Original Research by School Decision on Heritage High
Heritage High is a mid-sized high school in Brentwood, a fast-growing suburban community in eastern Contra Costa County that has transformed from an agricultural town into a bedroom community of commuter families. The school sits on the city's western edge, away from the historic downtown where the older Liberty High remains anchored.
Brentwood itself is car-dependent beyond the downtown core, though the city has invested heavily in trails and parks that serve as the primary outdoor gathering spaces. Housing has shifted dramatically from orchards to new subdivisions, and the population has grown substantially over recent decades. Most residents own their homes; the area draws families seeking suburban living and proximity to major Bay Area employers, though residents face long commutes to places like Livermore Labs, Google, Meta, and UCSF. Downtown anchors civic life with a farmers' market, library, parks, and local shops, but day-to-day living reads as a spread-out residential suburb rather than a walkable neighborhood.
Heritage High enrolls a diverse student body, with no single racial or ethnic group forming a majority. White and Hispanic students each make up roughly a third of enrollment, Asian students comprise a substantial share, and Black and multiracial students round out the population. Most students are not economically disadvantaged; the share qualifying for free or reduced-price lunch is modest. The school does not report English learner or special education enrollment percentages, so a parent may want to look into the school directly about its capacity to serve students learning English or those with disabilities.
In the most recent state testing year available, Heritage shows a clear divide across subjects. In English language arts, proficiency reached a solid level. Mathematics proficiency fell to less than half of students, and science proficiency was even lower. These results sit against the backdrop that only a single year of data is on file; longer trends are not available, so it is unclear whether these numbers represent a direction or a snapshot. A parent interested in the school's academic trajectory and support structures in math and science would do well to ask the school about its interventions in those areas and any multi-year patterns.
Data on graduation rates, chronic absenteeism, and overall four-year progress is not available in the public reporting reviewed here, making it harder to assess the full academic health of the school. The school serves all four high school grades in balanced numbers, so the enrollment is stable across cohorts.
Heritage is one of two high schools in Liberty Union High School District, which also includes Liberty High downtown. The district faced no major documented changes in bonds, curriculum, or pedagogy over the recent period that could be confirmed through public sources, though the district has been navigating growth pressures as Brentwood's population expands. A parent evaluating the school should supplement this portrait by visiting the campus, speaking with current students and families, and asking the school directly about its academic supports, course breadth, and any programs or pathways the school offers.
