“…Accordingly, studies show that students with lower academic abilities and disadvantageous socioeconomic backgrounds are placed in lower tracks, which negatively affect academic performance (Becker, Lüdtke, Trautwein, Köller, & Baumert, ; Guill, Lüdtke, & Köller, ; Gustafsson, ; Korthals & Dronkers, ; Retelsdorf, Becker, Köller, & Möller, ). Using the same sample as this study, a study in Flanders also found that lower track placement negatively affects academic performance (Dockx et al ., ). Therefore, increased inequality in academic performance is explained by the separation of student across lower and higher tracks, with lower track allocation negatively affecting academic performance.…”
