School Meals during School Closures Act This bill allows states or eligible service providers (e.g., school districts) to request a waiver of certain requirements to continue providing no-cost and reduced-cost meals to students during certain school closures. The Department of Agriculture may provide a waiver, with exceptions, to provide meals and meal supplements during a school closure due to a strike or other labor-management dispute; inclement weather, a natural disaster, a public health emergency, unsafe facilities, construction, or repairs; or other unanticipated events.
