Article compares the ways in which the cross-border co-operation between schools is conducted in all six Euroregions on Czech-Polish borders. The main research methods were based on analysis of the microprojects, which were implemented in these euroregions. Research surprisingly declined initial hypothesis expecting the most frequent use of INTERREG funds in cross-border co-operation of schools in the Euroregion Těšín/Cieszyn Silesia, due to the historical links between both parts of the Euroregion and almost non-existing language barrier. It also expected its lowest intensity and quality in the Euroregions Nisa-Nysa-Neisse. Research showed that certain "default setting" of Těšín/Cieszyn Silesia Euroregion has not automatically brought along the highest number of co-operation activities in the field of education - only partially in the use of "big" programme, jointly with subject from Euroregion Silesia, but it was absolutely different in the use of microprojects'scheme managed by Euroregion. This must be attributed to the fact that co-operation of schools has not been understood as a priority. The more important element than "default settings" must thus be seen in the active approach of CBC stakeholders - mainly in the euroregional secretariats.
