Original Research by School Decision on San Lorenzo High
San Lorenzo High is a regular public high school serving grades nine through twelve in the unincorporated San Lorenzo community of Alameda County's East Bay. The school is located on East Lewelling Boulevard in a neighborhood of single-family homes that make up much of San Lorenzo's post-WWII planned-community character. The student body is predominantly Hispanic, with meaningful populations of Asian and Black students and a majority of students qualifying for free or reduced-price lunch, reflecting both the community's demographic makeup and economic profile. The enrollment is small to moderate for a comprehensive high school.
Academic performance at San Lorenzo High is markedly low across all tested subjects. State proficiency results from the most recent assessment show that a small fraction of students met proficiency standards in English language arts, and proficiency rates in mathematics and science were substantially lower still. Only one year of data is available, so no trend can yet be established. The school's test results fall well below the midpoint among Alameda County districts. A parent or resident reviewing these numbers should note that state testing does not capture all that a school teaches or how well individual students may be progressing; conversations with the school about what is driving these results, what supports and interventions are in place, and what academic pathways are available would be necessary to fully understand the school's educational program.
The broader context matters here. San Lorenzo Unified School District was identified by the state as needing intensive support due to persistent performance disparities across student subgroups, including students with disabilities, English learners, African American students, and others. In response, the district underwent a Systemic Instructional Review in 2023-24 conducted by WestEd and the Alameda County Office of Education, which generated recommendations to guide instructional improvement across the system. This signals that the district is undertaking multi-year reform work. Families should ask the school and district directly what specific changes have been implemented as a result and what progress is being tracked.
San Lorenzo High shares its East Lewelling Boulevard campus with East Bay Arts High School, a smaller alternative school focused on arts. The district serves the San Lorenzo community through two comprehensive high schools—San Lorenzo High and Arroyo High, located about a mile apart—along with middle and elementary schools. The town itself is stable and owner-occupied, with a strong sense of community identity rooted in its origins as one of the nation's first planned communities. Housing values in the area are substantial; the median home price is high relative to the state and national benchmarks, and rent-to-income costs are considerable. The community is served by Alameda County Library's San Lorenzo branch and local parks, with AC Transit bus service connecting residents to BART stations in nearby San Leandro and Hayward.
At the district level, voters approved a substantial general obligation bond in November 2024 to modernize aging facilities, most more than a half-century old, adding an ongoing property tax cost that families weighing school facility condition against local tax burden will want to factor in. The district also transitioned from at-large to by-trustee-area board elections in 2024, placing board seats under geographic accountability to specific neighborhood areas rather than the community at large.
The school's state assessment data and the district's accountability status indicate that San Lorenzo High would benefit most from careful conversation with staff and leadership about current instructional priorities, available course pathways for different academic levels and goals, and specific supports for students who enter performing below grade level. Graduation rate data was not available in the state reporting, so families will want to ask about that directly.
