Commission on Dietetic Registration

The Commission on Dietetic Registration (CDR) is the credentialing body responsible for certifying and maintaining the professional credentials of dietitians and nutritionists in the United States. It establishes the standards for education, experience, and ongoing professional development needed to become a registered dietitian (RD) or registered dietitian nutritionist (RDN). By ensuring practitioners meet these standards, CDR helps guarantee that individuals providing nutrition guidance are qualified and knowledgeable, supporting public health and well-being through reliable and competent nutritional care.
