„OECD data show large socio-economic gaps in maths scores for 15-year-olds. […] This is, at least partly, a hangover from ECEC as, in some countries, the socio-economic gaps in early years participation are particularly stark. Children from low-income families are less likely to attend ECEC programmes. Even when they do, the quality of services they receive is often inferior. This perpetuates a cycle of disadvantage that is hard and costly to break.“
