Summary

Colusa Alternative High (Continuation) is a 27-student school serving grades 9–12 in Colusa, California. Its 2025–2026 results show no students proficient in English or science and 14% proficient in math, while math is a relative strength compared with nearby schools. The most urgent concern is chronic absenteeism: although it fell from 92% in 2023–2024 to 56% in 2025–2026, it remains 38 points above the state rate and 46 points above the district rate.

Math is the school’s strongest subject relative to nearby schools, but it still trails the state and district: 14% were proficient, compared with a 13% average among nearby schools with reported results, 38% statewide, and 31% in Colusa Unified. English and science are the clearest weaknesses: both were at 0%, versus 49% and 36% statewide, and 41% and 23% in the district, respectively. Nearby reported results averaged 41% in English and 22% in science. These subject results are a concern, though the school’s small enrollment means outcomes may be sensitive to a few students’ results.

Some results are improving: math proficiency rose from 9% in 2024–2025 to 14% in 2025–2026, and the graduation rate increased from 73% in 2022–2023 to 81% in 2024–2025. The latest graduation rate was still 7 points below the state and 10 points below the district. SchoolDigger ranked the school at the 15th percentile statewide in 2025–2026, with 1 star; nearby S. William Abel Academy ranked lower at the 11th percentile, while Williams Junior/Senior High ranked at the 23rd. In 2024–2025, its student-teacher ratio was 27, the highest among nearby schools with reported figures, and 78% of students were free/reduced lunch eligible.
