2027–2031 specifications published — the blueprint changes on 1 January 2027

CDR approved new Registered Dietitian Examination test specifications on 25 June 2025, effective for exams taken from 1 January 2027. The four domains are restructured: Fundamentals of Dietetics Practice 23%, Community and Public Health Nutrition 22%, Human Nutrition and Medical Nutrition Therapy 40%, Food Science and Food Systems 15%. Community and Public Health Nutrition is new as a standalone domain, and the single 45% nutrition-care domain becomes a 40% clinical domain. Use the exam-specification tool to see which set applies to your date.
