The supervised practice experience may be completed after passing the Certification Examination for Nutrition Specialists, however the candidate will not be awarded, and may not use, the CNS credential until the supervised experience is completed and approved.

Examination Requirement

The candidate must achieve a passing score on the Certification Examination for Nutrition Specialists, offered twice a year, typically in the spring and fall.

The examination is designed to test the knowledge and skills acquired by those who have successfully completed both the academic and experiential criteria of the CNS and CNS-S. While we may approve those who have not yet completed the experience requirement to sit for the examination, evidence shows that those with experience perform better than those without.

The examination contains 200 multiple-choice, single answer questions. It covers a broad spectrum of basic and applied nutritional science based on an explicit set of competencies. These have been determined through a job analysis study conducted on practitioners.

The competencies are grouped into domains, subdomains and tasks. As the examination may only assess knowledge pertaining to these competency statements, they serve as the outline, or blueprint for the examination.

See How to Prepare for the Examination and the Examination Content Outline.

Recertification Requirements

To maintain the CNS credential, all CNS certificants must recertify every five years and document 75 Continuing Education (CE) credits. Learn more about recertification.
