This study examined the experiences of 15 refugee school teachers in Athens, focusing on their strategies for working with culturally diverse adult students. Through semi-structured interviews, the research investigated the evaluation of intercultural education that is imparted to adult refugees, the challenges in the program’s implementation for adult refugees, the importance and the necessity of intercultural competence for instructors when working within refugee structures, and the possible ways of influencing the ethnic diversity of adult refugee immigrants that affect teachers’ perspectives regarding their education and social integration. The findings reveal a mix of progress and challenges in cultural education, exacerbated by the global financial crisis and infrastructure deficiencies. Intercultural competence emerges as vital for fostering inclusive learning environments, while embracing ethnic diversity shifts the focus from assimilation to celebration. Success indicators include cultivating a collective consciousness, promoting interaction between cultures, fostering empathy, and providing adequate resources. These insights offer valuable implications for enhancing refugee education and integration efforts in Athens and beyond.
