CNOR Certification Exam 2026

CNOR Meaning

The CNOR credential isn’t for nurses just starting out in the perioperative field; it’s typically earned by OR nurses who have already accumulated a certain level of skill and experience. Having the certification allows them to succinctly demonstrate that fact.

In addition to passing the exam, nurses must maintain an unrestricted RN license in the state where they practice and currently work full- or part-time in a perioperative clinical setting (or nursing education, administration, or research). They also must have at least two years of experience in the OR, including more than 1,200 hours of intra-operative time.

AORN offers a variety of resources to help nurses prepare for the CNOR exam. For example, the article "Surgical specimen management errors in the preanalytic phase: perioperative nursing implications"44 provides an overview of different types of specimen management errors and discusses how these errors can affect patients. It also discusses ways that perioperative nurses can prevent these errors. The CNOR certification is a significant achievement in the nursing profession and is a mark of quality care for patients.
