Peer violence is a common problem in most elementary schools and occurs in different forms. It is important to distinguish between children's occasional teasing and conflicts that occur in play from intentional violence that is caused by the desire to hurt someone. Parents play a big role in every child's life, including in situations of violence. With their support and understanding, they build self-confidence in the child, in this way the child will know that he is not responsible for other people's violent and unpleasant behavior and will be more ready to react optimally. The aim of this research was to examine parents' opinions about the occurrence of violence among children in schools, to examine their actions in situations of violence (in which their children are involved) and to examine their opinions about the school's involvement in solving the problem of violence. The occurrence of violence among children was examined by parental assessment from three points of view: violence that was done to their children, violence that their child manifested, and violence that the child noticed (the role of an observer). Parents' opinions were examined using a questionnaire via the Internet, 120 responses from parents of children from the first to the fifth grade, from all over Croatia, were collected. According to the results, the highest estimated violence is in situations when the child notices violence, while the lowest estimated violence is manifested by the children of the questioned parents. The actions of parents in moments of violence proved to be very diverse and under the influence of various factors determined by the situation of violence in which their child found himself. Finally, the responses indicate that more parents are satisfied with the school's involvement, although the majority of parents "partially agree" with the stated statements.
