Professionals drawn to a career at the intersection of public health, food science and clinical practice may want to explore Arkansas State University’s online Master of Science (M.S.) in Nutrition and Dietetics RD Track program. Designed for those interested in earning the registered dietitian (RD) credential, the ACEND-accredited program offers a direct route to examination eligibility and a rewarding career in a growing field.
Issued by the Commission on Dietetic Registration (CDR), the RD — also known as the registered dietitian nutritionist (RDN) credential — is a nationally protected designation that distinguishes its holders from the largely unregulated world of nutrition coaching and wellness advising. Earning it requires verified education, supervised practice and a passing score on a national examination.
What is the Job Outlook for RDNs?
Data from the U.S. Bureau of Labor Statistics (BLS) shows the median annual wage for dietitians and nutritionists was $73,850 as of May 2024, however salaries vary based on geography, level of experience and workplace setting. Professionals in management, education and research positions earn considerably more.
Employment in the field is projected to grow 6% between 2024 and 2034, which is faster than the average for all occupations per BLS. Roughly 6,200 openings are expected each year over the decade, making the career path an exceptional opportunity for those passionate about improving public health, leading nutrition services and driving meaningful change across communities.
Do RDNs Need a Master’s Degree?
The path to the RDN credential recently became more rigorous. Effective January 1, 2024, CDR raised the minimum degree requirement for examination eligibility from a bachelor’s degree to a graduate degree. All other didactic and supervised practice requirements remained the same. The change applies only to those seeking to become eligible for the registration examination for the first time on or after January 1, 2024. Individuals who established eligibility on or before December 31, 2023, or those already registered, are not required by CDR to obtain a graduate degree.
Advanced education connects directly to expanded scope of practice and greater earning potential. A-State’s ACEND-accredited M.S. in Nutrition & Dietetics – RD track can be completed in as few as 24 months entirely online, offering aspiring dietitians a flexible pathway to meeting the new graduate-level requirement.
Understanding the Five Steps to Becoming a Registered Dietitian
There is a five-step process to earning the RDN credential. A-State’s nutrition and dietetics master’s program integrates steps one and two into its curriculum, eliminating the need to secure a separate internship placement. The steps follow this defined sequence:
- Candidates must complete an ACEND-accredited graduate program covering required didactic coursework: food and nutrition sciences, community nutrition, medical nutrition therapy and related areas.
- Students must log supervised practice hours through an ACEND-accredited dietetic internship, coordinated program, graduate program or individualized supervised practice pathway.
- Candidates must pass the CDR “Registration Examination for Dietitians.”
- Aspiring RDNs must satisfy state licensure requirements. (All states accept the RDN credential for this purpose.)
- Graduates must maintain the credential by completing 75 hours of continuing professional education every five years.
How Long Does It Take to Earn an RD Designation?
Graduate programs that combine didactic coursework with supervised practice typically take two to three years to complete. A-State’s program can be finished in as few as 24 months, with part-time enrollment available for working professionals.
Prospective students should first confirm that prerequisite undergraduate courses are complete. If any interested person is lacking in that regard, A-State offers the courses online as well to ensure no one feels unprepared to embark on the journey.
What to Expect on the RD Exam
The CDR Registration Examination is administered year-round by Pearson VUE testing centers across the country. The test uses a computer-adaptive format and incorporates the updated content outline that took effect January 1, 2022.
In March 2024, CDR extended the test window to three hours to reduce time pressure on candidates. Those who do not pass on their first attempt can access a second attempt at a discounted rate through CDR’s “test bundle voucher.”
Candidates who pass receive their score report before leaving the test center. Graduate coursework and supervised practice hours form the backbone of exam preparation, though CDR-approved supplemental study resources are also available.
Begin Your Journey to a Fulfilling Career as an RDN
CDR’s graduate degree requirement is new enough that candidates who begin now will be ahead in a field that is still adapting to the change. With job growth outpacing the national average, the RDN credential carries measurable, durable career value.
