Becoming a registered dietitian (RD) requires a graduate degree, supervised practice hours, and passing a national exam. Since January 1, 2024, a master’s degree is the minimum to sit for the registration exam, up from the previous bachelor’s degree requirement. The full process typically takes six to eight years after high school, depending on the pathway you choose.
Step 1: Earn the Right Degree
You need a graduate degree from a regionally accredited institution. This has been the rule since January 2024, when the Commission on Dietetic Registration raised the bar from a bachelor’s to a master’s degree. If you’re starting from scratch, that means completing an undergraduate program first, then a master’s. If you already hold a bachelor’s degree in another field, you can pursue a master’s in nutrition or dietetics directly, though you may need prerequisite coursework.
Your academic program must be accredited by the Accreditation Council for Education in Nutrition and Dietetics (ACEND). There are a few ways this can look:
- Didactic Program in Dietetics (DPD): Covers the required coursework at the undergraduate or graduate level. After completing a DPD, you still need to apply separately for supervised practice (more on that below).
- Coordinated Program (CP): Bundles the academic coursework and supervised practice into a single degree program. This is the most streamlined route because you graduate ready to take the exam, without a separate internship step.
Coursework across these programs covers biochemistry, medical nutrition therapy, food science, community nutrition, and management. The exact course titles vary by university, but the competency standards are set nationally by ACEND.
Step 2: Complete Supervised Practice
Unless you’re in a coordinated program, you’ll need to complete a dietetic internship after finishing your didactic coursework. These internships provide a minimum of 1,000 hours of hands-on, supervised experience in clinical, community, and foodservice settings.
Getting into an internship is competitive. You apply through a centralized system called DICAS and then participate in a computer matching process, similar to medical residency matching. Key deadlines fall around February 1 for the spring match and September 1 for the fall match, with match registration closing roughly two weeks later. You rank your preferred programs, programs rank their preferred applicants, and the computer pairs you up.
Not everyone matches on the first try. An alternative route called the Individualized Supervised Practice Pathway (ISPP) has historically allowed unmatched applicants with a DPD verification statement to arrange supervised practice through a participating program. However, this option is being phased out for DPD graduates by December 31, 2026. Going forward, ISPP access will be limited to applicants who hold a doctoral degree.
Step 3: Pass the Registration Exam
Once you’ve completed your degree and supervised practice, you’re eligible to take the Registration Examination for Dietitians, administered by the Commission on Dietetic Registration. It’s a computer-based, multiple-choice exam that covers four content areas:
- Nutrition Care for Individuals and Groups (45%): The largest section, covering assessment, diagnosis, intervention, and monitoring of patients and populations.
- Principles of Dietetics (21%): Foundational science, including food science and nutrient metabolism.
- Management of Food and Nutrition Programs (21%): Planning, directing, and evaluating nutrition programs and services.
- Foodservice Systems (13%): Procurement, production, distribution, and food safety.
Pass rates vary widely by program. In 2024, only 43% of RD programs had a first-time pass rate of 70% or higher, and the average among those stronger programs was about 90%. Twenty percent of programs achieved a perfect 100% first-time pass rate. These numbers are worth reviewing when you’re choosing a graduate program, since the quality of your education directly affects your odds on exam day.
Step 4: Get State Licensure
Passing the national exam earns you the RD credential (sometimes listed as RDN, for Registered Dietitian Nutritionist). But in most states, you also need a state-level license or certification to practice. Forty-six states currently have their own form of credentialing for nutrition professionals. Requirements vary: some states simply verify your RD status, while others have additional applications, fees, or continuing education rules. Check with your state’s licensing board before you start seeing clients or accepting a position.
Keeping Your Credential
Registration isn’t a one-and-done achievement. You must complete 75 continuing professional education units (CPEUs) every five years to maintain your RD credential, including at least one unit in ethics or health equity. This works out to about 15 CPEUs per year, which you can earn through conferences, online courses, journal articles, and other approved activities. The five-year cycle is tracked through a Professional Development Portfolio, where you set learning goals and document your progress.
Salary and Job Growth
The median annual salary for dietitians and nutritionists was $73,850 as of May 2024, according to the Bureau of Labor Statistics. Employment in the field is projected to grow 6% from 2024 to 2034, faster than the average for all occupations. Demand is driven by the growing role of diet in managing chronic disease, an aging population, and expanded insurance coverage for nutrition counseling. RDs work in hospitals, outpatient clinics, long-term care facilities, schools, public health agencies, sports organizations, private practice, and the food industry.
