For many students in the 1990s, school is no longer a safe environment in which they feel free to learn. This brief is intended to dispel myths about peer sexual harassment and clarify the new realities of the phenomenon in schools. The brief also conveys the message that school administrators have a duty to foster a school environment based on mutual respect and to adopt a "no tolerance" policy toward harassment, sexual or otherwise. The brief outlines steps for recognizing peer sexual harassment (by deconstructing nine myths and explaining conditions under which schools will be held liable); preventing peer sexual harassment (by developing a comprehensive school policy); and enforcing the rules (by setting out the components of a model policy--investigation, documentation, and followup).
