This paper is concerned with identifying whether selective high schools may have an effect on students’ post-secondary trajectories and labor market prospects. It uses data from Tunisia, a country in which unemployment rates for post-secondary graduates are higher than for non-graduates, particularly for women—although there is significant variation across types of diplomas and fields of study. Our main finding is that admission to an elite high school raises students’ probability to eventually get assigned to a university program associated with a lower post-graduation unemployment rate. This is particularly true for women. Focusing then on students who would have applied to post-secondary programs regardless of admission to an elite high school, we show that this effect is the result of an increase in the competitiveness of their applications rather than of a change in their probability to apply to programs lower post-graduation unemployment rate.
