The Certified Neuroscience Registered Nurse (CNRN) exam is designed for registered nurses who specialize in neuroscience nursing. This guide covers the current exam format, eligibility requirements, content outline, costs, scoring, testing process, and study resources to help you prepare.
Exam Background and Purpose
The CNRN certification is offered by the American Board of Neuroscience Nursing (ABNN). It is intended for registered nurses who want to demonstrate specialized knowledge and experience in neuroscience nursing.
The examination is a general neuroscience nursing exam rather than a test focused on one particular patient population or level of care. Candidates are expected to understand neurological conditions as well as the nursing interventions, safety practices, patient management, and multidisciplinary care associated with them.
Important: The current CNRN exam outline is based on ABNN’s 2024 job analysis and took effect beginning with the July 2025 testing window. Older study materials that organize the exam only by Trauma, Cerebrovascular, Tumors, Infection and Immune Complications, Neurodevelopmental Conditions, and Neurological Disorders use the previous blueprint.
CNRN Eligibility
To take the CNRN exam, you must meet both a nursing-license requirement and a neuroscience nursing experience requirement.
Registered Nurse License: You must hold a current, unrestricted RN license that remains valid through your examination date. This includes qualifying licenses in the United States, Canada, and eligible U.S. territories.
Neuroscience Nursing Experience: You must have completed at least one year of full-time experience, or 2,080 hours, in direct or indirect neuroscience nursing practice during the three years before you apply.
International Candidates: Nurses from other countries may also be considered if they hold a comparable nursing license, can read and understand English, and have their licensure evaluated for equivalency by an accepted credential-evaluation organization before applying.
Qualifying neuroscience experience is not limited to bedside nursing. Experience as a consultant, researcher, administrator, educator, or clinical supervisor may also qualify if it meets ABNN requirements.
CNRN Exam Format
The 20 pretest questions are being evaluated for possible use on future versions of the CNRN exam and do not count toward your score. They are mixed in with the scored questions, so you will not know which questions are unscored.
What Is on the CNRN Exam?
The current CNRN blueprint contains three major content domains. The number of questions below refers to the 200 scored questions on the exam.
| Content Domain | Questions / Weight |
|---|---|
| Anatomy, Physiology, Pathophysiology, and Diagnosis | 91 / 45.5% |
| Patient Management | 76 / 38% |
| Multidisciplinary Care | 33 / 16.5% |
Anatomy, Physiology, Pathophysiology, and Diagnosis
This is the largest domain on the CNRN exam, accounting for 91 scored questions. It covers the neurological conditions, underlying disease processes, anatomy, physiology, and diagnostic concepts a neuroscience nurse needs to understand.
Major areas include:
Trauma: traumatic brain injury, hematoma and hemorrhage, spinal cord injury, and skull and spinal fractures
Cerebrovascular conditions: ischemic and hemorrhagic stroke, transient ischemic attack, vascular anomalies, cerebral venous sinus thrombosis, anoxic injury, and stroke mimics
Neuro-oncology: brain tumors, spinal cord tumors, and neuro-endocrine disorders
Infection and immune complications: meningitis, encephalitis, abscesses, neuromuscular disorders, encephalopathies, and neurodegenerative disorders
Neurodevelopmental conditions: cranial and cerebral defects, Chiari malformation, hydrocephalus, and congenital brain and spinal cord abnormalities
Neurological disorders: seizures, headaches and migraines, dementia, movement disorders, degenerative spine disease, hydrocephalus, and peripheral nerve disorders
Patient Management
This domain contains 76 scored questions and focuses on the nursing care and interventions used to manage patients with neurological conditions.
Physiological Interventions
Activity and self-care, bowel and bladder management, nutrition, metabolic management, medications, neurological assessment, surgical and procedural treatment, respiratory and airway management, thermoregulation, and cardiovascular management.
Behavioral Interventions
Patient behavior, psychosocial considerations, chemical dependency, pain, coping, and self-care resources.
Safety Interventions
Neurological decline, delirium, abuse recognition, environmental safety, fall and seizure precautions, infection prevention, and restraints.
Multidisciplinary Care
The remaining 33 scored questions measure knowledge related to quality of life and health care management.
Quality of Life
Comfort, support systems, cultural and socioeconomic considerations, social determinants of health, rehabilitation, continuing care, palliative care, hospice, end-of-life care, and organ donation.
Health Care Management
Patient and caregiver education, multidisciplinary collaboration, quality improvement, outcome evaluation, scope of practice, delegation, ethics, evidence-based standards, and regulations.
CNRN Exam Cost
The amount you pay depends on whether you are an American Association of Neuroscience Nurses (AANN) member and whether you pay electronically or by check.
All CNRN applications are completed online through ABNN, even if you choose to pay by check or money order.
CNRN Testing Windows
The CNRN exam is not offered continuously throughout the year. ABNN schedules the exam during specific testing windows.
For 2026, the CNRN testing windows are:
Registration deadlines and testing windows can change from year to year, so candidates should verify the current schedule before submitting an application.
Scheduling and Taking the Exam
After your application is accepted and you receive confirmation that you are eligible to test, you can schedule your examination through PSI.
You can take the CNRN exam using either of the following methods:
PSI Test Center: Take the computer-based examination in person at an available PSI testing location.
Live Remote Proctoring: Take the examination from home or another approved private location while being monitored by a PSI proctor.
If you choose remote testing, you are responsible for making sure your computer, webcam, microphone, internet connection, and testing room meet PSI’s requirements.
What to Know Before Test Day
Review your PSI appointment information before the exam.
Make sure your identification meets the current testing requirements.
If testing remotely, complete PSI’s computer and system checks before test day.
Answer every question because the 20 unscored pretest questions are not identified.
How Is the CNRN Exam Scored?
Your score is based on the 200 scored questions. ABNN converts your raw score, or the number of scored questions you answer correctly, to a scaled score.
The raw score required to pass a particular exam form is converted to a scaled score of 200. Because different versions of the examination can vary slightly in difficulty, there is not one fixed number of raw questions that you must answer correctly on every version of the test.
Your pass/fail result is released at the close of the examination, and a copy of your score report can be accessed through your PSI Test Taker Portal.
Can You Retake the CNRN Exam?
Yes. Candidates who do not pass may apply for a later examination window.
You may take the CNRN exam once per examination window and no more than three times within a 12-month period. Each additional attempt requires a new application and the full examination fee.
How Long Does CNRN Certification Last?
CNRN certification is valid for five years. The certification expires on December 31 of the fifth year after certification.
To maintain the credential, you must complete the applicable ABNN recertification requirements. CNRNs may recertify by completing the required continuing education and neuroscience nursing practice requirements or by retaking the certification examination.
How Can I Prepare for the CNRN Exam?
Start your preparation with the current three-domain CNRN blueprint rather than an older outline organized only by neurological condition. Nearly half of the scored exam is devoted to Anatomy, Physiology, Pathophysiology, and Diagnosis, but more than half of the scored questions collectively fall under Patient Management and Multidisciplinary Care.
That means successful preparation should go beyond memorizing neurological disorders. You should also be comfortable deciding how patients should be assessed, managed, protected from complications, educated, and supported throughout their care.
CNRN Study Checklist
Use study materials based on the current three-domain CNRN blueprint.
Review neurological anatomy, physiology, disease processes, and diagnostic findings.
Practice applying nursing interventions to realistic patient scenarios.
Review safety, neurological assessment, medication, airway, cardiovascular, and behavioral management concepts.
Study patient education, rehabilitation, palliative care, interdisciplinary collaboration, delegation, and professional practice.
Use timed practice questions so you become comfortable completing 220 questions within four hours.
