DTR: Dietetic Technician Registered Examination Practice Test

To be eligible, you must have completed at least an associate's degree from a dietetic technician program accredited by the Accreditation Council for Education in Nutrition and Dietetics (ACEND). This includes the completion of a supervised practice component. Alternatively, individuals who have completed a bachelor's degree in nutrition/dietetics from an ACEND-accredited program (without the supervised practice for the RDN) or those who are already Registered Dietitian Nutritionists (RDNs) are also eligible. Official verification of completion from your program director is required.

The DTR exam is a computer-based test consisting of 125 scored multiple-choice questions, plus an additional 25 pretest questions that are not scored. Candidates have 3 hours to complete the examination. The questions are designed to assess application and analysis of knowledge across four primary domains outlined in the test blueprint: Food, Nutrition, and Dietetics; Nutrition Care; Foodservice Systems; and Management.

The DTR credential is maintained through the Commission on Dietetic Registration's (CDR) Professional Development Portfolio (PDP) process. DTRs must earn 50 hours of continuing professional education (CPE) every 5-year cycle. These CPE activities must be relevant to the practice of dietetics and nutrition and are logged in CDR's online system. This requirement ensures certified professionals stay current with evolving science, technology, and practice guidelines.

DTRs work under the supervision of RDNs in settings such as hospitals, long-term care facilities, community/public health programs, school foodservice, and wellness centers. Common job titles include Clinical Dietetic Technician, Nutrition Assistant, WIC Nutritionist, and Foodservice Manager. According to industry salary surveys, compensation varies by location, setting, and experience, but typically ranges from $35,000 to $55,000 annually. The credential provides a stable foundation for career advancement and is a recognized step for those pursuing further education to become an RDN.

As of 2022, the CDR updated the credential title from Dietetic Technician, Registered (DTR) to Nutrition and Dietetics Technician, Registered (NDTR) for new certificants. The change reflects the evolving scope and broader focus of the profession. The credentialing requirements, exam content, and scope of practice remain identical. Individuals who certified prior to 2022 retain the DTR title but are considered equivalent to NDTRs in practice and credentialing standards. Both titles represent the same certification and level of competency.
