Preliminary Research

We envision the COVID-19 School Data Hub as a resource to help generate knowledge about how school learning models during the pandemic may have shaped a variety of outcomes for both children (including both academic and health outcomes) and adults. These preliminary white papers introduce the CSDH project and provide an example of how to explore and learn from the learning model data.

Correlates of January 2022 COVID-19 Schooling Disruptions

An examination of January 2022 school closures (based on Burbio data) by school closure information from 2020-21 and district demographic information. The data indicate that 2022 school closures are disproportionately affecting districts that had less in-person learning and more virtual learning in the prior school year.

Pandemic Schooling Mode and Student Test Scores: Evidence from U.S. States

This NBER working paper estimates the impact of district-level schooling mode (in-person versus hybrid or distance learning) on test scores. We combine Spring 2021 state standardized test score data with comprehensive data on schooling in the 2020-21 school year across 12 states. We find that pass rates declined compared to prior years and that these declines were larger in districts with less in-person instruction. Passing rates in math declined by 14.2 percentage points on average; we estimate this decline was 10.1 percentage points smaller for districts fully in-person. Changes in English language arts scores were smaller, but were significantly larger in districts with larger populations of students who are Black, Hispanic or eligible for free and reduced price lunch.
