Illinois Dietitian License: Hours, Exam, and Renewal

To work as a dietitian in Illinois, you need a license from the Illinois Department of Financial and Professional Regulation (IDFPR) under the Dietitian Nutritionist Practice Act. The Illinois dietitian license requires a qualifying degree, at least 900 hours of supervised practice, a passing score on the national Commission on Dietetic Registration (CDR) exam, and a $100 application fee.¹ Once issued, the license renews on a two-year cycle with 30 hours of continuing education.

Who Needs the License

The Act covers two activities: providing medical nutrition therapy, and holding yourself out to the public as a dietitian or nutritionist. If you do either for pay, you need the license.²

Several groups are exempt and do not need this specific license:

Physicians, advanced practice registered nurses, physician assistants, and other professionals licensed under a different Illinois act, when providing nutrition services inside their own scope.
Federal and state government employees providing medical nutrition therapy as part of their official duties.
Dietetics students and trainees working under supervision, as long as they don’t practice independently and use a title identifying them as students.
Health food store employees sharing general, nonmedical information about products they sell.
People employed by nonprofits, government agencies, or accredited schools, practicing nutrition as part of their job.

These exemptions are narrow. General nutrition tips in a retail setting are not the same as individualized disease management, and work that crosses into medical nutrition therapy almost always requires the license.

Education Requirements

Illinois statute requires at least a bachelor’s degree in human nutrition, dietetics, food systems management, clinical nutrition, or a closely related field from a regionally accredited institution.² If your degree title doesn’t match one of those fields exactly, your coursework still qualifies if it includes at least 18 semester hours of clinical or life sciences and 18 semester hours of nutrition or metabolism, with specific content in areas like anatomy, biochemistry, and counseling.¹

There is a practical catch. The Illinois statute still refers to a baccalaureate degree, but CDR began requiring a master’s degree for all new exam applicants on January 1, 2024.³ Because passing the CDR exam is a prerequisite for the Illinois license, anyone starting the process now effectively needs a graduate degree. Dietitians who were already registered with CDR before that date are not affected.

Supervised Practice: 900 Hours

You also need to complete at least 900 hours of supervised practice in dietetics or nutrition within a five-year window.¹ The hours happen in settings like hospitals, community health programs, and food service operations, under the direction of a registered dietitian, a licensed dietitian nutritionist, or another qualified supervisor. Most candidates meet this requirement through an ACEND-accredited dietetic internship, and many internships run longer than the minimum.

Passing the CDR Exam

Once your education and supervised practice are done, you have to pass the national registration examination given by CDR. Illinois accepts this as its qualifying exam, so there is no separate state test.² You pay the exam fee directly to CDR or the testing service, separate from the state application fee.

Applying to IDFPR

After you pass the exam, you apply through IDFPR’s online CORE system and submit proof of your degree, your supervised practice, and your exam results. The application fee is $100.¹

If you already hold a dietetics license in another state, you can practice in Illinois for up to six months while your Illinois application is pending, as long as you’ve submitted a written application to IDFPR.²

Renewing Your License

Illinois dietitian nutritionist licenses renew on a two-year cycle ending October 31 of each odd-numbered year.⁴ The renewal fee is $50 per year, which comes to $100 for the two-year period.¹

Every renewal period you need 30 hours of continuing education relevant to dietetics and nutrition practice.⁴ IDFPR approves sponsors who offer qualifying coursework.

What the License Lets You Do, and What It Doesn’t

A licensed dietitian nutritionist in Illinois provides medical nutrition therapy, which covers interpreting clinical data, developing nutrition care plans, counseling on food and drug interactions, managing food service in healthcare settings, and overseeing medical weight control programs. The license also allows ordering nutrition-related lab tests and recommending therapeutic diets. One important boundary: the Act explicitly excludes medical diagnosis from the scope.²

The license also controls who may use certain titles. Only a licensee may use “dietitian nutritionist,” “dietitian,” “nutritionist,” “nutrition counselor,” or the abbreviation “L.D.N.” with their name. Using one of those titles without the license is a separate violation from providing unlicensed therapy.

If Your License Lapses

A lapsed or inactive license is different from a revoked one, but it still has to be restored before you can practice. You submit proof of fitness along with a $20 restoration fee plus any lapsed renewal fees, capped at $300 total.¹ Proof of fitness can include evidence that you kept practicing lawfully in another state during the lapse. If you weren’t, IDFPR evaluates your current competence through a process set out in its rules, and you also have to meet the continuing education requirement and pay the current renewal fee.²

Military service members who let a license lapse during active duty can restore it without paying lapsed renewal fees, as long as they apply within two years of an honorable discharge.

If a license was revoked rather than lapsed, restoration is possible only after any term of discipline is complete and the Secretary of the Department finds that restoration serves the public interest and that the applicant has been sufficiently rehabilitated.⁵

Penalties for Working Without the License

Practicing dietetics in Illinois without a license carries both civil and criminal exposure. IDFPR can impose a civil penalty of up to $10,000 per offense after a hearing, and that penalty order becomes enforceable the way a court judgment would be.⁶ Criminally, a first offense is a Class A misdemeanor and a second or later offense is a Class 4 felony.² The civil and criminal tracks run independently; the same conduct can trigger both.
