Educational and Professional Requirements
Registered Dietitian Nutritionists (RDNs) are food and nutrition experts who have met the following criteria to earn the RD credential:
- Completed a minimum of a bachelor's degree at a US regionally accredited university or college and course work accredited by the Accreditation Council for Education in Nutrition and Dietetics of the Academy of Nutrition and Dietetics.
- Effective January 1, 2024, the Commission on Dietetic Registration, the organization that administers the exam, will require a minimum of a master's degree to be eligible to take the exam. More information is available on the CDR website.
- Completed an ACEND®-accredited supervised practice program at a health-care facility, community agency, or a foodservice corporation or combined with undergraduate or graduate studies. Typically, a practice program will run six to 12 months in length.
- Passed a national examination administered by CDR. For more information regarding the examination, refer to CDR's website.
- Completed continuing professional educational requirements to maintain registration.
Some RDs hold additional certifications in specialized areas of practice. These are awarded through CDR, the credentialing agency for the Academy, and/or other medical and nutrition organizations and are recognized within the profession, but are not required. Some of the certifications include pediatric or renal nutrition, sports dietetics, nutrition support and diabetes education.
In addition to RDN credentialing, many states have regulatory laws for dietitians and nutrition practitioners. Frequently these state requirements are met through the same education and training required to become an RDN.
Dietitians study a variety of subjects, ranging from food and nutrition sciences, foodservice systems management, business, economics, computer science, culinary arts, sociology and communication to science courses such as biochemistry, physiology, microbiology, anatomy and chemistry.
Individuals who completed their education and training outside of the US, or received credentials in another country, may be eligible to become credentialed RDs in the US. Individuals who have completed the education and credentialing requirements in one country may be eligible for another country's credentialing examination if the two countries have entered into a "reciprocity" agreement to allow this. If reciprocity does not apply, you must have your academic degree validated as equivalent to the bachelor's or master's degree conferred by a US regionally-accredited college or university and complete an ACEND®-accredited supervised practice requirement to establish your eligibility to sit for the exam. It is important to note that all individuals who establish registration eligibility — whether under the provisions of a reciprocity agreement or through the combination of a validated academic degree and supervised practice program — must successfully write the Registration Examination for Dietitians to earn the RD credential.
Registered dietitians work in a wide variety of employment settings, including health care, business and industry, community/public health, education, research, government agencies and private practice.
Many work environments, particularly those in medical and health-care settings, require that an individual be credentialed as an RDN. RDNs work in:
- Hospitals, HMO's or other health-care facilities, educating patients about nutrition and administering medical nutrition therapy as part of the health-care team. They may also manage the foodservice operations in these settings, as well as in schools, day-care centers and correctional facilities, over-seeing everything from food purchasing and preparation to managing staff.
- Sports nutrition and corporate wellness programs, educating clients about the connection between food, fitness and health.
- Food and nutrition-related business and industries, working in communications, consumer affairs, public relations, marketing, product development or consulting with chefs in restaurants and culinary schools.
- Private practice, working under contract with health-care or food companies, or in their own business. RDs may provide services to foodservice or restaurant managers, food vendors and distributors or athletes, nursing home residents or company employees.
- Community and public health settings, teaching, monitoring and advising the public and helping improve their quality of life through healthy eating habits.
- Universities and medical centers, teaching physician’s assistants, nurses, dietetics students, dentists and others the sophisticated science of foods and nutrition.
- Research areas in food and pharmaceutical companies, universities and hospitals directing or conducting experiments to answer critical nutrition questions and find alternative foods or nutrition recommendations for the public.
Where to Start if You Already Have a Degree
If you already have a bachelor’s degree that is not in dietetics and are interested in becoming a registered dietitian, you should have your college transcript evaluated by a director of a dietetics program accredited by ACEND®. Because the policies, procedures and costs for the transcript evaluation may vary from one institution to another, you may want to contact more than one dietetics program for further information.
The program director will evaluate your previous academic preparation and identify the courses that you will need to complete at that school to meet the educational requirements for dietetic registration. It may be possible to complete the required dietetics coursework while enrolled in a graduate program. The dietetics program director can advise you of your options.
Once the required coursework is completed, you are eligible to apply to an ACEND®-accredited supervised practice program.
Salaries and Job Outlook
According to the Academy's 2021 Compensation and Benefits survey of the Dietetics Profession, the median full-time salary of all RDNs equates to $70,000 per year. As with any profession, salaries and fees vary by region of the country, employment settings, scope of responsibility and supply of RDs. Salaries increase with years of experience and RDNs, in management and business, may earn incomes above $90,000. For more information, see the Academy of Nutrition and Dietetics 2021 Compensation and Benefits Survey of the Dietetics Profession.
According to the US Bureau of Labor Statistics, employment of dietitians is projected to grow 8% from 2019-2029, much faster than average for all occupations, because of the increased emphasis on the role of food and nutrition in preventing and treating diseases, a growing and aging population and public interest in nutrition.
There are many resources to help students in need pay for college. You may be able to obtain a grant or scholarship from a corporation, community or civic group, philanthropic or religious organization or directly from the school or college you are interested in attending. Federal grants and low-interest loans may also be available.
The Academy of Nutrition and Dietetics Foundation offers scholarships to encourage eligible students to enter the field of dietetics. Student members of the Academy enrolled in their junior year in an ACEND®-accredited program may apply for a Foundation scholarship. Scholarships are also available for student members in ACEND®-accredited dietetic internships and graduate studies. Contact the Academy's Foundation Team (firstname.lastname@example.org) for Foundation scholarship information.
