Three decades after the first charter school law passed in the United States, myths about these public schools not only persist but continue to fuel strong claims and divisive debates. Commentators point to education management organizations (EMOs), for-profit organizations which manage or operate a network of charter schools, as examples of private entities supposedly profiting off public education. In this report, the authors dispel three common myths about charter schools and their funding, spending, and management. They draw upon comprehensive school funding data collected from traditional public schools (TPS) and public charter schools in 18 cities during fiscal year (FY) 2018.
