MANY CHARTER SCHOOLS ARE FAILING UNDER NCLB Florida is home to more than 300 charter schools -- public schools funded by your tax dollars but run by groups, such as cities, nonprofits or management companies. Some operators are steeped in education experience, while others have no academic credentials. Many charter schools enjoy good reputations. But scores of them continue getting education dollars despite records of low student achievement and financial mismanagement. A yearlong investigation by the Orlando Sentinel found that the state's lack of oversight has allowed students to fail academically and charter operators to profit from their relationships with the schools. This four-part series looks at student performance, charter-school spending and what the state is doing -- or not doing -- to hold the campuses accountable.
