Since early in the COVID-19 pandemic, parents, teachers, and school administrators have faced difficult questions regarding when and how to safely reopen for in-person learning.

A new study in The Journal of School Health joins a growing body of evidence that, with appropriate measures, there are ways for schools to safely reopen.
