This article concerns the problem of dangers relating to the school educational process, connected with the occurrence of the phenomena of the social exclusion of children and young people. Some results of the empirical research carried out on middle-school students from Zamość schools are presented, as well as the analysis of the research and some possible ways of solving the problems in question connected with the students’ cultural activity. In order to estimate the phenomenon of social exclusion, a special “index of a student’s resistance to social exclusion” was created. Three indexes of a student’s participation in the cultural life were defined: “an index of passive participation in the cultural life”, “an index of active participation in the cultural life” and “an index of the creative participation in the cultural life”. The results of the estimation of the regression models of the index of a student’s resistance to social exclusion in relation to the index of a student’s participation in the cultural life and other control variables were presented.
