Union Gap School District was the second district formed while Washington State was still a territory; the charter was signed by Ulysses S. Grant. The district is comprised of one school building housing approximately 640 students in grades preschool-8. Due to continued voter support, students and staff moved into a new facility in September 2009. The school has just completed construction for an additional wing which added six classrooms to the existing building. The primary purpose of the addition was to lower class sizes in Kindergarten through 3rd grade.

The staff consists of approximately 80 certificated, classified and administrative staff. Union Gap hosts a multitude of events: sports competitions, extended day and evening student learning activities, community and District events, academic celebrations, parent learning nights, musical performances, etc. Union Gap School is used to host AAU sports practice and events, and class fundraisers open to the public. Our school is a hub for community and family involvement.
