Simulating the Potential Impacts of COVID-19 School Closures on Schooling and Learning Outcomes: A Set of Global Estimates

 This paper presents the results of simulations considering different lengths of school closure (3, 5, and 7 months) and different levels of mitigation effectiveness (mostly remote learning), resulting in an optimistic, intermediate, and pessimistic global scenario. Using data on 157 countries, we find that both the global level of schooling as well as learning will fall. COVID-19 could result in a loss of between 0.3 and 0.9 years of schooling adjusted for quality, bringing down the effective years of basic schooling that students achieve during their lifetime from 7.9 years to between 7.0 and 7.6 years. Close to 7 million students from primary up to secondary education could drop out due to the income shock of the pandemic alone. Without compensatory actions when children return to schools, students from the current cohort could, on average, face a reduction of $355, $872, and $1,408 in yearly earnings depending on the scenario. In present value terms, this amounts to between $6,472 and $25,680 dollars in lost earnings over a typical student’s lifetime. As closures continue in low- and middle-income countries, the pessimistic scenario is more likely. Exclusion and inequality will likely be exacerbated if already marginalized and vulnerable groups, like girls, ethnic minorities, and persons with disabilities, are more adversely affected by the school closures. Globally, a school shutdown of 5 months could generate learning losses that have a present value of $10 trillion. By this measure, the world could stand to lose as much as 16% of the investments that governments make in this cohort of students’ basic education.
