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 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.

CBN Eligibility

Eligibility Requirements for Certification

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:

  1. Be currently licensed as a professional nurse (RN) in one of the 50 United States, the District of Columbia or Puerto Rico. A valid license number MUST be entered when applying online.

    • International nurses are eligible to sit for the CBN examination. Acceptable international nurse licensure will be determined on an individual basis by the ASMBS. It is important for international nurses to understand that the examination is based on a practice analysis of nursing care of morbidly obese and bariatric surgical patients in the United States of America. In addition, the examination will only be offered in the English language.
  2. Complete a minimum of 24 months (within the preceding four years) of nursing care of morbidly obese and bariatric surgery patients, predominately in the bariatric surgery process (i.e., pre-operative, peri-operative or post operative/follow up care).

    • An RN who serves as a Metabolic & Bariatric Surgical Clinical Reviewer (MBSCR) at an accredited Metabolic & Bariatric Surgery Accredited Center through the Metabolic & Bariatric Surgery Accreditation & Quality Improvement Program (MBSAQIP) is eligible to take the examination, assuming they meet all other requirements.
