Unification
The citizens of the Los Angeles City School District voted to become a unified school district on June 7, 1960. It also merged with the Palos Verdes School District and, on July 1, 1961, became the Los Angeles Unified School District. The remainder of the high school district, with only the territory of the Las Vergenes Union School District and Topanga School District, and no high school, renamed itself the West County Union High School District. The new L.A. Unified was only required to provide high school service to the remaining West County district for three years. On October 3, Topanga School District citizens also voted to join L.A. Unified. Since this reduced the West County Union High School District to the same border as Las Virgenes grade school district as of July 1, 1962, the 1935 state law known as the Unification Act caused their automatic unification on that date; the resulting district took the name Las Virgenes Unified School District. Its citizens approved a bond issue and state aid authorization in the April 16, 1963 election, leading to the opening of Agoura High School, 3 years after the dissolution of the 1890 high school district.
