    2017-18 School Year Calendar

    The school calendar is negotiated between Seattle Education Association and the district. The Seattle School Board adopted the 2017-18 school calendar at the June 7, 2017, board meeting.

    Students are released 75 minutes early every Wednesday, except for the first day of school. This is to support improved teacher collaboration and student academic performance.
