Charter schools in Chicago have been around for nearly two decades and while they continue to expand, some people are still strongly opposed to the education model. Chicago Public Schools is holding public hearings Wednesday night about charter schools. Seven charters want to open a dozen new campuses across the city, including the Noble Network, which wants to build its 17th high school on the Southwest Side. Of all the proposals, it’s this one from the Noble Network of Charters that has stirred up the most controversy. Why is that and what does this mean moving forward? WBEZ Education Reporter Linda Lutton helps us sift through those questions. (Flickr/Flickr Lucy Gray)
