Credentialing Exam Criteria

Effective January 1, 2024, the Commission on Dietetic Registration (CDR) will require a minimum of a master's degree to be eligible to take the credentialing exam to become a registered dietitian nutritionist (RDN). In order to be approved for registration examination eligibility with a bachelor's degree, an individual must meet all eligibility requirements and be submitted into CDR's Registration Eligibility Processing System (REPS) before midnight Central Time, December 31, 2023. For more information about this requirement visit CDR's website.

In addition, CDR requires that individuals complete coursework and supervised practice in program(s) accredited by the Accreditation Council for Education in Nutrition and Dietetics (ACEND). Graduates who successfully complete the ACEND-accredited Masters of Science/Dietetic Internship program at Northern Illinois University are eligible to apply to take the CDR credentialing exam to become an RDN.
