Project SUCCESS (Schools Using Coordinated Community Efforts to Strengthen Students) is designed to prevent and reduce substance use among students 12 to 18 years of age. The program was originally developed for students attending alternative high schools who are at high risk for substance use and abuse due to poor academic performance, truancy, discipline problems, negative attitudes toward school, and parental substance abuse. In recent years, Project SUCCESS has been used in regular middle and high schools for a broader range of high-risk students. The intervention includes four components: The Prevention Education Series (PES), an eight-session alcohol, tobacco, and other drug program conducted by Project SUCCESS counselors (local staff trained by the developers) who help students identify and resist pressures to use substances, correct misperceptions about the prevalence and acceptability of substance use, and understand the consequences of substance use. School-wide activities and promotional materials to increase the perception of the harm of substance use, positively change social norms about substance use, and increase enforcement of and compliance with school policies and community laws. A parent program that includes informational meetings, parent education, and the formation of a parent advisory committee. Individual and group counseling, in which the Project SUCCESS counselors conduct time-limited counseling for youth following their participation in the PES and an individual assessment. Students and parents who require more intensive counseling, treatment, or other services are referred to appropriate agencies or practitioners in the community.
