The paper presents research findings concerning desired parental activities for peer violence prevention. An instrument was created for the purpose of this research, and study sample comprised 480 participants, including 170 parents, 94 teachers and 206 students. Activities perceived as more important were open communication and greater control of children’s behavior, while parents’ participation in school was assessed as less important. The “School without violence” program was recognized as a significant resource for empowering family activities in peer violence prevention. This implies that it is important to implement family support programs and to develop parents’ skills.
