Charter schools aren't turnarounds

In light of last night's WEC event elevating charters as a great multi-applicable education answer, this post on (the generally rah-rah charters) The Quick and The Ed, is telling. Even when given an open door, charter schools aren't interested in being turnaround schools.
The response tells you why: you can't pick and choose your students in a turnaround school, and you can't counsel them out.
