Back-to-school 2020 didn’t go as smoothly as hoped. Many districts that were slated to offer in-person learning abruptly changed to their reopening plans only weeks before the start of the year, and many of those that did reopen for in-person learning were forced to close for weeks at a time as Covid rates increased.

Dr. Joseph Allen, an associate professor of exposure assessment science at Harvard University, discusses the CDC's recently updated reopening guidance for schools, the importance of ventilation as a Covid mitigation strategy, and solutions for America's "sick" school buildings on this episode of The Report Card with Nat Malkus.
