Here’s a great series of ProPublica stories on the accountability of “Alternative Schools”, charter schools and the like, across the nation.

Stories examine how districts can shunt underperforming students or even dropouts to charter schools. How for-profit schools get money for the state, even for kids who’ve dropped out. As a result of a story that ran in this series, Florida initiated a deeper investigation into whether charter schools are underreporting the number of dropouts.
