In Tennessee public high schools, COVID-19–era disruption led to substantial and uneven declines in learning, measured using ACT composite scores. The study reports that the statewide average dropped from 20.2 in 2019 to 19.1 in 2021, then recovered only to 19.3 by 2024–2025.

The research also examines how recovery related to school characteristics while Tennessee received additional federal and state funding during the same period. Using statistical models, the authors find that schools with higher pre-pandemic ACT scores and higher shares of economically disadvantaged students were more likely to experience greater learning loss and less complete recovery.
