The U.S. Department of Education’s Office of the Inspector General issued a stinging audit, showing a near absence of oversight of charter school spending in the three states studied: Florida, Arizona, and California. On the same day, the California charter schools association celebrated another big expansion of the charter sector in that state. There are now more than 1,000 charter schools with nearly half a million students in them, and the state department of education lacks the staff to monitor them. Some of the schools never open; some open and close within a year or two. Some pay outrageous executive salaries.
