For the successful implementation of the ideas of multicultural education in college, it is necessary to develop the educational environment in the institution, which is the interaction of the cultural and intercultural component in the relationship between students belonging to different ethnic and social groups. The purpose of our study is to identify and describe the characteristics of multiculturalism as a property of the educational environment. The article includes generalized results of the theoretical analysis and experimental study of multiculturalism as a property of the educational environment of the college. The diagnostics was carried out using survey methods and an expert assessment method. The analysis of the results of the study indicates that students of groups with the Kazakh language of instruction (hereinafter referred to as KL) have a pronounced ethnic identity, while students of Russian-speaking groups (hereinafter referred to as RL) have indicators of ethnic identity with an average level of intensity. At the same time, the tolerance indices for students of the KL groups are inferior to the similar indicators inherent to the students of the RL groups studying in Russian. Assessing the components of multiculturalism in the educational environment of the students of “Kazakh” and “Russian” groups does not meet the expectations of college teachers. College teachers have a slightly different view of the relationship between students of the two departments. The results of the study revealed the need for the reorganization of the management system in the College of Humanities, which in its present form does not initiate the development of active intercultural relations between students of the two departments (departments with the Kazakh and Russian languages of instruction), and at the same time does not satisfy the urgent need for the formation of the student body of college departments in accordance with chosen specialty, but not in accordance with the language of instruction. In conclusion, the authors summarize the results of the study of multiculturalism as a property of the educational environment of the college.
