How Delaware Schools Handle Snow Days

Superintendents consult with road crews, transportation supervisors, and the National Weather Service before announcing closures, two-hour delays, or remote-learning days. In Delaware it is common for districts in the same metro area to make different calls based on local conditions. Closures are communicated through district websites, automated phone calls, local TV and radio stations, and increasingly through social media and parent alert apps.
