Metro Phoenix holds most of Arizona’s nutrition education. Four institutions grant nutrition degrees here: Arizona State University in Downtown Phoenix, Grand Canyon University in west Phoenix, Sonoran University of Health Sciences in Tempe, and Paradise Valley Community College in north Phoenix. Several other Maricopa colleges offer an identical transfer associate degree, and resident costs run from $97 per credit at the community colleges to $763 per credit at Sonoran.
Two Phoenix programs lead to the RDN credential, and they are structured differently: ASU’s M.S. with a dietetic internship, and GCU’s online M.S. as an ACEND Future Education Model program that needs no separate internship match. Sonoran is the metro’s only route to the Certified Nutrition Specialist credential, which is a different profession from dietetics. Paradise Valley trains dietetic technicians (NDTR), and the Maricopa associate degree is a transfer pathway that carries no credential of its own.

Which Phoenix Nutrition Program Fits You
Choose Arizona State if you want a dietetic internship with a specialty built in. Its M.S. with Dietetic Internship runs a VA track based at the Phoenix VA, a sports nutrition rotation with paid foodservice work, and a funded maternal-child health traineeship. It is also the only Phoenix school offering the full undergraduate-through-graduate dietetics ladder on one campus.
Choose Grand Canyon if you are changing careers and need the coursework online. Its M.S. accepts a bachelor’s in any field with prerequisites, builds 1,000 practice hours into seven of its eight courses, and requires no DPD verification statement. Confirm its ACEND status before applying, because GCU’s own pages disagree on candidate versus accredited.
Choose Sonoran if the CNS credential is the goal rather than the RDN. Its M.S. in Applied Clinical Nutrition is built to cover both the coursework and the supervised practice the Board for Certification of Nutrition Specialists requires, and both nutrition master’s degrees run fully online. Nothing at Sonoran is ACEND-accredited, so this is not a dietitian pathway.
Choose Paradise Valley if you want a registered credential at community college prices. The program director arranges every practicum site, there is no competitive application, and the whole A.A.S. costs less than one year at a state university. Graduates sit for the NDTR exam, not the RD exam.
Start at a Maricopa college if you are still completing prerequisites. The A.A. with an emphasis in Nutritional Science is aligned to ASU’s B.S. in Dietetics and B.S. in Nutritional Science, so it functions as the first two years of either. It is a transfer degree, and on its own it qualifies you for nothing in nutrition.
Phoenix Nutrition Schools
Arizona State University
ASU’s College of Health Solutions in Downtown Phoenix offers six nutrition degrees plus an ACEND dietetic internship, on campus and online.
- B.S. Dietetics (DPD), B.S. Nutritional Science, B.S. Applied Nutrition and Health: $57.6K resident, 120 credits, 4 years
- B.A.S. Applied Nutrition and Health: online, for associate degree holders
- M.S. Nutritional Science and online M.S. Medical Nutrition: 30 credits each
- M.S./DI: $30.0K resident, 2 years standard or 16 months on the VA track, about 1,100 supervised hours
Only the B.S. Dietetics and the internship carry ACEND accreditation, and none of ASU’s online nutrition degrees is an RD pathway. Applications to the M.S./DI run through DICAS with a January 15 deadline, and the VA track starts each January.
Full Arizona State University profile
Grand Canyon University
GCU’s College of Natural Sciences in west Phoenix pairs a campus bachelor’s with an online master’s that leads toward the RDN.
- B.S. Nutritional Sciences: $66.0K, 120 credits, 4 years, campus
- M.S. Nutrition and Dietetics: $18.3K at $610 per credit, 30 credits, 1,000 practicum hours
The M.S. is an ACEND Future Education Model graduate program, so it needs neither a DPD nor a separate internship match. The B.S. carries dietetics-style coursework but is not accredited on its own, and GCU’s program page does not explain how practicum sites are arranged.

Sonoran University of Health Sciences
Sonoran, formerly Southwest College of Naturopathic Medicine, runs a College of Nutrition from its Tempe campus and teaches all three nutrition master’s degrees online.
- M.S. Clinical Nutrition: 54 credits (36 didactic, 3 lab, 15 clinical), about $41.2K at $763 per credit
- M.S. Applied Clinical Nutrition: 64 credits (36 didactic, 3 lab, 25 clinical), about $48.8K
- Executive M.S. Nutrition Business Leadership: aimed at the natural products industry
The Applied Clinical Nutrition degree adds a six-month clinical practicum that the Clinical Nutrition degree does not include, and Sonoran markets it as covering the full 1,000-hour supervised practice requirement for CNS certification. The university holds institutional accreditation from the Higher Learning Commission, which the certifying board requires, but no Sonoran nutrition program is ACEND-accredited.
Sonoran’s catalog lists 25 clinical credits and 900 clinical hours for that degree, while its program materials describe the full 1,000 hours, so ask admissions how the remaining hours are counted. A full profile of this school is pending.
Paradise Valley Community College
PVCC in north Phoenix offers the Maricopa district’s ACEND-accredited technician degree, now that Chandler-Gilbert no longer runs it.
- A.A.S. Nutrition and Dietetic Technology: $6.3K resident at $97 per credit, 65 to 82 credits, 5 terms full time, 466 supervised hours
The program director and faculty arrange every practicum site, and there is no competitive application to enter. Graduates of an accredited dietetics bachelor’s can reach NDTR eligibility here by completing the practicum hours alone.

Maricopa Community Colleges
The district’s Associate in Arts with an Emphasis in Nutritional Science, plan code 8115, is one degree taught at colleges across the Valley, including Mesa, Chandler-Gilbert, Estrella Mountain, South Mountain, and online through Rio Salado.
- 60 to 64 credits, about $5,800 to $6,200 in resident tuition at $97 per credit
- Aligned to ASU’s B.S. in Dietetics and B.S. in Nutritional Science
- A grade of C or better is required in every course
Because it is a single district-wide plan, the college you pick changes the campus and the schedule rather than the curriculum. Maricopa notes that students may need to take courses at more than one college to finish the emphasis.
How to Choose a Nutrition Program in Phoenix
Decide the credential before the school
Phoenix is one of the few metros where three different nutrition credentials are taught at once: the RDN at ASU and GCU, the CNS at Sonoran, and the NDTR at Paradise Valley. These are separate professions with separate accreditors, and coursework does not transfer between the routes. Picking the wrong one costs years, which is the single most common mistake this page exists to prevent.
Ask who arranges supervised practice
Every credential here requires hours in a real facility, and the programs differ on who finds it. ASU places interns through its own rotations including the Phoenix VA, and Paradise Valley’s director assigns all 466 technician hours, while GCU does not publish how its 1,000 online-program hours get placed. Living in the Valley helps in all three cases, because the sites are here.
Compare cost architecture, not sticker price
Arizona’s public tuition splits sharply by residency: ASU’s bachelor’s runs $57.6K for residents and $154.3K for everyone else, and Paradise Valley charges out-of-state students living in Arizona nearly four times the resident rate. The private schools charge one rate, which makes GCU’s $18.3K master’s and Sonoran’s $41.2K to $48.8K degrees look very different depending on where you live now. Community college prerequisites at $97 per credit are the cheapest credits available in the metro.
Check whether online means online
Sonoran’s nutrition degrees and ASU’s B.A.S. and M.S. Medical Nutrition are genuinely online, and Rio Salado teaches the transfer associate online. GCU’s master’s is hybrid in practice, since the coursework is online but the practicum is in person. Any program leading to a credential will put you in a facility eventually.
Match your starting point
High school graduates and career changers without a science background start at a Maricopa college or in an ASU or GCU bachelor’s. Career changers who already hold a bachelor’s can enter GCU’s M.S. or Sonoran’s master’s after prerequisites, with no DPD required. ASU’s M.S./DI is the one Phoenix RD program that requires a DPD verification statement first.
Nutrition Licensure and Credentials in Arizona
Arizona does not license dietitians or nutritionists. A licensure bill passed the legislature in 2021 and was vetoed, and a second attempt died in 2024, so no state credential currently exists to plan around. Protection comes from the national credentials instead: the RDN and NDTR titles through the Commission on Dietetic Registration, and the CNS through the Board for Certification of Nutrition Specialists.
In practical terms, the absence of licensure widens what a CNS graduate can do in Arizona compared with states that reserve medical nutrition therapy for licensed dietitians. It also means employers, not the state, decide which credential they will accept, so check job postings in the setting you want before committing to a route.
Before You Apply
Three things on this page are worth confirming directly with the school. GCU’s accreditation page and program page disagree on whether its master’s is accredited or in candidate status. Maricopa has not yet posted a 2026 to 2027 tuition table, so community college figures use the 2025 to 2026 schedule, and Sonoran’s clinical hour count differs between its catalog and its marketing.
