Imagine a school where students hold doors, make welcoming comments, and offer to carry packages into the building. Or a school that's distinguishing feature is a culture of respect and helpfulness that manifests daily in positive student behavior. Or a school where even such seemingly small events as tornado and fire drills, which can be quite chaotic, are structured exercises that genuinely prepare the school community for potential emergencies. That school culture actually does exist at Dominion High School in Sterling, Virginia--a school with a diverse student body and significant socioeconomic disparities--but just seven years ago, it seemed like a distant dream. This article describes the five-step process that staff members consistently use to teach responsible behaviors at Dominion. Successfully teaching responsible behaviors is contingent on the collective efforts of staff members. A faithfully implemented schoolwide plan is essential to success. Dominion's experience indicates that explicitly teaching behavioral expectations prevents more serious disciplinary infractions from ever surfacing.
