Charter schools, which have been criticized for grabbing billions in taxpayer dollars with promises to reinvent public education using corporate efficiencies and values, are finding themselves under fire from industry insiders who are saying that these hyped market-based reforms don’t work.

Last week when former President Bill Clinton meandered onto the topic of charter schools, he mentioned something about an “original bargain” that charters were, according to the reporter for The Huffington Post, “supposed to do a better job of educating students.”

A writer at Salon called the remark “stunning” because it brought to light the fact that the overwhelming majority of charter schools do no better than traditional public schools. Yet, as the Huffington reporter reminded us, charter schools are rarely shuttered for low academic performance.
