Educational inequality remains a persistent barrier to social mobility. In England, the unequal distribution of educational success and achievement across different social groups remains a critical issue (Sutton Trust, 2021). Inequalities often emerge early in childhood and can influence an individual's life chances and social mobility (Heckman, 2006). In Norway, despite an egalitarian ethos, educational outcomes are influenced by socioeconomic background. While universal childcare ensures 93% participation, the primary equity challenge is the integration of immigrant students, who comprise 21% of the population (IMDi, 2025). Data shows that immigrant-background students achieve lower average grades than native peers. This suggests a "Matthew effect" where children from majority backgrounds derive greater linguistic benefits from early education than minority-language peers (Bakken, 2024). Consequently, while "second-generation" students are often highly ambitious, they face higher dropout rates and longer completion times in higher education than the general population (Statistics Norway, 2024). Although early childhood education (ECE) interventions/programs are widely recognized as a primary tool for fostering equity, longitudinal evidence regarding its impact on long-term outcomes—specifically post-16 attainment—remains critical for future policy design. This study evaluates the long-term effectiveness of two major ECE interventions: England’s Sure Start Program and Norway’s Free Core Time in Kindergarten Initiative. The Sure Start (est. 1998) initiative in England targeted early inequalities in deprived communities by providing integrated health and development services to close the achievement gap. Similarly, Norway’s Free Core Time (Gratis kjernetid) (est. 1998), originally provided 20 free weekly hours of kindergarten for children aged 2–5 from low-income families in certain areas (Drange and Telle, 2015). While Sure Start focused on broad community support, the Norwegian scheme specifically aims to improve school preparedness and language proficiency among minority groups, facilitating socialization into national norms and values. This study focuses on the specific cohorts prioritized by each state as the primary "equity targets": socioeconomically disadvantaged students in England (measured by enrolment in Free School Meals) and socioeconomically disadvantaged migrant-background students in Norway. This allows for a critical evaluation of whether targeted ECE can successfully mitigate the dominant drivers of inequality in different welfare contexts—addressing the class-based stratification prevalent in England and the linguistic and cultural integration challenges in Norway. The study offers critical insights into the mechanisms through which ECE interventions can reduce intersectional disadvantages. The findings aim to inform international policy development, offering a robust evaluation of how early-years reform shapes educational trajectories in the long term.
