(NBC Chicago) — The Chicago Public School system is spending approximately twice as much to educate students in the Cook County Jail as opposed to students in traditional schools. According to figures released by CPS, $7.5 million was budgeted to educate roughly 300 student-inmates at Consuella B. York Alternative school, housed within the confines of the jail. In some respects it’s like any other Chicago public high school. To enter, one must have an ID and walk through a metal detector. But once inside, the student body is captive and the teachers committed.
