State Requirements for Nutrition and Dietitian Fields

Registered Dietitian Nutritionist Degree

Per the Academy of Nutrition and Dietetics, Registered Dietitian Nutritionists (RDNs) are experts in food and nutrition who have met certain criteria. This includes completing at least an approved bachelor’s degree, participating in an approved supervised practice program, and passing a national examination given by the Commission on Dietetic Registration (CDR). While RDNs may hold certification in other, specialized areas of practice, the RDN is the credential that is nationally recognized and will help you to find employment in a wide variety of settings, ranging from hospitals and health care facilities, sports and wellness programs, businesses and industries related to food and nutrition, private practice, community health, university medical centers, and research.

To enter into the RDN field, you need a bachelor’s degree in an area related to food, nutrition and dietetics. Once you have earned the degree, complete the requisite internship and pass the CDR exam, you will possess the knowledge required to be called an RDN. According to the US Bureau of Labor Statistics, as of 2019, RDNs working in the US earn an average salary of $61,270 per year, translating to $29.46 hourly. With a projected employment outlook of jobs increasing by 11 percent from 2018 to 2028, the RDN field is looking quite bright.
Note: as of 2024, the Commission on Dietetic Registration is changing the entry-level eligibility requirements for RDNs from a bachelor’s to a master’s degree.

Accreditation for Registered Dietitian Nutritionist Degrees

Institutional Accreditation
No matter what college or university you choose in which to pursue your RDN degree, that institution must be accredited by an accrediting organization that Is recognized by the Council for Higher Education Accreditation (CHEA) and the US Department of Education (USDE). The most common CHEA-recognized regional accrediting organizations (updated May 2020) for these institutions are:

In addition to accreditation by regional organizations, institutions may be accredited by other types of organizations, including, but not limited to, career and technical and faith-based accrediting organizations. This accreditation counts in lieu of the regional accreditation listed above. Some examples include:

Programmatic Accreditation

The Accreditation Council for Education in Nutrition and Dietetics (ACEND) is the accrediting agency of the Academy of Nutrition and Dietetics. Any RDN degree program you choose should hold ACEND accreditation. This type of accreditation is the “gold standard” for RDNs nationwide.

Undergraduate Degrees for Registered Dietitian Nutritionists

As mentioned above, you can currently enter into the RDN profession with a bachelor’s degree. The bachelor’s degree program you choose should hold accreditation through ACEND. There are two types of ACEND-accredited bachelor’s degree programs for RDNs:

  • CP: A Coordinated Program in Dietetics (CP) is a comprehensive RDN educational program that offers the class work and dietetic internship together. After completing a CP, you will be qualified to take the Commission on Dietetic Registration (CDR) examination to become a RDN. ACEND maintains a database of CP in dietetics programs by state here.
  • DPD: A didactic program in dietetics (DPD) is an RDN educational program offering just the classroom work portion of the degree program. ACEND maintains a database of DPD programs by state here.
    • After completing a DPD, you must then complete a Dietetic Internship (DI) in order to be eligible to take the CDR exam and become an RDN. You can find an ACEND-accredited Dietetic Internship here.
