Schools are social environments where students learn to socialize and participate in society. While the school environment aims to enhance the student socially and psychologically, there can be some problems in achieving these goals. One of the biggest issues is peer bullying. Bullying is the practice of physical and psychological pressure from larger individuals or groups that are repeated to less powerful individuals and groups (Olweus, 1993). There is a systematic misuse of perseverance and power in bullying, and there is also a power imbalance (Rigby, 1999). The frequency of bullying varies depending on the country, culture, student age and the measurement tools used. In addition to the role of the student's personality, family and cultural characteristics in bullying behaviors; The structure and size of the school, the attitudes of teachers and administrators, and the school environment have an impact. Worldwide, bullying is on the school education agenda. According to UNICEF 2020 data, half of the world's youth are victims of peer bullying in and around school. Although anti-bullying programmes have been discussed for some time, this issue has recently been raised in Turkey. The statistics in our research will show that bullying affects many students in our country. Although included in the counselling programmes in Turkey, a specific preventive programme is not used. The aim of this study is to compare school-based programs, which are considered to be successful in the world, and to examine their characteristics. Keywords: Bullying, KiVa , OBBP, ViSC, NoTrap,
