Summary

Colusa High is a public high school in Colusa, California, serving grades 9–12 and 431 students. Its graduation rate is strong at 97%, and chronic absenteeism is low at 5%, compared with 18% statewide. The clearest academic concern is mathematics: just 15% of students are proficient, well below the state and district.

English is Colusa’s strongest subject: 59% are proficient, compared with 49% statewide and 41% in Colusa Unified. Among nearby schools with reported results, Colusa is just behind Pierce High in English and ahead of Maxwell Senior High and Williams Junior/Senior High. Math proficiency is 24 percentage points below the state and 17 below the district; it is also lower than Pierce’s and Maxwell’s, though higher than Williams’s. Science proficiency is 24%—12 points below the state and about 1 point above the district. Graduation is close to the district’s 97%, and Colusa’s 5% chronic absenteeism is the lowest among nearby schools with reported figures.

Results are moving in different directions: over four years, English proficiency rose 11 percentage points and science rose 10, while math fell 4 points and its gap with the state widened from 16 to 24 points. SchoolDigger places Colusa at the 45th percentile with 2 stars in 2025–2026, up from the 40th percentile the year before.
