CBN 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.

  • 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.
  • Complete a minimum of 24 months (within the preceding 4 years) of nursing care of morbidly obese and bariatric surgery patients, predominately in the metabolic and bariatric surgery process (i.e., pre-operative, peri-operative or post operative/follow up care).
    • 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.
