The primary purpose of this diploma thesis „The Importance of Innovations in Education with an Emphasis on Vocational Education“; as well as the related research is, just as the title suggests, to present the importance of innovations in the public sector with a special emphasis on innovations in education. The paper follows the course of research into the issues of innovation in the public sector and the mission, vision and goals of the research itself. All of the terms relating to the public sector in Republic of Croatia as part of the public sector of the European Union and the organizations associated with them that also affect their work are presented in the thesis. The chapter that describes innovation also presents the definitions of innovation, types of innovation, innovation in the public sector and the life cycle of innovation. Innovations in the public sector are very important and their importance affects the private sector as well. The paper focuses on a specific branch of the public sector, namely innovations in education and schooling. The paper also deals with the National Education System Development Plan for the period up to 2027 as part of innovations in the public sector and the education sector. Innovations implemented in vocational education are listed and explained in the paper, which is why they belong to the most represented innovations in the education system. Without the introduction of these innovations, that part of the public sector would act completely differently, and in the future would be less attractive and promising for the development of the entire sector. At the end of the thesis, an analysis and assessment of the potential that innovations have in the public sector and assessments of their importance and implementation in the future are presented. SWOT and PESTLE analysis are presented as one of the most significant, well-known and most widely used analyses.
