The Washington State Liquor Cannabis Board requires us to provide a proof of completion as soon as the student completes the training course. We also have to mail the official MAST Permit to you by postal mail. Your proof of completion can be used to show you have completed the required training until you receive the official permit in the mail. At this time the state does not allow any digital or copies of the MAST Permit this is why we have to physically mail it to the student.
