The first day of school is a big day in the life of a preschooler. It is completely natural for children to look forward to new experiences, cheerfully choose pencil cases and school bags, shop for new slippers for school hallways and to look forward to the days that follow in school desks. No, these school desks can also cause a child stress. Issues such as constant sitting, going to the toilet, heavy school bags and the feeling of losing freedom and independence are just some of the ones that plague future schoolchildren. When it comes to situations in which they cannot help themselves, children turn to adults for help. Parents, although excited about the new step their child will take, may often wonder if they are ready enough for a new step in their child's life, and if they have done everything to make their child ready, which can also cause stress and anxiety. Parents ’attitudes and experiences are passed on to the child, so it is important that when they talk about their attitudes and experiences, parents speak in a positive tone. An educator is a person who actively participates in a child's life spent in kindergarten. One of his roles is to teach the child socialization, to develop empathy, to teach child how to express his emotions and feelings, to teach child to wait and share with his friends from the group. In this paper, I will address the issue of the role of educator in the process of a child's transition from kindergarten to primary school. I will talk about the procedures for the transition from kindergarten to primary school and the educator's role in them. In the second part, I will list those examples that I consider to be examples of good practice and come from European countries.
