The education system, having unique opportunities to expand knowledge about other people who are different from us, their views, culture, as one of the most important tasks, puts forward the problem of forming tolerance among the younger generation. The relevance of this socio-pedagogical problem is due to the need to find effective means of forming tolerance among students. The study was conducted on the basis of the municipal budgetary educational institution "General education institution Gymnasium No. 11 named after A.N. Kulakov" in Krasnoyarsk. The sample of the study was 133 subjects. The female sample is 71 people, the male sample is 62 people, students of grades 9-11. The obtained data and statistical analysis confirmed the dependence of the level of tolerance of older adolescents on sex differences. Girls are tolerant, they are characterized by tolerant forms of behavior, while boys, on the contrary, are more often intolerant, both to the outside world and to people. With the help of Kendall's rank correlation coefficient, data were processed and compared using the methods "Level of subjective control" and "Tolerance Index". The data confirmed the relationship between the level of subjective control and the level of tolerance of older adolescents. Externals have a low tolerance for others, internals have a higher level of tolerance. In addition, the data showed that girls have a higher level of tolerance than boys.
