Seeking to deal with the problem, Oak Park residents petitioned for annexation to Las Virgenes but were rejected in 1974. In 1977, they created the Oak Park Unified School District and broke ground for the high school in 1978. Students were housed in trailers from 1979 to 1980 until the school began admitting students at its present site in 1981. It functioned as both middle and high school until 1992, when nearby Medea Creek Middle School began educating sixth through eighth-grade students.
