Today the issue of fundamental education-based approaches to higher education policies development is indisputably important, especially for the system of education in the Republic of Tatarstan (which is a subject of the Russian Federation with the biggest share of multi-confessional and multi-ethnic groups). Kazan Federal University is among universities with the largest number of students from different countries and the highest concentration of representatives of different peoples in academic groups. The author proposes a model of humanistic socialization and argues the hypothesis that only systematic humanistic socialization through a differentiated approach to teaching can help to improve the modern system of higher education. The research aims to prove that humanistic socialization should be based on multicultural approaches and the combination of interethnic values to develop tolerance among students of different ethnicities. The objective is to demonstrate the potential of education-based approaches to help students adapt to the demands of the public life in the globalized world. The key result of the research is an attempt to reconsider the gained experience in the field of humanistic education at the university and, as a result, shape a humanistic type of personality, a true intellectual who has not only professional literacy and competences, but also a high level of moral culture, social knowledge and a developed sense of responsibility for social, humanistic and spiritual consequences of his activities.
