Neoliberal reforms in education led to the creation of elite schools which resulted in educational inequality that later often channels into economic and social inequalities. This research aims to deepen the understanding of the impact of elite secondary education on inequality in a post-Soviet context. The study empirically examines the gain in academic performance achieved by graduates of better-funded, better-quality, elite public secondary schools in Kazakhstan during their studies at a university, with a sequential mixed-method approach. Our quantitative analysis documents that they indeed perform better than their peers who have studied at mainstream public schools. The qualitative analysis underscores that elite schools in Kazakhstan, with superior infrastructure and academic standards, prioritize soft skill development, yet exacerbate educational inequality by limiting access to students without resources or means to relocate. This work has important policy implications most crucial of which is the efficiency of public funding policy that anchors educational inequalities. Our research highlights how neoliberal reforms in Kazakhstan have exacerbated educational inequality through the emergence of state-sponsored elite and private schools, echoing broader concerns about the negative impact of education marketization on equity in post-socialist contexts.
