Education plays an essential role in preparing the children of immigrants for participation in the labour market and society. Giving these children opportunities to fully develop their potential is vital for future economic growth and social cohesion in OECD countries. But migrant students in most OECD countries tend to have lower education outcomes than their native peers. Extensive previous research has described the system level, school level and individual level factors that influence the education outcomes of migrant students. Building on such previous research, this paper looks at the ways in which "education policies" can influence these factors to help provide better educational opportunities for migrant students.

It was presented and discussed at the Second Meeting of the Group of National Experts on the Education of Migrants in Paris on 13-14 October 2008.]
