Using data from three waves of PIRLS, this paper examines the effect of teacher quality on fourth-grade students' literacy test scores by exploiting variations induced by reforms in teachers' selection and/or reward schemes. We construct an original data set of relevant reforms taking place at...

International surveys of learning achievement and functional literacy are increasingly common. We consider two aspects of the robustness of their results. First, we compare results from four surveys: TIMSS, PISA, PIRLS and IALS. This contrasts with the standard approach which is to analyse a...
