As some communities in the United States open K-12 schools, CDC offers the following considerations for ways in which schools can help protect students, teachers, administrators, and staff and slow the spread of COVID-19. Schools can determine, in collaboration with state and local health officials to the extent possible, whether and how to implement these considerations while adjusting to meet the unique needs and circumstances of the local community. Implementation should be guided by what is feasible, practical, acceptable, and tailored to the needs of each community. School-based health facilities may refer to CDC’s Guidance for U.S. Healthcare Facilities and may find it helpful to reference the Ten Ways Healthcare Systems Can Operate Effectively During the COVID-19 Pandemic. These considerations are meant to supplement—not replace—any state, local, territorial, or tribal health and safety laws, rules, and regulations with which schools must comply.
