Both national and international studies of education often show that the performance of immigrant students is substantially lower than that of non-immigrant students. This article investigates the contribution of socio-economic, sociocultural and school factors to the relative performance of first- and second-generation immigrant students in twenty countries using data from the OECD's 2000 Program for International Student Assessment. In most countries, socio-economic factors substantially account for the weaker performance of immigrant students, whereas sociocultural factors contribute little and school factors are important in only a limited number of instances. Altogether, these factors account for the bulk of the difference in achievement between immigrant and non-immigrant students in almost all the countries examined.
