About the CNRN Exam
The CNRN Examination is a generalist examination and is not intended to emphasize any particular level of care or any particular developmental level.
Format and Contents
The examination, conducted in a computer-based testing facility, consists of approximately 220 multiple-choice items with a total testing time of 4 hours. Twenty of the 220 items are pretest items, which are not scored.
The examination may include additional items that are being tested for future use.
The examination is based on periodic role delineation studies that identify the knowledge and experiences required of a practicing neuroscience nurse. The most recent role delineation study was completed in summer 2014. View the CNRN Candidate Handbook for detailed exam information, including the content outline.

All documentation must be received within 21 days of the request.
