Access Now: AORN COVID-19 Clinical Support


AORN strongly believes in lifelong learning and continuing education. These values are shared by the more than 35,000 perioperative nurses who hold the CNOR® and other perioperative nursing credentials like the CSSM®, CNS-CP® and CRNFA®.


More than 35,000 perioperative nurses currently hold the CNOR credential. Research shows that certified nurses have greater job satisfaction, and are more confident in their practice. Hospitals and institutions around the world support the CNOR program not only because it distinguishes them as an employer of choice, but also because they know a certified nursing workforce is correlated with decreases in negative patient outcomes.


The CRNFA certification program is for registered nurses working in an expanded role as first assistants who are interested in improving and validating their knowledge and skills and providing the highest quality care to patients. For those nurses who already hold the CNOR credential, when you earn your CRNFA credential, your CNOR credential is merged with your CRNFA credential. Candidates use the CRNFA credential to gain credibility and recognition from colleagues and patients, achieve their personal and professional goals, and enhance their career development.


The Certified Surgical Services Manager (CSSM) certification program is for perioperative leaders interested in validating their managerial knowledge and skills. CSSM certification validates the achievement of the baccalaureate-prepared manager who demonstrates current proficiency as an administrator in the perioperative (pre-, intra-, and post-operative) setting. CCI delivers the CSSM exam to recognize the important role managers have in directing staff, programs and budgets in delivering safe patient care. The purpose of the CSSM exam is to provide recognition for the important and distinct role of surgical services managers.


CCI offers the Clinical Nurse Specialist Perioperative Certification Exam (CNS-CP) for masters-prepared Clinical Nurse Specialists (CNS). Specialty certification helps bridge the gap between initial certification as an APRN and specialty practice. The CNS-CP credential validates perioperative competency at an advanced practice level, positions the CNS for future developments in advanced practice, and meets Consensus Model guidelines.
