Summary:
ZIP code 97056 in Scappoose, Oregon contains exactly one public high school — Scappoose High School, serving grades 9–12 with 709 students as part of Scappoose School District 1J — so the most useful comparison is this school against its own district and against Oregon as a whole.
The school's recent trajectory is the biggest thing to know. Scappoose High ranked 24th of 268 Oregon high schools in 2023-2024 (91st percentile, 5 stars), then fell to 178th of 270 in 2024-2025 and 255th of 271 in 2025-2026 — the bottom 6% of the state, with zero stars. Current test scores agree with that slide: for 2025-2026, 11th graders scored 17.2% proficient in English language arts (state: 46.0%), 8.1% in mathematics (state: 22.9%) and 17.1% in science (state: 33.8%). Math is the deepest weakness — about 35% of the state rate at 11th grade. Note that at the high school level, OSAS tests are given in grade 11 only, so the school's "all grades" and "11th grade" figures are the same students.
The paradox parents should sit with: 95.1% of students graduated in 2024-2025, well above the district's 93.4% and the state's 83.0%, and chronic absenteeism was 29.3% — better than the state's 33.5%. Per-student spending was $18,365, free/reduced lunch was 28.35%, and the student-teacher ratio was 21.2, which is high for a high school. In short, students are showing up and graduating at strong rates, while the school's current juniors test near the bottom of Oregon — and the district's all-grades proficiency (ELA 51.4%, math 39.6%) is far above its own 11th-grade results, suggesting the drop-off happens between middle and high school.
