In Nordic countries, early childhood education and care (ECEC) is highly regarded for its role in supporting cognitive development, literacy, and reducing educational inequality. According to recent research conducted across Denmark, Finland, Iceland, Norway, and Sweden, the age at which children start ECEC significantly influences their literacy scores at age 15, yet it does not uniformly bridge socioeconomic gaps as hoped. The findings were published in the journal European Societies.
The study found that children entering ECEC between ages two and three generally achieve higher literacy scores compared to those who begin later, highlighting an optimal window for early education’s positive effects. In particular, Swedish children starting ECEC at this age showed the highest literacy gains among their peers. Denmark followed closely, as children attending “børnehave” (a type of childcare beginning at age three) also demonstrated strong literacy outcomes. Iceland, however, reported lower scores for children who began formal ECEC very early, as many with developmental delays enter early support programmes, potentially affecting averages.
Despite the accessibility and high quality of Nordic ECEC, the study revealed a persistent achievement gap tied to socio-economic status. While ECEC benefits all children, those from affluent families tend to experience greater educational gains. This “Matthew effect” – where the advantaged accumulate more benefit – was particularly evident in Norway. There, children from wealthier backgrounds who started ECEC early displayed significantly better literacy scores than their less affluent counterparts. Meanwhile, in Finland and Sweden, the socio-economic gap in literacy outcomes remained constant, regardless of ECEC start age.
Although ECEC can boost cognitive abilities, its role in equalising educational outcomes across socioeconomic backgrounds appears limited. The researchers suggest that families with higher socio-economic status may select ECEC programmes that better fit their needs or offer additional advantages, further extending their children’s educational edge. Additionally, social policies such as home care allowances in Finland, which enable parents to care for young children at home, may contribute to varied educational trajectories and early outcomes.
This study underscores the complexity of using early childhood education to reduce educational inequality. While ECEC programmes in Nordic countries undoubtedly benefit children’s literacy, they cannot fully compensate for family background differences. The research suggests that addressing educational disparities requires a comprehensive approach that extends beyond early childhood education, including targeted support for low-income families and additional resources throughout primary and secondary schooling.
