The role of language tests in immigration policy has attracted significant attention in recent years as the disruptive effects of globalisation are felt. Much of the research has focused on the situation in Europe, where societies that were traditionally not countries of immigration now have significant and increasing immigrant communities. Less attention has been paid to countries of immigration such as Australia, Canada, New Zealand, and the United States, which have sometimes encouraged immigration and have found it easier to embrace various forms of multiculturalism, despite some inevitable tensions. This chapter provides an account of the complex and rapidly changing role that language test scores have played in immigration policies favouring highly skilled migrants in Australia, and draws on Foucault’s discussion of the function of examinations to explore the impact of these changes on the lives of individuals subjected to the policies.
