Summary:

Claremont Unified includes 11 schools—eight classified as elementary, one middle school, and two high schools—serving students from elementary through high school. The available proficiency results cover 2024–2025 and 2025–2026. The biggest contrast is between the high schools: in 11th grade, Claremont High outscored San Antonio High (Continuation) by 57 percentage points in ELA, 47 in math, and 44 in science. Their graduation rates were 97% and 72%, respectively. The most important takeaway is that reported outcomes vary sharply from school to school, especially between the two high schools.

Sycamore Elementary leads the 2025–2026 all-grades results, with 77% proficient in ELA, 70% in math, and 83% in science. Its ELA result is just 1 percentage point above Claremont High’s 76%; its leads over the next-highest schools are 9 points in math and 22 in science. By contrast, San Antonio has the lowest reported results: 19% in ELA, 5% in math, and 15% in science. Among regular elementary schools, Vista del Valle Elementary is weakest in math and science, at 32% and 27%; its fifth-grade math result is 17%, versus 37% statewide. Danbury Special Education’s 2025–2026 proficiency figures are state-suppressed.

Recent changes and school context add nuance: across schools with results, average proficiency rose by about 1 point in ELA and 4 in science, but math gains lagged the state’s. Mountain View Elementary and Sumner Elementary gained 11 and 9 points, respectively, in SchoolDigger’s statewide percentile rankings over three years; Vista lost 4, while Sycamore remains high at 92 after reaching 95. School context does not sort neatly with scores: Sycamore has the highest listed student–teacher ratio among K–6 schools, 26.9, while Oakmont’s is 20.7. The 2024–2025 free/reduced lunch eligible measure ranges from 22% at Sycamore to 53% at Vista among regular elementary schools; these figures offer context, not an explanation of results.
