How do I get a class 12 or 13 permit in Washington if I was trained in another state?
(1) If a person completes an alcohol server training course in another state and that training course is also certified in the state of Washington, he or she may receive a class 12 or 13 permit in Washington by completing the provider's board-certified Washington state supplement to the program and passing the standardized exam.
(2) A trainer or provider shall issue a class 12 or 13 permit, which will expire five years from the first day of the month following the date an original training course was taken. For example, if you complete a training course on June 15, 2010, your class 12 or 13 permit will expire on July 1, 2015.
