Summary
Hidden Hills Elementary is a K–5 school in San Ramon, in the San Ramon Valley Unified district, serving 486 students. Its results remain well above California averages, but scores have dropped since 2022–23 and the school now trails its district in English language arts (ELA). The most important takeaway is that strong state-level results mask a declining trend and a weaker position in ELA than families might expect from the school’s high statewide standing.
Compared with nearby schools, science is the school’s strongest subject and ELA its weakest: science proficiency was 67%, placing it third among 11 schools and above the nearby average of 63%; ELA was 76.7% versus a nearby average of 77.2%, placing it seventh. Math was 78%, eighth among the 11 schools and just below the nearby average of 79%. The school exceeded state rates in all three subjects—by 31 points in science, 39 in math and 27 in ELA—but was 4 points below the district in ELA, while 2 points above it in math and 1 point above it in science. Grade-level results also vary: fourth-grade math was 73%, 6 points below the district and ninth among nearby schools, while fifth-grade ELA was 80%, third among nearby schools.
From 2022–23 to 2025–26, proficiency fell by 6 points in ELA, 9 in math and 14 in science; the school’s advantages over state rates narrowed by 8, 13 and 20 points, respectively. SchoolDigger still gives the school 5 stars and ranks it 334th of 5,804 California schools, at the 94th percentile, though its percentile has slipped from 98 in 2021–22 through 2023–24. Context measures are close to local norms: the 2024–25 student-teacher ratio was 20.9, compared with a nearby average of 21.1, and 11% of students were free/reduced lunch eligible in 2024–25, above the nearby average of 9%. Chronic absenteeism was 6% in 2025–26, below the district’s 8% and state’s 18%. One notable subgroup result: SchoolDigger’s 2025–26 statewide ranking places Asian Students at the 72nd percentile, below the school’s overall 94th percentile, reflecting a lower relative standing in how well the school serves this group.
