The folks at the right-leaning Washington DC think tank Fordham Foundation have put out a new report comparing charter schools in five different cities.
At first, it seems like the usual charter school advocacy: "For Chicago, Cleveland, Denver, and Indianapolis, the charter school sector performs, on average, at one-third to two-thirds of a standard deviation above the district average. Of these five cities, Albany’s charter sector led, performing over one standard deviation above Albany’s district schools."
But the report notes the not every city's charter schools outperform the comparable district schools (much less statewide averages) and specifically recommends closing down ineffective charters at a steady clip.
The report identifies as Chicago's lowest performing charters as Catalyst Circle Rock, Catalyst, Galapagos, Kipp Ascend -- as well as some top performing ones such as LEARN, Locke, Namaste.
