Any student can be a victim of a bully.
Stanford University Medical Center research finds that as many as 90% of elementary age students are victims of bullying. http://www.sciencedaily.com/releases/2007/04/070412072345.htm.
In middle school and high school, bullies tease and socially isolate victims. They threaten them, use physical violence, harass and publicly intimidate them. Bullies destroy the personal property of victims. http://www.doe.state.in.us/legwatch/docs/Bullyingpaper2004session.doc
