The paper discusses the role of teachers in the inclusion of migrant students and provides some suggestions for the active engagement of teachers in developing intercultural education, with examples from Slovenia. To support teachers who develop intercultural competence among all students, it is important to include concrete learning objectives in the syllabuses, in the framework of which teachers will be able to teach about social diversity. It will also be necessary to introduce content about multiethnic, multilingual, and multireligious society into the academic programmes, so that (future) teachers are more prepared for a diverse school environment and the development of an intercultural society.
