The article shows that the applied preventive measures against aggressive pupils’ behaviour at school are basically oriented towards the punishment of the guilty and are valuated ambiguously. The variety of provided measures is rather wide – from warning to excluding from school, however, the most often there are applied the softer measures (warning). Radical measures are applied very rarely since they would damage school‘s prestige. Although the proposed preventive measures are different – some are more educational character (suggestions how to involve, interest children, to provide psychological support), while others are more administrative – managerial character (to introduce the positions of a policeman and nursery inspector at school), but they all are essentially oriented towards both - the punishment of the guilty and the prevention of such activity. The efforts of school administration and the efficiency of the applied preventive measures are evaluated by teachers, pupils and their parents quite critically but they are not likely to take more personal responsibility and commitment.
