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.
