School lasts 6.5 hours/day, and that includes art, recess, and lunch. Pick a school where people aren't being horrible - the teachers look happy, the principal is energetic, and kids aren't beating on one another. Your kids will be *fine*, because a highly rated school mostly measures the family income of the kids who attend that school.
I say that as a teacher, and as a mom who sent her kids to not so "great" public schools. They were fine, academically, and my kids learned lessons that you can't buy.
