Public services are a complex concept that includes a range of different activities, various entities that perform these activities, and various forms of organization and delivery of these services. In the context of public services, the concept of public interest is crucial, which involves meeting general needs determined by the community through laws due to the importance of certain activities for society. Education as a public service in the Republic of Croatia plays a fundamental role in shaping society and ensuring equal opportunities for all citizens. The education system in the Republic of Croatia is organized into several levels, including preschool education, primary and secondary education, and higher education. The Constitution of the Republic of Croatia guarantees the right to education to everyone under equal conditions and according to their abilities. The education system in the Federal Republic of Germany comprises five levels: primary, secondary I, secondary II, tertiary, and quaternary levels. In Germany, early childhood and preschool education is provided to children from 0 to 6 years old, and secondary education includes two levels: secondary I and secondary II. After the introduction of the Bologna Process, higher education in Germany adapted to a two-tier study system, which allows for greater mobility and transparency of qualifications within the European educational space. Adult education in Germany, as in Croatia, is an important part of the education system and is focused on lifelong learning. The main purpose of adult education is to improve the skills of employed and unemployed individuals and to support adaptation to changes in the labor market. Adult education covers a wide range of programs, including languages, IT, arts, and professional skills, and is conducted in community colleges, vocational schools, and specialized institutes.
