The usually negative relationship between school bonds and juvenile delinquency implies that adolescents with strong ties to school are less likely to engage in delinquency. Still, it is not always clear whether the impact of school bonds on delinquency is direct or mediated by other, more proximate causes. This article examines the dynamic interrelations between social bonds and the acceptance of legal norms over the course of adolescence. Results reveal that school bonds directly affect the acceptance of legal norms, but not delinquency. However, norms are directly and reciprocally related to delinquency. Therefore, school bonds can be considered an indirect preventive factor for delinquent behavior. Moreover, the closely related school bond and norm dimensions share a common developmental pattern during adolescence.
