This report infers the causal impact of attending a charter school on student performance and finds that whether charters outperform traditional public schools depends on the location, grade, and subject.
This paper analyzes existing charter outcome studies and finds that there is great variety in charter school performance, with charters outperforming in some grade spans/subjects and underperforming in others.
This paper provides an analysis of 14 charter school studies that use the two most rigorous methods: either randomization based on lotteries, or value-added modeling.
