„Research evidence shows that there are clear benefits for children who participate in ECEC (Anm.: ECEC = Early childhood education and care) in terms of their overall development and, more specifically, their academic performance. This finding is especially valid for disadvantaged students. […] Nevertheless, data from the EU-SILC Survey and PISA 2018 reveal that children from disadvantaged families participate less in ECEC.“
