The transition from kindergarten to school is one of the biggest changes that children experience in their life. This means entering a new and unexplored world, which leads to a number of social and emotional changes in a child’s life. Therefore, it is the parents’ responsibility to prepare their children for this central transition as well as to ensure that they go through it without difficulties. Consequently, all children have different perceptions on the subject of school, which depends on their surrounding and the approach that others have towards the child. Additionally, their perception is also a result of the information that they have acquired regarding possible changes that they might experience while starting school. Furthermore, in the last year of preschool education, all children undertake an assessment done by the expert committee, who evaluate the child’s psychophysical ability and readiness to start school. The preschool teacher prepares and conducts different activities and games, which encourage growth and holistic development of children. Thus, the teacher prepares the children for future challenges that they might encounter in this transitional period, while encouraging them to accept themselves and other members of the educational group. Most importantly, the curriculum of the institute is crucial due to the fact that it allows children to state their own opinion, socialize and learn how to accept and deal with success and failure. In addition, one of the main factors of a successful transition from kindergarten to school is the cooperation between the family, kindergarten and school. The relationship between the parents and the teacher should be based on cooperation and good intention with the aim of facilitating the transition of the child from kindergarten to school as well as improving the practices for future generations. However, building this type of relationship requires determination from all sides, which is not visible to the extent that it should be in Croatia. The main reason behind this is visible from poor communication between the kindergarten staff and the school, which results in uncertainty, unpreparedness and a stressful enrollment of a child in school. Most importantly, acquiring certain competencies should be encouraged as well as a positive cooperation between the members of the child’s community. Therefore, it is crucial to observe the child’s development with an individual approach in order to ensure that a child continues further education successfully.
