Opportunities for social mobility are generated by education systems designed to alleviate the effects of social origin by providing equality of opportunities and resources. The persistence of the strong association between socioeconomic status (SES) and child's educational achievement and attainment suggests that social origin continues to play an integral role in the educational outcomes of successive generations of Australians. Sociologists draw on a range of theoretical perspectives to explain this association including Bourdieu's cultural and social capital theories. Using data collected by the Longitudinal Survey of Australian Youth 2009 (LSAY09) project, I examine the associations between student SES, school SES and two outcome variables: Programme for International Student Assessment (PISA) score and university enrolment. The results indicate that low SES students attending high SES schools perform better on PISA tests than low SES students attending low SES schools. After controlling for PISA score, low SES students were less likely than their high SES peers to enrol at university. Furthermore, students attending low SES schools were less likely than their peers attending high SES schools to enrol at university, net of their individual SES and their PISA scores.
