The subject of this final paper is the organization and scope of work of the state administration in the Republic of Croatia, analyzed through the legislative framework with a focus on the modernization and reforms implemented in the Croatian public administration system over the past two decades. In addition to the organization and scope of work of the state administration, the paper addresses the tasks and normative powers of the state administration, state administration bodies, and issues related to public servants. By presenting the laws and by-laws governing the organization and scope of work of the state administration, the paper provides insight into the complex issues surrounding state administration, whose reform was one of the key elements in Croatia's accession to the European Union. The improvement of administrative capacities, better organization of public administration, increased openness and accessibility of the state administration, and raising the quality of administrative services are the most prominent goals in the reform of state administration in the Republic of Croatia. The new State Administration System Act was adopted with the aim of implementing the Government’s reform measures, which include depoliticization of the state administration, decentralization, digitization of office operations, and rationalization of the state administration by reducing the number of state administration bodies from 52 to 32, and establishing a professional management structure. The reforms carried out in the Croatian public administration system over the past two decades have improved its efficiency; the state administration and public institutions have become more open and transparent, and digitalization has improved access to public services. Despite the undeniable results achieved so far, further reforms of the state administration are of great importance for the development of a modern state administration, as the functioning of public administration significantly affects the country's growth potential and the well-being of its citizens.
