This study examines the gendered effects of early and sustained exposure to high-performing peers on female educational trajectories. Exploiting random allocation to classrooms within middle schools, we measure the effect of male and female high performers on girls' high school placement...

This paper designs and implements a field experiment that provides students from less advantaged backgrounds with individualized feedback on academic performance during the transition from middle to high school. The intervention reduces the gap between expected and actual performance, as well as...

We design and implement a field experiment that provides students from less advantaged backgrounds with individualized feedback on academic performance during the transition from middle to high school. The intervention reduces the gap between expected and actual performance, as well as shrinks...
