Systematic work on the formation, improvement and development of human resources is the key to the effective functioning and stable operation of the entire civil service system in the country. Ongoing work on training is relevant both for the capital and for the most remote and smallest settlements of Ukraine. However, while in large cities, staffing is usually not a problem, it is a critical issue for the newly formed united territorial communities across the country. The reform of decentralization of power and the transfer of a number of competencies to local governments have revealed an acute shortage of people who would have the necessary competencies and knowledge to implement the ideas laid down in the reform. Some settlements of our country are actively continuing to lose their human potential. They suffer from urbanization, internal migration, demographic crisis, and so on. This is what makes it necessary to develop and implement a national human resources development program in order to effectively complete the implementation of decentralization reform and establish the further functioning of local government in newly created communities. The article theoretically substantiates the need to develop an effective system of human resources development of the regions of Ukraine, taking into account European experience and international standards in this area. The analysis and systematization of scientific sources revealed that the newly created united territorial communities, which were created as a result of administrative-territorial reform, faced the problem of lack of competent staff, which makes it impossible for them to perform new functions. The study analyzed the European experience in forming a system of human resources development, highlighted the current problems in domestic personnel policy, identified a number of recommendations for improving human resource management processes in Ukraine.
