Summary

Concord High is a public grades 9–12 high school in Concord, California, serving 1,137 students in Mt. Diablo Unified. Its results show a clear contrast: in 2025–2026, test proficiency was below state and district levels in all three subjects, but graduation was strong—98%, compared with 88% statewide—and dropout was low at 2%.

ELA is Concord’s strongest subject relative to nearby schools, while mathematics is its weakest. In 2025–2026, proficiency was 40% in ELA, 17% in mathematics, and 20% in science; the state results were 49%, 38%, and 36%, respectively, and the district results were 49%, 39%, and 35%. Among Concord and four nearby comprehensive high schools, it ranked third of five in ELA and fourth of five in mathematics and science. Concord’s graduation rate was the second-highest among those nearby schools, behind Northgate High and just above College Park High; Concord also had the lowest dropout rate.

Over the four reported years, ELA proficiency fell 6 percentage points, while mathematics rose 5 points and science rose 5 points. SchoolDigger gives Concord 2 stars and places it at the 33rd percentile statewide, down 12 percentile points since 2023–2024 and 29 since 2017–2018. Its 2024–2025 student-teacher ratio was 19.5, near those of nearby comprehensive schools. In that school year, 70% of students were free/reduced lunch eligible; this is a reported school measure. SchoolDigger’s subgroup ranking shows a notably weaker statewide standing for Asian students: the school ranked at the 1st percentile for that group, compared with the 33rd overall. Its ranking for Disabled Students also dropped sharply, from the 81st percentile in 2018–2019 to the 20th in 2021–2022.
