Becoming an RDN

How the internship fits into credentialing process

Those who have at least a bachelor’s degree and a Verification Statement from a Didactic Program in Dietetics (DPD) Program are eligible to apply for an internship.

Those who successfully complete the ISU Dietetics Internship Program will receive the DI Verification Statement which establishes eligibility to sit for the national standardized exam administered by the Commission on Dietetic Registration (CDR).

Those who successfully pass the exam may use the registered dietitian nutritionist (RDN) credential. Once RDN credential is obtained, state licensure may be applied for where applicable.
