The comparative research of the adolescent’s school moral atmosphere perception in modern Russia Moral development at the stage of adolescence is difficult to overestimate. Global transformations of society in Post-Soviet Russia have affected the system of education. New type of non-state (private) schools have appeared along with existing widely spread state comprehensive schools and schools for specific purposes (profound learning of foreign language, mathematics, etc.). The aim of our study is to identify types of personal values of teenagers from two kinds of state schools, with ones from a private school being for contrast. In total 259 pupils from 8 to 11 forms, aged from 13 to 17, from three Moscow schools took part in the research: 131 girls and 128 boys. The research is based on the concept of the Just Community, offered within L.Kolberg’s moral development theory. The subtest of SMAQ questionnaire (Power et al., 1989) to study the teenagers’ perception of the moral atmosphere (PMA) in school communities, and S. Schwarz's questionnaire (Schwarz, 1999; Karandashev, 2004) to study the types of personal values of teenagers, were used. Similarities and differences in PMA of school by teenagers at different stages of Post-Soviet society in Russia were found (we compared present data with our data of 2000-2001 on the sample of 228 subjects). The research showed peculiarities of PMA and the teenagers’ system of values formation by private school pupils. The research concludes that values system becoming in adolescence is associated with the peculiarities of PMA in the secondary school. That fact permits to make up and realize correction programs. These programs are to optimize the formation of the system of teenagers’ values through transforming school communities into more democratic ones.
