The theme of this thesis is the educational dimension of the school with an emphasis on the importance and role of moral education in the process of the overall development of school children. This paper describes the basic pedagogical terms, moral education and education, which we encounter every day and everywhere, and which are an integral part of the school system. We talk about the school as an educational institution, but the fact is that moral education and the educational function of the school are more and more often neglected and relegated to the background. In today's time, knowledge is considered a fundamental condition for the development of society, and it is known that knowledge without a moral component can be dangerous. Furthermore, great attention was paid to the teacher who, after the parents, has an important role in educating the children. What kind of people our children will become depends mostly on (moral) education. Considering this, raising moral, happy, responsible and successful children is certainly one of the most humane goals and tasks of the school.
