Summary
Butte Valley High is a public high school in Dorris, California, serving grades 9–12 with 94 students; there are no other schools within 20 miles. Its 2025–26 test results show a clear challenge: all-grades proficiency was 35% in English language arts (ELA), 20% in math, and 10% in science, well below California’s results in every subject.
ELA is the school’s strongest subject compared with both the state and its district, while science is its weakest relative to the state and its smallest advantage over the district. The school’s results were 14 percentage points below the state in ELA, 18 below in math, and 26 below in science. At the same time, it scored 19 points above the Butte Valley Unified district in ELA, 10 above in math, and 4 above in science. These district advantages do not mean the school is close to state proficiency. No nearby-school results were supplied, so local school comparisons are unavailable.
Longer-term results are mixed: from 2022–23 to 2025–26, ELA proficiency fell 11 percentage points, while math rose 12 and science rose 2. The latest results improved on the prior year in all three subjects. SchoolDigger placed the school at the 27th percentile statewide, rank 1,561 of 2,137, with 1 star in 2025–26—a 9-point percentile gain from the prior year, but still below its 38th-percentile standing in 2022–23. The student-teacher ratio was 13.5 in 2024–25, and 77% of students were free/reduced lunch eligible that year. Graduation is a bright spot: the rate was 91% in 2025–26, up 23 percentage points from 2021–22 and 3 points above the state. By contrast, chronic absenteeism rose sharply, from 10% in 2024–25 to 31% in 2025–26.
