Yes, Michigan public schools are legally required to make up days lost to inclement weather. The Michigan Department of Education (MDE) mandates a minimum of 180 instructional days per school year. When a district cancels school due to snow or other emergencies, it must recover the lost time through an approved plan.
The specific approach is determined by the local school board, but the district must submit its make-up plan to the MDE for approval. This ensures compliance with the 180-day requirement while allowing flexibility for local conditions.
