Legislation this year opened the door to the establishment of more charter schools. This fall, 31 new charters opened. Unfortunately, six of the 31 new schools are managed by operators who didn't meet the state's average for low-income students, according to a report by Education Trust-Midwest. Mosaica, Leona Group, Edtec Central, Education Management and Networks, Solid Rock Management Company and Midwest Management Company manage schools that failed to meet the state's average 33rd percentile on the state's Top to Bottom rankings.
