Is a tree known by its fruits? The eect of the Cito-test on intergenerational educational mobility

This thesis looks at the eect of the introduction of the cito-test on intergenerational educational mobility. Initiated by Professor A. De Groot, the cito-test was introduced in 1969. De Groot wanted to make the advice for a child to which level of secondary education it should go more just by having an objective test besides the assessment of a teacher. In this study, a fuzzy Regression discontinuity is exploited, trying to nd a causal eect of the introduction of the cito-test on intergenerational educational mobility. The results show that the cohort just after the introduction of the test had a signicant lower mobility than the cohort just before the introduction, indicating that the cito-test caused a drop in intergenerational educational mobility.
