Dietitian Certification

Washington State holds 4,242 active credentials of this type — 0.8% of every active health care credential in the state. Here is what that number is made of, and how to check one.

What kind of credential this is

A Dietitian Certification is a Certification — a credential the state grants against a defined standard. It is what Washington uses where the work is real and regulated but typically carried out under someone else’s direction rather than independently.

That word is not a formality. Washington issues 145,796 active credentials in this form across the state, and it decides what the holder may do without someone else’s supervision. How a certification differs from the others.

When these credentials expire

Washington renews on the holder’s birthday, so these 4,242 expiry dates are spread right across the calendar rather than falling together. By year:

How long these holders have been credentialled

The oldest Dietitian Certification credential still active in Washington was first issued in 1989. 2,042 of the 4,242 were issued in 2024 or later — 48.1% of the profession is that new.

The disciplinary flag

None of the 4,242 active credentials of this type carries a disciplinary flag in the Department’s published file.

Do not let the date pass

4,242 credentials of this type are active in Washington. Washington renews most of them on the holder’s birthday, every year or every two years, and continuing-education hours have to be done before that date — not after. Leave your details and we will tell you when yours is close, and pass your request for continuing-education hours to providers who teach for this credential.
