The aim of the master's thesis is to clarify the concept of open clubs. Basic terms connected to an open club are defined in the first part of the thesis. Spontaneous activities and low-threshold approaches are the most important there. The principle of low-threshold approaches are typical also for other institutions, that are registered in law. It concerns low-threshold centres for children and youth. The origin, development, aiming and activities of these centres are described. The thesis explains open activities for young people offered by different leisure time centres. Also open clubs and Salesian centres offer these activities. The last chapter of this part shows basic differences between an open club and a low-threshold centre for children and youth. The second part of the thesis deals with a detailed analysis of the School Education Programme of a chosen centre carrying on an open club. The aim of the research is to find information about the open club in the document and evaluate the extent and the quality of the discovered details.
