Is the CNRN program accredited?
The CNRN certification program is accredited by the Accreditation Board for Specialty Nursing Certification (ABSNC), the only nationally recognized accrediting body for specialty nursing certification programs. ABSNC accreditation is a peer-review mechanism that allows nursing certification organizations to obtain accreditation by demonstrating compliance with the highest quality standards in the industry. Read more about the impact of specialty nursing certification as shown in an ABNS Importance of Specialty Board Nursing Certifications report.
What is the format of the CNRN exam?
The CNRN exam is conducted in a computer-based testing facility and consists of 220 multiple-choice items with a total testing time of 4 hours. Twenty of the 220 items are pre-test items that are being tested for future use—these questions are not scored and will not impact your final exam results.
Note: the CNRN credential is a marker of your knowledge of neuroscience nursing fundamentals. As a result, the CNRN exam is a generalist exam and is not intended to emphasize any particular level of care or developmental level.

How does ABNN determine the CNRN exam content outline?
The CNRN content outline is based on periodic job analyses (JA) or role delineation studies that identify the knowledge and experiences required of a practicing neuroscience nurse. In order to maintain accreditation, job analysis studies are required every 5 years to ensure that the content outline, domains, and tasks are updated based on current practice.
The most recent job analysis study was completed in summer 2019. View the 2025 CNRN Candidate Handbook for more information and to view the content outline and step-by-step instructions on how to select your exam date.
How are items (exam questions) developed for the exams?
A group of CNRN certified subject matter experts (SMEs) are trained by ABNN and PSI to write and review items (questions) each year, with special instruction in reducing potential sources of bias and sensitivity. ABNN focuses on selecting SMEs who are reflective of the candidate pool in all aspects including geographic location, years of experience, educational background, ethnicity, gender, practice setting, and more. These items are then reviewed, revised, and approved for pre-testing by the Test Development Committee. All items for an exam form are pre-tested prior to being used as scoreable items. At conclusion of the pre-testing process, the item's performance is analyzed to determine whether it meets the criteria to be included as a scoreable item. The items are also repeatedly reviewed throughout the exam development process to ensure it is still reflective of current practice.
How is the passing score determined?
The passing score is established by a systematic criterion-referenced procedure that employs the judgment of neuroscience nursing experts from around the country as well as the assistance of professional psychometricians from PSI. With this process, the raw score (i.e., number of correct answers) required to pass an examination form is established; that score relates to the number of correct answers that a minimally competent candidate would be expected to provide. The final determination of the passing score is made by the ABNN Board of Trustees.
My CNRN credential is about to expire. How do I recertify?
You can recertify as a CNRN by earning CE credits prior to your certification expiration date or by retaking the CNRN exam. You will not create a new log-in to apply for recertification. Please call ABNN’s customer service at 847.375.4733 if you do not have your password.
