The Uncertain Future Of Charter School Proliferation

Matthew Di Carlo:

As discussed in prior posts, high-quality analyses of charter school effects show that there is wide variation in the test-based effects of these schools but that, overall, charter students do no better than their comparable regular public school counterparts. The existing evidence, though very tentative, suggests that the few schools achieving large gains tend to be well-funded, offer massive amounts of additional time, provide extensive tutoring services and maintain strict, often high-stakes discipline policies.

There will always be a few high-flying chains dispersed throughout the nation that get results, and we should learn from them. But there's also the issue of whether a bunch of charters schools with different operators using diverse approaches can expand within a single location and produce consistent results.

Charter supporters typically argue that state and local policies can be leveraged to "close the bad charters and replicate the good ones." Opponents, on the other hand, contend that successful charters can't expand beyond a certain point because they rely on selection bias of the best students into these schools (so-called "cream skimming"), as well as the exclusion of high-needs students.
