If you guess that it's the Chicago Public School kids who did the best, you'd mostly right. Crain's reports that 17% of the students who were accepted into the 8 Selective Enrollment High Schools last year attended private schools rather than CPS Elementary Schools. Needless to say, this is creating more than some tension for "CPS Lifer" parents who'd like some leg up for loyalty (and might fuel a few residency investigations).
