Main problem: Today, the opinion about inclusion as the most progressive (in comparison with integration) approach is being strengthened among the society, which allows any child, regardless of the type and severity of the disorder, to learn with their normatively developing peers. The introduction of inclusive approaches into school practice can be called one of the top priorities of the state educational policy of the Republic of Kazakhstan. Inclusive education will help to resolve the contradiction between the legally guaranteed rights of children with disabilities to equal access to quality education and the de facto inequality in its implementation. Inclusion must be systematic and focused, not spontaneous. Therefore, it is optimal to teach a child with disabilities within the framework of the system of continuous general education. The creation and effective functioning of this system is impossible without a trained teacher, who is a key figure in the implementation of inclusive education. Purpose: Substantiation and disclosure of the contradiction between the guaranteed right of children with IAD and equal access to quality education for the socialization of children with special educational needs in inclusive education. Methods: in the course of the research, descriptive, systematization and analytical methods were used in the application of theoretical concepts, government programs, and legislative acts in inclusive education. Results and their importance: The implementation of the research goal is facilitated by the use of an alternative to the classroom-based organization of the educational process for the progressive development of children with IAD, which allows them to study harmoniously, regardless of the type and severity of the violation, together with their normatively developing peers. The given pedagogical observation is the obtained practical result of this study. The development of the system of class-based organization of the educational process for children with IAD in educational institutions is aimed at forming an effective system for ensuring the comprehensive development of inclusive education.
