Today, social partnership is interpreted as a way to integrate the interests of public relations subjects. Therefore, the issue of developing partnerships between the subjects of educational activities is relevant, as the education system in modern social transformations is an area of common interests activation. The purpose of the article is to determine the stages and levels of establishment of social partnership of secondary education with the community. The following research methods were used: the method of comparative analysis - to determine the current state of the problem of forming a social partnership in the education system; systematization, integration, comparison - to theoretically justify the stages and levels of development of relations between the subjects of social partnership. It is established that social partnership depends on the subjects united by a common goal; it has a structure that contains the content and types of interaction between partners. The content of social partnership is determined by the purpose and objectives of the institution, the department of education, the strategy and tactics of the development of the secondary education institution. The kind of interaction indicates how the partners cooperate, agree on plans and implement them. The effectiveness of cooperation between the partners is determined by the following criteria: the activity of partners in defining the goals (short and long perspective) and planning joint activities to achieve them; responsibility for the joint result; the principles of building the relationships: trust, mutual respect, openness, sincerity, honesty, etc. In total, there are twelve procedural components to building a partnership: situation assessment, partner identification, interaction building, management planning, provision of resources, implementation, measurement of results, evaluation, adjustment and refinement, creation of an institutional basis, continuation or completion. The establishment of the mechanism of interaction of the secondary education institution with the community is carried out in stages. Each stage of formation of the system of social partnership is characterized by a certain level of development of relations between the partners, availability of forms and methods of dialogue between them. The subjects of social partnership achieve effective cooperation, commonwealth, if their relations pass to the last stage of their development − the stage of creative interaction. Based on the transformation of the relationship between the partners, the levels (initial, intermediate, high) of the development of social partnership are established. At the same time, each school individually, according to its own needs and the needs of the local community chooses areas of cooperation with social partners. In the process of joint activities, social projects are implemented, public initiatives are implemented, the public is involved in school management, which contributes, in general, to the development of both the educational institution and the community itself.
