Summary:
Knappa High School is the only high school serving grades 9–12 in Knappa School District 4, a small district ranked 128th of 141 in Oregon — the 9th percentile, with 0 stars. With just 131 students, a student-teacher ratio of 11.9, and per-student spending of $25,146, the school has relatively favorable resources and a high free/reduced lunch rate of 61.83%, indicating substantial economic need. Since it is the only high school in the district, district-level high school results are driven entirely by this one school.
Outcomes lag well behind the state. The graduation rate is 70.3% versus 83.0% statewide, and chronic absenteeism is 49.6% — nearly half the student body — compared with 35.3% in the district and 33.5% at state level. On 2025–2026 OSAS tests, ELA proficiency is 33.3% (state: 43.8% all grades, 46% for 11th grade), science is 13.6% (state: 30.6% and 33.8%), and math is under 5% at both all grades and 11th grade, versus 32.9% and 22.9% at state level. Mathematics is the most severe weakness, with a gap of more than 27.9 points at all grades. High school all-grades and 11th-grade results are identical in every subject, consistent with OSAS testing occurring in 11th grade.
The school's rank history is volatile rather than steadily declining: 22nd percentile with 1 star in 2022–2023, 62nd percentile with 3 stars in 2024–2025, then 14th percentile (232nd of 271) with 1 star in 2025–2026. In a school this small, percentages can swing sharply year to year. The data point to attendance and math instruction as the highest-impact areas for improvement, while the strong staffing ratio and spending suggest resources are available to support that work.
