Our research examines Greek special and general education teachers' fears toward disability and their impact on teaching in inclusive classrooms. We interviewed 12 teachers from the region of Attica (Athens) and documented attitudes and beliefs toward disability, with the goal of identifying teachers' personal sources of resistance to inclusion. Medical paradigm of understanding disability and the absence of inclusive school culture are some of the results that revealed teachers’ sources of resisting to inclusive changes and the way these affect their teaching. Based on these findings, we discuss a two-pronged process that shifts the existing culture of understanding disability and welcomes diversity in schools.
