„Higher-performing students reported that their family regularly (‚about once or twice a week‘ or ‚every day or almost every day‘) eats the main meal together, spends time just talking with them, or asks them what they did in school that day. These students scored 16 to 28 points higher in mathematics than students who reported that their family does not do those things regularly, on average across OECD countries and after accounting for students’ and schools’ socio-economic profile.“
