Raising schooling quality in low-income countries is a pressing challenge. Substantial research has considered the impact of cutting class sizes on skills acquisition. Considerably less attention has been given to the extent to which peer effects, which refer to class composition, also may...

This paper studies the effect of multigrading-mixing children of different ages in the same classroom-on students' short- versus long-term academic achievement in Italy. We cope with the endogeneity of multigrading (and class size) through an instrumental variable identification strategy based...

This study estimates teacher value-added (TVA) for language arts and mathematics test scores of students in public primary schools to investigate the empirical relationship between testscore TVA and observable traits and promotions of teachers. Our empirical strategy employs Chetty, Friedman,...

I estimate the effect of class size on scholastic achievement using that schools are only in session during the school year and out of session during the summer. This seasonal feature of the schooling system makes it possible to control for unobservable pupil characteristics affecting both the...

We use administrative panel data on about a quarter of a million students in the German state of Hesse to estimate the causal effect of class size on school tracking outcomes after elementary school. Our identification strategy relies on the quasi-random assignment of students to different class...

We estimate the nonlinear impact of class size on student achievement by exploiting regulations that cap class size at 20 pupils per class in kindergarten. Using student-level information from a previously unexploited large-scale census survey of kindergarten students, this study provides clear...
