This report, along with the companion spreadsheet, provides the first comprehensive description ever compiled of charter school discipline. In 2011-12, every one of the nation’s 95,000 public schools was required to report its school discipline data, including charter schools. This analysis, which includes more than 5,250 charter schools, focuses on out-of-school suspension rates at the elementary and secondary levels. The report describes the extent to which suspensions meted out by charter schools for each major racial group and for students with disabilities are excessive or disparate.
