This work is about leisure educators' views on educational quality in large groups of children. School centers will contribute to children's development and learning through meaningful leisure and leisure educators' contribution with a high educational quality. There are a lot of discussions and writings about growing groups of children. How are the leisure education and its quality affected by increasing children's groups? It sparked my interest and therefore I wanted to examine this more closely how it might look in the leisure activities. The aim of this work was to examine leisure educators' perspective on how the educational quality is affected by large groups of children and what is considered of leisure educators' as a high educational quality. To answer my purpose five interviews was made with leisure educators' in different parts of Sweden and also by studying the theoretical foundations and literature for school centers and leisure education. The results of the interviews reveal, among other things, that leisure educators' feel that the large groups of children affects the quality of teaching at many levels. And that the group of children complicates the implementation of the commission and the activities of leisure educators' try to pursue. In the theoretical part it’s about the school center and its activities, and the leisure education the leisure educators are working with.
