“…Although inequality in completing secondary education decreased during the period of educational expansion, social inequality in post-secondary decisions increased (Mayer, Müller, & Pollak, 2007). Given the same level of achievement, students with Abitur from a higher social background more often access university directly, whereas students from the middle and lower classes more often opt for the less risky strategy of vocational training first and studies afterwards, or they even decide against higher education studies despite their eligibility (Becker & Hecken, 2009;Hillmert & Jacob, 2003;Mayer et al, 2007;Müller & Pollak, 2004;Reimer & Pollak, 2010). Those who have decided to take up higher education studies differ in their educational biography depending on their social origins.…”
