How To Pass the RD Exam On Your First Try

Today, I want to chat about how to pass the RD Exam, how I passed the RD exam in 1 month (largely thanks to Visual Veggies), and how I became interested in nutrition and becoming a dietitian.

Fast forward 3.5 years later, that interest turned into a Nutrition Master’s degree and becoming a Registered Dietitian! Rd prep is the best thing you can invest in for the RDN exam. 

When considering how long does it take to become a Registered dietitian, passing the RD exam is pretty much the last part!


Wondering how to become a Registered Dietitian? Well, the registered dietitian exam is almost like the “final board exam” you must take in order to become a Registered Dietitian.

You have to pass the RD exam to become a credentialed dietitian, and then you’ll want to get licensed in your respective state to practice.

Hopefully, this post will reach those who are contemplating a career change, are currently studying nutrition and are an #rd2be, or maybe you’re just interested in nutrition and health like I was.

I was a career changer and wrote about how to become a Registered Dietitian if you already have a degree to make it easier for you.

After changing careers to study nutrition, I knew I wanted to focus on preventative health, work with athletes, help improve peoples’ relationships with food.

Furthermore, I wanted to help people understand the tried-and-true amid all the false information out there.

So, I started taking my prereqs in  2012, and 3.5 years later, I became a Registered Dietitian with my Master’s in Public Health.

Tips For Getting a Dietetic Internship

If you’re looking to take the exam, likely you’ve already completed your dietetic internship.

But if not, my post on becoming a dietitian walks you through all of the prereqs. I also have a full post on tips for getting matched to a dietetic internship

If you don’t apply to or get into a coordinated program, you will have to apply for a separate didactic internship, which can be a very competitive process.

What is the RD Exam Pass Rate?

According to the Academy, as of 2022, 66-71% of takers passed it on their first try. Among those taking it on their 2nd or 3rd try, 33-40% passed. While these numbers may seem intimidating, don’t freak out.

You CAN pass the test on your first try, especially with these rd exam tips.

My favorite resource, Visual Veggies, was a game changer. I’ll discuss more about why I love this resource below. You can use the code, ‘BUCKETLISTTUMMY’ for $25 off.

Another helpful resource that’s available now (but wasn’t when I was a student) is Pass Class, from All Access Dietetics! Use code ‘BUCKETLISTTUMMY’ for $120 off!

Ultimate RD Exam Prep: Where To Start

I’m going to share my favorite RD prep resources and what I used to pass the RD exam on my first try. I think you will find many of these useful as well so you can pass the RD exam on your first try. 

For example, the Inman dietitian study guide is completely worth it.

And some of the computer study programs I used for rd exam prep I would 100% recommend, like Visual Veggies and Pass Class (use code ‘BUCKETLISTTUMMY’ for $120 off Pass Class)! 

How To Study For And Pass The RD Exam 

Here is my experience with the Registered Dietitian exam (RD exam) and my RD exam prep.

If you’re looking to pass the RD exam on your first try, hopefully, you’ll find these tips helpful.

The exam can seem overwhelming, but let’s break it down. 

Worrying about passing the RD exam? The Registered Dietitian exam is the last obstacle to becoming a Registered Dietitian. This post outlines how to study or the RD exam, as well as helpful RD exam prep materials.

The RD exam is a grueling test that really tackles your critical thinking skills. I spent about a solid month studying for it, putting in a few hours each day.

I know many people who had success studying for just 1-2 weeks, and some that needed more time. 

Everyone is different, and at this point, you know best how you study and take tests because the dietitian exam pass rate doesn’t reflect how we all take tests differently. 

I’ll be the first to admit I’m not the most organized person (if you can’t tell by these pictures) but I found what worked best for me. 

Visual Veggies was SUPER helpful for me, here’s a photo of how it works below.

What Resources Do You Need for RD Prep?

  • RD Exam Study Guide – I mainly used the Jean Inman study guide and RD Exam Study Suite, and I found both to be sufficient. The Jean Inman RD Exam Study Guide, specifically, walks you through each domain. I downloaded it and would actually listen to it in my car.
    • While it’s pricey, it really focuses in on the four domains and key points of the exam – nutrition care, the science of nutrition, food service, and management of food programs and services.
  • Visual Platform Visual Veggies is a great platform for visual learners with included flashcards for prep! In my opinion, it’s the best rd exam study material. 
  • Pass Class – Unfortunately, Pass Class wasn’t available when I was in school but it has RAVING REVIEWS. You can get $120 OFF with my code, “BUCKETLISTTUMMY”
  • I also used the Krause textbook as a supplemental and a great way to refresh MNT (new 14th edition here). Please do NOT sell this book if you used it in school. It’s one you always want to keep and have in your toolbox.

RD Exam Practice Questions

I also found this software and these practice tests to be helpful.

The Visual Veggies RD Exam Study Suite has over 1,000 questions, whiteboard tutorials (believe me, these are SO helpful!), a timer like in the real RD exam setting, repeating incorrect questions and more.

It’s really worth the investment so you don’t have to retake the RD exam, with sample rd exam questions.

Plus, doing a variety of practice questions is the best way to learn!  You can find several free rd exam practice questions available on the internet. 

And if you’re a flashcards person, these already made for you flashcards are a game changer. 

I used all of these resources to make my own little RD exam study guide, and I really think they helped.

RD Exam Study Tips

These tips were super helpful as I reviewed all my rd prep and everything for the dietitian exam. 

  • I spent between 3-5 days reviewing each domain (some were shorter than others), listening to the lectures as I followed along in the study guide. Then, I rewrote things and would later rewrite them AGAIN to make flashcards (this is the best way I learn, though it is time-consuming).
  • The practice tests were so essential. I went through the practice test for each domain and really tried to understand the questions I got wrong – mostly, WHY they were wrong.
  • It is SO essential to understand the “why” to better understand the wording and writing of the test.

You have to be able to think critically like they want you to think. Visual Veggies really helped me see where my strengths and weaknesses were. 

Similarly, Pass Class also offers 1-1 tutoring options, so you can ask questions to your virtual tutor! It’s a great all inclusive resource.

  • By the last week, I was reviewing all of the domains again and basically just quizzing myself with the flashcards. And, going through the practice tests again. At this point, I was just feeling anxious about the upcoming RD exam and was ready to have it over and done with (AKA Watching Giada and The Food Network).
  • I also downloaded this app and used it for when I was sitting on the couch watching tv or reading in bed. It was a good way to spit out information for questions that were a little different from the Inman guide.

The questions were somewhat basic, but helpful for some concepts and a mindless way to review things and reminded me of my own rd exam tutoring.

Visual Veggies

Visual Veggies is also a very popular option that has a great success rate!

I love how the software visually displays your results and the percentage of questions from each domain so you can easily see your strengths and weaknesses.

They also have tons of different study tools, like flashcards and an app too. Best of all, they have reduced pricing for students too, PLUS $25 off with my code, BUCKETLISTTUMMY.

Here’s an example of all of what you have access to with the Study Suite! You can focus in on one domain, have study sessions, study with a guided plan and more.

I also found that Visual Veggies offered great practice for learning to take the actual RD test on the computer.

Pass Class

As I mentioned, Pass Class came out AFTER I became an RD, but it’s a resource I totally would have used!

It’s an all inclusive resource with videos, an interactive study guide, and you have access to tutors! Over 2,500 rd’s to be have used the software.

Other Tools

I know people have loved and used  Hess and Hunt, RD Flashcards and other study resources.

I can’t speak to them since I didn’t use them but I know registered dietitian study flashcards worked for others!

In my opinion, picking a few will be the least overwhelming option and help you study efficiently for the RD exam.

Final Advice for Taking the Registered Dietitian Exam:

  1. Allow ample time to prepare yourself.
  2. Schedule the exam as soon as you are eligible. If you don’t use it, you lose it. Knowledge fades fast.
  3. Do all of the practice questions and then some. Use them to focus on your weak points.
  4. Make studying fun. Use the resources that work best for you! I outlined many above, but some may work BEST for you.
  5. Eat a filling breakfast the day of. The last thing you need when you want to pass the RD exam is feeling hungry, sluggish or tired. As RD’s, we know this already, but reminders always help. Some easy breakfast favorites include high protein overnight oats, skillet breakfast scramble, and apple pumpkin pie oatmeal.
  6. The exam is hard. Not everything you studied will be on it, and vice versa. You’ll doubt yourself during it but be assured that you know this.
  7. You’ve taken harder tests throughout school, memorized all of the biochem pathways, worked with carbohydrate counting, and likely treated someone with chronic disease. You got this!
  8. Celebrate! Becoming an RD is SUCH a proud moment and accomplishment. So much work goes into it. You deserve to celebrate!

    Hence, my question to you is,
    After my msc in clinical nutrition, can i pursue pg diploma in dietetics? Will i be eligible to give the RD exam?
    Eager to hear from you.
    Thank you.

  3. This article shade a ton of light. Bumped into it just at the right time while feeling overwhelmed with all preparations. I’m preparing for KCAT which is the very first step of CDRE/ RD exam process.
    I’m reaching out to see if you could help me with any tips and resources or practice test links/ sites I could find to prepare for KCAT.

  4. I graduated from the coordinated program at Ohio State in 1981. I practiced as an RD for 6 years, then went into hospital administration field for over 2 decades. After 28 years of not practicing dietetics, I decided to study for the exam. I studied for 9 months and passed with a 33. That was 3 years ago. I still have not practiced since then in my retirement. I wanted to do it for the challenge and relearning everything. I studied Inman, and took practice tests.

    1. HI Larry. I graduated MS of Nutrition and dietetic internship program on 2010. I did not pass the RD exam and work as a diet tech for 5 years. I stayed away from hospital job and “nutrition world” for 8 years.. After I read your experience, I decided to start to take a RD exam one more time. I am scared the materials might be changed and I need to be updated. I want to make sure you studied Inman alone?

  5. I graduated in Dietetics and changed my career to a Pharmacicst. After 16 years, I am studying for the RD Exam. I would love to form a groupme for people who has been out of the career for an extended period of time.

  6. I have taken the test 4 times and failed! I just turned 50. I have been a DTR for over 25 years. I work as a Dietitian, been here for 18 years. I know this stuff! Just can’t pass! Any recommendations?

    I have used Inman, Visual Veggies, Flash Cards etc…..

  7. I was a dietitian for 6 years and then went into hospital admin. I kind of retired and then decided to get back my RD. I studied for months and just recently passed the test with 33 after 28 years. Congratulations to you!

    1. I am studying after two years of finishing my degree…I have not taken the exam D/t personal circumstances.. How did you study and pass after long period of time? Any advice? Resources?

    2. Hello, I also was an RD for many years – dropped the credential. Now interested in getting it back after 22 years
      I became a professional coder – hardest test I ever took, so I’m thinking the RD exam again may be doable.
      Any insights?

    3. Help! I am considering the exam again after 32 years!! If you have any suggestion Lallong I would certainly welcome it!

      1. Hi Julie, I am retaking the exam after 22 years. I am just starting to gather study materials now. I am wondering if you ended up taking it and if you have any advice?

  8. Thank you so much for sharing! If all goes well, I’m planning on starting next fall to get my RD! I love hearing how other people got into nutrition and went through schooling! Such helpful info!

  9. I don’t know why it’s taken me so long to discover your blog, but HI! 🙂 Yay BGB member love! I’m a dancer and I’m also very interested in nutrition and health coaching. This post is really inspiring me right now because I feel like nutrition is really the path for me, and maybe not dance. Subscribing to your blog right now! <3

    1. HI! I’m so grateful for BGB. That’s so exciting that you’re thinking about going into nutrition – let me know if you have absolutely any questions! 🙂

  10. Great post. I think you covered the important tips for passing the exam. I used the same study guide and basically just studied stuff over and over again. I personally found that writing down info helps me so I filled up a whole notebook jotting down important things I wanted to remember.

    Also – I didn’t know you went to UMass – I did my masters there! 🙂

  11. Loved this post! It is funny because I went into dietetics because I had no idea what to do with myself, I had no previous nutrition knowledge, like whatsoever. It was only once I was in the program that I fell in love with nutrition! I hope when I graduate someone makes me a cake at least half that nice !! 🙂

  12. It’s so awesome that you went back to school to get your RD credentials. It seems like a lot of work, but if it’s what you want to do, then it’s totally worth it.

  13. I actually changed my major in college to public health because I was unhappy in the current major. I was asking myself, would I be happy for the rest of my life doing that? The answer was no and it was scary but I’m so glad I switched. I don’t regret it at all.

    1. That’s great. I agree it can be scary and unknown but if you’re passionate and know what will make you happy, it only seems sensible to go for it. Kudos to you for making the switch as well.

  14. This is so exciting! I’m so glad you did this. I have met so many virtual RD’s online, and they have been SUCH a blessing to me with their nutritional advice on their blogs.

  15. Mad props for making the switch and pursuing something you were passionate about! And I think it’s so awesome that you included study tips for the RD exam since I’ve heard it can be a bit of a doozy.

  16. LOVE THIS. You have to follow what drives you. That is not only how you get the most out of life but also how you do the best serving others. AKA how you reach rockstar status. Congrats!

  17. I think it is so awesome that you made the switch! I think a lot of people stay in jobs that don’t make them happy because the feel it is too late to go back.
    I’m really concerned about the RD exam at the moment… but I foresee different feeling over the next couple of months!
