Original Research by School Decision on Acalanes High
Acalanes High is a four-year public high school in Lafayette serving a mid-sized student body drawn from Lafayette, Moraga, Orinda, and Walnut Creek. The school sits in a residential East Bay community anchored by a walkable downtown along Mt. Diablo Boulevard, with the Lafayette BART station nearby, and draws from neighborhoods ranging from close-in bungalows to hillside estates. The housing market in the zip code is at the high end for the region, making this a largely affluent student population; a small share of students qualify for free or reduced-price lunch, and the student body is predominantly white, with smaller shares of Asian, multiracial, and Hispanic students.
On the most recent state assessments available, Acalanes students showed strong proficiency in English language arts, with a clear majority meeting or exceeding standards. Mathematics proficiency sits noticeably lower, at a level that reflects a pattern common in many California high schools where math demands diverge from reading comprehension gains. Science proficiency falls between the two, suggesting variable preparation or engagement across the sciences. Only one year of testing data is on file, so it is not yet possible to track whether these results are stable or part of a trend. The school's four-year graduation rate and chronic absenteeism data were not available, limiting what can be said about completion and daily engagement.
The district context matters significantly here. Acalanes Union High School District is among the lowest state-funded high school districts in California, meaning the school relies heavily on local parcel-tax revenue to support programs and staff. In May 2025 a proposed parcel tax was defeated, falling short of the two-thirds approval required. That failure triggered roughly five million dollars in budget reductions for the 2025-2026 school year, with consequences a parent should understand clearly. Class sizes have grown larger, elective course options have narrowed, professional development for teachers has been cut, and supply budgets have been scaled back. The district has indicated that further reductions are likely in subsequent years without new revenue. Additionally, some district staff positions, including librarians and counselors, are being considered for elimination or reduction.
The school offers a regular high school program without magnet or charter designation. Its website was not provided in the data, so details about specific AP offerings, career pathways, internship programs, or other specialized pathways cannot be drawn from what was available. A parent interested in the breadth of upper-level courses, advanced placement access, or career and technical education should contact the school directly, as this information was not documented here.
Lafayette itself is in a period of growth transition. The city has been directed by state law to plan for substantial new housing units and has recently settled a Housing Element lawsuit, with new multifamily and mixed-use projects now opening near downtown and the BART station. The civic anchors include the Lafayette Library, Lafayette Reservoir for recreation, and the town's pedestrian-friendly downtown. This context may shape school enrollment in coming years.
For a family considering Acalanes, the immediate reality is that budget constraints are active and visible. Class sizes are larger now than they were; course selection is more limited; and the school's reliance on local revenue rather than state funding means that program quality hinges on whether the community can pass a future parcel tax. The school's academic standing in English is solid. Math and science proficiency are areas where a family might want to inquire further about support structures, prerequisite rigor, or teaching resources available to students who are struggling. A parent should ask the school directly about current AP course availability, whether counseling and library services are fully staffed, and what the plan is for operating without the parcel-tax revenue the district had counted on.
