When Does a Washington MAST Permit Expire?

Washington Class 12 and Class 13 permits are valid for five years from issue. You must renew through a provider certified by the Washington State Liquor and Cannabis Board (LCB) before expiration to keep serving legally.

How Renewal Works

  1. Confirm your permit class (Class 13 for servers 18–20; Class 12 for mixologists 21+).
  2. Complete a MAST course from an LCB-certified provider.
  3. Carry your new permit; employers must keep copies on file.

Where Does Our Course Fit?

Certification Experts offers an educational alcohol-service course covering Washington topics — ID checks, intoxication signs, liability. It is useful preparation and professional development, but it is not LCB-certified MAST training and does not by itself issue or renew a MAST permit. For the official permit, use an LCB-certified provider listed at lcb.wa.gov.

Quick Answer: Washington requires anyone who serves or sells alcohol to hold a MAST permit, issued through a trainer licensed by the Washington State Liquor and Cannabis Board (WSLCB). Certification Experts is not a WSLCB-licensed MAST provider, so your MAST permit must be obtained from a WSLCB-approved Washington trainer.
