High Schools in Cascade School District 5

Cascade School District 5 has two high schools serving grades 9–12: Cascade Senior High School in Turner, with 795 students, and Cascade Opportunity Center in Aumsville, with 83 students. Together they enroll 878 students, and Cascade Senior High accounts for about 90.5% of that total. The Cascade School District 5 district itself ranks 21st of 141 Oregon districts, at the 85th percentile with 4 stars.

Cascade Senior High School posts strong outcomes: a 94.7% graduation rate, 18.5% chronic absenteeism, and 11th-grade proficiency of 60.2% in ELA, 28.8% in math, and 33.9% in science — above district and state figures, or essentially at state in science. Its rating has slipped slightly, from 4 stars and the 70th percentile in 2024–2025 to 3 stars and the 69th percentile in 2025–2026. Cascade Opportunity Center shows a real one-year rank gain, from the 13th percentile and 1 star to the 37th percentile and 2 stars, but absolute outcomes remain low: a 53.7% graduation rate, 55.8% chronic absenteeism, 9.1% math proficiency, and 25.0% science proficiency, with ELA at 53.8%.

Notably, free/reduced lunch is nearly identical at both schools, about 63.8%, so that measure alone does not explain the outcome gap. Math is the widest academic gap, especially at the Opportunity Center (53.8% ELA versus 9.1% math). ELA is a relative strength at both schools, exceeding the state's 46.0%. Reported per-student spending ($21,250 versus $4,706) and student-teacher ratios (17.3 versus 32.1) differ sharply, though alternative schools are often funded differently and small enrollment can distort per-pupil figures. Test scores are 2025–2026 OSAS; graduation, absenteeism, lunch, spending, and staffing data are 2024–2025.
