Best High Schools in Zip Code 97360

ZIP code 97360 covers Mill City, Oregon, and contains exactly one high school: Santiam Junior/Senior High School, a combined junior/senior high serving grades 6–12 with 319 students, part of Santiam Canyon School District 129J. Because it is the only school here, there is nothing to compare it against locally — what follows is this building's own mix of strengths and weak spots.

The clearest strength is graduation: 93.2% of students graduate, above the district's 81.7% and the state's 83.0%. Academics are a much harder story. Statewide, the school ranked 270th of 271 Oregon high schools in 2025–2026 with 0 stars — the 0th percentile — and its percentile has slid steadily over three years, from 16 to 7 to 0. Chronic absenteeism stands at 39.4%, worse than the district (38.1%) and the state (33.5%), meaning roughly two in five students miss enough school to be chronically absent.

Test results trail state norms in every subject. All-grades English language arts proficiency is 15.7% versus 43.8% statewide, math is 13.3% versus 32.9%, and science is under 5%. Grade-level results swing widely: 7th grade ELA is the high point at 34.0% and 7th grade math is 23.4%, while 8th grade ELA and 11th grade math both fall under 5% (suppressed figures are upper bounds, not zeros). The school spends $17,973 per student with a 13.5:1 student-teacher ratio, and 81.19% of students qualify for free or reduced-price lunch — so funding and class size do not appear to be the limiting factors.
