Being in charge of a class includes a whole range of formative and educational functions and tasks that fall exclusively under the domain of homeroom teachers. It is not an easy task to become a homeroom teacher in primary or secondary schools and it requires absolute dedication to the obligations in class, as well as in the entire school. Homeroom teachers quickly become the right-hand assistants for students’ parents, as well as a connection between students’ families and the rest of the school team. Homeroom teacher’s tasks arise from certain formative and educational goals. They are regulated by law and prescribed by regulations and legal provisions, and were analyzed and mutually compared after conducting empirical research. However, being a homeroom teacher does not only mean following the rules stated in these documents. A determined and conscientious teacher can have a large influence on the quality of students’ learning if he or she employs proper competences. Of course, homeroom teachers can’t acquire competences over the course of one day or night – their acquisition requires investment of additional efforts and personal development, while the results become visible with time.
