In an educational organization, a student is faced with a large number of complexes, ambiguous both educational and life situations that require him to have an adequate and conscious choice. At the same time, many lack an understanding of their social ideas and the ability to separate emotional relationships from rational interaction. The modern youth environment, due to its age, worldview and socio-psychological characteristics, is in dire need of sociocultural identification, therefore, it is more susceptible to transformational processes associated with the assimilation of value systems, norms that form certain forms of behavior. There is a substitution of traditional forms of public morals and value foundations, leveling cultural continuity, the threat of preserving the milestones of Russian history, etc. These aspects lead to an increase in forms of deviant behavior, manifested in deviation from legal and moral norms. There is a desire to participate in informal youth associations, which leads to increased aggressiveness, an increase in extremism in the youth environment. The origin of extremism is considered the intellectual and moral limitations of the individual, which testifies to the problems of education, both in the institution of the family and in the educational process. A socio-psychological study in an educational organization can identify categories of students who require targeted information, education and psychological and pedagogical impact in order to timely prevent deviant behavior, including extremist manifestations. The diagnostic technique «Violent Extremism Attitude Scales – VEAS» allows you to identify dispositions for extremism in the student environment in the early stages, and to introduce preventive measures in the educational process in a timely manner.
