Original Research by School Decision on Aragon High
Aragon High is a comprehensive public high school serving grades nine through twelve in San Mateo, a walkable, mixed-use Peninsula city with a strong downtown core and high housing costs. The school enrolls a diverse student body with substantial representation of Asian and Hispanic students, alongside smaller populations of white, multiracial, and other backgrounds. About one in seven students qualify for free or reduced-price lunch.
In English language arts, Aragon students score at proficiency levels well above the midpoint—the school's most consistent strength. Science results sit solidly above the midpoint. Mathematics is the softer area; student proficiency there runs below the midpoint among San Mateo County's districts, which is worth understanding if math is a focus area for your student or family. Only one year of state testing data is available, so trend information is not present; a parent interested in how the school has moved over time may want to check with Aragon directly on prior-year results.
The school offers a regular public high school curriculum without charter, magnet, or Title I designation. Specific course offerings, AP breadth, career and technical pathways, or dual-credit programs are not detailed in available data; families should visit the school website or contact admissions to understand what programs are available beyond the core academic sequence. Staffing, attendance rates, discipline data, and chronic absenteeism figures were not provided.
Aragon sits within San Mateo Union High School District, which in 2020 approved Measure L, a general obligation bond funding capital improvements across the district including new gymnasiums, athletic facilities, and solar and electric-vehicle infrastructure. This bond carries an ongoing property-tax cost for district homeowners—a direct consideration if housing choice matters to your family's budget. The district also made a one-semester ethnic studies course a ninth-grade graduation requirement in 2020, several years before California statewide mandate. This requirement has been locally debated and is part of the standing curriculum any student entering the district will encounter.
San Mateo itself is a sizable city built around a vibrant downtown anchored by Central Park, with restaurants, cafes, shops, and a cinema within easy walking distance. The Walk Score for downtown ranks in the very high range. Three Caltrain stations serve the city—San Mateo, Hayward Park, and Hillsdale—and SamTrans buses connect to other Peninsula communities and parts of San Francisco and Palo Alto. San Francisco International Airport lies about seven miles north. The city's growth is tilting toward higher-density mixed-use housing in and near downtown rather than single-family sprawl; current development includes multi-story rental and residential buildings at several downtown sites, and the Bay Meadows area near Hillsdale Station is adding townhomes, retail, and open space.
Housing in San Mateo is very expensive. Median home values are substantially above the state benchmark, and median rents are correspondingly high. Median household income in the region is strong, though the affordability gap between purchase price and renter income is pronounced. If school choice is tied to where your family can afford to live, this is a material constraint to weigh alongside school quality.
Graduation rate, chronic absenteeism, and overall proficiency comparisons to other county districts were not reported, so the school's standing on those measures cannot be stated here. A parent should view the one year of available test data as a starting point and seek more complete information from the school on its longer-term performance, program depth, and student outcomes.
