Becoming a Registered Dietitian Nutritionist (RDN)

Registered Dietitian Nutritionists (RDNs) are food and nutrition experts who have met the Commission on Dietetic Registration’s (CDR) criteria to earn the RDN credential. They work in a wide variety of employment settings, including health care, business and industry, community/public health, education, research, government agencies and private practice. According to the U.S. Bureau of Labor Statistics, the job outlook for dietitians is expected to increase by 15 percent, which is must faster than average.

Three steps to becoming a Registered Dietitian or Registered Dietitian Nutritionist through OSU:

  1. Complete the undergraduate OSU Didactic Program in Dietetics (DPD). This step requires graduation with a bachelor’s degree* and completion of the dietetics curriculum from an Accreditation Council for Education in Nutrition and Dietetics- (ACEND) program, a designation held by the OSU DPD. *Effective January 1, 2024, new RDNs will be required to have a master’s degree (in any field).
  2. Complete the ACEND-accredited OSU Dietetic Internship Program
  3. Pass the national registration exam administered by the CDR of the Academy of Nutrition and Dietetics. After registration RDNs are required to complete 75 clock hours of continuing professional education over five year periods in order to maintain registration. Some states require licensure to practice as a dietitian (Oklahoma does).
