International research has consistently found that the socioeconomic segregation of schools may worsen inequalities in schooling outcomes through the socioeconomic compositional effect. This study examines whether the socioeconomic compositional effect varies between developed countries and potential mechanisms by which national schooling systems…

Increased social and academic segregation are known side effects of school choice policies in market-driven environments that facilitate competition amongst schools. Aiming at complementing foundational knowledge in quantifying segregation, this study first defines school markets (i.e., geographical context) based on student transitions from…

School socio-economic compositional (SEC) effects have been influential in educational research predicting a range of outcomes and influencing public policy. However, some recent studies have challenged the veracity of SEC effects when applying residualised-change and fixed effects models and simulating potential measurement errors in hierarchical…

It is well known that socio-economic status (SES) at both the student and school level is associated with educational outcomes. Students from higher social backgrounds, on average, have greater educational outcomes than their less privileged peers. Also, a student that attends a school that enrols students from primarily high social backgrounds…

Background/Context: It is well established in the research literature that socioeconomically disadvantaged students and schools do less well on standardized measures of academic achievement compared with their more advantaged peers. Although studies in numerous countries have shown that the socioeconomic profile of a school is strongly correlated…
