Thesis aims was to examine and answer the question “What do the examples of good practices of early childhood educators tell us about the motivation, implementation process and challenges educators face in their work?” The research sample consisted of ten educators conducting early childhood and preschool education in kindergartens in Primorje - Gorski Kotar County. The research was conducted in the form of a semi - structured interview. The results show that educators who are examples of good practice in sustainable education in early childhood and pre-school education estimate their role in the field of education for sustainable development as extremely important. Their living environment and personal beliefs impact their motivation. Most educators cite their own childhood environment as an influence on the development of sensitivity to the area of sustainable development and their current commitment to the concept, while college education significantly accentuated the importance of sustainable development. Advocacy for human rights, respect for different cultures and social differences, nature and environment preservation and developing a sense of accountability for one's own actions are some of the goals that educators want to achieve and encourage in children. Support, resources and cooperation in the implementation of education for sustainable development most often comes from the institution itself, i.e. the director, the local community, other educators, educational experts and the parents of the children. Nevertheless, educators still face certain challenges in their work. Improvements in the implementation of education for sustainable development could be achieved by raising the awareness in the university faculties about the importance of the concept of sustainable development. In order to improve this process, educators believe that it is necessary to improve the educational competences for the implementation of sustainable development in educational work and to make the concept of sustainable development more visible in society.
