This paper arises from the concern about school inequality. This is a topic that uses to concern European organizations. Education is one of the five key goals of the “European Strategy 2020” to achieve economic growth, to combat social inequality and build a socially and economically strong Europe. This concern is also shared by international organisations such as the OECD, the World Bank and the UNESCO which, together with the European Union have become political agents that exercise their influence on national policies.
