The Certified Bariatric Nurse (CBN) Program is designed to assess the professional competence of practitioners of Bariatric Nursing.


Our vision is to provide the premier credential to professional nurses caring for the the morbidly obese and bariatric surgical patient.


The RN Certification Committee and the Certification Advisory Committee of the American Society for Metabolic and Bariatric Surgery are dedicated to enhancing and promoting the specialty of bariatric nursing care.

In order for candidates to sit for the CBN examination they must satisfy the following eligibility criteria, including compliance with the ASMBS standards of conduct:

In addition, the examination will only be offered in the English language.
