Summary

Summerville High is a public school in Tuolumne, California, serving grades 9–12, with 508 students in the supplied data. Its 2025–2026 graduation rate was 98%, higher than both the district’s 94% and the state’s 88%, and its dropout rate was 2%, compared with 4% in the district and 8% statewide. But chronic absenteeism was 25%, above the district’s 17% and the state’s 18%, and rose from 22% the prior year. The most important contrast for families is strong graduation alongside a significant attendance concern.

ELA is the school’s clearest academic strength: its 2025–2026 proficiency was 65%, 16 points above the state and second among nearby schools with results, behind Connections Visual and Performing Arts Academy. It was 2 points below the Summerville Union High district result. Math is the largest weakness against state results: 26% proficient was 13 points below the state and 4 below the district; it ranked third among nearby schools with reported scores, behind Connections and Sonora High. Science was 34%, 2 points below the state and 3 below the district, yet ranked second among nearby schools with reported results, behind Connections.

Over time, ELA gained 7 points from 2022–2023 to 2025–2026, although the latest result fell 5 points from the prior year. Math improved 3 points but remained about as far below the state; science fell 3 points over the longer period, despite a 7-point rebound in the latest year. SchoolDigger rates Summerville 3 stars, at the 62nd statewide percentile—down 12 points from 2023–2024. Its 2024–2025 student-teacher ratio of 23.1 was the highest among nearby schools with reported figures. In 2024–2025, 46% of students were free/reduced lunch eligible, a mid-range share among nearby schools with the same measure. SchoolDigger’s subgroup rankings differ sharply from the overall ranking: Hispanic students ranked at the 84th percentile, 22 points above the school overall, while multi-racial students ranked at the 6th percentile, 56 points below.
