RD Exam Test Day at Pearson VUE: ID, Check-In, What You Can Bring and How the Session Runs
What happens on RD exam day, from the ID check to the printed score report: the one ID CDR accepts, why arriving late costs the fee, what goes in the locker, which comfort aids need no approval, how breaks and the clock work, and what to do if something goes wrong.
Short answer
For the RD exam at a Pearson VUE test center, bring one original, unexpired government-issued ID with your name, photo and signature, matching the name in your Pearson profile. CDR's study tips suggest arriving at least half an hour early, and a late arrival isn't seated and loses the fee. Phones, watches, bags, notes and other personal items go into storage. Expect an eyeglasses inspection, a security wand and possibly a palm-vein scan. The 3.5-hour appointment covers a 20-minute tutorial, 3 hours of testing and a 10-minute survey, and you leave with a printed score report.
RD exam day at a glance
These steps come from CDR's 2026 RD Exam Handbook for Candidates and its study and rescheduling sheets, checked on October 27, 2026:
| Stage | What happens |
|---|---|
| Before you leave | Have your one qualifying ID. CDR's tips: eat a small meal that won't upset your stomach, and allow time for travel |
| Arrival | CDR suggests arriving at least half an hour early. A late candidate isn't seated and forfeits the exam fee |
| Check-in | ID check, eyeglasses inspection, security wand, and possibly a palm-vein scan. Electronic devices are powered off and stored before you reach the proctor station |
| Tutorial | About 20 minutes, with instructions and practice questions, before the exam timer starts |
| Exam | 3 hours from question one, 125 to 145 questions, no going back |
| Finish | Your score appears on screen. A 10-minute survey is part of the appointment, and you get a printed score report after you return the note board |
The whole appointment is 3.5 hours. How to pace the questions is covered in the RD exam format guide. In the last few days, you'll be able to see the planned Test Day checklist of format reminders once full prep launches.
The ID rule for the RD exam
The handbook accepts one form of ID only: an original, valid (unexpired) government-issued ID that shows your name, photograph and signature.
- The name must match. Your current legal name on the ID must match your Pearson profile. Your address doesn't have to match.
- Testing outside your country of citizenship? If you don't have a qualifying ID issued by the country you're testing in, the handbook requires a passport from your country of citizenship.
- Not accepted: workplace or university ID.
- Fix name problems before test day. Profile changes go through CDR's website, and a name change needs an original legal document (marriage license, divorce decree or court order) or a notarized copy. When you submit it, check the box saying you'll be taking the exam so CDR can notify Pearson.
The proctor may dismiss a candidate whose ID name doesn't match the name in Pearson's system, and CDR's ATT sheet says authorization also ends if you fail to present a qualifying ID.
Security check-in at the test center
The handbook describes three checks:
- Eyeglasses. Every candidate removes their glasses for visual inspection. They're treated as a comfort aid and allowed in the testing room afterward.
- Security wand. Pearson enforces a zero-tolerance policy on unauthorized electronic devices. You'll be told to power off and store phones, smart watches, camera glasses and other devices before heading to the proctor station. A candidate found with a device at the proctor station isn't permitted to test and forfeits the fee.
- Palm-vein recognition. Pearson may scan your palm to confirm your identity. CDR says it doesn't collect or have access to these scans, and that questions about them should go to Pearson.
What to leave in the locker, and what you may keep
Not allowed in the testing room, under the handbook's rules: cell phones, tablets and other electronic devices, watches, wallets, purses, hats and other head coverings, bags, coats, books and notes. You store them in a secure area the administrator shows you, with devices turned off. Studying isn't allowed in the test center.
Comfort aids that don't need approval. The handbook points to Pearson's accommodations page for comfort aids, and Pearson's list allows these after visual inspection, among others:
- Eyeglasses without the case
- Medical devices attached to the body that make no sound, such as a continuous glucose monitor or insulin pump
- Unwrapped glucose tablets, cough drops and pills, not in a bottle or container
- Eye drops, nasal spray, an inhaler and an auto-injector such as an EpiPen
- Bandages, braces, casts and slings, and a pillow or cushion
- At Pearson Professional Centers, earplugs or noise-reducing headphones and tissues provided by the test center
Items outside these conditions, such as a medical device that makes noise or a phone or remote control that goes with a device, need an approved accommodation, applied for through Pearson before you schedule. Approved accommodation appointments are booked by phone, using the approval letter.
Inside the testing room
- Your workstation. You sit in an assigned seat until you're escorted out. Eating, drinking, smoking, chewing gum and disruptive noise are prohibited. Raise your hand if you need help.
- Monitoring. You're continuously monitored, and the session may be recorded.
- The note board. You may use the erasable note board only after the exam starts, it can't leave the room, and you return it as soon as you finish.
- The calculator. A simple pop-up calculator is on screen, and a simple handheld one may be provided. CDR's FAQ says you can't bring your own. The handbook says you must examine and test whichever you use before the exam begins.
- The clock. The 3-hour timer starts with question one, and you can hide it.
- Navigation. You must answer each question to move on, and you can't review or change earlier answers.
Breaks during the RD exam
The timer doesn't stop for an unscheduled break. During one, you can't use personal items, except medication you must take at a specific time, with the administrator's approval. If you have an approved accommodation for breaks, the administrator puts the workstation in break mode, you take your ID with you, and you're checked and re-scanned for devices before the exam restarts.
A practical approach is to decide in advance whether you'll take a break at all, and when. With 125 to 145 questions in 180 minutes, every minute away comes out of your testing time. Three hours of focus takes practice too, and full prep is planned for it: at launch, you'll be able to build that stamina with the planned 1,700 exam-style questions.
If something goes wrong on RD exam day
| Situation | What CDR says to do |
|---|---|
| A problem during the exam affects your ability to test | Raise your hand and notify the administrator immediately |
| You fall ill within 48 hours of the appointment | Email cdrexams@eatright.org with an explanation and documentation. CDR's rescheduling sheet says that with a physician's letter, CDR will have Pearson cancel and refund the fee |
| The test center closes for weather or an emergency | Pearson emails you about the closure and how to reschedule |
| You're running late | You won't be seated if you arrive late, and the fee is forfeited |
Report problems at the time. The handbook says appeals of a failing score, of individual test items or of content validity won't be considered, so the test center is where an issue can be dealt with. The RD exam cost guide lists every refund and forfeit rule.
When you finish the RD exam
The administrator makes sure your exam ended properly. Your score appears on the screen, and once you've returned the note board and other materials, you're given a printed score report. If you don't receive one, the handbook says you can get it through Pearson's scheduling portal or from Pearson VUE.
Under the non-disclosure agreement you accept, you can't take questions or answers out of the center or discuss them with other candidates. The passing score guide explains what the report shows, and if you passed, the after-passing guide lists what to do next.
Your RD exam week: a short checklist
- Find the confirmation email. CDR says that without it, you haven't successfully scheduled.
- Compare your ID with your Pearson profile, letter by letter.
- Try the Pearson demo test at pearsonvue.com/CDR to see the navigation and on-screen calculator, and Pearson's CDR page also links an online tour of a Pearson Professional Center.
- Plan the route and timing. CDR's tips suggest checking directions and travel time, choosing comfortable clothing, and an early test time if you can get one.
- Rest the day before. CDR's infographic suggests exercise, fluids and rest, and not studying the day before.
- Do one last mixed set earlier in the week, not the night before. The 20 free RD exam practice questions mix all four domains. Close to the date, you can use the planned Cram tool to focus the final days on traps once full prep launches.
