Nutrition Exam

NOTE:  Before applying to take this exam, you must contact the CBCN at to determine eligibility.

What Is The Nutrition Exam?

Certification in clinical nutrition provides formal recognition of nutrition knowledge by Chiropractic Diplomates. It is a voluntary certification, by examination, focusing on individual competence in this specialized practice area. States vary as to whether and how a Diplomate may hold themselves out as a specialist so the Chiropractic Board of Clinical Nutrition (CBCN) recommends each Diplomate check with their licensing board on this issue.

The 200-question written examination for the CBCN is developed jointly with the National Board of Chiropractic Examiners (NBCE) and administered electronically by various testing centers across the country. Questions concerning the content of the examination should be directed to CBCN at:
