Using a comprehensive administrative database we exploit independent quasi-experimental methods to estimate the effect of class size on student achievement in Norway. The first method is based on a maximum class size rule in the spirit Angrist and Lavy (1999). The second method exploits...

This paper exploits discontinuous grade mixing rules in Norwegian junior high schools to estimate how classroom grade composition affects pupil achievement. Pupils in mixed grade classrooms are found to outperform pupils in single grade classrooms on high stake central exit tests and teacher set...
