Vasquez High School is the only comprehensive high school in Acton Agua Dulce Unified School District. AADUSD was established in 1881 and has the distinction of being one of the oldest districts in the state of California. Located in the rural community of Acton about fourteen miles south of Palmdale in Los Angeles County, the Acton-Agua Dulce Unified School District boundaries cover over two hundred square miles. Vasquez High School was established in 1993 and graduated its first class in June 1997. Prior to the formation of the high school, students attended Highland High School in the Antelope Valley Union School District.

Vasquez High School initially opened on the campus of the District’s middle school, sharing the campus with junior high students for six years until it relocated to its current site in the fall of 1999. On November 4, 2008, the communities of Acton and Agua Dulce came together to pass the local school bond Measure CF. After the failure of four previous bond campaigns, the communities were finally ready to put “children first” and pass the much-needed bond measure.

With the passage of Measure CF, the Acton-Agua Dulce Unified School District pursued the construction of a fully-comprehensive high school. The Measure CF project list encompassed permanent classrooms, science labs, library, administrative offices, gymnasium, additional restrooms, a cafeteria/multi-purpose room as well as all furnishings and equipment needed for a high school. School construction was completed in several phases, with phase I finishing in the fall of 2015 and phase II culminating in the fall of 2016.  With the help of the community, school board, and district leadership, Vasquez High School has quickly advanced into a permanent, fully-comprehensive campus the students can call their own.  In recent years Vasquez High has been awarded the College Board AP Honor Roll and the US News & World Report Silver Medal, placing Vasquez in the top 9% of all high schools nationwide.
