The Competency and Credentialing Institute (CCI) developed the CNOR exam with Prometric, a subsidiary of Educational Testing Service. Prometric offers the computer-based exam throughout the United States and Canada. The test includes 200 multiple-choice questions that must be completed within four hours.

Individual versions of the CNOR exam may vary in difficulty, but this is taken into account during the scoring process. About 90% of the CNOR questions concern patient care management, and the remaining 10% focus on management of operating room materials, personnel, and services.

CNOR Exam Overview

Typical topics include asepsis maintenance; healthy workplace practices; instrument selection and processing; patient freedom from harm; sponges, sharps, and instruments; patient assessment and diagnosis; patient positioning; pharmacology (including anesthetics); education and support of patient and family; ambulatory surgery; special populations; and legal, regulatory, legislative, and professional issues.

After applying for and scheduling the CNOR test, Prometric sends an authorization to test. Registrants receive an authorization number as well as the web address and telephone number for scheduling the CNOR exam. When taking the exam, registrants must present two forms of identification.

Test-takers should try to answer all questions and leave nothing blank on the CNOR exam. On the computer, users can mark certain questions and return to them later during the exam. People who are not familiar with computerized tests may take a tutorial on a computer before taking the actual exam.

Critical test results become available immediately after the CNOR exam. Users will be informed immediately if they have passed the test, although they will not receive any scoring details. Additional scoring information will be included with the official, mailed notification that the user passed the CNOR exam.

Persons who fail the exam receive more information when the exams are scored. This includes a look at how close they came to passing and information about what areas they need to improve.
