Recent evidence suggests a positive effect of the quantity of instruction on student achievement. In this paper, I focus on the interaction between the quantity and the quality of instruction. Using international TIMSS data, I exploit within-student between-subject variation. I find that on...

Using data from TIMSS 2015, an international large-scale assessment of student skills, I investigate the effect of teacher characteristics on students' science achievement.
