I'm another Ignatian! I guess I don't need to tell you how great St. Ignatius College Prep is. As for an elementary school... I'm a Chicago Public School teacher and I believe test scores don't give an accurate view into any school, public or private. You can only find out so much from test scores, they can't tell the whole story, and while one person may feel a school is the best thing since sliced bread, it may not be right for another. The best way to see if a school is a good fit for your child is to walk into it with your child, talk to the adults in the building, and go with your instinct. I know it is difficult, but it all falls in place in the end. Good Luck!
