Effective activity of public authorities guarantees socio-economic development and effective functioning of the state as a whole and individual territorial-administrative units. The question of the competencies of civil servants in this aspect comes to the fore since the effectiveness of their work, the level and quality of the provision of administrative services, ensuring the functioning of the social sphere, the implementation of various development and cooperation programs, etc. will depend on them. In the context of the modern administrative reform in Ukraine, announced by the President, leadership becomes the leading element of the success of the further development and modernization of the civil service and service in local self-government bodies. That is why the development of public managers’ leadership competencies is considered a systemic phenomenon built based on analysis, assessment, and plan formation, with further development prospects by the position held and its level in the organizational system of the civil service. The issue of defining leadership competencies, their assessment, and various methodological approaches to their development allows us to assert the imperfection of the existing system. Nevertheless, the training of leaders-managers should be based on the principles of systematicity and analyticity, on clear and reliable theoretical and logical-methodological provisions. At the same time, identifying and training leaders is a complex process that should be considered as one of the specific types of psychological and pedagogical activity. Moreover, in this sense, the problem of organizing the training of leaders is closely related to the systematic selection of rational methods and methods, methods, and pedagogical technologies adequate to the goals and expected results. After all, leaders’ professional training and personal development should first be aimed at their future practical activities, in which the training results will be realized.
