Founded in 1901, the district operates 11 schools: seven full high schools, a continuation high school, an adult school, and two specialized schools. Two small high schools are being planned. More than 300,000 residents live within the district boundaries. Operating with an annual budget of over $100 million, OUHSD employs more than 600 teachers who collectively educate nearly 20,000 students in grades 9-12. In 1974, the Conejo Valley Unified School District was established in Thousand Oaks. Two schools within CVUSD's boundaries, Thousand Oaks and Newbury Park high schools, were transferred to the new district. As of 2015, the superintendent is Penelope DeLeon, Ed.D. DeLeon was previously the Chief of Secondary Schools for the Fontana Unified School District. Previous superintendents include Gabriel Soumakian, EdD, Bob Carter, Jody Dunlap, Gary Davis, Bill Studt, Ian Kirkpatrick, Bob Carter and Joseph W. Crosby. Rio Mesa, Hueneme, and Channel Islands high schools were part of an ambitious building program funded by a school bond measure passed during Crosby's tenure as the district accommodated the area's growing population. Measure H, a $135 million bond measure, passed by voters in 2004 to build two new schools and make improvements to existing campuses. The bond paid for two new swimming pools for Camarillo and Hueneme high schools that were finished in 2014. A new high school in Camarillo, Rancho Campana, was funded through the bond and completed in the fall semester of 2015. , OUHSD was searching for new sites in Oxnard for two more campuses that will be intentionally smaller than the existing high schools. On November 13, 2019, the district's Board of Trustees voted to purchase land for one of these new schools, a parcel in the Colonia neighborhood of Oxnard, for $26.9 million. Named Del Sol High School, the campus is scheduled to open in 2022.
