The Law on Educaton in Primary and Secondarc Schools in the Republic of Croatia regulates two basic categories of educational activity in school systems. These two categories constitute encouraging pedagogcal measures that are focused on praise and rewards, and the negative pedagogical measures that are focused on criticism and punishment. The positive pedagogical measure is focused on students and emphasized the development of students self-discipline and their need for competence and good relationship with other students. They are imposed to students, classes or educational groups, who excel in learning, mastering or other activities. Negative pedagogical measures are imposed on student sin order to prevent and eliminate the negative consequences of a negligent attitude towards learning and work, for breach of house rules and other unacceptable behavior. Unacceptable behaviors can be divided into lighter, harder, tough and especially tough behaviors depending on their severity. Pedagogical measures in primary school are warning, reprimand, strict reprimand, transfer to the another school and pedagogical measure of the educational treatment of the extended professional procedure. The purpose of pedagogical measures is to encourage students to change their behavior, to take responsibility for their behavior and to anquire a positive attitude and attitude towards school responsibilities. Imposing of pedagogical measures must not be the result of retaliation or humiliation of the student. It must be based on fairness. Qualitative research was conducted to determine whether pedagogical measures have efficacy, that is, wheather their expression influences the change in students behavior. Survey dana were collected by interviewing pedagogue in primary schools. Four pedagogues were examined in four primary schools in the area of the village and the city. The research found that the efficativeness of pedagogival measures depends on the student. While some students have positive influence on the imposition of pedagogical measure and they change their behavior, it does not at all or not suffiviently affect the other students. Students who have been instructed to take a pedagogical measure should accept responsibility for their behavior and should influence their behavior to change.
