In this research we have tried to identify typical patterns of young people's behavior in their spare time and to use these patterns in order to group our subjects regarding their interests and preferences. Main-component analysis showed that it was possible to find different patterns of secondary school students' behavior in spare time as well as that the identified models could be the criteria for grouping them. Five patterns have been identified describing youth orientations towards their free time: academic orientation, orientation towards sports, orientation towards entertainment, orientation towards spending time going out and orientation towards music and computers.
