How do educational inequalities develop? The role of socioeconomic status, cognitive ability, home environment, and self-efficacy along the educational path

Abstract

In Western countries, children's education is strongly influenced by their social background, which cannot be fully explained by individual differences in cognitive ability between social classes. It is still an open question how, to what extent and at what point along the educational path individual and family factors shape children's educational success. In the present study, twins (N = 6174) clustered in three age cohorts (11, 17 and 23 years) were examined using multilevel analyses to test if parental socioeconomic status (SES) and children's cognitive ability, as well as family's quality of home environment and children's self-efficacy can explain the development of educational inequalities captured via school track recommendations and university attendance. Results showed educational inequalities at each critical point along the entire path of education. With increasing parental SES, individual cognitive abilities mattered significantly less, so that children from high parental SES families often received a recommendation to attend upper secondary education even with low cognitive abilities. In contrast, the association between cognitive abilities and university attendance increased with increasing parental SES in the older age cohort, whereby individuals with high cognitive abilities but low parental SES rarely attended university. Furthermore, for school track recommendations, with increasing children's self-efficacy and better home environment the educational recommendation improved, while home environment amplified the effect of SES on the development of educational inequalities. These results suggest a waste of academic potential of low SES children. Subsequent studies should examine further constructs that could contribute to the development of educational inequalities.
