These are the family, in the first place, the extended family, friendly, neighborhood, children's school, peers, adults, mass media and many other macro and micro environments. In theoretical terms, a topic is considered for the socialization of the child's personality at the age of 6-7 years, the preparatory group in the kindergarten.

Introduction:
Inclusion, inclusive education, is expressed in the reorganization of policies, practices and culture in Bulgarian education so that it can meet the diverse educational needs of students, encouraging them to participate actively.
Education is a constructive force, but at the same time it can reproduce existing inequalities and practices of exclusion in society. In order to stop this process, it is necessary to start with education. In the beginning, internationally, inclusive education as a philosophy was focused entirely on children with disabilities. In addition to disability, gender, ethnicity, language, socio-economic status, and many others are added to the reasons for exclusion.

Methods:
Theoretical background:
The developed experimental model is an option for enriching the educational process in the preparatory group for school. It complies with all normative documents regulating the pedagogical interaction with 6-7-year-old children in our country, in Bulgaria. The emphasis is in the educational field "Surrounding World" with the four cores "Self-affirmation and communication with others", "Social and health environment", "Cultural and national values" and "The world of nature and its protection".
The experimental model aims to form, expand and enrich social competence, through inclusive education, of 6-7-year-old children attending a preparatory group with a half-day, full-day or weekly organization of municipal or private kindergartens.

The subject of research is the level of social competence of inclusive education and the effectiveness of the proposed methodology for development and continuous improvement in 6-7-year-old children attending a preparatory group with half-day, full-day or weekly organization.
The design of the experimental study is divided into: Pilot study; Finding experiment; Forming (training) experiment and Final (control) experiment.
