Using a large administrative data set from Chile, we find that, on average, boys perform better than girls in mathematics. In this paper, we document several features of their relative performance. First, we note that the gender gap appears to increase with age (it doubles between fourth grade...

We establish the presence of a gender gap in mathematics across many low- and middle-income countries using detailed, comparable test score data. Examining micro level data on school performance linked to household demographics we note that first, the gender gap appears to increase with age....
