Please note that because of Missouri law, classes can start no earlier than 14 calendar days before the first Monday in September. Also, Districts are required to offer at least 1,044 hours of instruction annually. If a school district builds a calendar with at least 1,104 hours of instruction, it assures no snow days will be required to be made up. This allows the district to schedule a final date for the school calendar. The 2021-2022 Neosho School District calendar includes more than 1,104 hours.
