Idaho Dietitian License Requirements (2026)
Compiled and verified against primary state-board, CDR, and ACEND sources by DietitianLicense — cite-or-deny, with no invented figures. How we source & verify →
Idaho licenses dietitians under Idaho Code Title 54, Chapter 35, administered by the Idaho State Board of Medicine through the Division of Occupational and Professional Licenses (DOPL). Idaho's substantive standard is unusually streamlined: an applicant qualifies by holding current registration as a Registered Dietitian (RD) or Registered Dietitian Nutritionist (RDN) with the Commission on Dietetic Registration (CDR), and license renewal itself depends on continuing to maintain that CDR registration. The title "nutritionist" is not separately regulated — the statute expressly permits anyone to use "nutrition" or "diet" as a descriptive term.
Idaho Dietitian License Requirements
| Licensing Authority | Idaho State Board of Medicine (Dietetic Licensure), administered by the Division of Occupational and Professional Licenses (DOPL) |
| Protected Title | Licensed Dietitian (LD) |
| Education | Training in the science of nutrition and dietetics meeting current minimum academic requirements, via completion of didactic education and supervised-practice experience through an ACEND-accredited program (or a board-approved program with substantially equivalent requirements). |
| Exam | CDR Registration Examination for Dietitians (Commission on Dietetic Registration (CDR)) |
| Continuing Education | Not required |
| Endorsement (CDR/RD holders) | Because Idaho's licensure standard is itself simply holding current CDR registration (Idaho Code §54-3506), any RD/RDN with active CDR registration — regardless of which state they currently practice in — qualifies for an Idaho license under the standard application; there is no separate Idaho jurisprudence exam or additional state-specific testing layered on top of CDR registration. |

Idaho Code §54-3503 makes it unlawful to use the title "dietitian," "licensed dietitian (LD)," or "registered dietitian (RD)" without an Idaho license, but explicitly states: "Nothing contained herein shall be construed to prohibit the use of the term 'nutrition' or 'diet' as a descriptive term." The statute does not separately regulate or restrict the title "nutritionist." It also allows nationally credentialed registered dietitians to use that title without an Idaho license as long as they are not professionally practicing dietetics in the state, and exempts other Title 54-licensed professionals providing diet-related services within their own scope of practice.
