any good homeschool options for advanced students in WA state?

There's no way my kid is going back to regular school this Fall. In WA there are a couple options such as K12 & Connections Academy. Have any of you had dealings or insight into these options or have any other suggestions? My kid is supposed to start high school this year but is already 2 grades ahead in math & 1 in science & English. I don't want him to go to one of those schools that tries to hold him back. If he can graduate 2 years early then I want him to be able to.

Are any of you in the same situation? What are you doing this year?
