The corporate education system is implemented through sequential and step-by-step in-company training based on integrity of goals, objectives, functions, learning technologies, content structure of the training material, which add flexibility and vitality to the entire learning process with an advance reflection of reality. The definition of a corporate training center in terms of a systematic approach is formulated as a system in which training and development of personnel is initiated and managed by the company itself, carried out within the company and involves internal resources. Thus, training and professional development of managers is not just an element of organizational practice or type of activity of certain employees of the organization, but a full-fledged part of the development strategy of the organization and the entire existing organizational system. To implement this process, modern TNCs create corporate training centers in which training and personnel development is initiated and managed by the company itself, carried out within the company and involves internal resources. The algorithm of creating a corporate training center covers a number of stages, in particular: support by the management, legal and financial support; creation of organizational and pedagogical conditions; program and content implementation support and practical application of the personnel training system; control and reporting system at the same time; adjusting training plans and programs; personnel motivation. The study does not exhaust the problem of professional development of managers in transnational corporations. Issues of cross-cultural training of managers in the corporate education system, training of andragogues (training managers, instructors, coaches, tutors, etc.) for effective activity in corporate training centers remain relevant. Perspective directions for further research are also theoretical-methodological and didactic substantiation of talent management and development of their creative potential, development of tools for stimulation and retention of managers who have received training.
