An ad hoc committee will provide states and districts with guidance about whether and how to safely reopen schools in the 2020-2021 school year. The committee will write a short letter report drawing on evidence from epidemiology, public health, and the social and behavioral sciences. The report will provide guidance on the health-related issues for safely reopening schools and the practices that should be implemented in order to maintain and monitor the health of staff and students. The report will address questions that have emerged from the planning efforts of state and district officials which are currently underway.
