In school systems, dimensions of educational activites are regulated by the Law on primary and secondary education in the Republic of Croatia and they can be divided in two categories. In first category are pedagogical measures whose aim is to commend and reward. In second category are pedagogical measures whose aim is to criticize and punish. Pedagogical measures of criticize and punish are imposed to the students for the violation of their duties, not accomplishing of their duties, violent behaviour and other inappropriate behavior. Pedagogical measures in primary school are warning, reprimand, strict reprimand and transfer to the another school. Pedagogical measures are imposed for violent behaviour which are divided on lighter, harder, tough and especially tough ones. Purpose of imposing of pedagogical measure is to influence the behaviour of person to whom is measure imposed and to encourage this person for responsible and appropriate behaviour to the other students. Pedagogical measures should motivate students in the way that they will adopt positive attitude to the school responsibilities and environment. Imposing of pedagogical measures is based on principles of progressivity, throttling, fairness and timeliness. A qualitative research usign a case study method was conducted. For the purpose of the research students, with imposed pedagogical measures, their teachers and pedagogue of primary school in Radovan were interviewed. Reseacrh goal was to explore how pedagogical measures implicate students behaviour and to verify if all students with imposed pedagogical measures have changed their behaviour. Research conclusion is that every pedagogical measure has different influence on different student. While imposed pedagogical measures on some students has positive impact and ther behaviour is positively changed, for some other students this can´t be affirmed and there students think they didn´t deserve imposed pedagogical measures. Students, to whom some pedagogical measure is imposed, should understand meaning of imposed measure and this measure should change student´s behaviour.
