Summary:
Zip code 97499 in Yoncalla, Oregon contains exactly one high school: Yoncalla High School, which serves grades 9–12 with an enrollment of 76 students as part of Yoncalla School District 32. Because it is the only high school in the area, there are no school-to-school comparisons within the zip code; the useful comparisons are between this school, its district, and Oregon state averages.
The school's clearest bright spot is chronic absenteeism, at 26.5% compared with 35.2% in the district and 33.5% statewide — lower is better here, so Yoncalla High is 8.7 percentage points below its district and 7.0 points below the state. Its graduation rate is 74.1%, identical to the district and 8.9 points below Oregon's 83.0%. School-level test scores for 2025–2026 are suppressed by the state, meaning they are unknown rather than zero or a weakness. District-level proficiency trails the state in every subject: English language arts at 27.1% versus 43.8%, math at 14.6% versus 32.9%, and science at 11.1% versus 30.6%. The district is ranked 126th of 141 with 1 star, while the high school's 2024–2025 rank is 134th of 270 — the 50th percentile with 3 stars, up from the 29th percentile with 1 star the prior year, though below its 2022–2023 mark of the 77th percentile with 4 stars.
With only 76 students across four grades, year-to-year metrics can swing sharply, and the small cohort likely explains the suppressed test data. The student-teacher ratio is a low 10.7, and spending is $36,952 per student, reflecting the fixed costs of running a very small high school. Note that the free/reduced lunch figure of 144.74% is anomalous and should not be read as a reliable percentage.
