I used Examsdr's practice tests to prep for my Registered Dietitian exam and honestly, they were a lifesaver. The questions on medical nutrition therapy and nutrition assessment really mirrored what I saw on the actual test. The explanations helped me nail down the trickier stuff like enteral nutrition calculations and food service management. Passed on my first try and couldn't be happier.

Frequently Asked Questions
What is the Registered Dietitian exam?
The Registered Dietitian exam (officially called the Registration Examination for Dietitians) is administered by the Commission on Dietetic Registration (CDR). It's the final step to becoming a Registered Dietitian (RD) or Registered Dietitian Nutritionist (RDN), which qualifies you to practice in most states.
What subjects does the exam cover?
The exam covers four main areas:
- Nutrition Care for Individuals and Groups (40%)
- Principles of Dietetics (25%)
- Management of Food and Nutrition Programs and Services (21%)
- Foodservice Systems (14%)
These percentages reflect how questions are weighted across different practice areas.
What format is the exam?
The exam uses Computer Adaptive Testing (CAT). This means the difficulty of questions adjusts based on your answers. You can't skip questions or return to previous ones. Each question must be answered before moving forward.
How long should I study for the Registered Dietitian exam?
Most dietitians study for 2 to 4 months, dedicating 8 to 12 hours per week. Your study timeline may vary based on how recently you completed your internship and how comfortable you feel with the material.
What happens after I pass the Registered Dietitian exam?
After passing, you become a Registered Dietitian (RD) or Registered Dietitian Nutritionist (RDN). You'll need to maintain your credential by completing continuing education and submitting a Professional Development Portfolio every five years. Depending on your state, you may also need to apply for state licensure or certification to practice legally.
How do I schedule my Registered Dietitian exam?
After CDR verifies your eligibility, you'll receive an email with instructions to schedule through Pearson VUE. Log into your Pearson VUE account, select an available date and location, and pay the exam fee. You can schedule your exam as soon as you receive authorization or wait until you feel fully prepared (within your one-year eligibility window).
What study materials should I use?
The CDR Study Guide is the official study resource available from the Commission on Dietetic Registration website. Many dietitians also use practice test from Examsdr to prepare for the exam format and identify weak areas. Most successful candidates focus on one or two comprehensive resources rather than spreading themselves too thin. Choose materials that match your learning style and stick with them throughout your preparation.
