To overcome endogeneity issues due to unobserved ability, we apply an IV approach exploiting variation in age-at-arrival and the linguistic distance between origin and destination country languages. Using four PISA waves, we find a strong influence of reading performance on math performance, highlighting the importance of early language support for immigrants for their educational career. %K age-at-arrival %K immigrants %K linguistic distance %K math performance %K language %K instrumental variable
