“…School systems which are highly differentiated, that is, track students from an early age into different streams and levels, tend to produce more gender inequality than countries with less differentiated systems (Bradley and Charles 2004;Charles 2011;Webbink 2009, 2011;Van Langen, Rekers-Mombarg, and Dekkers 2008;Wöβmann 2009). Other research findings also show that in countries where pupils are given more freedom to choose between alternative trajectories, patterns of educational choice are found to be more gendered (Abbiss 2009;Van de Werfhorst, Sullivan, and Cheung 2003;Van Langen and Dekkers 2005;Van Langen, Rekers-Mombarg, and Dekkers 2008; for a more detailed description of these findings, see also Yazilitas et al 2013).…”
