Superb thread with loads of information. I am moving to Chicago in August and have kids going to 2nd and 5th class. So will be keenly following this thread for information on schools. Planning to stay in Naperville and currently looking out for schools and apartments. Suggestions welcome. Also would like to know how the school ratings work there? Is it ok to enroll kids to a school with rating '8' or it should be 9 or 10? What are the differences with change in ratings? And do schools offer extra activities(within/after school hours) How to find out about it? School websites donot list that out.
