Preparing teachers to assist linguistically and culturally diverse students to integrate is difficult as the paradigm is not limited to students but radiates outwards. Preparation of teachers in Greece has involved the incorporation of foreign languages and courses in multiculturalism in their program of study in an effort to promote multilingualism (ML), multicultural efficacy (ME), and intercultural sensitivity (IS). In this research brief, the authors attempt to look at how we prepare teachers to meet increased challenges migration of very different populations brings to their teaching as well as how their attitude toward multilingualism, ME, and IS may be interrelated. The study's main objectives are to measure this group's level of IS, ME, and multilingual language attitudes and examine their relationship. The goal is to determine how well equipped these pre-service teachers are to deal with the linguistically and culturally diverse student populations they will be called upon to teach and what facilitates them achieving this end.
