The question of which is the richest high school in California has two different answers depending on what you mean by rich. If you mean the school serving the wealthiest community by household income, the data points clearly to a cluster of small, exclusive communities in the San Francisco Bay Area where median household incomes exceed $400,000 and per-pupil spending runs more than double the state average. If you mean the school with the most funding, the answer is also in this same geography. And if you mean the school that turns that wealth into the strongest academic outcomes, the results are surprising in ways that challenge the assumption that money and school quality automatically align.
The Wealthiest School District in California
By median household income, Hillsborough City Elementary in San Mateo County ranks as the wealthiest district in California among active districts with at least 100 students. Households in the district have an average annual income of $437,655, compared to the statewide average of $111,622, according to U.S. Census Bureau American Community Survey data. Due in part to the strong local tax base, education spending in the district is higher than the state average, with per pupil spending of $22,821 compared to a California average of $13,831.
Hillsborough is an incorporated town in San Mateo County on the San Francisco Peninsula, with no commercial districts, no apartments, and a minimum lot size that effectively limits residency to the very wealthy. Its public school district serves only elementary and middle school grades, meaning Hillsborough students feed into San Mateo Union High School District for high school rather than attending a Hillsborough-specific high school. The nearest equivalent at the high school level is Crystal Springs Uplands School, a private institution, or Burlingame High School for public school students from the area.
The high school that most directly inherits Hillsborough's wealth profile is not a public school at all. The public high schools serving the wealthiest California communities tend to be in small, affluent enclaves where the community wealth flows into the school through a combination of high property tax bases, parent foundation contributions, and the concentrated human capital of a highly educated parent community.
The Public High Schools Serving California's Wealthiest Communities
Several California public high schools serve communities so wealthy that the schools function more like well-resourced private schools in terms of facilities, programs, and community investment, while remaining technically public and free to attend.
San Marino High School in San Marino, Los Angeles County, is the most academically elite public high school in Southern California by test scores and community wealth profile. San Marino High enrolls 886 students and posts 94.47% ELA and 87.11% math proficiency on 2024 CAASPP assessments. The San Marino High scores page shows sustained near-perfect performance across multiple assessment cycles. San Marino is a small, exclusively residential city in the San Gabriel Valley with a predominantly Chinese American population, no commercial development, and among the highest property values in Los Angeles County. The school receives significant supplemental funding through parent foundations that fund positions and programs the state allocation doesn't cover.
Piedmont High School in Piedmont, Alameda County, posts 93.16% ELA and 79.26% math proficiency with 733 students enrolled, making it the highest-scoring small public high school in the Bay Area. The Piedmont High scores page reflects a school embedded in one of the Bay Area's most exclusively wealthy small cities. Piedmont is an incorporated city entirely surrounded by Oakland with no commercial property, where the median home price has historically exceeded $2 million. The Piedmont Education Foundation supplements the school's budget by hundreds of thousands of dollars annually, funding counselors, librarians, and enrichment programs that state funding doesn't support.
Lynbrook High School in San Jose posts 93.72% ELA and 92.21% math proficiency, the highest math score of any school in this comparison, serving the affluent West San Jose communities near Saratoga. Lynbrook is part of Fremont Union High School District and draws from neighborhoods where the median household income exceeds $200,000 and the parent population is heavily concentrated in Silicon Valley technology and engineering careers. Its math performance is among the highest of any public high school in California.
Saratoga High School in Saratoga posts 88.69% ELA and 84.10% math with 1,161 students, serving one of the Silicon Valley's most exclusive residential communities. Saratoga, a small city in the Santa Clara County foothills, has median home prices consistently above $3 million and a population heavily concentrated in technology and medical professionals. The Los Gatos-Saratoga Joint Union High School District benefits from one of the strongest property tax bases per student of any high school district in California.
Monta Vista High School in Cupertino posts 87.82% ELA and 89.62% math with 1,630 students, also within Fremont Union High School District. Cupertino is home to Apple's headquarters and has a large, academically oriented Chinese American and Indian American population that drives extraordinarily high academic expectations and outcomes. Monta Vista is one of the most academically intense public high schools in California, with AP enrollment rates and National Merit Scholar production that rival elite private schools.
The Bay Area's Wealthy Contra Costa Corridor
The communities of Orinda, Moraga, and Lafayette in Contra Costa County form another cluster of wealthy public high schools that consistently outperform the state average by large margins. Miramonte High School in Orinda posts 87.68% ELA and 72.73% math. Campolindo High School in Moraga posts 87.01% ELA and 67.31% math. Acalanes High School in Lafayette posts 87.07% ELA and 67.24% math. All three serve communities where median household incomes are well above $200,000 and parent foundations provide substantial supplemental funding.
Palo Alto: The Name-Brand Wealthy School District
Palo Alto Unified School District is perhaps the most discussed wealthy school district in California given its proximity to Stanford University and the heart of Silicon Valley, and the schools live up to the name. Palo Alto High School, known locally as Paly, posts 72.29% ELA and 70.13% math with 1,891 students. Henry M. Gunn High School posts 83.59% ELA and 77.64% math with 1,643 students. Both are strong schools serving an extraordinarily educated parent community, but their scores sit somewhat below the San Marino and Piedmont peak, reflecting the economic diversity that comes with Palo Alto's larger geographic footprint and the presence of some more economically mixed neighborhoods within the district.
The Palo Alto district is also notable for the pressure it has placed on students historically. The district has grappled openly with student mental health crises tied to intense academic competition, and the Palo Alto Unified School District asks parents to make an annual donation of $800 per child, according to Stanford University professor Rob Reich, with neighboring Menlo Park asking $1,500. These parent contributions supplement state funding in ways that widen the gap between wealthy and lower-income districts.
The Beverly Hills Surprise
Beverly Hills High School is perhaps California's most famous public high school by popular culture recognition, having appeared in countless films and television shows as the archetype of the wealthy California school experience. The data tells a more complicated story.
Beverly Hills High School in Beverly Hills posts 61.73% ELA and 48.20% math with 1,173 students, scores that are above the California state average of 47.1% but well below San Marino, Piedmont, Lynbrook, or Saratoga. For a school serving one of the most famous wealthy zip codes in the world, the academic performance is unexceptional by the standards of California's top public high schools.
The explanation lies partly in Beverly Hills's demographic diversity relative to the more homogeneous wealthy enclaves. Beverly Hills has a more economically diverse residential population than Piedmont or San Marino, including a significant share of renters and middle-income households alongside its ultra-wealthy enclaves. The district also faces the specific challenge of a community where family wealth does not necessarily translate to the kind of concentrated academic culture that drives extreme performance at schools like Monta Vista or Lynbrook. Wealth and academic intensity are different things, and Beverly Hills illustrates that distinction clearly.
The Funding Gap and What It Actually Produces
California's Local Control Funding Formula, implemented in 2013, was specifically designed to direct more state funding to districts with higher concentrations of low-income students, English learners, and foster youth. Districts in the bottom quintile receive nearly $6,000 less per enrolled student than the highest-funded districts in California in 2024-2025. The wealthiest districts benefit from high property tax bases that generate local revenue the formula doesn't fully offset.
What the data from these wealthy schools shows is that wealth translates to high academic performance most powerfully when the community has a specific cultural orientation toward academic achievement, not just financial resources. San Marino, Piedmont, and Lynbrook, with their concentrated immigrant and professional populations, produce the highest scores. Saratoga and Monta Vista, serving Silicon Valley engineering families, produce the strongest math performance in the state. Beverly Hills, famous but demographically mixed, performs more modestly.
The wealthiest high school in California by community income and per-pupil resources is embedded in the San Francisco Peninsula corridor. The wealthiest high school by academic outcomes, which may be the more meaningful measure of what school wealth actually produces, is probably San Marino High School, Lynbrook, or Piedmont High, three schools whose community investment in education shows up in sustained near-perfect proficiency rates across multiple years.
