Students in over 150 countries experienced school closures throughout the COVID-19 pandemic. In the years following, a growing body of literature seeks to estimate the impacts of these education disruptions on a diverse set of outcomes, including student learning. This article adds to this research by examining causal evidence through a difference-in-differences framework (DID). Results suggest that school closures led to learning losses in math for high school seniors in public schools in the Federal District (DF) in Brazil. And while all racial groups experienced learning loss, White and Asian students experienced the most significant losses in 2020. We find no evidence of learning recovery from 2020 to 2021 for any racial groups, suggesting that learning losses persisted into school reopening. We do find, however, possible signs of recovery for female senior students compared to male students. Nevertheless, male and female performance differences are still prominent when analyzing data from 2016 to 2021. The utilization of critical policy analysis and the effectively maintained inequality frameworks can offer insights into significant learning disparities experienced by students.
