The aim of this thesis was to analyze the possibilities of prevention of cyberbullying among children and young people carried out by elementary schools as part of their work. The paper consists of a theoretical part that includes the definition of the term cyberbullying, its most common forms and consequences. Special emphasis is placed on some of the ways to prevent electronic violence in Croatia, challenges in prevention and the importance of evaluating such programs. The second part of the paper includes a research part in which preventive programs of six primary schools in Koprivnica-Križevci County were qualitatively analyzed with an emphasis on cyberbullying. In addition to the analysis of preventive programs within the school curriculum and annual plans and programs, a semi-structured interview was conducted with students from two elementary schools from the sample in order to gain a deeper insight into the experience of the cyberbullying prevention program of their schools. The results show that schools generally have detailed programs for the prevention of cyberbullying and most often implement them during the Safer Internet Day and through various activities. Part of the sample of schools implements cyberbullying prevention activities through Computer science classes throughout the year. As expected, although the methods of preventing cyberbullying do not coincide in all schools, prevention programs are actively implemented in all schools.
