Educational and professional requirements

Registered Dietitians (RDs) or Registered Dietitian Nutritionists (RDNs) are food and nutrition experts who have met the following criteria and earned the RD or RDN credential:

  • Completed a minimum of a bachelor’s degree at a U.S. regionally accredited university or college or foreign equivalent, and coursework through an Accreditation Council for Education in Dietetics (ACEND) accredited Didactic Program in Dietetics (DPD) or Coordinated Program in Dietetics (CP).
  • Complete 1200 hours of supervised practice through an ACEND accredited Dietetic Internship, Coordinated Program in Dietetics or an Individualized Supervised Practice Pathway (ISPP) offered through an ACEND accredited program.
  • Passed a national examination administered by the Commission on Dietetic Registration (CDR). For more information regarding the examination, refer to CDR’s website at In order to maintain the credential, an RD or RDN must complete continuing professional educational requirements.

Some RDs or RDNs hold additional certifications in specialized areas of practice. These are awarded through CDR, the credentialing agency for the Academy, and/or through other medical and nutrition organizations. These certifications are recognized within the profession, but not required. Some of the certifications include pediatric or renal nutrition, sports dietetics, oncology, gerontological, nutrition support and diabetes education.

In addition, many states have regulatory laws (i.e. licensure) for food and nutrition practitioners. All states accept the RD or RDN credential for state licensure purposes.

Dietetics students study a variety of subjects, including food and nutrition sciences, biochemistry, physiology, microbiology, anatomy, chemistry, foodservice systems, business, pharmacology, culinary arts, behavioral social sciences and communication.
