Issues of educational equity and opportunity cannot be understood without regard to special education, as a key response to disabilities, disadvantages, and difficulties. Likewise, globalization cannot be understood without regard to cross-border migration and minority group status in society. Illuminating the nexus of these, research into disproportionality in special education, defined as the over- or under-representation of particular ethnic groups in such programs, shows that this, too, has become a global phenomenon. Comparing Canada, Germany, New Zealand and the USA, this article explores international trends in migration and discusses the globalization of ethnic group disproportionality--as a primary indicator of inequity in education. We conclude by questioning the functions of special education in an era of globalization and identifying the challenges ahead that these findings indicate. (Contains 5 tables.)
