The subject of our research is of great relevance due to the fact that in the current context, when educational environment is marked by its multicultural and multiethnic features, the issue of formation of ethno cultural competency is very important. Thus the goal of this article is to discover the potential of museum pedagogics and its role in the formation of ethno cultural competency of future educators. The principal methods of the research are theoretical and practical ones, which allow to have a comprehensive look at the formation of ethno cultural competency of future educators. The article introduces the viewpoints of scholars and experts regarding such concepts as "multicultural educational environment", "museum pedagogics", "ethno cultural competency"; it detects common approaches, as well as differing ones, to the potential of museum pedagogics and its role in the formation of ethno cultural competency of future educators. The results of the research--which help to identify the level of ethno cultural competency among the students of the department of psychology and pedagogics--will help to make corrections in our efforts to use the potential of the museums of Yoshkar-Ola and Mari State University in the process of training of future educators.
