How to Become a Registered Dietitian in Iowa 2026: License Guide

How to Become a Registered Dietitian in Iowa

Iowa licenses dietitians through the Iowa Department of Public Health (IDPH) under the Iowa Dietetics Practice Act. Before providing dietetic services or using the protected title "Licensed Dietitian" (LD) in Iowa, you must hold both an active CDR registration and a state-issued license. Iowa's healthcare market — led by UnityPoint Health, University of Iowa Health Care, and MercyOne — provides robust employment opportunities in clinical nutrition, community health, and dialysis care.

Step 1: Complete an ACEND-Accredited Nutrition Program

CDR's master's degree mandate, effective January 1, 2024, requires all new RD/RDN candidates to graduate from an ACEND-accredited program at the graduate level. Your pathway options:

• DPD + Dietetic Internship: Complete an ACEND-accredited DPD, then a supervised practice internship of 1,200+ hours with graduate credit or a concurrent master's.
• Coordinated Program (CP): ACEND-accredited MS-level program that integrates didactic coursework and supervised practice — Iowa State University and the University of Iowa offer CP or combined-track programs.
• MS/DI Combined Programs: Designed to deliver the graduate degree and supervised hours in approximately two years; often the fastest route for post-baccalaureate candidates.

Core curriculum includes medical nutrition therapy, food science, community nutrition, foodservice management, biochemistry, and research methods. Verify ACEND accreditation status before enrolling at eatright.org/acend.

Step 2: Pass the CDR Registration Examination

CDR registration precedes Iowa state licensure. Exam details:

• Format: 145 questions (125 scored + 20 unscored), computer-adaptive
• Delivery: Pearson VUE centers (Des Moines, Cedar Rapids, Iowa City) or remote proctoring
• Fee: ~$200 (verify at eatrightpro.org)
• Domains: Principles of Dietetics, Nutrition Care for Individuals and Groups, Management of Food and Nutrition Programs, Population and Community Nutrition
• Maintenance: 75 PDUs per 5-year CDR recertification cycle

University of Iowa and Iowa State nutrition programs provide exam prep support to graduating students; AND's CDR exam study guide is the primary resource most candidates use.

Step 3: Apply for Your Iowa Dietitian License

After earning CDR registration, apply for licensure through IDPH's Professional Licensure Bureau:

• Application portal: Iowa Department of Public Health Professional Licensure (idph.iowa.gov)
• Required documents: CDR registration certificate, official transcripts, supervised practice verification, and application fee
• License fee: Approximately $50–$75 (verify current fee at idph.iowa.gov)
• Endorsement: Out-of-state dietitians with active equivalent licensure may apply by endorsement
• Processing time: Typically 4–8 weeks for complete applications
• License renewal: Biennial; CE verification required at renewal

Iowa does not participate in a multistate dietitian licensure compact as of 2026.

Continuing Education Requirements

Iowa's CE requirements mirror CDR's national standard:

• CDR requirement: 75 PDUs per 5-year recertification cycle (1 PDU in ethics required)
• Iowa state requirement: CE hours required for biennial license renewal — confirm current hour requirements on the IDPH website, as the legislature periodically updates continuing education mandates
• Approved providers include AND, CPEU-approved webinars, university coursework, professional conferences, and preceptorship hours
• Retain CE documentation for 5+ years in case of audit

Iowa has a strong community nutrition infrastructure through WIC and extension services; continuing education in public health nutrition and food insecurity programming is especially relevant in rural Iowa markets.

RD vs. RDN: What's the Difference?

"Registered Dietitian" (RD) and "Registered Dietitian Nutritionist" (RDN) represent the same CDR credential under two name options introduced when CDR expanded the title in 2013:

• Identical education requirements, examination, and 75-PDU maintenance cycle
• Identical recognition by Medicare/Medicaid, Joint Commission, and commercial payers
• Iowa licenses practitioners as "Licensed Dietitian" (LD) regardless of whether you use RD or RDN

Both designations are fully accepted across Iowa's healthcare system. Clinical environments and long-term care facilities tend to see "RD" usage most frequently; community and WIC settings often see "RDN."

Iowa RD Salary Ranges

Iowa's cost of living is moderate, and dietitian salaries reflect a balance between clinical demand and regional pay scales:

• Entry-level clinical RD (Des Moines/Iowa City): $50,000–$62,000
• Experienced clinical RD: $62,000–$76,000
• Renal/dialysis RD (DaVita/Fresenius): $65,000–$85,000
• Travel RD: $35–$50/hr (13-week contracts, stipends separate)
• WIC/public health RD: $45,000–$60,000 on public pay scales
• Rural Iowa: $46,000–$62,000 (critical access hospitals and SNFs)

University of Iowa Health Care and UnityPoint's large hospital campuses in Des Moines pay toward the higher end of the Iowa range; rural critical access hospitals increasingly use travel RDs to fill gaps.
