Inequalities in children's skills on primary school entry in Ireland and Scotland: do home learning environment and early childhood childcare explain these differences?

This article draws on the Growing Up in Ireland study and the Scottish sample of the Millennium Cohort Study to explore the factors influencing inequalities in children's cognitive skills on entry to primary education. It adopts a multidimensional comparative approach, which directly compares the effects of parental education and household income on several cognitive outcomes (vocabulary, language, reading and numbers) among five-year-old children and examines the extent to which inequalities in these outcomes are mediated by the home learning environment (HLE) and early childhood education (ECE). Home learning environment plays a stronger role in explaining actual vocabulary differences in Ireland while it plays a stronger role in school readiness (teacher-assessed skills) in Scotland. In both countries, use of centre-based care at 9 months and 3 years was markedly higher among the top income quintile. Centre-based care is found to play a mediating role in school readiness in Scotland. Nonetheless, the findings point to important direct effects of family background even when HLE and childcare are taken into account. The analyses point to differences in the trajectory of early skill development in the two countries, with the impact of early skill development being more marked in Scotland than Ireland. Comparative analyses of this kind thus yield important insights for policy development by highlighting potential domains (such as childcare) or timing (preschool or within-school) for intervention.
