This article describes a school-based youth-driven teen dating violence prevention project. The project objectives are to provide opportunities for students to plan presentations and activities; develop knowledge and awareness about unhealthy gender norms, seen as an important root cause of relationship violence, particularly for teenagers; and identify ways to cope with and influence their environment with respect to this issue. This project was conducted in a rural Wisconsin community over the course of 5 years. It started as a multischool "drop-in" program with students from various high schools but eventually evolved into a youth action team at an alternative high school as a for-credit service learning class. Evaluation findings show the project to have promise in changing individual attitudes and beliefs while promoting bystander intervention. This youth-led health approach provides excellent opportunities for youth to become involved and empowered, and collaborating with schools can also be a successful strategy. Because unhealthy gender norms are so deeply entrenched, it is important to document and celebrate the smallest positive shifts in attitudes and behaviors. (Contains 4 tables.)
