The Commission on Dietetic Registration has an RD exam that is used by states for licensing purposes. CDR has a number of tips for preparing for this licensing test for registered dietitians. Study guides and references are available to all students.
As part of the process of getting registered as a dietitian, most applicants will have had a formal education, as that is a common requirement for education. Those who have not completed their education should be aware that there are specific references recommended by the Commission on Dietetic Registration to get ready for the RD exam.
The Commission has an RD “Handbook for Candidates.” All aspiring registered dietitians should download this handbook.
First, look at the handbook and find the section with the RD exam references. There are two sets of books: one for Food and Nutrition Services and one for Foodservice Systems/Management. Both sets of dietitian reference textbooks are necessary, as you must take a pass both of these to get past the RD exam and become a registered dietitian.
Ideally, study these books from cover to cover and memorize the contents. This will naturally give you the best shot at passing the RD test. If you do not have the time or money for that, at least find some way to review all the major topics on the test. Of course, this can be a very expensive process. Keep your textbooks if you are still getting your registered-dietitian education to avoid additional expense in the future.
The handbook also has the RD exam content outline. These are all of the topics on the exam and the approximate percentage of questions by category. Use your reference materials to make sure you thoroughly cover each testable topic.
Finally, the handbook also has some RD practice questions. Use those to assess whether you are ready for the exam well before the scheduled test day. That way, you will have time to go back and sharpen your weak areas before you take this registered-dietitian test.
Note: There is a separate application and registration process for dietetic technicians. These applicants should download the “Registration Information for Dietetic Technicians Handbook for Candidates” to get all the information about how to become a registered dietetic technician and how to take that separate DTR exam.
