    Calendar Development

    • Union negotiation outcomes determine the first day of school and school breaks for future school years.
    • The calendar is developed in cooperation with all of the bargaining groups representing Seattle Public Schools employees.
    • The calendar is structured to provide a full week of instruction following spring break and before the beginning of the spring testing period.
    • It provides specific dates that will be used as make-up days in the event that inclement weather necessitates school closures.
