In order to implement quality and successful teaching, it is necessary to establish classroom discipline and in order to achieve it, there are school rules that every student must follow. However, in schools there are students who do not respect these rules and repeatedly violate the house rules, and on the other hand there are students who stand out with their behavior and commitment to teaching. Therefore, the Law on primary and secondary Education in the Republic of Croatia regulates two basic categories of educational activities in school systems. These are stimulative and punitive pedagogical measures. Stimulative pedagogical measures are aimed at praise and awards, while punitive pedagogical measures are aimed at criticism and punishment and they are imposed on students for breach of duty, failure to fulfill obligations, violent behavior and other inappropriate behavior. Punitive pedagogical measures in primary school are warning, reprimand, severe reprimand and transfer to another school. The reason why they are pronounced is the increasingly common unacceptable behaviors in students, which are divided by severity into: mild, harder, tough and especially tough unacceptable behaviors. According to the Ordinance on Criteria for Imposing Pedagogical Measures, the purpose of imposing a pedagogical measure is to change the behavior of the student to whom the measure was imposed and to encourage responsible and appropriate behavior of other students. The imposition of pedagogical measures should encourage students to take responsibility, and in this way the student should develop a positive attitude towards school, school obligations, school environment, teachers and classmates. The imposition of pedagogical measures is based on the principles of gradualness, proportionality, fairness and timeliness. A study aimed at determining the role of teachers in pedagogical measures and the existence of libno and educational differences has been proven. Research data were collected by interviewing two primary school teachers.
