Dietetic Technician, Registered (DTR) Examination

Students who meet the criteria to receive a verification statement from the Penn State DPD program are eligible to take the DTR examination. Students who take the DTR exam typically choose not to apply to a DI program or are not matched to a DI program.

What does a dietetic technician do?

Dietetic technicians work as dietary aides in clinical settings, such as hospitals and long-term care settings; they work in school food service; and they work as research lab assistants, etc. The Academy of Nutrition and Dietetics provides additional information on employment opportunities, job outlook, and salary information.

What are the advantages of taking the DTR exam?

Students should take the DTR exam if the job for which they are applying requires the DTR certification. While the certification will not hurt the student’s chances of getting employment, there are some states that do not require the DTR certification. It is possible for an individual to get a nutrition-related job without it. This will vary by state and by employer.

Students who are planning to apply to a DI program or an Individualized Supervised Practice Pathway (ISPP) are encouraged to take the DTR exam. Directors of these programs look favorably on applicants who have earned their DTR certification.

National board examination for Registered Dietitian Nutritionists (RDN)

Similar to other health care professions, RDNs must take and pass a national board registration examination to earn the RDN certification. The RDN exam is a computer-based exam that covers the content in the three major areas of dietetics: clinical, community, and food service.

The registration examination is updated every five years to reflect the information that entry-level dietitians should master after completing a Didactic Program in Dietetics (DPD) and Dietetic Internship (DI) program. The exam was updated in January 2012.
