Note: Sample schools refer to schools included in this paper. All schools refer to the universe of Chilean schools that administer the SIMCE standardized national test. The socioeconomic status of the school for the analysis at the school level was adopted as defined in the public databases of SIMCE. The Education Quality Assurance Agency, responsible for the SIMCE, classifies schools into socioeconomic categories based on four variables: mothers’ years of education, fathers’ years of education, monthly income reported by parents, and a vulnerability index developed by the Ministry of Education
