Does Tracking Increase Inequality by Reinforcing Relative Age effects in Education?

There is empirical evidence that relative age differences in class leads to inequality between older students and younger students because relatively older students tend to have higher test scores and are less likely to be retained. This thesis uses data from TIMSS in a difference-in-difference approach in order to investigate whether early tracking increases the inequality between younger and older students that arises due to differences in relative age. The main findings suggest that early tracking tends to decrease the inequality between older and younger students that arises due to differences in relative age.
