This scientific article explores the growing importance of teachers developing their intercultural competence in response to globalization, migration, and population diversity. Intercultural competence is considered a pivotal domain within the European framework, encompassing personal, interpersonal, and intercultural skills, as well as all aspects of behavior. It enables individuals to adeptly and constructively engage in both social and professional spheres. The article presents the current state of intercultural competences among teachers within general educational institutions, along with the provision of solutions and opportunities for continuous training in the intercultural field. To effectively contribute to the enhancement of an intercultural school environment, teacher professional development programs necessitate careful attention to their theoretical framework, content, and format. Among the specific objectives of the proposed course are: attaining knowledge and understanding of the main issues in intercultural pedagogy; identifying the possibilities and limitations of the intercultural, inclusive, and gender approaches in education; promoting the intercultural dimensions of education. Training courses and tools in intercultural competence ultimately aim to induce a transformation in attitudes and behaviors, encouraging participants to critically reassess their fundamental assumptions, worldviews, cultures, and knowledge. Teachers can delve deeply into specific topics to effectively tackle challenges in educational institutions, which must strive to become increasingly inclusive and accommodating to all students, irrespective of their ethnicity, spoken language, religion, or social status. All training activities, whether conducted in online classes or during intercultural events offline within the Didactic Center of Resources in Intercultural Education at MSU or schools and through self-training, are oriented towards cultivating multiple components/ dimensions of intercultural competences for teachers to skillfully navigate culturally diverse school environments.
