come from each area, and a study plan built on that outline makes a first-try pass very realistic.

In this guide, we’ll walk you through the exam format, all five content domains and their item counts, the official resources worth reading, and the questions candidates ask most often.

What Is the ABNN SCRN Exam?

The SCRN is a specialty certification for registered nurses who care for patients with cerebrovascular disease. It is awarded by ABNN, the certifying body affiliated with the American Association of Neuroscience Nurses (AANN), and the program is accredited by the Accreditation Board for Specialty Nursing Certification (ABSNC).

The exam tests whether you can apply stroke knowledge at every phase of care: recognizing stroke and its mimics, managing thrombolytic and endovascular therapy, preventing complications on the unit, planning rehabilitation, and teaching patients how to prevent a second stroke. ABNN writes items at three levels (knowledge, interpretation, and problem-solving or evaluation), so expect many questions that ask for the best or first nursing action rather than a simple definition.

What Is the ABNN SCRN Exam Format?

Here is the exam at a glance, based on the SCRN 2026 Candidate Handbook and the ABNN SCRN exam page:

  • Questions: 170 multiple-choice questions.
  • Scored vs. unscored: 150 scored questions and 20 unscored pretest questions. Pretest items are mixed in, so treat every question as if it counts.
  • Time: 3 hours (180 minutes), or a little over a minute per question.
  • Delivery: Computer-based testing through PSI, either at a PSI test center (about 300 locations in the U.S. and internationally) or by live remote proctoring.
  • Testing windows: The exam is offered only during set windows. For 2026, those were February, May, and September, each with an application deadline about three to four weeks before the window opens.
  • Scoring: The passing point is set by a panel of stroke nursing experts using a criterion-referenced method, then converted to a scaled score. A scaled score of 200 is required to pass.
  • Results: You receive pass/fail results at the test center (or by email if you test remotely). Digital badges are issued within 4 to 6 weeks.

What Content Outline Does the SCRN Exam Use?

The current exam follows the content outline published in the SCRN 2026 Candidate Handbook. ABNN updates the outline through a job analysis about every five years, and the most recent study was completed in summer 2022.

ABNN lists item counts rather than percentages. Here is how the 150 scored questions break down, with approximate percentages calculated from those counts:

  • Domain I, Anatomy, Physiology, and Pathophysiology of Stroke: 28 items (about 19%)
  • Domain II, Hyperacute Care: 42 items (28%)
  • Domain III, Acute Care: 42 items (28%)
  • Domain IV, Post-acute Care: 19 items (about 13%)
  • Domain V, Primary and Secondary Preventative Care: 19 items (about 13%)

Hyperacute and acute care together make up 84 of the 150 scored items, more than half of the exam.

Domain I: Anatomy, Physiology, and Pathophysiology of Stroke (28 items)

This domain is the foundation for everything else. You need to link a vascular territory to the deficits you would expect, and tell a true stroke from a condition that only looks like one.

  • Vascular anatomy and brain structure, including the anterior and posterior circulation and the circle of Willis.
  • Stroke types (ischemic, intracerebral hemorrhage, subarachnoid hemorrhage) and associated disorders and etiologies.
  • Stroke syndromes, such as a middle cerebral artery (MCA) syndrome versus a posterior circulation stroke.
  • Stroke mimics, such as hypoglycemia, seizure with postictal (Todd’s) paralysis, migraine, and conversion disorder.
  • Neuroplasticity and cellular changes, including the ischemic penumbra.

What questions look like: A stem describes contralateral arm and face weakness with aphasia, and you identify a left MCA stroke. Or a patient with sudden weakness has a blood glucose of 42 mg/dL, and the best answer treats the hypoglycemia before anything else.

Domain II: Hyperacute Care (42 items)

Hyperacute care covers the first hours, when time equals brain. This is where thrombolytics, thrombectomy, and quality metrics live.

  • Initial triage, assessments (including the NIH Stroke Scale), and diagnostic tests such as noncontrast CT and CT angiography.
  • Treatment considerations and thrombolytic therapy, including eligibility, dosing, and blood pressure limits.
  • Hemorrhagic and ischemic interventions, and advanced interventions such as mechanical thrombectomy and surgery.
  • Complication management, medications, and patient disposition.
  • Quality stroke metrics, such as door-to-needle time.

Study tip: Know the numbers cold. Blood pressure must be below 185/110 mm Hg before thrombolysis and kept below 180/105 mm Hg for 24 hours afterward. Alteplase is dosed at 0.9 mg/kg (maximum 90 mg), with 10% as a bolus over 1 minute and the rest over 60 minutes.

Domain III: Acute Care (42 items)

Acute care is the stroke unit or ICU phase. The focus shifts to monitoring, preventing complications, and starting recovery.

  • Assessment and diagnostic tests after admission, plus hemorrhagic and ischemic interventions.
  • Complication management, such as cerebral edema, hemorrhagic transformation, aspiration pneumonia, and venous thromboembolism.
  • Multidisciplinary plan of care, safety measures, and individualized care for activities of daily living.
  • Therapeutic environment (for example, sensory stimulation and positioning) and psychosocial care.
  • Education, medications, quality metrics, and early rehabilitation and discharge planning.

What questions look like: A patient is two days out from a large ischemic stroke and becomes harder to arouse. You need to recognize possible cerebral edema and escalate, not chalk it up to fatigue.

Domain IV: Post-acute Care (19 items)

This domain follows the patient after the acute stay. It asks you to match the patient to the right level of rehabilitation and support long-term recovery.

  • Multidisciplinary plan of care and goals of rehabilitation.
  • Levels of rehabilitative care, such as inpatient rehabilitation, skilled nursing, home health, and outpatient therapy.
  • Rehabilitation considerations, including spasticity and safety.
  • Stroke education, medication management, and community resources such as support groups.

Study tip: Acute care nurses often find this domain unfamiliar. Review the general criteria for inpatient rehabilitation versus skilled nursing, and common problems such as post-stroke depression and shoulder subluxation.

Domain V: Primary and Secondary Preventative Care (19 items)

Prevention questions ask how to stop a first stroke or a recurrence. They combine risk-factor knowledge with patient teaching.

  • Comorbidities and stroke risk factors, such as hypertension, atrial fibrillation, diabetes, dyslipidemia, and smoking.
  • Prevention measures and social determinants of health.
  • Diagnostic tests, such as imaging and lab work.
  • Medication education and management, including antiplatelets, anticoagulants, statins, and antihypertensives.
  • Quality stroke metrics (for example, patient education) and community health education.

What questions look like: A patient with new atrial fibrillation is being discharged after an ischemic stroke. The best teaching point involves anticoagulation, not aspirin alone.

How Should You Use the SCRN Blueprint to Build a Study Plan?

Use the item counts to decide where your time goes, then use your own results to fine-tune.

  1. Pick your testing window first. Windows and application deadlines are fixed, so work backward from the deadline you plan to meet.
  2. Take a mixed baseline. Answer a set of questions across all five domains before you start reviewing, so you know where you actually stand.
  3. Weight by item count and weakness. A weak score in Hyperacute or Acute Care (42 items each) costs more than a weak score in Post-acute Care (19 items). Start where a high count meets a low score.
  4. Map every miss to an outline line. Tag each missed question to a subtopic, such as “II.E Thrombolytic Therapy” or “V.D Medication Education”, to find patterns.
  5. Cover your blind spots. ED nurses often need more post-acute and prevention review. Rehab nurses often need more hyperacute review. Don’t skip a domain just because it is smaller.

What Official Resources Should You Use?

  • SCRN 2026 Candidate Handbook: The content outline, eligibility, testing windows, scoring, and policies in one place.
  • ABNN SCRN exam page: Fees, scheduling with PSI, and yearly pass statistics.

Frequently Asked Questions About the ABNN SCRN Exam

What is the passing score for the SCRN?
You need a scaled score of 200. ABNN converts your raw score to this scale, and the passing point is set by stroke nursing experts rather than by a fixed percentage.

Are all 170 questions scored?
No. 150 questions are scored, and 20 are unscored pretest items that ABNN is evaluating for future exams. You won’t know which is which.

How many times can I take the SCRN?
You can test once per testing window and no more than three times in 12 months. Each attempt requires a new application and the full fee.

How soon will I get my results?
You receive pass/fail results when you finish at the test center, or by email if you tested remotely. Your digital badge follows within 4 to 6 weeks.

How long is the SCRN valid?
Certification lasts five years and expires December 31 of the fifth year. You can renew by retaking the exam or by documenting stroke nursing practice hours and continuing education.
