The vast majority of literature on school choice, and charter schools in particular, focus on attending an elementary or middle school and often focus on test scores or other proximal outcomes. Much less is known about the long-term effects of attending a charter high school. It is important to fill this information void for a few reasons. First, schools in general affect more than just students’ test scores. Second, high schools make up a larger share of the charter sector. Third, school choice depends on freely available information for parents and students to make informed decisions about where to attend, including potential long-term benefits. We add to the empirical research on charter school effects by using a doubly-robust regression-adjusted propensity score matching approach to evaluate the impacts of charter high school attendance on 9th grade behavioral outcomes and individuals propensity to commit crime and participate in elections as young adults in North Carolina, a state with a large and growing charter school sector.
