I'm trying to understand what you're saying here. She has earned a high school diploma that is lawfully recognized by the state of Washington. Are you saying that in order to get this job (which appears to be a state regulated job) she should be required to go and get an additional document that carries the same weight that her diploma does under those laws? (By "same weight" I mean demonstrates that she has met all of the requirements set forth by the state for her primary education.) How would it be "best and easiest" to go through those additional steps and expenses when she has already lawfully met the requirements?
