Summary:
ZIP code 95932 has five schools in Colusa Unified, serving elementary and middle-school grades, high school, and alternative programs, with 1,470 students combined. The three larger schools enroll 430 to 553 students, while the two alternative schools enroll 27 and 29. Across schools with reported results, the simple averages were below state scores in ELA by 15 percentage points, math by 10 points, and science by 20 points; the clearest exception is strong math at James M. Burchfield Primary. Most important, results are uneven by school and subject rather than uniformly strong or weak.
Colusa High leads reported all-grade ELA, with 59% proficient versus 49% statewide, and has a 97% graduation rate compared with 88% statewide. Burchfield leads math at 56%, 17 points above the state’s 38%; its strength does not extend to ELA, where it scored 39% versus 49% statewide. George T. Egling Middle leads reported science at 24%, still 12 points below the state. At the bottom, Colusa Alternative High (Continuation) scored 0% in ELA and science and 14% in math. Chronic absenteeism is also high at Continuation (56%) and Colusa Alternative Home (57%), versus 18% statewide; Colusa High’s rate is 5%.
Reported results improved from 2024–2025 to 2025–2026 among schools with results in both years: matched-school averages rose 4 points in ELA, 4 in math, and 6 in science. SchoolDigger’s statewide rankings also improved recently: Egling moved from the 34th to the 45th percentile, and Colusa High from the 40th to the 45th. For context, reported student-teacher ratios ranged from 17.7 to 28.4 in 2024–2025, and all five schools reported 66% to 79% of students as free/reduced lunch eligible that year; these figures do not explain school results. Because schools serve different grades and the alternative schools are very small, all-grade comparisons are broad snapshots.
