Hi J.,
I agree with the others that Kentwood, Rockford, etc are top rated school districts in the area. However, Rockford is HUGE and I have heard complaints from my friends that live there about the size.
I moved to Sparta, just north of Grand Rapids, to have my children attend their schools 2 years ago. It is a small district that has a lot of programs that other schools have lost due to budgetary cuts. I have been so impressed with what my daughter has learned. Not only academically, but as far a values. Each month they touch on integrity, compassion, pride or etc. They are encouraged to be caring and to "get caught" doing something nice for others.
There are so many good districts in the area. Take your time to look around. I just happen to love Sparta.
