„Gaps in participation and quality in ECEC are a likely factor contributing to growing differences in academic performance between the most socio-economically advantaged and disadvantaged children at ages 10 and 15. Children from disadvantaged backgrounds may start ECEC later or receive ECEC of a lower quality compared to advantaged peers, perpetuating disadvantages that come from the home and neighbourhood environments and can persist throughout their educational journey.“
