The article presents a pedagogical model of the innovative platform of supplementary education for the senior students of secondary and high school. The mission of the educational platform is to provide a versatile preparation of the members of educational community for the independent and successful realization of their life goals. The synthesis of the competency-based and cultural conformity approaches lies at the heart of the design of educational courses. The content of education includes a number of problem-plagued modules: "Humanistic Philosophy and Worldview", "Personal Development and Lifestyle", "Information and Thinking", "Communication and Interaction", "Project and Organization Management", "Body and Health", "Beauty in Nature and Art", and "Peoples and Countries".During the development of educational courses, the emphasis is made on the formation of the functional literacy (psychological, communicative, political, environmental, consumer, etc.) as the functional basis for the key and special competencies. The educational process consists of six stages: preliminary, primary, individual, group, leadership, and expert (club). The educational process is based on the participation of the education community members in the implementation of the socially significant projects: at first, in the role of performers; then-managers; and at last-experts and consultants. The course content and organization of the educational process provide for the formation and development of the key competencies of a contemporary person: informational-cognitive, civil-social, social-labor, lifestyle, culturalleisure, and personal-organizing.
