Using administrative data from Maryland, North Carolina, and a large urban school district, we find that the impact of absences on test scores was modestly (about 5 to 20%) smaller in 2022-23 than in 2018-19 but still practically and statistically significant. Consistent with prior research, these harmful effects of absences are approximately linear and exhibit little heterogeneity across race and gender pre-Covid. In Maryland, the impact of tenth-grade absences on high-school graduation and 2-year college enrollment was much (about 40%) smaller after the pandemic than before, but the impact of absences on any (2- or 4-year) college enrollment increased slightly. Post-Covid reductions in the harmful effects were larger for white students on test scores and larger for Black students on graduation.}, keywords={chronic absence;attendance;learning loss}, }
