Implication

Longitudinal observational study reveals mild but stable school and class segregation across grade levels, indicating that residential patterns and academic tracking drive student separation.

Key Points

To assess patterns and long-term trends of school- and class-level segregation by student achievement, immigrant status, and socioeconomic background across grades 1 through 12.
Evaluated national administrative data encompassing approximately 5,000 public schools across all 278 mainland Portuguese municipalities over a 10-year span (2006/07–2016/17).
Calculated density-corrected dissimilarity indices to estimate both between-school segregation within municipalities and within-school class segregation across grade levels.
School-level segregation remained mild and stable over the decade, peaking in primary education due to localized residential demographics and narrow school catchment areas.
Class-level segregation within schools was similarly mild and stable overall but became substantially higher in upper-secondary education, particularly for low-achieving students as a result of academic tracking.
