What’s on the Exam?

Questions: 125-145
Time limit: 3 hours

 
First, let’s talk about the questions on the exam. The number of questions you get depends on how well you’re doing as you take the test. You’ll get a minimum of 125 multiple-choice questions total, and you’ll have 3 hours to answer them all.

If you answer all 125 questions before the time runs out, you’ll get up to 20 more questions to answer until the time is up.

If you don’t answer the minimum 125 questions within the time limit, you will automatically fail the exam.

 
Regardless of how many questions you answer, 25 of the questions will not count toward your score. Why is that?

Unscored Questions
The 25 unscored questions on the exam are called “pretest” questions. These are added to the exam to determine if they’re good enough questions to add to future versions of the test.

The trick is that you won’t have any way of knowing which questions are scored and which ones are pretest. They will appear just like the scored questions throughout the test.

Computer-Adaptive Testing (CAT)

The Registered Dietitian exam is a computer-adaptive test. Basically, this means that the questions will become harder or easier as you go through the exam, based on how well you’re answering the questions.

For example, say you answered the first question correctly. The first question is of medium difficulty, so the next question will be slightly harder. Then, let’s say you answered the second question incorrectly. The next question would then be a medium question.

Exam Scores

The test is scored using a scaled scoring method. Here’s how it works:

For every question you answer correctly, you get one point added to your raw score. At the end of the test, your final raw score will be converted to a scaled score. This scaled score will range somewhere between 1 and 50.

You’ll need to get a final score of at least 25 on each subtest to pass the exam.

 
The reason your raw score is converted to a scaled score is because everyone who takes the test is given a slightly different set of questions. Since everyone has a different arrangement of questions, and because some questions are harder than others, converting your raw score to a scaled score ensures a more even playing field.

Retaking the Exam

If you didn’t get a passing score on your first try, that’s okay! You can retake the test after a 45-day waiting period.
