It’s rare to find an educational intervention with as unambiguous a research track record as online charter schools. Now, to be clear, it’s not a large body of research by any stretch, its conclusions may change in time, and the online charter sub-sector remains relatively small and concentrated in a few states. For now, though, the results seem incredibly bad (Zimmer et al. 2009; Woodworth et al. 2015). In virtually every state where these schools have been studied, across virtually all student subgroups, and in both reading and math, the estimated impact of online charter schools on student testing performance is negative and large in magnitude.
Predictably, and not without justification, those who oppose charter schools in general are particularly vehement when it comes to online charter schools – they should, according to many of these folks, be closed down, even outlawed. Charter school supporters, on the other hand, tend to acknowledge the negative results (to their credit) but make less drastic suggestions, such as greater oversight, including selective closure, and stricter authorizing practices.
Regardless of your opinion on what to do about online charter schools’ poor (test-based) results, they are truly an interesting phenomenon for a few reasons.
