Violence is a phenomenon that is ubiquitous in society. One of the forms of violence that we encounter every day is peer violence among young people. That kind of violence is present in school corridors, in the school yard, on the way from home to school, and on playgrounds. Violence is happens when one person decides to hurt the other with the intention of causing harm. It can be about emotional injury, inflicting physical injury or inflicting social damage by which a person wants to be expelled from society. Children and young people are often insecure about the definition of peer violence. Peer violence often takes different forms, and all these forms have one thing in common: they pass personal boundaries of permissible behavior. When it comes to peer violence, there are three types: physical, verbal, and relational violence. Violent behavioral patterns are learned from the parental model. It's up to the parents to influence that child so that he doesn't become a victim of violence or, in the worst case, an abuser. It's necessary to react to peer violence on time. This problem is often ignored and the blame shifts from one person to another. A large number of children are exposed to violence and violence should cause increased concern not only in schools but also in the families of young people. Parents, teachers, professional associates, educators and the local community are involved in preventive programs for the prevention of violence and the cooperation of the mentioned people is essential for the prevention of violence. Violence can often cause consequences for a child's physical and mental development and for his education.
