“…While recent comparative empirical analyses (see Breen, Luijkx, Mu¨ller, & Pollak, 2009;Breen, Luijkx, Muller, & Pollak, 2010) have demonstrated that the change-resistance of inequality of educational opportunity is less pronounced than previous studies suggested (see, mainly, Shavit & Blossfeld, 1993), it is indisputable that, despite the generalised improvement of living standards and the variety of educational policies aimed at counteracting the partly social constructed ability gaps across social groups, the socioeconomic status of the family in which individuals live still exerts a substantial influence on their educational outcomes. In France, the country on which this paper focuses, while the equalising trend in educational opportunity is extremely clear (see The´lot & Vallet, 2000), although quantitatively modest (see Vallet & Selz, 2007, p. 69), individuals' social backgrounds continue pervasively to impact on the highest educational level that they reach (see Selz & Vallet, 2006), on the kind of upper secondary tracks that they choose (see Duru-Bellat, Kieffer, & Reimer, 2011;Ichou & Vallet, 2011) as well as on their chances of entering the most prestigious tertiary level educational institutions (see Albouy & Wanecq, 2003). In light of this empirical evidence, therefore, it still seems justified to consider the stratification of educational outcomes across social backgrounds as a puzzling macro-level explanandum.…”
