We estimate the causal effect of a high school diploma on criminal justice system contact for a set of people who previously exited high school but then attended The Excel Center (TEC), a network of high schools for adults. Compared to those who apply but do not enroll, students who enroll but exit without a diploma do not experience a decline in criminal charges. Criminal charges for students who complete a diploma, on the other hand, decline by 49% the year following application, an effect which largely persists for at least five years. These effects are sufficiently large to increase the cost-effectiveness of the program by 2-5 times. The pattern of effects also suggests that, beyond simple incapacitation, getting an adult high school diploma itself leads to lower contact with the criminal justice system. %K GED %K high school diploma %K returns to education %K human capital %K crime
