How to Become a Dietitian

1. Earn a Bachelor's Degree (4 Years)

A four-year college degree with a major in dietetics is required to become a registered dietitian (RD). There are two types of programs available:

  • A didactic program involves classroom instruction during college, followed by a field internship for one-year
  • A coordinated program in dietetics requires both classroom instruction and 900 hours of supervised practice.

Before enrolling, ensure that the program is accredited by the Accreditation Council for Education in Nutrition and Dietetics (ACEND).
