Abstract: The Mayor of Indianapolis' latest annual charter school accountability report shows that charter schools in the city are improving more rapidly than district schools and some schools are improving far more rapidly than other schools in the state. The city's mayor is currently the only mayor in the nation with authority to grant charters for schools, and his annual report card on them has been widely praised for its level of detail and scrutiny. The report found, however, that most of the charters struggle to adequately handle administrative requirements, such as turning in state reports on time, keeping documentation and running board meetings properly. The report contains test scores, attendance data, state audit information and other results from the 12 Indianapolis charter schools that have been operating for at least two years.
