I moved here last year.
Both my boys are in Eagle schools. One is in preschool and the other is Elementary. We have friends with kids in all the local Eagle schools and everyone is happy with thier choices. Kids, I've talked too seem to like Eagle Middle and Eagle High ... in addition, to the public their are several charter and private schools in the area.
Everyone talks about the commute and traffic being bad, but it depends on where you come from. Coming from Los Angeles and then Phoenix ... I think traffic here is a cake walk. We are only 9 miles or so to downtown Boise ... very close to shopping in Merdian. My husband work near the Mall area and his commute is 20 mins max. Now if you come from Kanab, Utah or another small town you might find traffic to be very bad ... some areas can get bogged down ... again, it simply depends on what you are used to.
Bottom line, we love it here

Side note: One friend did not like the teachiing quality at the Eagle public schools - but she is a highly educated teacher herself - so, she pulled her son out of 2nd grade and sent him to the Hidden Hills Charter School (about 3 miles from Eagle) and she loves it. There is another Charter (North Star) in Eagle that also uses the Harbor Method of Education.
Some people love it, others don't. I suggest visiting the education websites 4theluvofBoise suggested and then visiting the schools when you come here. That's what we did and that is how we chose our schools.
