As discussed in a previous post, there is a fairly well-developed body of evidence showing that charter and regular public schools vary widely in their impacts on achievement growth. This research finds that, on the whole, there is usually not much of a difference between them, and when there are differences, they tend to be very modest. In other words, there is nothing about “charterness” that leads to strong results. It is, however, the exceptions that are often most instructive to policy. By taking a look at the handful of schools that are successful, we might finally start moving past the “horse race” incarnation of the charter debate, and start figuring out which specific policies and conditions are associated with success, at least in terms of test score improvement (which is the focus of this post). Unfortunately, this question is also extremely difficult to answer – policies and conditions are not randomly assigned to schools, and it’s very tough to disentangle all the factors (many unmeasurable) that might affect achievement. But the available evidence at this point is sufficient to start draw a few highly tentative conclusions about “what works.” (more...)
