What your students practice
The Registration Examination for Dietitians (the RD exam) is the Commission on Dietetic Registration's credentialing exam for the Registered Dietitian (RD) or Registered Dietitian Nutritionist (RDN) credential. It is computer adaptive and taken year-round at Pearson VUE test centers: each candidate answers between 125 and 145 four-option questions (100 to 120 scored plus 25 unscored pretest) in 3 hours, with no going back to earlier questions. Scores are scaled from 1 to 50, and 25 is the minimum passing score. Under the test specifications in force from January 1, 2027 the domains are Fundamentals of Dietetics Practice 23%, Community and Public Health Nutrition 22%, Human Nutrition and Medical Nutrition Therapy 40% and Food Science and Food Systems 15%; exams through December 31, 2026 follow the 2022 to 2026 outline.
Tigertest's practice follows The CDR Registered Dietitian Examination Test Specifications (2022 to 2026 and 2027 to 2031) and the CDR RD and DTR Exam FAQ (2025), checked November 2026. Students train in short sets where missed questions come back until they are mastered, then take full practice tests.

Questions teachers ask
Is the RD Exam class free?
Yes. Classes are free for teachers. A student in your class also gets that test's full stats and every step of it at no charge.
Do my students need accounts?
No. A student opens your class link, types the name you know them by and starts practicing. An account is optional and keeps their progress across devices.
What do I see as the teacher?
Who practiced and when, each student's practice test scores, the RD Exam topics the class is weakest on, and every question the class answered with how many missed it and which wrong answer they picked.
Can I use my own questions too?
Yes. Any account can turn its own material into a Tigertest quiz and limit it to one class, so only your students can play it.
