History
Before Thousand Oaks High School opened, high school students in the Conejo Valley attended Oxnard High School and later Adolfo Camarillo High School, both campuses of the Oxnard Union High School District (OUHSD). In response to rapid population growth throughout the district in the postwar years, OUHSD superintendent Joseph W. Crosby began an ambitious school construction program. In 1960, voters approved a school bond measure that enabled the building of several new high school campuses. OUHSD purchased a 50.5 acre 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. Thousand Oaks High School opened in 1962 with a student body of 895; the first principal was Tom Roser, a former social science teacher at Oxnard High School. 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.

On July 1, 1974, the Conejo Valley Unified School District (CVUSD) was formed from the easternmost territory of OUHSD, merging with two elementary school districts serving the Conejo Valley. The new district took control of TOHS and Newbury Park High School, the latter which opened in 1967.

A 350-seat performing arts center opened at Thousand Oaks High School in 1999. In 2000, the campus underwent a major modernization project, addressing heating, ventilation, and air conditioning (HVAC) and ADA accessibility issues.

Thousand Oaks High School had its HVAC replaced in 2018 and the school library was renovated in 2019.

In January 2020, Schneider Electric donated an outdoor classroom shade structure and solar panels to the school. Called the Sustainable Outdoor Learning Environment (SOLE), the 30 × structure seats 40 students, is powered entirely by renewable energy, and features outdoor furniture and an interactive white board. Construction concluded in April 2021.

Academics
Thousand Oaks High School was named a California Gold Ribbon School in 2016–17. In the 2019–20 school year, the mean SAT score was 1206 (604 in Mathematics, 602 in Evidence Based Reading) and the mean ACT composite score was 26.4. The school has specialized programs for research (the Center for Advanced Studies and Research or "The Center"), entrepreneurship and business (ETHOS Entrepreneurship Academy or "ETHOS"), and a majors program. TOHS offers the California Biliteracy Seal to students who demonstrate a high level of proficiency in English and at least one other language.

In 2024, Ramon Moreno Jr., a Center for Advanced Studies and Research student, studied the potential of the chemical compound isonicotinamide (INAM) to extend the lifespan of yeast cells for his project. His project was conducted though the Center program. This project allowed Moreno Jr. to be named a top 40 finalist for Regeneron Science Talent Search, the nation's oldest and most prestigious science research competition for high school students, allowing him to earn up to $25,000 in scholarship money.

Athletics
Thousand Oaks High School athletic teams are nicknamed the Lancers. The school is a member of the CIF Southern Section and competes in the Marmonte League. Thousand Oaks' main rival is Newbury Park High School. The student spirit section is known as the Green Hole.

The TOHS cross-country program owns three CIF State championships. The boys' team won state titles in 1993 and 1994, while the girls' team earned a championship in 1993.

In 2022, the Lancer football team secured its first 10–0 regular season in the program's 55-plus-year history. The Lancers two previous unbeaten regular seasons came in 1964 and 1989, when they were 9–0 and 9–0–1, respectively.
