What kind of credential this is

A Medical Test Site Certificate of Waiver License 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 1,325 expiry dates are spread right across the calendar rather than falling together. By year:

The disciplinary flag

None of the 1,325 active credentials of this type carries a disciplinary flag in the Department’s published file.

Do not let the date pass

1,325 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.

We take no commission and we vouch for no training provider. We have no arrangement with any provider today — we are collecting these requests in order to go and find them. What we do with this.
