Frequently Asked Questions
What is the DTR exam pass rate?
CDR does not publish one consolidated DTR/NDTR first-time pass-rate percentage. It reports some results by eligibility pathway, so those figures should not be presented as one overall candidate pass rate.
How many questions are on the DTR exam?
The CDR DTR exam is computer-adaptive with a minimum of 110 questions to score and a maximum of 130 questions. The exam continues until a reliable pass/fail determination can be made.
What is the DTR exam format?
The exam is computer-adaptive testing (CAT) with multiple-choice questions. You have 3 hours to complete it. Questions cover 3 domains: Nutrition Science and Care (41%), Food Science and Food Service (21%), and Management (38%).
How do I become a dietetic technician registered?
Meet one of CDR's two current eligibility options: an associate degree plus an ACEND-accredited Dietetic Technician Program with at least 450 supervised-practice hours, or a bachelor's degree plus an ACEND-accredited Didactic Program in Dietetics. Then pass the DTR exam and maintain the credential through annual fees and the five-year professional-development cycle.
What is the difference between DTR and NDTR?
DTR (Dietetic Technician Registered) is the credential. Some DTRs use NDTR (Nutrition and Dietetics Technician Registered) to emphasize their nutrition expertise. Both represent the same credential from CDR.
