In response to rapid population growth throughout the district in the postwar years, OUHSD superintendent Joseph W. Crosby began an ambitious school construction program.

[5] OUHSD purchased a 50.5-acre (20.4 ha) site on Moorpark Road from Janss Corporation for $245,693.45 and awarded a $2.275 million building contract to Viola Incorporated, more than $200,000 over budget.

The campus was shared with the Valley Oaks School District, educating 300 students in grades K–8 while Meadows Elementary of the Arts and Sciences was being built.

[8] In 2000, the campus underwent a major modernization project, addressing heating, ventilation, and air conditioning (HVAC) and ADA accessibility issues.

[10] In January 2020, Schneider Electric donated an outdoor classroom shade structure and solar panels to the school.

TOHS offers the California Biliteracy Seal to students who demonstrate a high level of proficiency in English and at least one other language.
