Preparing registered dietitians

The mission of the OSU Department of Nutritional Sciences Dietetic Internship Program is to advance health and quality of life of individuals and communities by preparing entry-level registered dietitians for competent practice through education, discovery and application of scientific knowledge. We are a combined program, which means students earn a master’s degree while completing their internship.

Nationally accredited

Our program has been granted accreditation by the Accreditation Council for Education in Nutrition and Dietetics (ACEND) of the Academy of Nutrition and Dietetics, 120 South Riverside Plaza, Suite 2190, Chicago, IL, 60606-6995, 312-899-0040 ext. 5400, until 2028 to accept up to 24 interns per year.
*Please note that program outcomes data are available upon request.

Applying to the program

Application to the OSU Dietetic Internship Program is a four-part process, which includes completing an application using the Dietetic Internship Centralized Application System (DICAS) and being accepted to an approved master’s degree program.

Completion Requirements

Upon successful completion of both the master’s degree and 1000 hours (temporary COVID requirement, normally 1200 hours) of supervised practice required by the Dietetic Internship, interns are eligible to sit for the examination to become a registered dietitian nutritionist (RDN), which is administered by the Commission on Dietetic Registration (CDR) of the Academy of Nutrition and Dietetics. Once registered, the individuals eligible to apply for licensure in their practice state, if applicable.

Eligibility Update

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 12:00 midnight Central Time, December 31, 2023.
