Abstract

Research has consistently shown that family socioeconomic status (SES) is strongly associated with student achievement, but relatively little is known about how national contexts shape the strength of that relationship across countries. This study examines whether income inequality moderates the association between family SES and student learning using cross-national data and multilevel modeling. Using data from the Program for International Student Assessment (PISA), it examines how differences in national income inequality relate to variation in the relationship between family social status, parental education, and student learning.
The results show that the association between SES and learning varies across countries in ways that are not strictly linear. In countries with moderate levels of income inequality, socioeconomic differences in achievement tend to be smaller, while both more unequal and more equal countries show stronger links between family background and student outcomes. Interestingly, this pattern suggests that national inequality may shape the opportunity structures through which families translate resources into educational advantage, challenging the assumption that lower inequality necessarily produces more meritocratic educational systems. This research contributes to a sociological understanding about how structural context shapes educational stratification across nations.
The analyses presented here examine the PISA 2000 cohort to establish the theoretical and modeling framework for this exploratory study; replication using more recent cross-national data (to be completed before ASA 2026) is currently being conducted to assess whether this pattern holds up over time.
