Original Research by School Decision on Los Altos High
Los Altos High is a regular public high school serving grades 9 through 12 in Hacienda Heights, a car-oriented, largely built-out residential suburb in the San Gabriel Valley east of Los Angeles. The school draws from an economically stretched community where a substantial share of students qualify for free or reduced-price lunch.
The school's student body reflects the neighborhood's demographics. The vast majority of students are Hispanic, with smaller populations of Asian, White, and multiracial students. The enrollment sits at a typical size for a comprehensive California high school serving a suburban district.
On state testing, Los Altos reports proficiency in English language arts that sits above the midpoint for schools across Los Angeles County. Mathematics proficiency is substantially lower, falling below the midpoint. Science proficiency is the lowest of the three tested areas. State testing data was not available for prior years, so it is not possible to see whether performance is improving, stable, or declining. The school's graduation rate was not provided in the available data.
Hacienda Heights itself is a mid-sized, ethnically diverse community with a median home value well above the state average and rents that consume a notable share of typical household income. The area is dominated by single-family homes built in the 1960s and 1970s. Commercial activity is dispersed along major corridors like Colima Road and Hacienda Boulevard rather than clustered in a downtown, and daily life requires a car for most errands. The community anchors itself in county parks, including the regional Schabarum Park, a public library, and bus transit through Foothill Transit and the county's Heights Hopper Shuttle.
The district itself, Hacienda La Puente Unified, is in active transition. In November 2023 the board approved a reconfiguration plan that closed four schools, citing declining enrollment. That decline is projected to continue, raising the possibility of further consolidation. For families considering the area, this means the school landscape may shift in coming years. As part of its curriculum work, the district has adopted an Intersectional Ethnic Studies curriculum for all grades, with expansion toward making Ethnic Studies a graduation requirement and embedding it across English, Spanish, and film studies courses. Los Altos offers Ethnic Studies classes in English Language Arts starting in the 2024-25 school year.
Parents investigating Los Altos may want to ask the school directly about graduation rates, attendance, discipline, and the specific program offerings available at the school, as these details were not in the publicly reported data reviewed here. The math and science proficiency figures are notably soft and may be worth exploring further with the school to understand what supports are in place for students in those subjects.
