Dostoyevski: "A society that is insensitive to tyranny is poisoned." Peer bullying is one of the most common violent behaviours among children. There are different types of bullying. Since students who are exposed to bullying cannot pay attention to their lessons and make efforts on how to avoid being the target of bullies, their success in school decreases. Some of the students do not want to continue school due to being exposed to bullying. Determining the types of bullying behaviours in schools is important in terms of the measures that can be taken regarding students' low academic achievement and low motivation. Bullying behaviours in schools may differ according to countries, cities and even residential areas within the same city. For this reason, it is aimed to identify bullying behaviours in schools of different countries and cities and to reduce these behaviours.
