Quick Answer

Becoming a registered dietitian means completing an ACEND-accredited degree, finishing a supervised internship of about 1,000 hours, and passing the Commission on Dietetic Registration exam. As of 2024, new dietitians must hold a graduate degree before sitting for that exam. Many states also require a license. The median wage is $73,850 a year, and the "registered dietitian" credential is legally protected in a way that "nutritionist" often is not.

There are two questions hiding inside "how to become a registered dietitian," and both matter before you choose this path. The first is whether an RD is actually different from a nutritionist, because the two words get used interchangeably even though they are not the same thing. The second is how the recent change to the education requirement, which now demands a graduate degree, affects the time and cost of getting there.

Here is the distinction that shapes everything: registered dietitian is a protected, regulated credential earned through a specific accredited path, while in many states anyone can call themselves a nutritionist with no training at all. If you want to work in hospitals, provide medical nutrition therapy, or bill insurance, you almost always need the RD. That credential is what this guide is about, and the path to it changed meaningfully in 2024.

The Bureau of Labor Statistics projects 6% growth for dietitians and nutritionists from 2024 to 2034, faster than the average for all occupations, with about 6,200 openings each year1. Demand is supported by the role of nutrition in managing chronic disease and by an aging population.

If you are drawn to the health-and-prevention side of this work, it pairs naturally with a public health degree, and the science foundation overlaps with a biology degree.

Expert Tip

Plan for the graduate degree from the start. As of 2024, the Commission on Dietetic Registration requires a master's degree before you can take the registration exam, so the old bachelor's-only route is closed to new entrants. Just as important, the supervised internship is a competitive match, and applicants who line up strong grades, volunteer experience, and relevant work early have a far easier time securing a placement.

What Does a Registered Dietitian Actually Do?

Registered dietitians translate nutrition science into practical care, and the setting determines what that looks like day to day.

Clinical dietetics. In hospitals and clinics, you assess patients, design medical nutrition therapy for conditions like diabetes, kidney disease, and cancer, and work as part of a medical team. This is the largest employer of RDs.

Community and public health. You run nutrition programs, counsel populations, and work on prevention through schools, government programs, and nonprofits.

Food service management. You oversee nutrition and food operations in hospitals, schools, or institutions, blending nutrition expertise with management.

Private practice and sports. You counsel clients directly, work with athletes, or build a specialty practice, often after gaining experience elsewhere.

Important

Do not confuse "nutritionist" with "registered dietitian." In many states the word nutritionist is unregulated, which means someone can use it after a weekend course or no training at all. The RD credential requires an accredited degree, a supervised internship, a national exam, and now a graduate degree, and it is what hospitals and insurers recognize. Pay is moderate for the length of the path, so go in knowing the credential, not the title, is what carries professional weight.

Education Requirements

An ACEND-accredited degree. Your coursework must come through a program accredited by the Accreditation Council for Education in Nutrition and Dietetics, covering food science, biochemistry, physiology, and medical nutrition therapy.

A graduate degree, now required. As of 2024, new registered dietitians must hold a master's degree before taking the registration exam2. Many students meet this through a combined or coordinated program that pairs the graduate degree with the required supervised practice.

A supervised internship. You complete roughly 1,000 hours of supervised practice, historically called a dietetic internship, which is a competitive match.

The CDR exam and state licensure. You pass the Commission on Dietetic Registration exam to earn the RD credential, and many states also require a license to practice23.

The Step-by-Step Path

  1. Complete an ACEND-accredited degree. Build the science and nutrition foundation the credential requires.
  2. Earn the required graduate degree. A master's is now mandatory for new dietitians, often through a coordinated program.
  3. Match to and complete a supervised internship. About 1,000 hours of supervised practice, secured through a competitive process.
  4. Pass the CDR registration exam2.
  5. Get a state license where required.
  6. Specialize if you want. Areas like renal, pediatric, or sports nutrition can raise pay and open doors.

How Dietitian Pay Varies

The median is $73,850, ranging from under $48,830 at the bottom tenth to more than $101,760 at the top1. Setting, geography, and specialization drive the spread. Clinical roles and specialized certifications tend to pay above community and outpatient work, and private practice income depends heavily on how you build the business. For the length of the path, the pay is moderate, which is worth weighing honestly against graduate-school cost.

Registered Dietitian vs Nutritionist

This is the single most important thing to understand before you commit. A registered dietitian has completed an accredited degree, a graduate degree, a supervised internship, and a national exam, and the title is protected. A nutritionist, in many states, is an unregulated title that carries no required training, though some states do license certified nutrition specialists with their own credentials. If your goal is to work in a hospital, provide medical nutrition therapy, or bill insurance, the RD is almost always necessary. If you want to coach general wellness outside of clinical settings, the requirements are looser but so is the professional standing. Knowing which role you actually want saves years of misdirected effort.

What to Major in to Become a Dietitian

Because the registered dietitian credential now requires a graduate degree, your undergraduate choices set up a longer path, and planning them well saves both time and money.

The cleanest route is an undergraduate program accredited by the Accreditation Council for Education in Nutrition and Dietetics, often a bachelor's in nutrition or dietetics. Choosing an accredited program from the start means your coursework counts toward the credential and you are not scrambling to add missing requirements later. If your school does not offer an accredited nutrition major, a science-heavy field like a biology degree can work as long as you complete the specific nutrition and science courses the graduate path requires.

Watch the graduate-degree requirement closely, because it reshaped the timeline for everyone entering the field after 2024. Many students now choose a coordinated program that combines the required master's with the supervised practice hours, which is usually more efficient than treating them as separate steps. Mapping out how you will satisfy the accredited degree, the graduate degree, and the supervised practice as a single plan, rather than three disconnected hurdles, is the difference between a six-year path and a stretched-out one.

Start building relevant experience early. Volunteering in a hospital nutrition department, working in food service, or helping with a community nutrition program all strengthen your application to the competitive supervised-practice match and help you confirm which setting appeals to you. Clinical dietetics, community nutrition, and food-service management are quite different day to day, and the sooner you know which pulls at you, the more focused your training becomes. Students drawn to the population side often pair their plan with coursework or a minor in public health.

Be realistic about the money before you commit. Dietetics now requires a graduate degree for a median salary of $73,850, which is moderate for that level of education. That does not make it a poor choice, since the work is stable and meaningful and the credential is genuinely protected, but it does mean you should compare graduate program costs carefully and lean toward affordable, accredited options. A large loan balance against a moderate salary is the main way this career disappoints people, and it is almost always avoidable with early planning.

Finally, keep the distinction between the credential and the title in front of you the whole way. Everything in this path exists to earn the registered dietitian credential, which is what employers and insurers recognize. If at some point you decide you want to coach general wellness rather than practice clinically, you can step off the path knowingly, but do not drift off it by accident and end up with the education yet not the credential that makes it pay.

Frequently Asked Questions

How long does it take to become a registered dietitian?

Plan on about six years now that a graduate degree is required. That is roughly four years for an accredited bachelor's plus a master's, along with the supervised internship, which is often built into a coordinated graduate program.

Is a registered dietitian the same as a nutritionist?

No. Registered dietitian is a protected credential earned through an accredited degree, a graduate degree, a supervised internship, and a national exam. In many states, nutritionist is an unregulated title with no required training. The RD is what hospitals and insurers recognize.

Do you need a master's degree to become a dietitian?

Yes, for new entrants. As of 2024, the Commission on Dietetic Registration requires a graduate degree before you can take the registration exam. The previous bachelor's-only path is no longer open to new dietitians.

How much do registered dietitians make?

The median wage is $73,850 a year, ranging from under $48,830 to more than $101,760 depending on setting, specialization, and location. Clinical and specialized roles tend to pay above community nutrition work.

Is becoming a registered dietitian worth it?

It depends on your goals. If you want to work clinically, provide medical nutrition therapy, or hold a recognized credential, the RD is necessary and the career is stable. Because the pay is moderate for a path that now requires a graduate degree, weigh the education cost carefully before committing.

What can you do with a nutrition degree that is not the RD?

A nutrition or biology degree can lead into public health, wellness coaching, food industry roles, research, or further study in medicine and related fields. Just know that without the RD you generally cannot practice as a clinical dietitian or bill insurance for medical nutrition therapy.

Can you become a dietitian with an online degree?

Partly. Some accredited coursework and graduate programs are offered online, but the supervised practice hours must be completed in person at approved sites. Confirm that any online program is accredited by the Accreditation Council for Education in Nutrition and Dietetics before enrolling, because only accredited coursework counts toward the registered dietitian credential.
