How to Become a Registered Dietitian in Tennessee (2026 Guide)

How to Become a Registered Dietitian in Tennessee

Tennessee's healthcare landscape is dominated by a powerful Nashville-centric hospital market — home to Vanderbilt University Medical Center, HCA Healthcare's corporate headquarters, and Ascension Saint Thomas — alongside one of the nation's most active HCA hospital networks and an extensive DaVita dialysis footprint. The state requires both national CDR registration and a Tennessee state license before you may practice under the protected "Licensed Dietitian" title.

Here is the complete 2026 guide to Tennessee RD licensure.

Step 1: ACEND-Accredited Nutrition Program

Effective January 1, 2024, the CDR requires all new RD candidates to hold a minimum master's degree from an ACEND-accredited program. This is a national requirement that applies in Tennessee. ACEND graduate programs incorporate the required supervised practice hours (at least 1,000 hours), allowing students to satisfy both the academic and experiential CDR eligibility requirements through a single program pathway.

Tennessee has ACEND-accredited graduate programs at Tennessee State University, Lipscomb University, and other institutions. Graduates of any ACEND-accredited program nationwide are eligible to apply for Tennessee state licensure.

Step 2: CDR Registration Examination

After completing your ACEND-accredited graduate program, you must pass the CDR Registration Examination for Dietitians:

• Fee: approximately $200
• Format: 145 questions (125 scored + 20 unscored pretest), computer-adaptive
• Domains: principles of dietetics; nutrition care for individuals and groups; management of food and nutrition programs; food science and nutrient composition
• Maintenance: 75 PDUs per five-year cycle to maintain active CDR registration

Tennessee's licensure application requires proof of active CDR registration — you must pass the CDR exam before the state Board will issue a Tennessee license.

Step 3: State Dietitian License

The Tennessee Division of Health Related Boards (under the Tennessee Department of Health) licenses dietitians under the Tennessee Dietitian/Nutritionist Licensing Act. Application steps include:

1. Complete the Tennessee Division of Health Related Boards dietitian licensure application.
2. Provide proof of current, active CDR registration (RD or RDN credential).
3. Submit official transcripts from your ACEND-accredited graduate program.
4. Pay the state licensure fee (approximately $75–$100; verify the exact current fee with the Division before submitting your application).
5. Complete any required background check or attestations as specified by the Division.

Tennessee dietitian licenses are renewed on a set biennial or biannual cycle. Confirm the current renewal schedule and any updated CE or documentation requirements directly with the Tennessee Division of Health Related Boards.

Continuing Education

Tennessee requires continuing education for dietitian license renewal, structured around CDR's 75 PDU / five-year framework. Approved CE activities include professional conferences, webinars, self-study modules, supervised practice, and peer-reviewed research. Tennessee's Nashville health corridor offers abundant CE opportunities through hospital grand rounds, professional society events, and clinical nutrition networks. Confirm current state-specific CE hour requirements and any Tennessee-specific mandatory topics with the Division of Health Related Boards, as requirements may be updated between renewal cycles.

RD vs. RDN

The Registered Dietitian (RD) and Registered Dietitian Nutritionist (RDN) credentials are legally equivalent and interchangeable under CDR policy. Tennessee's Division of Health Related Boards and all major Tennessee health systems — including Vanderbilt, HCA, and Ascension — recognize both titles equally. Neither designation confers any additional scope of practice in Tennessee over the other. The choice between RD and RDN is a matter of personal professional preference, with no impact on licensure requirements or employer eligibility.

Tennessee RD Salary Ranges

Tennessee RD salaries reflect the Southeast regional market with a Nashville premium driven by the concentration of major health systems:

• Entry-level (0–2 years): approximately $52,000–$58,000 per year
• Mid-career (3–7 years): approximately $58,000–$67,000 per year
• Experienced (8+ years) or specialty: approximately $67,000–$76,000 per year
• Renal/dialysis premium: DaVita operates extensively throughout Tennessee; renal RDs typically earn a $4,000–$8,000 annual premium over general clinical rates
• Travel RD contracts: travel assignments in Tennessee — particularly for rural communities in Appalachian East Tennessee and West Tennessee — typically pay $35–$50 per hour with housing and travel stipends
