What teachers can do:

• Ask students about bullying. Survey students regularly.
• Ask students about their relationships. Know your students well, who they get on with and who they don't get on with.
• Build democratic classroom and school climates. Identify and grow student leaders who can make a stand against bullying.
• Be an informed consumer of anti-bullying curricula. There is no silver bullet.
• Remember that bullying is also a problem of values.
