Registered Dietitian Nutritionists Requirements
Educational and professional requirements of Registered Dietitian Nutritionists
Registered Dietitian Nutritionists (RDNs) are food and nutrition experts who have met the following criteria to earn the RD credential:
- Completed a minimum of a master’s degree at a US accredited college/ university or foreign equivalent and course work accredited by the Accreditation Council for Education in Nutrition and Dietetics.
- Completed an ACEND accredited supervised practice program at health-care facility, community agency, or a foodservice corporation or combined with undergraduate and graduate studies. Typically, a practice program will run six to 12 months in length.
- Passed a national examination administered by the Commission on Dietetic Registration (CDR.) For more information regarding the examination, refer to CDR’s website at www.cdrnet.org.
- Completed continuing professional educational requirements to maintain registration.
The Henry Ford Hospital Dietetic Internship qualifies as an ACEND – accredited supervised practice program.
Some RDs hold additional certifications in specialized areas of practice. These are awarded through CDR, the credentialing agency for the Academy, and/or other medical and nutrition organizations and are recognized within the profession, but are not required. Some of the certifications include pediatric or renal nutrition, sports dietetics, nutrition support, and diabetes education.
In addition to RDN credentialing, many states have regulatory laws for dietitians and nutrition practitioners. Frequently these state requirements are met through the same education and training required to become an RDN.
Effective January 1, 2024, the Commission on Dietetic Registration (CDR) will require a minimum of a master’s degree to be eligible to take the credentialing exam to become a registered dietitian nutritionist (RDN). In order to be approved for registration examination eligibility with a bachelor’s degree, an individual must meet all eligibility requirements and be submitted into CDR's Registration Eligibility Processing System (REPS) before 12:00 midnight Central Time, December 31, 2023. For more information about this requirement visit CDR's website: https://www.cdrnet.org/graduatedegree. In addition, CDR requires that individuals complete coursework and supervised practice in program(s) accredited by the Accreditation Council for Education in Nutrition and Dietetics (ACEND). Graduates who successfully complete the ACEND-accredited Dietetic Internship program at Henry Ford Hospital are eligible to apply to take the CDR credentialing exam to become an RDN.
In most states, graduates also must obtain licensure or certification to practice. Currently 48 states, Puerto Rico and the District of Columbia have statutory provisions regulating the dietetics profession or associated titles such as "dietitian" and "nutritionist." As of January 2020, Michigan and Arizona are the only two states that do not have licensure.
