Educational inequalities in terms of systematic disadvantages and advantages in the access to education and the uptake of education – being structured by ascriptive factors such as social origin, immigrant background, gender and (dis)ability as well as their intersections – are a problem both for the individual and the society. Individuals with low educational achievement and educational attainment suffer from poor life chances on the labour market and beyond, namely a lower status attainment, lower income, higher risk of unemployment, lower political participation opportunities, lower health and finally even a lower lifetime expectancy. Educational inequality also affects societies, as higher educational equity goes along with a higher skill level in general and higher economic prosperity, but also a higher democratization level. PIONEERED addresses the social problem of educational inequalities attempting to identify pioneering policies (e.g. educational and social policies) and practices in formal and non-formal educational settings that may help to tackle inequalities and in particular disadvantages of certain vulnerable groups. The objectives of PIONEERED include a) developing an innovative methodological framework and reviewing the state-of-research, b) analysing educational policies on which inequalities and vulnerable groups are addressed by national (or regional) policies, and how polices attempt to reduce inequalities, c) analysing existing data in a new way to identify intersectional inequalities throughout educational careers and drivers of such advantages and disadvantages, and d) carrying out practice research in schools and informal educational settings and analysing the ways through which educational inequalities are tackled by different actors.
