Cal Poly markets its dietetics pathway as the “Dietetic Internship & Master’s Degree Combined Program,” but the school actually awards two separate credentials rather than one bundled degree: a Dietetic Internship verification statement, plus a master’s that can be Cal Poly’s own or one already held from elsewhere. Applicants who assume this is a single combined degree, the way Fresno State’s or Sacramento State’s programs work, should read the structure carefully before applying.

Bachelor of Science, Nutrition (Applied Nutrition Concentration)

The estimated tuition for the B.S. at Cal Poly SLO is approximately $14,000 to $15,000 per year in-state, once the CSU systemwide $6,838 tuition figure is combined with Cal Poly’s own campus-based fees, which run notably higher than most CSU campuses. The Applied Nutrition Concentration follows the standard four-year, 120-credit bachelor’s timeline.

B.S. Curriculum

The Applied Nutrition Concentration is Cal Poly’s ACEND-accredited DPD, currently accredited for an 8-year term running from January 2024 through June 30, 2032.

B.S. Admissions

Admission follows Cal Poly’s standard, selective undergraduate admission process; students declare the Applied Nutrition Concentration to be on the DPD track.

Dietetic Internship

The estimated cost for Cal Poly’s stand-alone Dietetic Internship is approximately $12,330 to $14,330 for the 2025-26 cycle, billed through Open University at $349 per unit for 21 units plus a program fee. The internship runs a minimum of 32 weeks and is not itself a degree.

DI Curriculum and Structure

Cal Poly offers two paths into the same accredited internship. In the cohort option, students already enrolled in or accepted to a Cal Poly graduate program, such as its own M.S. in Nutrition, complete the internship concurrently with their coursework. In the stand-alone option, applicants who have already completed a graduate degree elsewhere enroll in the internship on its own through Open University.

You Should Know

Even in the cohort option, Cal Poly awards two separate credentials on completion: a Dietetic Internship verification statement, once ACEND and Cal Poly requirements are met, and a master’s degree, either Cal Poly’s own or one brought from elsewhere. This is not one single combined-title degree the way some other CSU campuses structure their programs, despite Cal Poly’s own “Combined Program” branding.

DI Supervised Practice

  • Minimum 1,114 total hours over at least 32 weeks: 320 medical nutrition therapy, 192 foodservice management, 256 community nutrition, 128 extended core, 64 elective, 64 staff relief, 90 alternative
  • Rotations placed across San Luis Obispo, Santa Barbara, and Ventura counties
  • About 10 interns admitted a year

At 1,114 hours, Cal Poly’s total sits just above the roughly 1,000-hour ACEND standard, delivered through a small cohort with a defined regional footprint rather than a nationally dispersed placement pool.

DI Admissions

  • DPD verification statement (within 5 years) or a Declaration of Intent to Complete Degree and DPD
  • Either a completed master’s degree, or current enrollment or acceptance in a Cal Poly graduate program
  • GRE not required
  • December 20 deadline for the concurrent-cohort option; April 1 deadline applies to Cal Poly’s separate M.S. in Nutrition, for students pursuing that path first

Tuition

Cal Poly bills its stand-alone Dietetic Internship through Open University at $349 per unit; at 21 units, that is $7,330 in tuition before the internship’s separate program fee. The B.S. is billed at the CSU systemwide flat rate rather than per credit.

  • $6,838/year in-state CSU systemwide tuition for the B.S., before Cal Poly’s own campus fees
  • Cal Poly’s total resident tuition and fees for undergraduates run approximately $14,037 to $15,039 a year depending on college, notably higher than most other CSU campuses
  • $7,330 in Open University tuition for the stand-alone Dietetic Internship (21 units at $349/unit), plus a program fee of roughly $5,000 to $7,000 pending approval, for a total of about $12,330 to $14,330

Be aware that:

The stand-alone Dietetic Internship is not eligible for traditional federal financial aid, since it is billed through Open University rather than as a standard degree program. Its program fee is also described by Cal Poly as pending approval, so the final total could shift from the $12,330 to $14,330 range quoted here.

Cal Poly’s own campus fees push its total undergraduate cost well above the CSU systemwide $6,838 tuition figure and above most other CSU campuses profiled in this guide, so students comparing Cal Poly to a lower-fee CSU should use the all-in $14,000 to $15,000 range rather than the tuition-only figure.

Official cost figures are published on Cal Poly’s dietetic internship admissions page and Cal Poly’s estimated fees page.

Why Choose This Nutrition Program?

Best suited for students who understand upfront that this is two separate credentials rather than one combined degree, and who want a small, regionally placed internship on California’s Central Coast.

Students who already hold a master’s can apply to the stand-alone Dietetic Internship directly, without enrolling in any Cal Poly degree program, though they’ll pay out of pocket since Open University enrollment isn’t financial-aid eligible.

Cal Poly’s own graduate students, whether in the M.S. in Nutrition or another Cal Poly graduate program, can pursue the internship concurrently with their degree rather than adding it on afterward.

The honest trade-off is cost and structure: despite the “combined program” name, this isn’t one bundled credential, the stand-alone internship carries a real financial-aid gap, and Cal Poly’s own campus fees make both the B.S. and the internship pricier than equivalent CSU-system options elsewhere in this guide.

Accreditation

Cal Poly San Luis Obispo is institutionally accredited by the WASC Senior College and University Commission (WSCUC), which governs credit transfer, graduate admission eligibility, and federal financial aid access across the campus.

ACEND accredits Cal Poly’s Didactic Program in Dietetics, within the B.S.’s Applied Nutrition Concentration, through June 30, 2032, and separately accredits its Dietetic Internship. Cal Poly’s stand-alone M.S. in Nutrition, a thesis-based research degree, is not itself ACEND-accredited, which is normal for a research master’s rather than a deficiency.

Graduates who complete the Dietetic Internship together with a master’s degree, whether Cal Poly’s own or one held from elsewhere, are eligible for the Commission on Dietetic Registration’s national exam. Graduates of the DPD alone are not RD-eligible and must complete a Dietetic Internship, at Cal Poly or elsewhere, plus a graduate degree, to pursue the credential.
