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
- Research
To enter into the RDN field, you need a master’s degree in an area related to food, nutrition, and dietetics. Once you have earned the degree, completed the requisite internship, and passed the CDR exam, you will possess the knowledge required to be called an RDN.
According to the Bureau of Labor Statistics (BLS), RDNs earned an average salary of $74,770 as of May 2024. Entry-level professionals in this field earned about $61,260, while those with extensive experience earned $101,760 or more during this time. The BLS projects the number of jobs in this field to grow by 7.4 percent between 2023 and 2033, compared with an anticipated growth rate of 4 percent for all jobs in general.
The entry-level education eligibility requirement for RDNs is a master’s degree.
Accreditation for Registered Dietitian Nutritionist Degrees
Institutional Accreditation
No matter what college or university you choose 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 for these institutions are:
- WASC Senior College and University Commission (WSCUC)
- Southern Association of Colleges and Schools Commission on Colleges (SACSCOC)
- Northwest Commission on Colleges and Universities (NWCCU)
- New England Commission of Higher Education (NECHE)
- Middle States Commission on Higher Education (MSCHE)
- Higher Learning Commission (HLC)
- Accrediting Commission for Community and Junior Colleges of the Western Association of Schools and Colleges (ACCJC)
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:
- Transnational Association of Christian Schools and Colleges (TRACS)
- Accrediting Council for Independent Colleges and Schools (ACICS)
- Distance Education Accrediting Commission (DEAC)
- Accrediting Bureau of Health Education Schools (ABHES)
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
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
While the entry-level education eligibility requirement for RDNs is a master’s degree, earning a relevant ACEND-accredited bachelor’s degree on the way is a good idea.
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 an 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 that offers only 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.
