CNRN Exam Registration

To register for the exam, you must submit an online application at the ABNN website. Your application must include the applicable examination fee, whether you pay online or via check. The examination fee is $300 for AANN members and $400 for non-members, and paying by check incurs an additional $25 fee.

Once your application is approved, you will receive confirmation and instructions on how to schedule an examination appointment with PSI.

Test Day

Regardless of your exam-taking method, you will be asked on test day to present two current and valid forms of identification, one of which must contain your photograph. Both forms of identification must have your signature for verification.

In-person Testing

On test day, you should arrive 15-30 minutes early for your scheduled appointment time. If you are more than 15 minutes late, you will not be admitted, and your test will be canceled.

Before the exam begins, you must secure any personal items (including your phone, wallet, and keys) in a provided locker. A pencil and a sheet of paper are provided, so there is no need to bring those items with you to the testing center.

During the exam, you can take a break whenever you need to, but the timer will keep going during your break.

Live Remote Proctoring

On test day, you should log in to your account 10-15 minutes before your examination appointment. Once you are logged in, a proctor will ask you to scan your testing space with your webcam to ensure your testing area is clear of books, notes, and electronic devices. You are allowed a pencil and a blank sheet of paper on your desk; all other items need to be removed from the area.

The launch button for the exam is enabled when the exam and proctor are ready.

How the CNRN Exam is Scored

Your CNRN score is determined by using a scaled scoring system. This system converts your raw score (the number of questions you answered correctly) into a numerical scaled score. You must have a final scaled score of at least 200 to pass the exam.

If you pass the exam, you will receive your certificate packet by mail within 4 to 6 weeks after testing.
