The superintendent of public instruction shall review each application submitted for a school closure to determine if the application provides a conclusive demonstration that one or more unforeseen natural events, mechanical failures, or actions or inactions by one or more persons prevented the school district or charter school from operating the school. Whenever a school district or charter school provides a school day, it shall be considered as meeting all hours, as originally scheduled for that day, toward meeting its program hour offerings, teacher contact hours, and course mix percentage requirements.
