RD Exam Preparation

All exam candidates are required to review the Handbook for Candidates before making their testing appointment. The handbook contains important information regarding scheduling procedures, examination content, and reporting of results. 

The Commission on Dietetic Registration (CDR) publishes the Study Guide for the Registration Examination for Dietitians. The study guide includes:

  • a comprehensive study outline based on the examination content specifications implemented January 1, 2017;
  • suggested study references;
  • study tips;
  • a print and online version of the practice examination; and 
  • two single use vouchers to use when accessing the online practice examination. 

The study guide can be purchased from the Academy of Nutrition and Dietetics’ online store. 

CDR does not endorse any particular examination preparation program or offering. We encourage prospective credentialed practitioners to use a variety of resources that reflect their learning styles and needs. Purchasing a certification preparation product is NOT required and CDR does not guarantee that an individual will pass based on the purchase of a certification preparation product.
