In the text, in light of the theoretical assumptions of research on youth's sense of identity, I characterize the conditions of the social functioning of Polish ethnic minorities living in Belarus, Ukraine and the Czech Republic, and I discuss the results of research conducted among the students of schools with Polish as the language of instruction in those countries. Among the members of a national minority double or even triple identities often emerge, but problems with shaping one's identity are not uncommon as well. Among the identification profiles of researched students identification with "Polishness" was dominant. Declarations expressing bonds with the country of residence were also disclosed.
