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...

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

This paper evaluates how sharing a kindergarten classroom with low-achieving repeaters affects the long-term educational performance of regular first-time kindergarten students. Exploiting random assignment of teachers and students to classes in Project STAR, I document three sets of causal...

This paper aims to highlight the importance of considering endogenous peer effects, as defined by Manski (1993), in order to identify gender composition effect on education outcome appropriately. Using Manski (1993) linear-in-means model, this paper illustrates that the gender composition effect...

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...

We report results from a large-scale, pre-registered randomized field experiment in 159 Norwegian schools over four years. The intervention includes students aged 7-9 and consists of pulling students from their regular mathematics classes into small, homogenous groups for mathematics instruction...

This paper examines the efficacy of class-size reductions as a strategy to improve pupils' learning outcomes in India. It uses a credible identification strategy to address the endogeneity of class-size, by relating the difference in a student's achievement score across subjects to the...

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,...

In recent years, many countries have experienced a significant expansion of higher education enrolment. There is a particular interest among policy makers for further growth in STEM subjects, which could lead to larger classes in these fields. This study estimates the effect of class size on...

The paper examines the impact of class size on postgraduate grades using administrative data from one of the largest Schools of a Russell Group University in the UK. As well as estimating Fixed Effects models on the population of postgraduate candidates in the School, we exploit a policy change...
