The desire of the local residents to have a free public education for their children led to the formation of the Los Altos School District in February 1909. During this time, of land along San Antonio Road was purchased and the construction of the first school in the region,
San Antonio School, was built. It catered to students in grades K through 8, and was the only academic institution until the ending of
World War II. In the years 1948 through 1961, the city was faced with an increasing student population and state mandates against having single schools with greater than 800 students. In 1948, the district annexed lands and purchased the old Purissima School site (in
Los Altos Hills) from the neighboring
Palo Alto School District. During this time of expansion, the district included sixteen different schools. Enrollment peaked in 1966, then slowly declined. The original San Antonio School was demolished and sold, while the number of facilities dwindled. The district currently consists of nine open regular schools, comprising seven elementary and two intermediate schools. ==API Scores==
