The purpose of the Commission, as the credentialing agency and organization unit of the Academy, is to serve the public by establishing and enforcing standards for certification, recertification and the Code of Ethics and by issuing credentials to individuals who meet these standards. The Academy owns the credentials; however CDR has independent authority in matters pertaining to certification, including standard setting, establishment of certification fees and administering credentialing programs. CDR maintains a registry of over 100,000 credentialed dietetics practitioners.
Credentialed practitioners, RDNs*, RDs*, NDTRs** and DTRs**, elect Commission members for three-year terms. Since 1990, an elected DTR** member has served on the Commission. A Board Certified Specialist was also included on CDR since the implementation of the specialty certification programs. An Advanced Practice in Clinical Nutrition representative has been appointed for the 2016-2017 program year. A public representative has held a position on CDR since 1984 and has full rights and privileges. Beginning in June 2006, a newly credentialed registered dietitian serves on the Commission for a two-year term. In all, the Commission currently consists of 12 members, 9 who are RDNs* or RDs*, 1 of whom is newly credentialed, 1 NDTR** or DTR** and 1 public representative. The Chair and Vice-Chair are elected by the Commission for a one-year term June 1 - May 31.
