The Commission on Dietetic Registration administers rigorous valid and reliable credentialing processes to protect the public and meet the needs of CDR credentialed practitioners, employers and consumers.
Nutrition and dietetics credentialing protects and improves the health of the public and supports practitioner competence, quality practice, lifelong learning and career advancement.
The Commission on Dietetic Registration (CDR) has sole and independent authority in all matters pertaining to certification, including but not limited to standard setting, establishment of fees, finances and administration.
More than 89,000 dietitians and dietetic technicians across the country and the world have taken CDR exams over the past several decades. CDR currently awards eight separate and distinct credentials: Registered Dietitian Nutritionist (RDN™) or Registered Dietitian (RD™)*; Nutrition and Dietetics Technician, Registered (NDTR™) or Dietetic Technician, Registered (DTR™)**; Board Certified Specialist in Renal Nutrition (CSR); and Board Certified Specialist in Pediatric Nutrition (CSP), Board Certified Specialist in Sports Dietetics (CSSD), Board Certified Specialist in Gerontological Nutrition (CSG), Board Certified Specialist in Oncology Nutrition (CSO) and Advanced Practice Certification in Clinical Nutrition (RDN-AP or RD-AP)***.
The Commission's RD/DTR certification programs are fully accredited by the National Commission for Certifying Agencies (NCCA), the accrediting arm of the Institute for Credentialing Excellence based in Washington, D.C. This accreditation reflects achievement of the highest standards of professional credentialing.
The Commission consists of 11 members. Nine members are elected for a three-year term by credentialed practitioners, RDNs or RDs and NDTRs or DTRs. These elected members include 7 RDNs or RDs, 1 RDN or RD Specialist, and 1 NDTR or DTR. A newly credentialed RDN or RD had been appointed by the Commission for a one-year term. In addition, a public representative is appointed by Commission members for up to a five year term and has full rights and privileges.
The Chair and Vice-Chair are elected by the Commission for a one-year term June 1 - May 31.
