Dietetic Technician, Registered (CDR) Certification Exam

Dietetic Technician, Registered (CDR) Food service operations, medical nutrition therapy calculations, and patient counseling scenarios dominate the DTR exam. You’ll navigate real-world situations like adjusting therapeutic diets for renal disease, managing inventory in high-volume kitchens, and documenting nutrition interventions. The CDR assessment pulls from everyday dietetic technician work—the hands-on tasks that define the role in hospitals, clinics, and community settings.
