Tracking (education) Tracking has been shown to produce less academic achievement for low-ability students, and higher academic achievement for high-ability students; de-tracking would increase the achievement of the worst students and harm the achievement of the best students.[46] Critics say that not challenging all students with the most advanced curriculum results in overall low student educational achievement,[47] and that students in low tracks do not learn as much as their peers in higher tracks, e.g., advanced mathematics.[48]
