„Appropriate funding is essential for the good performance of education systems: although increasing resources does not, on its own, significantly improve education systems’ performance, the level of spending on education does affect educational outcomes, in particular of children and young people from disadvantaged backgrounds as it can reduce socio-economic differences between pupils from poorer and more affluent families.“
