Summary:
Zip code 94618 has one listed middle school, Claremont Middle, serving grades 6–8 and enrolling 487 students. Its 2024–25 student-teacher ratio was 17.1, and its 2025–26 chronic absenteeism rate was 18%, close to California’s 18% and below Oakland Unified’s 30%. The most important finding is that Claremont’s 2025–26 proficiency results were well above state and district averages in ELA, math, and science.
Claremont is the sole listed school, so there is no other local school to rank at the top or bottom. Its results stand out against the wider benchmarks: ELA proficiency was 68%, compared with 49% statewide and 34% in the district; math was 57%, compared with 38% statewide and 28% in the district; and science was 58%, compared with 36% statewide and 27% in the district. The school’s advantage over California was largest in science, at 22 percentage points, though it was substantially ahead in all three subjects.
Results improved from 2024–25 to 2025–26 in every subject, with the sharpest rise in science: up 17 percentage points, compared with 5 points in math and 2 points in ELA. Science also became the clearest relative strength: its advantage over the state widened from 8 to 22 points. SchoolDigger’s ranking improved from 524th of 2,783 schools (81st percentile) in 2023–24 to 341st of 2,703 (87th percentile) in 2025–26. For context, 56% of students were free/reduced lunch eligible in 2024–25. These figures describe one school and do not allow comparisons among schools in the zip code; the number of schools in SchoolDigger’s rankings also changed over time.
