With an aim to investigate inclusion across borders, quantitative and qualitative data were examined that came from 18 countries: Australia, Brazil, Canada, Cyprus, Finland, France, Iceland, India, Ireland, the Netherlands, Norway, Portugal, Slovenia, South Africa, Spain, Sweden, the UK, and the USA. Four themes emerged in this study: (1) concerns with student outcomes in inclusive settings; (2) teachers' beliefs and the ways they relate to their practices; (3) inclusive schools philosophies and practices; and (4) the intersection of inclusion and exclusion. Although international policies, knowledge, and understanding about inclusion and inclusive practices continue to advance throughout the world, there are manifestations of provincialism and discrimination predominantly marked by ethnicity, socio-economic status, and ability. While a reality for some students, inclusion remains an aspiration for too many. (Contains 1 table.)
