In many countries across the world schools are no longer a safe place for both students and school staff. Violence in school is an issue scarcely studied in Serbia and there are few articles in domestic professional literature. At national and local level there are not developed strategies nor programs for preventing violence among students in our schools. There are no data about planned, systematic and organized prevention of violence in the practice of our schools. The data obtained by investigations indicate that it is necessary to apply adequate programs for preventing violence among students in our schools, despite the finding that violence in school is not that much conspicuous and serious problem like in other countries (USA Israel, Japan, Austria, Germany). On the basis of relevant literature review the present paper highlights some very popular and less notorious measures and prevention programs applied in various countries. The aim of the paper is to transmit basic and essential pieces of information so as to gain insight into diverse existing approaches to prevention of violent behavior in school hopefully to encourage our schools to pay more attention to preventing violence in school as soon as possible before it is too late.
