Four Oregon institutions offer nutrition degrees: Oregon State in Corvallis, Oregon Health & Science University in Portland, and two graduate-focused schools also based in Portland, the University of Western States and the National University of Natural Medicine. Oregon State and OHSU hold the state’s ACEND-accredited routes to the RD credential, and three of their master’s-level routes build supervised practice directly in. Western States and NUNM offer functional, clinical, and culinary nutrition degrees that do not lead to the RD exam. There is no associate-level nutrition degree in the state, so every path starts at the bachelor’s.
Oregon State runs the only ACEND-accredited undergraduate dietetics program in Oregon, and it is the only entry point toward the RD credential for someone starting from high school. OHSU restructured its graduate programs in 2026: its plain M.S. in Human Nutrition is now itself an ACEND Coordinated Program with supervised practice built in, no longer the non-accredited research-only track it once was. Both universities offer accredited graduate routes that include supervised practice, so the choice at graduate level is between real options at each school rather than one path per school.

Costs are estimates for tuition and exclude fees and housing. Oregon State runs on quarter terms, so 180 quarter credits equal 120 semester credits. Non-resident on-campus rates at Oregon State are not shown here; confirm them directly. Verify all current rates with each school before applying.
Which Oregon Nutrition Program Fits You
Choose Oregon State if you are starting from high school. Its Dietetics option is the only ACEND-accredited undergraduate dietetics program in the state, so no other Oregon school can take a beginner toward the RD credential. The Nutrition BS also carries non-dietetics options for students heading to medicine, research, or food systems work.
Choose Oregon State’s Ecampus routes if cost or location is the constraint. Online tuition is a flat $409 per credit for undergraduates regardless of residency, with no non-resident premium — unusual among public flagship universities. The MS in Advanced Dietetics is delivered online as well.
Choose OHSU if you want a hospital-network-based master’s in Portland. It is Oregon’s only academic health center, and as of a 2026 restructuring it offers two accredited routes: a Coordinated Program (its former standalone MS, now itself ACEND-accredited with 1,014 built-in practice hours) and a newer MS in Food Systems and Society with Dietetic Internship (72 credits, 1,056 hours, a reported 100 percent first-time RD exam pass rate for 2024). Rotations span a 300-plus site network across Oregon, not just OHSU Hospital.
Choose Western States or NUNM if you want functional, clinical, or culinary nutrition rather than the RD credential. Neither has an ACEND program. Western States is fully online and built around functional medicine. NUNM offers clinical and culinary concentrations that can be taken in person in Portland or online, and its Clinical concentration is accredited by ACNPE, the accreditor tied to the Certified Nutrition Specialist exam. Both leave the 1,000 supervised hours that credential requires for the student to arrange.
Oregon Nutrition Schools
Oregon State University
OSU’s School of Nutrition and Public Health in Corvallis anchors nutrition education in Oregon and covers every level from bachelor’s through supervised practice.
- BS Nutrition — 180 quarter credits, with three options: Dietetics (the accredited DPD), Nutrition and Health Sciences, and Nutrition in Foodservice, Culinary and Food Systems (itself split into a culinary track and a food systems track)
- MS Nutrition – Professional Dietetics (MS-PD) — online coursework via Ecampus with in-person rotations in Oregon, minimum 1,000 supervised practice hours, about 22 months
- MS Nutrition – Advanced Dietetics — online, requires an existing RDN credential or a DPD verification statement, not for career changers without prior credentials
- Dietetic internship — non-credit, non-degree, 9.5 months full-time from September through June, with 56 or more preceptors, requiring a DPD verification statement and a completed graduate degree already in hand
The MS-PD is the differentiator: it satisfies the CDR master’s requirement and the supervised practice requirement together, with coursework online and rotations in-state. OSU reports its DPD sits at the 97th percentile nationally for first-time RDN exam performance.
The MS-PD cohort is small — OSU has published an intake of up to 12 students. Treat admission as competitive and have a second route in mind. The culinary track within the Foodservice, Culinary and Food Systems option integrates coursework at Linn-Benton Community College, so check how that affects your schedule.

Oregon Health & Science University
OHSU in Portland offers graduate nutrition study only, through its School of Medicine, and is the state’s only academic health center. It restructured its programs in 2026.
- MS in Human Nutrition, Coordinated Program — 54 credits, 2 years full-time only, 1,014 supervised practice hours built in, thesis or capstone; now ACEND-accredited as a Coordinated Program (this is a 2026 change from a prior 45-credit, non-accredited standalone MS)
- MS in Food Systems and Society with Dietetic Internship — 72 credits (50 MS plus 22 DI), two years, 1,056 supervised practice hours, a reported 100 percent first-time RD exam pass rate for 2024
- Dietetic internship graduate certificate — 22 credits, 9 months, for applicants who already hold or are enrolled in a graduate degree
The curriculum is science-heavy, covering nutrient metabolism, nutritional epidemiology, and biostatistics, with medical nutrition therapy and research methods in the internship-bearing tracks. Clinical rotations span more than 300 sites across Oregon, including OHSU Hospital, VA Portland Health Care System, and community and rural sites in Bend, Medford, and Klamath Falls, not OHSU Hospital alone.
All three current tracks lead toward the RDN, a change from the program’s earlier structure where the standalone MS carried no supervised practice. Admission across all three asks for a 3.0 GPA minimum and three letters of recommendation; the Coordinated Program accepts prerequisite coursework in place of a completed DPD, while the other two tracks require a DPD verification statement.

University of Western States
Western States in Portland runs its nutrition degrees through the College of Graduate Studies, entirely online, and none leads to RD eligibility.
- M.S. Clinical Nutrition and Functional Medicine — 56 quarter credits, renamed in fall 2026 from Human Nutrition and Functional Medicine, run with the Institute for Functional Medicine
- Graduate Certificate, Clinical Nutrition and Functional Medicine — 30 quarter credits
- Doctor of Clinical Nutrition — 65 quarter credits, fall start only
The M.S. is designed to meet the coursework requirements for the Certified Nutrition Specialist exam, but the degree is not accredited by ACNPE and the 1,000 supervised hours are completed outside it. Western States has no ACEND program, and its FAQ says the M.S. satisfies only the master’s-degree step for people who already hold an ACEND-accredited dietetics bachelor’s.
Full University of Western States profile
National University of Natural Medicine
NUNM in Portland offers nutrition through its School of Undergraduate and Graduate Studies, with in-person and online options. Its catalog lists no ACEND accreditation.
- M.S. Nutrition, Clinical concentration — accredited by ACNPE, with initial accreditation listed in June 2025
- M.S. Nutrition, Culinary concentration — food-focused, with no programmatic accreditation stated and not CNS-eligible
- Accelerated B.S. to M.S. Nutrition — 3 years
- B.S. Nutrition
Both master’s concentrations are priced at $538 per credit for all students. The program page says 70 credits while the catalog and tuition tables show 66, so confirm the total with the school.

How to Choose a Nutrition Program in Oregon
Where you enter decides the school
Oregon has one undergraduate door and two graduate ones. If you are starting out, Oregon State is the only accredited option; if you already hold a bachelor’s, both universities compete for you. Someone holding a DPD verification statement and a master’s can also apply to OSU’s standalone internship. Western States and NUNM sit outside the RD route, so they suit people aiming for the Certified Nutrition Specialist credential or for work that does not require a license.
Online coursework, in-person practice
Both of OSU’s graduate dietetics routes deliver coursework online while keeping supervised practice in person and in Oregon. OHSU is campus based in Portland. If you need to stay employed while studying, OSU Ecampus is the flexible option and the flat per-credit rate makes it viable from outside the state. Western States is entirely online, and NUNM offers an online option for its master’s.
The master’s requirement changed in 2024
Since January 1, 2024, the Commission on Dietetic Registration has required a master’s degree in any field, plus a verification statement from an ACEND-accredited program, to sit for the RDN exam. Supervised practice runs to at least 1,000 hours. An Oregon State bachelor’s alone no longer qualifies anyone, so plan the graduate step from the start.
Nutrition Licensure and Credentials in Oregon
Oregon licenses dietitians through the Board of Licensed Dietitians, part of the Oregon Health Authority’s Health Licensing Office. Initial application runs about $110, licences are valid one year, and renewal is around $60. Licensees complete 15 continuing education hours each licensure year, plus one hour of cultural competency education at alternating renewals.
One scope note matters: the board oversees licensed dietitians but does not regulate people practising as nutritionists in Oregon. The title and the licence are not the same thing, so check which one a job posting actually requires. Confirm current fees and rules with the Health Licensing Office before relying on them.
Full profiles for all four Oregon schools are linked above. Before applying, verify three things directly with the school: that the specific degree option you are entering carries current ACEND accreditation, that the tuition rate quoted matches the coming academic year (OHSU’s programs changed materially in 2026), and — for OSU’s MS-PD in particular — what the cohort size and application deadline are for your intended start.
