Research has shown that attendance at early childhood education and care programmes can have a significant impact on children’s cognitive, social and emotional development, and on their performance in school – and in life – later on. There is evidence from both randomised controlled trials and observational studies that early childhood education and care has the potential to improve the life chances of children from disadvantaged families; yet results from PISA show that advantaged children are more likely to attend, and to attend for longer periods of time. Failing to tackle this situation could mean that early childhood education and care continue to exacerbate rather than mitigate inequities in education and in society.
Some evidence suggests that peers in early childhood education and care influence children’s language and socio-emotional development. It is thus urgent for policy makers to identify the extent to which disadvantaged children are clustered together in early childhood education and care programmes, and whether and where centres with substantial numbers of disadvantaged children are of lower quality than those attended by more affluent children. In most countries, socio-economically disadvantaged children are the least likely to attend high-quality programmes.
