The aim of this research was to determine the kind of attachment to school, perceived peer pressure and self-esteem of students with regard to the use of the half-day stay service. The research was conducted on a sample of sixth, seventh and eighth grade elementary school students in the Krapina-Zagorje County and the City of Zagreb. A total of 103 students participated in the half-day stay of the Center for the provision of services in the Zagorje community and the Dugave Center, as well as students of the Bedekovčina Elementary School who are not users of the aforementioned social service. The research was carried out in elementary schools and half-day schools, where students filled out a paper-and-pencil questionnaire. 53.4% of the students who participated in the research were included in half- day stays, lasting several months and up to more than 4 school years. The sample was convenient. The results showed that students with a higher level of self-esteem also have a higher level of attachment to school. As for the examination of differences, it was shown that students involved in half-day care show a lower level of self-esteem and a lower level of attachment to school. Also, it was shown that boys show a higher level of perceived peer pressure, but no differences were shown regarding the class the students attend. Differences in attachment to school, perceived peer pressure and self-esteem of students regarding the time spent in the half-day program did not prove to be statistically significant, nor did the connection between peer pressure and self-esteem.
