The beginning of the final paper presents the basic concepts of the European Union. The history of European integration is presented in a simple way as well as its dissemination. Also, The functioning od the European Union is theoretically explained as well as their basic institutions for the functioning of the European Union. Croatia's way of membership and the changes that followed have been presented in the final paper. Then begins the main topic of the final paper The importance of education in European Union, which covers the segments of the human capital, young people in the labor market and their future in Croatia. A major part of this story is the mobility that represents one of the main positive changes after Croatia joins the European Union. Mobility is meant for the purpose of education and learning, but also freedom of work and free boundaries in certain European Union member states. In the research on education carried out in the second part of this paper, results are not surprising for Croatia since they last for some time. Only in one (out of four observed) segments, Croatia is more advanced than Slovenia and Hungary. But that is precisely why Slovenia and Hungary are countries with whom Croatia should work closely and observe their system of education. The ultimate goal is to connect education efficiently with the labor market, while strengthening lifelong learning. It is also a recommendation to make changes in the functioning of institutions, educational systems and programs and their cooperation with the common goal of improving education and youth status in Croatia.
