Hopefully, someone can respond and give you information on the schools but in the mean time, if you want to know more about the schools on Whidbey, you can check out a website which might be helpful. It lists test scores and opinions from parents, which in my opinion, is more helpful than just looking at test scores. The web address is
GreatSchools.net. I think Coupeville and Oak Harbor are very different from one another. If I had a choice, I would choose Coupeville over Oak Harbor any day, but that's just my opinion. Good luck!
