Massachusetts Dietitian Licensing

Massachusetts licenses dietitians as Licensed Dietitian/Nutritionists, or LDNs, under General Laws chapter 112, sections 201 to 210. The Board of Registration of Dietitians and Nutritionists issues the license, and the statute treats "licensed dietitian" and "licensed nutritionist" as interchangeable terms for the same credential.

The way the law is written matters for out-of-state RDNs deciding whether they need it.

What does the Massachusetts license control?

The statute centers on the title. Section 206 says, "No person shall hold himself out to be a licensed dietitian/nutritionist unless so licensed." It then says the section "shall not restrict any person who does not hold himself out to be a licensed dietitian/nutritionist" from a list of activities, including furnishing information about food, food products or dietary supplements, practicing another health profession they are authorized to practice, and practicing a health profession that "includes a dietetic or nutritional practice component."

The penalty section follows the same pattern. Section 209 makes it a misdemeanor for "any person acting or purporting to act as a licensed dietitian/nutritionist without first obtaining a license," and bars anyone from suing in Massachusetts courts for payment for services rendered "as a licensed dietitian/nutritionist" without a valid license at the time.

So the Massachusetts license is about practicing as an LDN, and an RDN who serves Massachusetts clients without the license has to stay clear of presenting as a Massachusetts licensed dietitian/nutritionist. Employers, payers and platforms may still require the license. Read sections 206 and 209 in full before deciding you do not need it. Our post on title protection, certification and licensure explains the categories.

Who qualifies for a Massachusetts LDN?

Section 203 and the Board's rule at 268 CMR 3.01 require a sworn application showing that you:

• are at least 18 and of good moral character;
• hold a bachelor's degree or higher with a major in dietetics and nutrition, human nutrition, nutrition education or public health nutrition, or a degree with enough nutrition coursework, which the rule spells out in semester hours of biological sciences, chemistry, behavioral sciences and foods and nutrition;
• completed a board-approved post-baccalaureate internship of at least 900 hours supervised by a licensed dietitian/nutritionist, or comparable paid professional experience, such as three years after a bachelor's, two after a master's or one after a doctorate; and
• passed a competency exam the Board approves.

Applications are "signed under the penalties of perjury" (268 CMR 3.01(1)(b)). After passing the exam, an applicant has two years to apply for the license; waiting longer can mean re-examination at the applicant's expense (section 204).

Is there a route for dietitians credentialed in other states?

Yes. Section 208 lets the Board "provide reciprocal recognition for registered, certified or licensed dietitians/nutritionists from other jurisdictions." The Board's rule puts it into practice: it may issue a license "without examination and by reciprocal recognition" to anyone holding a license, certification or registration as a dietitian/nutritionist issued by another state or jurisdiction, if:

1. the other credential's requirements are substantially equivalent to or exceed Massachusetts's, as the Board determines; and
2. the applicant's credential there has not been revoked, suspended or otherwise encumbered through formal discipline.

Our guide to license by endorsement compares this with other states.

What does it cost?

The fees are not in the statute or the Board's licensing rules. Both say fees are set by the Secretary of Administration and Finance under General Laws chapter 7, section 3B. The Board's rules add that there is "no provision for proration of fees" between renewal dates and that application and license fees are not refundable (268 CMR 3.05 and 3.07). Check the current schedule before you apply.

When does an LDN renew?

On your birthday, every two years. The original license runs at least 24 months and expires on the licensee's birthday after that period; each renewal falls on the second anniversary of that birthday (section 207 and 268 CMR 3.02). A February 29 birthday renews on March 1.

To renew, you submit the renewal application and fee at least 30 days before the license expires and certify, under the penalties of perjury, that you completed at least 30 hours of continuing education in the two years. The Board may audit. Late renewals carry a late fee set by the same finance schedule (268 CMR 3.06).

Licensees must also keep the Board informed of their principal business address, every other business address and their home address, and respond within 30 days to written communications from the Board (section 210 and 268 CMR 3.04).

Is Massachusetts in the Dietitian Compact?

No. Massachusetts has not enacted the compact, so a Massachusetts resident cannot use it and an out-of-state RDN cannot use it to practice in Massachusetts. No state issues compact privileges yet in any case. See which states have joined.
