CDA Information

Mission Statement

The Commission on Dietetic Registration (CDR) administers valid, reliable, and rigorous credentialing processes to protect the public and meet the needs of CDR credentialed practitioners, employers, and consumers.

Vision Statement

Nutrition and dietetics credentialing protects and improves the health of the public and supports practitioner competence, lifelong learning and career advancement. CDR credentialed practitioners are recognized and respected as the food and nutrition leaders.


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.

The Commission’s RD and 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. To learn more about CDR, visit the CDR website.

If you have received an Authorization to Test email from Pearson VUE, you are now eligible to take the credentialing examination for dietitians or dietetic technicians.
