As the COVID-19 pandemic wears on and the nation’s schools strive to find ways to open for in-person learning, a critical element of that work is understanding what it takes to make—and keep—the physical school buildings safe and healthy for staff and students alike. Join Dr. Emily Oster (economist at Brown University) and Dr. Joseph Allen (environmental health researcher and director of the Healthy Buildings Program at Harvard University) for a look at what the National COVID-19 School Response Dashboard tells us about what is going on in schools right now as it relates to COVID-19 spread, mitigation strategies, and opening with the additional context of the actual physical requirements of the schools: healthy buildings, healthy classrooms, healthy policies, healthy schedules, and healthy activities.
