What is a Nutrition and Dietetics Technician Registered

Nutrition and dietetics technicians, registered (NDTRs) are educated and trained at the technical level of nutrition and dietetics practice for the delivery of safe, culturally competent, quality food and nutrition services. NDTRs are an integral part of healthcare and food service management teams.

NDTRs work under the supervision of a registered dietitian nutritionists (RDNs) when in direct patient/client nutrition care in practice areas as:

  • Hospitals, clinics, nursing homes, retirement centers, hospices, home health-care programs and research facilities conducting patient/client screens, gathering data and performing assigned tasks to assist RDNs in providing medical nutrition therapy. 

NDTRs may work independently in providing general nutrition education to healthy populations in a variety of settings as:

  • Schools, day-care centers, correctional facilities, restaurants, health-care facilities, corporations and hospitals, managing employees, purchasing and food preparation and maintaining budgets within foodservice operations.
  • Women, Infants, Children (WIC) programs, public health agencies, Meals on Wheels and community health programs, assisting registered dietitians with the implementation of programs and presentation of classes for the public.
  • Health clubs, weight management clinics and community wellness centers, helping to educate clients about the connection between food, fitness and health.
  • Food companies, contract food management companies or food vending and distributing operations developing menus, conducting nutrient analysis and data collection, and overseeing foodservice sanitation and food safety.

NDTRs are nationally credentialed food and nutrition technical practitioners who have met the following criteria to earn and maintain the NDTR credential. 


Each of the following education routes leads to eligibility for application to the Registration Examination for NDTRs.

Successful completion of a Dietetic Technician Program accredited by the Accreditation Council for Education in Nutrition and Dietetics (ACEND) of the Academy, that includes 450 hours of supervised practice experience in various community-based programs, health care and foodservice facilities and has completed at least a two year associate's degree at a U.S. regionally accredited college or university. Coursework typically includes fundamentals of nutrition and nutrition across the lifespan, applied food science and techniques of food preparation, foodservice systems management, chemistry, and physiology, microbiology applied to food safety, human resource management, communications, and business. ACEND is the accrediting agency for dietetics education programs and is recognized by the United States Department of Education as the accrediting agency for education programs that prepare dietetics practitioners.
