We love the Evanston schools. There are pros and cons to all - private included - but overall, we've had a great experience. And lots of my friends went to public school here and are well accomplished, many having gone to Ivy League schools. Test scores are really just an indication of diversity. The Evanston schools with higher test scores are those in North Evanston, which is wealthier and whiter. There's a pro and con to that situation as well. The curriculum is the same across the board and I hear good things about all schools and have friends with kids in all of them. The only school that people have some issues with is Oakton. For awhile there was a not so great principal and then a series of interim principals so it lacked direction. The population is more diverse than other schools and for some that was an issue in the classroom as well as with after school playdates, etc. On the other hand, I know people who love that school and their kids have thrived. It probably wouldn't be my first choice, but I'm not super informed about it. All other schools I would gladly send my kids to and personally would house hunt in any of their districts. Good luck! I think it's a great, diverse, interesting place to live.
