“…Nonetheless, the possibility that school tracking may affect educational inequality must also be considered (van de Werfhorst & Mijs, 2010). Some authors argue that tracking increases inequality among students (Gamoran & Mare, 1989;Lucas, 1999Lucas, , 2001Oakes, 1985) not only in terms of dispersion of achievement (Galindo-Rueda & Vignoles, 2005;Hanushek & Woessmann, 2006;Manning & Pischke, 2006) but also in terms of inequality of opportunities-namely, the strength of the influence of family background on student outcomes. These studies usually quantify the extent to which economic, cultural, and social resources in the home environment affect student achievement across educational systems characterized by different institutional arrangements (Bol & van de Werfhorst, 2013;Brunello & Checchi, 2007;Jackson, 2013).…”
