As online classrooms become more common, schools and school districts should consider how use of them might impact school safety, security, emergency management, and preparedness planning and how online classrooms may be affected by various hazards and threats. This fact sheet provides emergency management planning considerations for online classrooms from an all settings, all times perspective, which includes schools and programs that are fully online; it also highlights the importance of considering online classrooms in EOP annexes, such as the Continuity of Operations (COOP) Annex and the Cyber Annex (see ED593772). A list of resources is also provided.
