| | Abstract:
The literature has traditionally measured underachievement as the difference between capacity test scores, such as IQ, on the one hand, and achievement test scores or school grades on the other. This paper questions the current empirical practice and suggests an innovative approach to separate persistent underachievement, time-varying underachievement, pupil heterogeneity and random noise. Drawing on Flemish data from kindergarten until grade two we show that overall underachievement amounts to around 46% and is mainly driven by permanent factors, making it likely to persist over time. At first sight, we observe no effect of class size on underachievement. However, once we allow marginal effects to vary over class sizes, larger classes seem to reduce underachievement below a class size of 19 students, while the opposite effect occurs above this threshold. Moreover, IQ and gender may play a significant role when measuring the effect of class size on underachievement. Larger classes may reduce underachievement for gifted and female pupils, while this effect occurs solely below a class size of 17 pupils for the ungifted and male pupils. Above this threshold, larger classes are likely to exacerbate underachievement. The results further indicate that gifted and male pupils are most susceptible to underachievement. We argue that a class size of 19 pupils is most effective in combatting academic underachievement.
