Аbstract. The issues of tolerance in young people in the process of learning in an educational institution are analyzed. At present, representatives of different cultural traditions, principles of life are forced to share one geographical space. This rapprochement, as real experience shows, does not always proceed peacefully and calmly. Interethnic (intercultural) tension, right up to open confrontation, ethnocentrism, xenophobia - all this testifies to serious problems in modern social relations. There is an opinion that in spite of all the relevance and discussion of this topic in broad social science circles there are no unified approaches to understanding the essential characteristics of the phenomenon of tolerance, there is no understanding of who and how tolerant relations are possible, what are the mechanisms for achieving this goal, Some people see it as a kind of a panacea through which only it is possible to save and preserve civilization, while others believe that it serves only to symbolically hide and cure the real schism and indifference that humanity is exhibiting. A theoretical analysis of the essence of the concept of «tolerance» is reduced to the fact that tolerance by origin is a social category (arises and manifests itself in the process of human interaction with society, with man); it fixes a special (non-violent) type of relationship between a person and society. A characteristic feature of tolerance is the stability of manifestations: at the level of consciousness, it manifests itself in the form of an individual’s attitude, and at the level of behavior as a conscious action or deed, as co-creation. Often, researchers formulate such tasks of psychological and pedagogical activity on the formation of ethnic tolerance of students as the formation of a value attitude to one’s own and other ethnocultures; the formation of motivation for intercultural cooperation; fostering a positive attitude towards cultural differences, the development of intercultural sensitivity; development of skills and skills for effective interaction with representatives of different cultures in the spirit of peace, ethnic tolerance and mutual understanding. Therefore, an important condition for joint activities is the creation in groups with a mixed national composition of an atmosphere of inter-ethnic understanding and tolerance, where everyone, regardless of ethnicity, feels comfortable, open to interaction with others, where ethical standards of behavior in interpersonal communication are observed. That is, the cognitive and emotional components of tolerance are most significant when there are contradictions, clashes of values, dissent in conflict situations. Wherein a tolerant behavior is characterized by the ability not to actualize the conflict, which in turn is determined by the level of upbringing and education.
