Summary:
Dayton High School is the only high school in Dayton School District 8, serving grades 9–12 with 310 students at 801 Ferry St, Dayton, OR 97114-9709. Because it is the sole high school in the district, there are no within-district high-school comparisons to make; the meaningful benchmarks are the district overall, the state, and the school's own three-year history. The district itself ranks 116th of 141 in Oregon, in the 18th percentile with 1 star.
The most striking positive signal is the school's rank trajectory. It moved from 227th of 270 in 2024–2025, at the 16th percentile with 1 star, to 142nd of 271 in 2025–2026, at the 48th percentile with 2 stars — an improvement of 85 rank positions and 32 percentile points in a single year, placing it near the middle of Oregon high schools after two years in or near the lower quartile. Graduation is also a strength: the 2024–2025 rate of 91.4% matches the district and is 8.4 percentage points above the state's 83.0%. In English Language Arts, 47.4% of students were proficient, above the district's 30.3% and the state's 43.8%.
Mathematics is the clearest weakness. Only 18.2% of students were proficient, 14.7 points below the state's 32.9% and only slightly above the district's 17.6%. Science sits near the state average at 29.9% versus 30.6%. Chronic absenteeism is a major engagement concern at 43.2%, compared with 34.2% in the district and 33.5% statewide — more than two in five students chronically absent, even as graduation remains high. The school reports $22,418 per student and a 14.7:1 student-teacher ratio, though the data offers no benchmark for comparison. Note that the reported free/reduced-lunch figure of 161.29% is not a valid percentage and should be treated as a data anomaly rather than evidence about poverty. With only 310 students, year-to-year swings are expected, so the recent improvement is worth watching over time.
