The preschool teacher is the key to the quality of the educational process. His beliefs, attitudes and knowledge create a picture of a child, respectively his implicit pedagogy. Everything the preschool teacher does is consistent with his knowledge, attitudes, and beliefs. The preschool teacher has many roles in the preschool institution, one of which is creation of curriculum. The curriculum is always in the process of being created by all individuals in the educational institution. The preschool teacher creates it according to the child's interests and based on child-learning because the children gain knowledge in their material and social environment. In order to work with children, the educator acquires the skills and knowledge required for quality work during his education. With the development of society, there is an increasing need for preschool institutions. With the emergence of the first forms of preschool institutions, the first forms of education of persons working with preschool children appear. Educational educators have been formed over the last three centuries and now in Croatia we have undergraduate or professional studies for nursery school children and preschool age. This work presents the education systems of preschool teachers in Croatia, Slovenia, Poland, Greece, Italy, Germany, Finland and England. It is about official education guidelines, the necessary qualifications of staff and the head of pre-school education and vocational training in the countries mentioned.
