The details: The new guidelines recommend that a school team composed of teachers, guidance counselors, mental health professionals, coaches and principals "meet on a regular basis to engage in discussions, role-playing scenarios, and other team building and learning scenarios.

• The guide encourages school climates where students "feel empowered to share concerns with adults, without feeling ashamed or facing the stigma of being labeled a "snitch."
• It discourages the notion that student attackers have a profile: "There have been male and female attackers, high-achieving students with good grades, as well as poor performers. These acts of violence were committed by students who were loners and socially isolated, and those who were well-liked and popular."
• It encourages students to anonymously report "troubling behavior" through email, online forums, and more.
