The successful formation of partnerships of adolescents is conditioned by certain factors and elements of educational environment, contributing to the formation of motivational-value, cognitive and operational-activity components of personality development of children of this age category. The peculiarities of the influence of this environment have a certain specificity associated with the conditions of formation of its structural components. Due to the action of these elements of the educational environment, certain age characteristics of adolescents are formed, which are necessary to ensure the effective principles of partnership, which will affect personal development and further development of academic achievement. Taking into account the importance of considering the theoretical aspects of determining the characteristics of the educational environment of adolescents, which determines the formation of their partnership, the study of this issue is considered relevant and will ensure the development of scientific thought. The purpose of the article is to systematize the approaches to defining the essence of the concept and structure of the educational environment of adolescents as a sphere of development of their partnership. Research methods applied: a systematic approach, which is used to systematize the provisions of scientific views related to the evaluated issues; comparative method used to compare the approaches of scientists. The study presents a systematization of approaches to defining the essence of the concept and structure of the educational environment of adolescents, which contributes to the development of their partnerships. It is proved that the main essential features of the concept of educational environment of adolescents, which contributes to the development of their partnerships include: structural feature (in the interpretations of the authors, mainly determined by reference to certain components of this phenomenon), performance feature (emphasis on areas of influence - behavior, development of value beliefs, etc.), organizational feature (indication that the subjects of the environment provide active assistance in the development of certain skills, qualities of adolescents), subject-oriented feature, which involves the formation and development of the educational environment of adolescents in the context of subject-subject direction (humanistic approach ). The composition of the conditions for the formation of this phenomenon is determined, which include general categories, in particular: objective, specially (artificially) created, static, dynamic. The interpretation of the studied concept is formulated, which is based on taking into account the list of basic essential features and categories of conditions of formation of the educational environment, which promotes the development of their partnership.
