Does Ability Tracking Exacerbate the Role of Family Background for Student's Test Scores?

This study investigates whether ability tracking exacerbates the role of parental background for students educational test scores. Using microdata from different educational studies, PISA, PIRLS and TIMSS, this paper exploits the cross-country variation in tracking policies to identify the effect of tracking. Controlling for unobserved country level variables using difference-in-differences, I find that family background is more important in early tracking countries but that the importance of family background does not increase after actual tracking has taken place. This suggests that tracking does not augment the role of family background for students' test scores. Factors other than tracking are more likely to be responsible for the fact that family background is more important in early tracking countries. This result runs contrary to the findings of the current literature. In support of my findings, I show that the results of the current literature are not robust to slight changes in specification.
