Though L.A. Unified was required to provide high school education to Las Virgenes for three years, California law mandated that, if a unified school district did not establish its own high school by September 1965, the district would be annexed to an adjacent district with a high school. In January 1963, LVUSD residents had already voted down construction financing by very narrow margins, and many residents were still advocating a merger into a bigger district. If financing had been voted down again, the Los Angeles County Board of Supervisors would have had to choose an adjacent district to annex LVUSD territory into: L.A. Unified, Oxnard, Santa Monica, or Simi. However, in the April 16, 1963 election, the voters approved the bond issue and state aid authorization — the latter by only four votes — which allowed LVUSD to build Agoura High School and three grade schools.
