The efficiency of schools can be defined and measured as the ratio between the outputs produced (for example, achievement and competences) and the inputs utilized (human and technical resources). Technology holds the promise of increasing the efficiency of schools' operations, although empirical evidence on this is still scarce. This paper explores whether the ICT availability and use in 2757 schools from 10 Latin American countries are associated with higher efficiency, relying on PISA 2018. A method based on a double-bootstrap Data Envelop-ment Analysis (DEA) is employed. The results highlight that the availability of ICT is positively correlated with higher school efficiency. This evidence is relevant for policy implications in setting the post-COVID priorities for educational systems in the region.
