To become a Registered Dietitian, you need a graduate degree that includes ACEND-accredited dietetics coursework, at least 1,000 hours of supervised practice, a passing score on the Commission on Dietetic Registration (CDR) national exam, and payment of the initial registration fee. Most people reach the credential in six to eight years from the start of an undergraduate program.1Commission on Dietetic Registration. RDN Credential – Frequently Asked Questions The title Registered Dietitian (RD) and Registered Dietitian Nutritionist (RDN) are legally identical; you choose which one to use after you pass.
Step One: Earn the Required Degree and Coursework
Since January 1, 2024, every first-time candidate must hold a graduate degree from a regionally accredited institution. A bachelor’s degree alone no longer qualifies.2Commission on Dietetic Registration. 2024 Graduate Degree Requirement – Registration Eligibility
The dietetics coursework itself has to come from a program accredited by the Accreditation Council for Education in Nutrition and Dietetics (ACEND).3EatRightPRO. Accreditation Council for Education in Nutrition and Dietetics (ACEND) Most candidates satisfy this through a Didactic Program in Dietetics (DPD), which covers biochemistry, physiology, medical nutrition therapy, food science, and community nutrition. When you finish, the program director issues a verification statement. You will need that document to enter supervised practice and later to sit for the exam.
You have some flexibility in how you combine the pieces. Some students take a master’s degree that bakes in the DPD curriculum. Others complete a DPD separately and then earn a graduate degree in a related field like public health or food science.
Step Two: Complete 1,000 Hours of Supervised Practice
Classroom work is only half the preparation. Every candidate also has to log at least 1,000 hours of hands-on training through an ACEND-accredited supervised practice program.4Academy of Nutrition and Dietetics. About Accredited Programs There are three ways to do this:
- A Dietetic Internship (DI), the traditional standalone route taken after finishing a DPD and at least a bachelor’s degree. Some internships pair with a graduate degree.
- A Coordinated Program (CP), a graduate-level program that weaves coursework and supervised practice together in one curriculum.
- A Graduate Program in Nutrition and Dietetics (GP), formerly called the Future Education Model, which combines didactic learning and the 1,000 supervised hours into a single competency-based graduate program. Some GPs include DPD content; others require a DPD verification statement up front.4Academy of Nutrition and Dietetics. About Accredited Programs
Whichever pathway you choose, your rotations will cover three core areas: clinical nutrition (usually hospital-based work with medically complex patients), community nutrition (public health programs and outpatient counseling), and food service management (large-scale production, safety protocols, and budget oversight). All three have to be completed before you can apply for the exam.
Step Three: Apply Through the Match
Supervised practice slots are competitive and are filled through a centralized matching system. You submit your application through the Dietetic Internship Centralized Application Services (DICAS) portal, which works like a common application: educational history, transcripts, a personal statement, and your list of chosen programs. The first program designation costs about $50, and each additional designation runs roughly $25.
Programs review and interview, then both sides submit ranked preference lists to D&D Digital, which runs the matching algorithm. The spring cycle has a February deadline with April results; the fall cycle runs on a September deadline with November results. If you don’t match in the primary round, a second phase opens where unmatched applicants can apply directly to programs with open spots.
D&D Digital charges a separate match registration fee. Between the DICAS designations and the match registration, plan on roughly $100 to $200 depending on how many programs you apply to. Match rates swing from year to year, so applying broadly helps.
Step Four: Pass the Registration Exam
Once you finish supervised practice, your program director handles the eligibility paperwork, submitting your information to CDR through the Registration Eligibility Processing System (REPS).5Commission on Dietetic Registration. Program Director Instructions You don’t file your own eligibility application. Give the director your completed forms and documentation, and they enter it on your behalf.
After CDR confirms you meet all requirements, your name goes to Pearson VUE, the testing vendor, and you get an Authorization to Test email in about 48 hours. The authorization is valid for one year; if you miss that window, you have to reauthorize with CDR.6Commission on Dietetic Registration. RD Handbook for Candidates
The exam fee is $225, paid by credit card when you schedule your appointment on Pearson VUE’s site. Appointments have to be booked at least 48 hours ahead. On test day, bring one valid, unexpired government-issued ID with your name, photo, and signature; the name must match your Pearson VUE profile exactly. Workplace and university IDs are not accepted.7Commission on Dietetic Registration. RD Handbook for Candidates Centers use palm-vein biometric scanning, and personal belongings go into secure storage before you enter.
The exam is computer-adaptive. Question difficulty shifts based on how you answer, and the test can end anywhere between 125 and 145 questions once the system has enough information to make a pass or fail determination.8Commission on Dietetic Registration. Commission on Dietetic Registration Frequently Asked Questions You get your score immediately. Clinical nutrition content is the largest portion, so expect heavy emphasis on patient assessment and medical nutrition therapy.
The first-time pass rate for the second half of 2024 was 63.1 percent.9Commission on Dietetic Registration. First Time Pass Rate July-Dec 2024 If you don’t pass, you have to wait 45 calendar days to retest and pay the full $225 again.7Commission on Dietetic Registration. RD Handbook for Candidates
Step Five: Pay the Initial Registration Fee
About 72 hours after you pass, CDR emails a fee notice. Pay the $80 initial registration maintenance fee through the MyCDR portal. CDR will not verify your credential to employers or release your digital credential until payment clears.10Commission on Dietetic Registration. Registration Maintenance Once it does, you’re officially an RD or RDN and can start practicing.
Step Six: Get Licensed in Your State
The RD credential is a national certification, not a license to practice. Most states have their own licensure, certification, or title protection laws that control who can provide nutrition services.11Commission on Dietetic Registration. CDR Certification vs. State Licensure – What is the Difference? The level of regulation varies:
- Licensure is the strictest. Only licensed practitioners can use protected titles or deliver services within a defined scope of practice such as medical nutrition therapy.
- State certification confirms you meet qualifications and protects the title, but uncertified people are not shut out of all nutrition work.
- Title protection only means that just qualified individuals can call themselves dietitian or nutritionist, with no regulation of the practice itself.
If you work across state lines, especially through telehealth, the legal requirement follows the client’s location, not yours. CDR recommends holding licensure in every state where your clients live.11Commission on Dietetic Registration. CDR Certification vs. State Licensure – What is the Difference? State fees and renewal requirements are separate from the CDR fee, so budget for both.
Keeping the Credential
The RD runs on a five-year recertification cycle. In each cycle you complete 75 continuing professional education units (CPEUs), including at least one in ethics or health equity, tracked through CDR’s Professional Development Portfolio.12Commission on Dietetic Registration. Recertification Information
You also owe an $80 annual registration maintenance fee, due August 31 each year. The fee is scheduled to rise to $90 on June 1, 2027. If you miss the fee past March 31 of the following year, CDR terminates your credential.10Commission on Dietetic Registration. Registration Maintenance If your Activity Log isn’t submitted by the June 30 deadline in your final cycle year, your credential lapses effective September 1, and reinstatement requires retaking and passing the registration exam.13Commission on Dietetic Registration. CDR Professional Development Portfolio Guide
Optional: Board Specialization Later On
After you have practice experience as a credentialed RD, you can pursue a board-certified specialist credential through CDR in one of eight areas: Digestive Health, Gerontological Nutrition, Obesity and Weight Management, Oncology Nutrition, Pediatric Nutrition, Pediatric Critical Care Nutrition, Renal Nutrition, or Sports Dietetics.14Commission on Dietetic Registration. Board Certified Specialist Each specialty requires documented practice hours and a specialty exam. Sports Dietetics, for instance, requires 2,000 hours of sports dietetics practice in the preceding five years for initial certification.15Commission on Dietetic Registration. CSSD Eligibility Requirements Specialization is not required to practice, but it can open roles in hospital systems, sports organizations, and specialty clinics where generalist RDs may not be considered.
