Schedule and Take the CNOR Exam

Once your application has been approved, you may locate a testing center near you and schedule an exam time. Be sure to bring your ID documentation to the testing center and to follow all testing center rules. You will have 3 hours and 45 minutes to complete the 200 question exam.  

Once CCI has processed your application and determined that you have met all eligibility requirements, you will be notified to schedule your testing date and location. CCI works with Prometric, a professional testing service, to administer the CNOR exam. Testing is available Monday through Saturday, except holidays, at hundreds of locations nationwide.

To locate the testing center closest to you, visit Competency and Credentialing Institute Testing and select "Locate a Test Center." If you are testing outside of the US, Prometric will make reasonable efforts to find a test center within-five hundred miles of your requested location.

You will have 3 hours and 45 minutes to complete the 200 multiple choice questions on the exam.  Plan on answering one question per minute.  The questions test your ability to apply knowledge and skills to perioperative practice. The CNOR exam is a computer-based test that requires you to answer all 200 questions. The format of the exam does not require previous computer experience.

Learn about the ID requirements and see a list of items that are prohibited from all testing centers.

Get Your Results 
You will receive your CNOR results at the conclusion of the exam.  The CNOR exam is graded on a pass/fail basis. If you pass the exam, CCI will email your official CNOR certificate within 7-10 days.

If you are not successful in passing the CNOR exam, you will receive a Failed Score Report at the testing center.  This report details the subject areas in which you are considered competent and those which need improvement. Use this information to identify the subject areas where you need additional preparation and consider when you would like to re-take the exam.

To retake the exam, you may apply any time after the end of your testing window.  The retake fee is the same as the regular application fee.
