The high school, built in 1972, was originally part of a K-12 complex, which included an elementary and junior high (later a middle school). The elementary school was closed in the mid-1980s due to school district budget cuts, and the middle school was closed in 2005 when Enterprise Middle School was opened in West Richland in the same year. The latest remodel/rebuild was completed in 2007.
