Are you due to recertify your Certified Nutrition Support Clinician (CNSC) credential? You’re not alone! The CNSC exam requires recertification every 5 years, and staying current offers serious advantages in today’s competitive healthcare landscape.
In this post, I cover everything you need to know about CNSC recertification, including recent exam changes, and how you can prepare with confidence.
Why Recertify Your CNSC Credential?
Letting your CNSC certification lapse is always an option—but keeping it active comes with major benefits:
Continued use of the CNSC credential
Increased visibility and respect in clinical nutrition and dietetics
Improved job competitiveness in a saturated healthcare market
Higher earning potential (Yes—CNSC-credentialed dietitians earn more)
Earn 75 Continuing Professional Education (CPE) credits
⭐ While the Commission on Dietetic Registration (CDR) has reduced CPE credit values for many credentials, the CNSC remains at 75 CPEs
CNSC Exam Recertification: What’s Changed?
If you last took the CNSC exam five years ago, you might be surprised by how much it’s evolved:
Pass rates have dropped. In 2020, pass rates were above 90%. Since then, the National Board of Nutrition Support Certification (NBNSC) made the exam more challenging to maintain its credibility
NBNSC hasn’t released pass rates since Spring 2022, making it harder to gauge current exam trends
Students and professionals agree: the 2024 exam was significantly harder than in previous years
