This report provides evidence of a critical link between values and success among youth at risk of failure in school and life. Success-related outcomes include academic success and responsible behavior with respect to drugs and sexual relations. The report examines research evidence linking student attitudes and values to successful outcomes in the following four broad areas: (1) goals; (2) control over goals; (3) responsibility; and (4) conformity to societal norms. Successful intervention strategies and programs that promote positive values and attitudes in students are discussed and described within the following categories: (1) directly instructing students in values; (2) providing experientially based opportunities; (3) role playing; (4) incentives and opportunities; and (5) providing good role models. The report presents the following recommendations: (1) values approaches should be integrated into each school's overall program of student improvement; (2) schools should develop comprehensive strategies that address home and community, as well as school, influences; (3) opportunity must be recognized as an essential component of many values strategies, and extra resources for supplemental instruction, personnel training and supervision, smaller class or group size, and home and community outreach efforts must be provided; (4) schools must design individualized tactics appropriate to achieving specific outcomes; and (5) strategies should be consistent and long-term. The report includes one figure. (Af).
