The Teen Involvement program is implemented primarily by youth, with guidance and direction from qualified, concerned adults. It aims at preventing substance abuse by utilizing positive youth-to-youth communications. Junior and senior high school students are trained to discusses causes of drug abuse and ways of preventing it with students in grades 4 through 12. The program's creators have sought to involve youth in an effort to improve decision-making capabilities, develop better-organized values and reduce and prevent substance abuse among young people. Selected students, called Teen Advisors, serve as role models for younger students. After carefully supervised training, they visit elementary school classrooms on a regularly scheduled basis. Similar programs can be started by interested administrators in their own settings. (Author/BP)
