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

How to Become a Registered Dietitian in Maine

Maine licenses dietitians under the Maine Dietetic Practices Act, administered by the Office of Professional and Occupational Regulation (OPOR). Before practicing dietetics or using the protected title "Licensed Dietitian" (LD) in Maine, practitioners must hold both an active CDR registration and a Maine state license. Maine's healthcare landscape is shaped by MaineHealth — the state's largest health system — and Northern Light Health, along with a growing network of telehealth nutrition counseling services bridging the state's significant rural population to registered dietitians.

Step 1: Complete an ACEND-Accredited Nutrition Program

CDR's master's-degree requirement effective January 1, 2024 applies to all new RD/RDN candidates entering the profession, including those planning to practice in Maine. Your educational pathway must be ACEND-accredited:

• DPD + Dietetic Internship: ACEND-accredited didactic program followed by 1,200+ supervised practice hours with graduate credit or a concurrent master's degree. Maine does not host a large number of ACEND programs, so many Maine candidates complete their degrees out of state.
• Coordinated Program (CP): Integrates coursework and supervised practice within a single master's-level program. The University of New England (UNE) in Biddeford and the University of Maine offer nutrition science programs relevant to this pathway.
• MS/DI Combined Programs: Combined graduate degree and internship programs available nationally, often preferred by career changers and those outside New England ACEND programs.

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

Step 2: Pass the CDR Registration Examination

Maine requires active CDR registration before issuing a state license. Exam details:

• Format: 145 questions (125 scored + 20 unscored), computer-adaptive
• Delivery: Pearson VUE centers (Portland, Bangor, Auburn) or remote proctoring — remote proctoring is especially important for candidates in rural Maine
• 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; 1 PDU required in ethics

Remote proctoring through Pearson VUE is particularly valuable for candidates in rural Maine, eliminating the need to travel to an urban test center.

Step 3: Apply for Your Maine Dietitian License

After earning CDR registration, apply for a Maine LD license through OPOR:

• Application portal: Maine OPOR (maine.gov/pfr/professionallicensing)
• Required documents: CDR registration certificate, official transcripts, supervised practice verification, and application fee payment
• License fee: Approximately $50–$75 (verify current fee on the OPOR website)
• Endorsement: Out-of-state dietitians with equivalent active licensure may apply by endorsement
• Processing time: Typically 4–8 weeks for complete applications
• Renewal: Biennial; CE verification required at renewal

Maine does not currently participate in a multistate dietitian licensure compact. Practitioners providing telehealth nutrition counseling to patients in other states must verify licensure requirements for each patient's home state.

Continuing Education Requirements

Maine CE requirements at license renewal align with CDR's recertification standard:

• CDR requirement: 75 PDUs per 5-year cycle
• Maine state requirement: CE hours required at biennial renewal — verify the current requirement on the OPOR website, as Maine's legislature may update CE mandates
• Approved CE: AND-sponsored programs, CPEU-approved webinars, university courses, professional conferences, and preceptorship
• Maine's rural geography makes online CE particularly practical; CDR's Activity Log tracks PDUs earned through virtual formats
• Retain CE documentation for at least 5 years for potential audit

CE focused on telehealth nutrition delivery, rural food access, and chronic disease management is especially relevant for Maine practitioners working in underserved northern and eastern counties.

RD vs. RDN: What's the Difference?

"Registered Dietitian" (RD) and "Registered Dietitian Nutritionist" (RDN) are identical CDR credentials under two optional titles. CDR added "RDN" in 2013 to better reflect the breadth of the profession. In Maine:

• Maine licenses practitioners as "Licensed Dietitian" (LD) under state law
• Both RD and RDN holders qualify for Maine LD licensure equally
• Medicare, MaineHealth, and Northern Light Health credentialing bodies recognize both titles

Clinical RDs in Maine's hospital systems predominantly use "RD"; community nutrition and telehealth wellness roles more commonly use "RDN."

Maine RD Salary Ranges

Maine salaries for dietitians are influenced by the state's smaller population base and healthcare system scale, though Portland's growth has driven compensation upward:

• Entry-level clinical RD (Portland/Scarborough): $50,000–$62,000
• Experienced clinical RD: $62,000–$76,000
• Renal/dialysis RD: $65,000–$85,000
• Travel RD: $35–$50/hr (housing stipend and M&IE separate; rural Maine assignments often carry higher stipends)
• Rural Maine / Northern Light (Bangor, Presque Isle): $46,000–$62,000; travel assignments more common
• WIC/public health: $44,000–$58,000 on state pay scales
• Telehealth private practice: $55,000–$80,000+ depending on caseload and specialty

Maine's shortage of RDs in rural areas, particularly north of Bangor, drives demand for travel dietitians and telehealth nutrition counselors at rates that can significantly exceed local staff positions.
