„No education and training system manages to decouple performance from socioeconomic status. Young people from disadvantaged socio-economic backgrounds are almost six times more likely to underachieve at age 15 than those from advantaged socioeconomic backgrounds, suggesting a strong intergenerational transmission of educational disadvantage. Such inequities do not emerge at age 15 and do not stop there.“
