Registered Dietitian Practice Test

Dietitians are an important part of the medical field. These are the professionals who help you make good choices about the foods you eat in order to maintain a healthy lifestyle. It’s a satisfying profession because you help people in so many ways, including nutrition care and food management, and teaching people ways healthy food can prevent disease. The Commission of Dietetic Registration plays a big part in the accreditation process to become a registered CDR dietitian because it has created the test — the Registered Dietitian — you have to pass to get this coveted designation. It’s also a good time to consider this career, as the Bureau of Labor Statistics estimates job growth in this field at 15 percent through 2026, a pace that’s far more robust than many other professions. If you’re interested in becoming accredited in this field, there are several things you should know.

The maximum number of questions total 145 — 120 scored, 25 not scored. If a student fails to complete at least 125 questions, the student will fail the test.

How long does the test take?

The total examination time is 3 hours — 2.5 hours to take the test, 20 minutes to complete a tutorial and 10 minutes to finish the post-examination survey.

Is there a fee to take the exam?

Yes. The fee is $200.

How long does it take to get authorization to take the Registered Dietitian?

It takes between two and three weeks from the time the Commission of Dietetic Registration reviews candidate qualifications, and the candidate receives the examination application.

Once I receive the authorization to take the exam, how long do I have to take it?

The authorization is good for one year.

What else will happen at check-in?

Eyeglasses will be examined before entering the testing room, and candidates will have their palms scanned to confirm identity.

Can I bring personal items into the room when I’m taking the Registered Dietitian?

No. The basic rule of thumb is no electronic devices of any kind are allowed, including cell phones, hand-held computers/personal digital assistants (PDAs) or other electronic devices. These must be turned off and placed in a secure area before entering the testing room.

You can’t bring those in either. Watches, purses, coats, bags, and hats are among the items not allowed.

It contains a ton of great information and it’s making me start to feel more comfortable about being ready for the RD exam.

That really helps with keeping the information planted neatly into my brain and is helpful when studying.

I think that the organization of the material is great and I also really appreciate that there were free study tools offered on the website as well (overcoming test anxiety, study secrets, vocab list, etc.). I also like that the section in the study guide about types of learning and what can be most effective because I often learn that through trial and error, which can be a huge waste of time!
