Original Research by School Decision on San Marin High
San Marin High sits on its own campus in the northern part of Novato, a predominantly residential city in Marin County that stretches roughly 29 miles north of San Francisco. The school is one of two comprehensive public high schools in Novato Unified, serving ninth through twelfth grade as a standard public, non-charter school.
The school enrolls a mid-to-large high school population for its grade band, with fairly even distribution across all four grade levels. Roughly a quarter of students qualify for free or reduced-price lunch, which is on the lower end for a California public high school and reflects the relative affluence of the surrounding community. The student body is majority white, with Hispanic students making up a substantial second-largest group, followed by smaller Asian, multiracial, and other populations. Data on English learners and students with IEPs was not available in what was provided.
On state assessments, the most recent results show the school performing solidly in English language arts, with roughly two-thirds of students reaching proficiency. Science sits in the mid-range. Math proficiency lands meaningfully lower, with fewer than half of students meeting standards. Because only a single year of data is available here, trend direction cannot be assessed. A parent who wants to understand whether these results reflect an upward or downward arc, or how they compare to Novato High across town, would want to look into that directly with the district or through California's state dashboard. Comparison data relative to the other districts in Marin County was not available at the school level from what was provided.
Graduation rate data was not reported in what was provided. Program offerings were also not available, so it is not possible to describe AP course breadth, dual enrollment, career pathways, or sports from this data alone.
The housing market around San Marin reflects the broader Marin County reality: home values are substantially above both the state and national medians, and estimated monthly mortgage costs sit at a level most households would find a stretch. Rents, while lower than buying, still represent a very high share of a typical household budget. Prices have drifted very slightly downward year over year. For families considering this zip code, the cost of entry is one of the more significant practical considerations.
Novato Unified carries some financial context worth knowing. The district publicly reports receiving among the lowest per-student funding in Marin County. Voters renewed an existing parcel tax in 2023 to support teacher retention and core programs, and as of June 2026 a supplemental measure was on the ballot that, if approved, would add a further annual cost per parcel for several years. These taxes are a real property cost but also represent the mechanism the district uses to maintain program stability when state funding falls short. The district navigated an enrollment-decline scare several years ago, reaching the point of recommending an elementary school closure before pausing that process. Enrollment has since stabilized. Starting with the 2023-24 school year, the district expanded arts and music programming using Proposition 28 state funding.
Novato itself is walkable at its core, with a restored downtown along Grant Avenue that has restaurants, boutiques, and a multi-use pathway connecting to SMART commuter rail. Outside that core, daily life is more car-oriented, with major retail in highway-adjacent shopping centers. The city's housing pipeline is active but slow, with only modest new construction permitted recently despite state targets; a handful of larger mixed-use and residential projects are in various stages of approval.
For a family choosing between the two Novato comprehensive high schools, the data here does not distinguish them programmatically, since program data was absent for San Marin. What the data does show is a school with a strong ELA result, middling science, and a softer math picture, sitting in a high-cost community within a district that depends on voter-approved supplemental funding to sustain its academic offerings.
