A recent American Enterprise Institute study dispels myths about charter schools by comparing them to nearby district schools in a few novel ways.
Author Nat Malkus gathered data on school type, locale, enrollment, proficiency, discipline rates, demographics, and the number of English language learners and special education students they serve. Sources included the National Center for Education Statistics, the Department of Education’s Office of Civil Rights, and EDfacts.

Through the study’s various lenses—school discipline, student enrollment, achievement, or something else—charter schools are repeatedly shown to differ more from one another than district schools do. (There is also more variance between charters than between charter schools and their...
