Passed the RD Exam? Next Steps for Your Fee, Credential, State License and First PDP Cycle

After you pass the RD exam: the order of steps

CDR's Newly Credentialed graphic, its registration maintenance page and the 2026 handbook set out the sequence, checked on October 27, 2026:

One inconsistency to know about: CDR's graphic says practitioners have 60 days from billing to pay, while the registration maintenance page puts the late fee at 90 days and termination at 120. Paying in the first days makes the difference irrelevant.

The fee matters for more than the late charge. CDR's own definition of a registered dietitian, in its credentialing tip on non-registered status, includes having passed the registration exam and paid the annual registration fee.

When you can start using RD or RDN

CDR's credential use policy says the marks are for people who have completed the credential requirements and have been notified by CDR in writing that they've achieved the certification. Before that, these aren't allowed:

• Pre-validation use. CDR says eligibility to sit for the exam isn't an indication that someone will schedule, sit for or pass it.
• "Eligible" titles. "RDE," "RDNE," "RD eligible" and "RDN eligible" aren't credentials.

RD or RDN: your choice. CDR's RDN FAQ says the two have identical meanings and legal trademark definitions, there's no extra cost for using RDN, the same recertification rules apply, and the registration ID card shows both. Pick one and use it consistently.

What the policy allows and forbids. You may use your credential on business cards, letterhead, websites and in names such as an email address or a business name built from your own name. You may not put it on a product or offering, such as a supplement name or "approved by" wording, and you must stop using it if you don't maintain the credential.

State licensure is a separate step

CDR's certification vs licensure tip sheet says most states require dietetics practitioners to hold a state license or certification to practice or to use a protected title, and that requirements vary by state. For a newly credentialed RD, the main points are:

• Endorsement of the RD credential. Where a state allows it, using your RD credential to reduce the paperwork for a state license is usually the easiest route, CDR says.
• Where your patients are. For in-person or telehealth care across state lines, CDR says practitioners must comply with the licensure and telehealth laws of the state where the patient is physically located at the time of service, unless an exemption applies or the state doesn't regulate dietetics.
• Scope can differ by state. Some states reserve medical nutrition therapy for licensed practitioners while allowing general nutrition education by others, and some regulate all nutrition and dietetics services.
• Ethics ties in. The Code of Ethics asks practitioners to comply with applicable laws, including obtaining and maintaining a state license where nutrition and dietetics statutes require one.

The same tip sheet notes that some states offer a temporary or provisional license to people who are exam-eligible, usually under supervision, so they can practice while they prepare. If that's your situation and you haven't tested yet, you can see what planned full prep covers across the four 2027 domains while you build your schedule.

The Dietitian Licensure Compact in 2027

CDR's compact page describes an agreement among participating states that lets an RD practice in other member states through a "compact privilege," using one home-state license. To use it, you need to be an RD with an active, unencumbered license in a home state that belongs to the compact. CDR says that if you live in a state without licensure (it gives California and Arizona as examples) or a state outside the compact, you can't use it. The first compact privileges are expected to be issued sometime in 2027, and you'd need to meet continuing education requirements only in your home state.

Your first Professional Development Portfolio cycle

CDR's Universal PDP Guide sets the recertification rules:

The Learning Plan comes first: CDR says it must be completed before you can access the Activity Log, and activities can be entered any time during the cycle after that. Creating it early lets you log each activity as you finish it.

Registration fees from 2027

Every year after the first, CDR emails a fee payment link in early June, and the RD fee of $80 is due by August 31. A $50 late fee applies from September 1 to September 30, and if payment isn't received by September 30, registered status is terminated. CDR has scheduled an increase in the RD fee to $90 on June 1, 2027. The RD exam cost guide puts the exam and registration costs together.

If you're reading this before your exam

Knowing the steps ahead can make the date feel more concrete, but the order still starts with test day. The RD exam test day guide covers the ID rule and check-in, and close to the date, the full prep planned for launch adds Test Day reminders and a Cram plan for the final days.

CDR's own study tips also recommend a study group, in person or virtual, for support and accountability, and suggest explaining a topic to someone else as a way to understand it better. If classmates from your program are testing around the same time, that group is easy to form.
