Charter schools' freedom to set and enforce their own discipline rules has raised concerns among educators, policymakers, and parents, who worry that strict policies may push students out of some schools for minor infractions. To examine those practices, Education Week analyzed national and district-level data on student expulsions and suspensions and tracked efforts in some urban districts to establish uniform disciplinary standards for charters and regular public schools. This infographic compares out-of-school suspension and expulsion rates in charter schools with traditional public schools.
