"The Charter Difference"

This Sun-Times story cites a recently completed study stating that charter school students actually gained less in their ACT achievement scores than students from neighborhood schools. Perhaps most interesting, is the bigger picture:

"Last year, Chicago charter high school kids produced an average ACT score of 16.71 versus 15.82 in neighborhood high schools... However, the neighborhood kids showed far better ACT gains over three years."

So, in other words, the charter schools have drawn higher achieveing students, but haven't done much with them once they got there.
