I just went to www.greatschools.com. I am ecstatic. The kids at CPS - Disney Magnet on Marine drive nailed the ISATs. They out did the suburbs. Don't believe me, then go to this link. Compare and contrast. There is no need for private schools in Chicago, when CPS has options. Albeit, if your kid cannot get into Disney, then consider selective enrollment.
Also, for those who feel that they must move north; consider Rogers Park, when it makes economic and educational sense. All I can say is the proof is in the pudding. All the rest is commentary. The test scores at this point don't lie.
