Becoming a Registered Dietitian Nutritionist (RDN) requires a master’s degree from an ACEND-accredited program, at least 1,000 supervised practice hours, and passing the CDR credentialing exam. As of January 1, 2024, the master’s degree is mandatory for all new RDNs. Integrated programs often take two to three years, but the total time varies depending on prerequisites and pathway.

Step 1 — Complete the Science Prerequisites

Before applying to any ACEND-accredited graduate program, you need a foundation in the hard sciences. Programs typically require coursework in general chemistry, organic chemistry, microbiology, anatomy and physiology, nutritional biochemistry, and statistics. Competitive GPA expectations vary by program, but most look for strong academic performance, especially in science coursework.

If you’re coming from a non-science background, you can complete these prerequisites at a community college or through a post-baccalaureate program before applying to graduate school.

Step 2 — Choose Your Pathway and Earn a Master’s Degree

As of January 1, 2024, all new RDNs must hold a master’s degree from an ACEND-accredited program. A bachelor’s degree alone no longer qualifies a candidate to sit for the CDR exam.

There are two main ways to satisfy both the degree and supervised practice requirements at the graduate level. A Graduate Program (GP), also called the Future Education Model (FEM), integrates master’s coursework and at least 1,000 supervised practice hours into a single degree. A Coordinated Program (CP) works similarly and is available at both the bachelor’s and master’s levels. Both types include supervised practice in the degree, so you don’t need to apply for it separately through the DICAS match. The program types section below explains each option in detail.

Step 3 — Complete 1,000+ Hours of Supervised Practice

ACEND requires a minimum of 1,000 supervised practice hours for RDN eligibility. Most supervised practice must be completed in real-world settings, including hospitals, outpatient clinics, community health organizations, school nutrition programs, or food service operations, though some programs may allow limited simulation or telehealth experiences.

If you enroll in a GP or CP program, supervised practice is built into the degree. If you follow the traditional DPD track, which produces a bachelor’s-level Verification Statement, you’ll need to apply separately for a standalone Dietetic Internship (DI) through the DICAS matching system, or find an ISPP program that lets you arrange your own qualifying site.

Step 4 — Pass the CDR Credentialing Exam

Once you’ve completed your degree and supervised practice requirements, you’re eligible to sit for the Commission on Dietetic Registration (CDR) national exam. The exam tests clinical nutrition competency across a broad range of domains. Candidates who pass receive the RD or RDN designation. The two titles are legally interchangeable.

Step 5 — Apply for State Licensure

The RDN credential is national, but the legal right to practice and use protected professional titles is governed by state law. Most states require a separate state license or registration before you can provide professional individualized nutrition counseling or medical nutrition therapy. Requirements vary significantly by state, so confirm your state’s specific rules before you finalize your program decision. The state licensure section below covers this in more detail.

Step 6 — Maintain Your Credential

The CDR requires 75 continuing professional education units (CPEUs) every five years to maintain active registration. RDNs who want to specialize in sports nutrition, oncology, pediatrics, renal care, or other areas can pursue additional board certifications from the CDR. Each requires documented specialty practice hours and a separate exam.

Not Sure the RD Track Is Right for You?

Did You Actually Mean Nutritionist or a Different Credential?

The term “nutritionist” covers a wide range of credentials. Not everyone who lands on this page is aiming for a career in clinical dietetics. Here’s a quick guide to help you decide.

• RD / RDN path — You want to work in clinical settings, bill Medicare or private insurance for Medical Nutrition Therapy, or hold a hospital or healthcare system position. This is the page for you.
• CNS path (Certified Nutrition Specialist) — You want a functional or integrative nutrition practice, often in private-pay settings. The CNS requires a master’s or doctoral degree and 1,000 supervised hours, but follows the BCNS track rather than the ACEND/CDR track. Some states recognize the CNS for clinical licensure alongside the RDN.
• NDTR path (Dietetic Technician, Registered) — You want to enter the field sooner with an associate degree and work in a supporting role under an RDN in hospitals or food service.
• Health or wellness coaching — You want to support clients in general wellness without conducting clinical diagnoses or providing treatment. This track doesn’t require graduate-level training or ACEND accreditation, and it typically doesn’t allow insurance billing or MNT in regulated states.

If you’re leaning toward the CNS or a holistic path, explore non-RD nutrition pathways here.

What are the steps to becoming a registered dietitian now?

The pathway has six core stages: complete science prerequisites, earn a master’s degree from an ACEND-accredited program, finish at least 1,000 supervised practice hours, pass the CDR credentialing exam, apply for state licensure, and maintain the credential through continuing education. The sequence is fixed. You can’t sit for the CDR exam without completing the degree and practice hours first.

Do I need a master’s degree to become an RD or RDN?

Yes. As of January 1, 2024, the CDR requires a master’s degree from an ACEND-accredited program for all new RDNs. A bachelor’s degree alone no longer qualifies a candidate to sit for the national credentialing exam. If you’re starting your path now, build your plan around the master’s requirements from the beginning.

Do I need an ACEND-accredited program?

Yes. ACEND is the Accreditation Council for Education in Nutrition and Dietetics, the primary programmatic accreditor recognized by the CDR for RDN eligibility. If your program isn’t ACEND-accredited, its coursework typically won’t satisfy CDR requirements for the national exam, regardless of the school’s overall institutional reputation. Always verify current ACEND status at eatrightpro.org before enrolling, not just on the school’s website.

Where does the internship fit in the process?

The Dietetic Internship (DI) is the supervised practice component of the traditional DPD pathway. It’s a standalone program of at least 1,000 hours applied for separately through the DICAS matching system after completing a degree. If you enroll in a Graduate Program (GP/FEM) or Coordinated Program (CP), supervised practice is integrated directly into the degree. You don’t need to apply separately. That’s one of the key reasons GP and CP programs have become the preferred route for career changers and working adults.

How long does the whole process take?

Integrated programs often take two to three years post-bachelor’s, but total time varies depending on prerequisites and pathway. The timeline is longer if prerequisites still need to be completed, or if you follow the traditional DPD route and then apply separately for a dietetic internship. Someone starting from scratch can expect a total journey of 4 to 6 years from first course to credential, though individual situations vary.

What if I actually meant nutritionist rather than RD?

That’s a common situation. The term “nutritionist” is used broadly and doesn’t point to a single credential. If you’re interested in clinical practice, insurance billing, or hospital roles, the RDN is the right path. If you’re drawn to functional or integrative nutrition, private-pay practice, or holistic health, the CNS credential may be a better fit. The decision box above covers the main tracks in plain language, and the handoff cards at the bottom of this page link to the right guide for each.

What is the Future Education Model (FEM), and should I look for it?

The Future Education Model is ACEND’s name for integrated Graduate Programs (GP) that combine a master’s degree with at least 1,000 supervised practice hours in a single enrollment. FEM programs typically accept any bachelor’s degree, not just a DPD nutrition degree, as long as you’ve completed the required science prerequisites. Supervised practice placement is built directly into the degree. You bypass the traditional DICAS match entirely.

Can I complete the RDN pathway entirely online?

You can complete all didactic coursework online through many ACEND-accredited programs. Most supervised practice hours must be completed in real-world settings, such as hospitals, clinics, or community health organizations, though some programs may allow limited simulation or telehealth experiences. The advantage of an online program is that you’re not tied to clinical sites near a campus. Most working adults arrange supervised practice in their own community.

What salary can I expect as an RDN?

According to May 2024 data from the Bureau of Labor Statistics, the median annual wage for dietitians and nutritionists was $73,850. The lowest 10 percent earned less than $48,830, and the top 10 percent earned more than $101,760. Earnings vary by setting, specialty, geographic location, and years of experience. RDNs with advanced board certifications, or those in private practice, often earn well above the general median.

Key Takeaways

What to Know Before You Start the RDN Pathway

• As of January 1, 2024, all new RDNs must hold a master’s degree from an ACEND-accredited program. A bachelor’s degree alone no longer qualifies you for the CDR exam.
• ACEND accreditation is program-specific, not institution-wide. Verify current “Accredited” status at eatrightpro.org before enrolling, not on the school’s website.
• Graduate Programs (GP/FEM) and Coordinated Programs (CP) integrate supervised practice into the degree. No separate DICAS match required. This is the preferred route for working adults and career changers.
• Online ACEND programs deliver coursework remotely. Most of the required 1,000+ supervised practice hours must be completed in person in a qualifying setting, though some programs may allow limited simulation or telehealth experiences.
• Career changers can enter GP/FEM programs directly with any bachelor’s degree, provided the science prerequisites are complete. No DPD Verification Statement required on this track.
• State licensure rules vary. Earning the RDN credential doesn’t automatically grant identical practice rights in every state. Confirm your state’s requirements before you enroll.
• If the RD path isn’t the right fit, the handoff cards below link to the CNS/holistic track, internship details, and online program options.
