We examine the relationship between absenteeism and achievement since the onset of COVID-19. Applying first-differences models to North Carolina administrative data, we estimate that each absence was associated with a 0.0032 standard deviation (SD) decline in math achievement in 2022-23. As students averaged 3.3 more absences in 2022-23 than…

We estimate the effects of accountability-driven school closure in New York City on students who attended middle schools that were closed at the time of closure and students who would have likely attended a closed middle school had it remained open. We find that students who would have entered the closed school had it not closed attended schools…

I document sizable confounding track effects, and show that traditional tests for the existence of teacher effects are likely biased. After accounting for these biases, high-school algebra and English…
