SchoolDigger Rank ?

of 2,135 California High Schools

Better than 98% of California high schools

Summary

Carlmont High is a public high school serving grades 9–12 and 2,360 students in Belmont, California. Its 2025–26 results are strong across English language arts (ELA), math, and science: 87% of students were proficient in ELA, and 75% in each of math and science. The most important finding for families is that Carlmont led nearby schools with comparable reported results in all three subjects and substantially outperformed both the state and its district.

Carlmont’s advantage over the state was 38 percentage points in ELA, 37 in math, and 39 in science; its leads over the Sequoia Union High district were 19, 24, and 21 points, respectively. It also outscored the next-highest nearby school with reported results, Aragon High, by 6 points in ELA, 10 in math, and 13 in science. Other outcomes are strong, too: graduation was 98%, versus 88% statewide and 92% districtwide, while chronic absenteeism was 10%, below the state’s 18% and district’s 19%. However, Aragon High had lower chronic absenteeism, at 7%.

Results over time are mixed: from 2022–23 to 2025–26, ELA proficiency fell 4 points, math was nearly unchanged, and science rose 1 point. Even so, Carlmont’s lead over the state narrowed in all three subjects; the latest science result also rose 8 points from the prior year. SchoolDigger gave Carlmont five stars and a 98th-percentile statewide ranking in 2025–26, just above Aragon High at the 97th percentile. Carlmont’s 2024–25 student-teacher ratio was 19.6, and 9% of students were free/reduced lunch eligible that year; California is identified in the data as a statewide-free-meals state, so read that measure in context. SchoolDigger’s 2023–24 ranking for English Language Learner Students was at the 68th percentile, below Carlmont overall that year. Its ranking for Low Socio Economic Status Students rose from the 80th percentile in 2024–25 to the 94th in 2025–26, while the overall ranking was 98th.
