Ross Elementary, Ross CA - Test Scores & Data

Original Research by School Decision on Ross Elementary

Ross Elementary is a small K-8 public school of roughly three hundred fifty students in the affluent village of Ross, in central Marin County. It occupies a quiet residential setting in a town of large, tree-lined estates where single-family homes dominate and commercial activity is deliberately minimal. The school sits near the village center along Lagunitas Road, close to town civic life and the cultural offerings of the Marin Art and Garden Center.

The student body is predominantly white, with a very small share of students qualifying for free or reduced-price lunch. Demographic breakdown data shows representation across multiple racial and ethnic groups, though the school serves primarily families of means reflective of the community's wealth. Specific data on students with individualized education programs or English learners was not available, so a parent may want to inquire about those services directly.

State assessment results from the most recent year show broad strength in both English language arts and mathematics across the tested grades. In ELA, proficiency ranges from the mid-eighties to mid-nineties by grade, with third grade performing particularly well. Math proficiency similarly clusters in the high eighties and low nineties for most grades, with a small dip at seventh grade but recovery by eighth. Science results are available for fifth and eighth grades, and both show weaker proficiency than reading and math, suggesting an area the school may be addressing or where additional support could help. The school's overall proficiency index positions it in the top quartile among districts across Marin County.

The school's structure as a combined K-8 building means students remain in one community through eighth grade before transitioning elsewhere. This can offer continuity and a tight-knit environment, though families seeking a traditional elementary-only setting would need to plan for a shift at grade five or six. The town itself is car-dependent despite its compact core; most daily errands require driving to neighboring towns for services. Community life centers on parks, the cultural center, and schools rather than commercial downtown activity.

Housing in the zipcode is well above regional and national benchmarks, reflecting Ross's status as one of Marin's most exclusive residential areas. For families considering the area, affordability presents a significant consideration. The town's growth is constrained by design, with zoning that limits density and favors single-family homes. Recent housing policy emphasizes accessory dwelling units and workforce housing tied to institutional projects rather than broad new development.

Ross Elementary offers a peer environment of students whose families have secured housing in an exceptionally expensive market. The school's strong academic performance in core subjects, paired with stable funding reflective of the community's resources, positions it as a solid academic pathway for the early grades. Parents should weigh this against the town's size, the school's isolation from the broader school system's diversity, and the family's fit with a small, affluent residential community.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
