The data on students in charter schools is mixed. Most schools do about the same or worse than the public schools they supplement or detract from. While the data strongly suggest that there is not even a wisp of a panacea here for poor schools in city districts, I’m unaware of any data at all that says these schools should be used in rich high performing school districts. When a charter school moves into that area, it would seem to be evidence of what many have claimed all along, that this is more of a privatization movement than any attempt to help students, a way of converting a public good into a private profit.
