Certified Perioperative Nurse

The Certified Perioperative Nurse (CNOR®) credential is the only accredited certification for perioperative registered nurses. CNOR certification assesses the knowledge and skills of a perioperative nurse with a minimum of two years of clinical practice. Held by more than 40,000 nurses internationally, earning the CNOR is a mark of distinction and demonstrates a commitment to upholding the highest standards in patient safety.

Certification Update

CCI’s 2024 Job Task Analysis results have been adopted, streamlining CNOR® and CFPN® exams from seven to six consolidated competency areas launching in 2027. This evidence-based evolution maintains rigorous standards while improving assessment efficiency.

  • Scheduling your exam is no longer tied to fixed testing windows
  • 12-month eligibility period begins from date of application approval
  • First exam attempt is included with the application fee

Notice: First attempt must be scheduled and taken within 90 days of approval. Failure to test forfeits the attempt and associated fees but does not end your eligibility.

EXAM RETAKES

Streamlined Retake Process

  • Purchase and schedule retakes directly through your CCI account
  • No new application required within your 12-month eligibility period

Remember: There is a required 30-day minimum waiting period between each exam attempt and a retake fee must be paid for each attempt.

Candidates are strongly encouraged to review eligibility requirements and prepare to test within the initial 90-day window to maximize their testing opportunity.

A percentage of applications will be randomly selected for audit. If you are selected, you will be notified upon submission of your application. Applicants chosen for audit will be required to electronically submit copies of specific documentation, as outlined in the candidate handbook.
