Since their inception in 1992, the number of charter schools has grown to more than 6,000 in 40 states, serving more than 2 million students. Various studies have examined charter schools’ impacts on test scores, and a few have begun to examine longer-term outcomes including graduation and college attendance. This paper is the first to estimate charter schools’ effects on student earnings, alongside effects on educational attainment. Using data from Chicago and Florida, we find evidence that charter high schools may have substantial positive effects on persistence in college as well as high-school graduation and college entry. In Florida, where we can link students to workforce data in adulthood, we also find evidence that charter high schools produce large positive effects on subsequent earnings.
