Children's aggression in the home is often, but not always, related to their aggression at school. Research indicates aggression in school is most often directed at peers. Most aggression is displayed by male students and directed at male students. Female incidents of aggression appear at lower but not negligible rates. Assaults on teachers are not uncommon.
Research shows that weapon carrying in schools significantly varies by school setting.
The number of students carrying a weapon in some schools is much higher than in other schools. Children's physical aggression in schools is important not only because of the harm it inflicts, but also because it has long term consequences for settings beyond the school. For instance, consistent physical aggression by boys in schools predicts later antisocial acts, delinquency, and violent offending in the community. A proportion of boy fighters have already emerged during kindergarten. When the fighting persists through the first part of elementary school, these boys are highly likely to continue to fight in later grades.
