A new study by the Economic and Social Research Institute places schools and neighbourhoods side by side to assess the leaving certificate school neighbourhood impact. The comparison asks a focused question: when family background is accounted for, which context matters more to exam results—the school a student attends or the area they live in?
ESRI study: school context outweighs neighbourhood for Leaving Certificate grades
The ESRI report finds that performance in the Leaving Certificate is more likely to be influenced by the school a student attends than by their neighbourhood. Authors Emer Smyth and Merike Darmody point to Ireland’s second-level school choice as a factor that allows more precise estimates of school and neighbourhood effects than those available in settings where students typically attend their local school.
School context emerges as a pronounced driver: even after taking social background into account, students in Deis schools recorded much lower grades than peers in socially mixed schools, while those in fee-paying schools achieved higher grades again. The study also notes that the social mix of both primary and second-level schools exerts cumulative effects on achievement, indicating that educational pathways compound over time rather than being shaped by a single stage.
Leaving Certificate School Neighbourhood Impact: DEIS disparities and fee-paying advantage
Neighbourhood characteristics do affect achievement, with lower grades observed in areas marked by higher socioeconomic disadvantage and greater neighbourhood disorder. Yet, the comparative weight tilts toward school-level context, where stratification by school type aligns with clear differences in outcomes. The report highlights a wide attainment gap tied to family background too—over 100 Leaving Certificate points between the children of graduate mothers and those whose mothers have Junior Cycle education or less.
Family variables—maternal education, social class, financial strain, and family type—each have independent effects on performance, reinforcing that context is multi-layered. Still, the leaving certificate school neighbourhood impact analysis indicates that, within those layers, the school’s social mix and type remain stronger predictors than where students live. That duality—school and area each contributing, but not equally—sharpens how policymakers might target interventions.
| Dimension | School context | Neighbourhood context |
|---|---|---|
| Relative influence on grades | More likely to influence Leaving Certificate performance | Affects achievement but with a smaller effect than schools |
| Specific markers | Deis schools: lower grades; fee-paying schools: higher grades | Disadvantage and neighbourhood disorder linked to lower grades |
| Adjustment for background | Differences persist even taking social background into account | Effects considered alongside family and school factors |
| Measurement advantage | Irish school choice enables clearer separation of effects | Less isolatable where local schools are the default |
| Cumulative effects | Primary and second-level school social mix both affect results | Influence present but framed within family and school contexts |
| Policy implication | Current Deis supports do not close the outcome gap | Neighbourhood disadvantage noted; school-focused supports emphasized |
DEIS supports and the proposed Deis plus: what the data imply
The study concludes that current supports for schools serving disadvantaged communities, provided through the Deis programme, do not appear sufficient to bridge outcome gaps for this cohort. That finding is reinforced by the persistence of lower grades in Deis schools even after accounting for social background, contrasted with higher grades in fee-paying schools. It places the emphasis on school-level interventions as the lever with the greatest potential to shift results.
The authors argue for additional supports for schools in the most deprived communities, with the findings set to underpin a “Deis plus” designation. The reasoning is straightforward: if school context carries more weight than neighbourhood context, then incremental resources targeted at school environments—staffing, supports, or other measures—not only align with the evidence but also address where the data show the largest effect.
Family background remains a powerful force across both contexts. Maternal education, social class, financial strain, and family type each shape outcomes independently, and the over-100-point gap tied to maternal education underscores that the academic playing field is uneven before a student enters any classroom. Yet, the comparative analysis suggests that when policy must choose where to intensify support, school-level action offers the clearer route to lifting grades.
The finding is direct: schools matter more than neighbourhoods for Leaving Certificate performance, though both contribute. The next test will be whether a Deis plus designation, once in place, narrows the gaps observed between Deis, socially mixed, and fee-paying schools. If the strongest driver—school context—receives stronger support, the comparison suggests the achievement divide should begin to shrink.
