Summary:
Zip code 97378 is home to a single high school — Sheridan High School — a grades 9–12 campus with 211 students in the Sheridan School District 48J in Oregon. Because it is the only high school in the area, there is no local peer school to compare it against, so the most useful benchmarks are its own district and Oregon statewide averages.
Sheridan High School's clearest strength is its graduation rate of 86.4%, which is above both the district (76.1%) and the state (83.0%). The school has also been climbing in statewide ranking over three years: from 263 of 268 (2nd percentile, 0 stars) in 2023–2024, to 241 of 270 (11th percentile, 1 star) in 2024–2025, to 200 of 271 (26th percentile, 1 star) in 2025–2026. That is real upward movement, though the school still sits below the state median. By contrast, the district overall is ranked 53 of 141 (62nd percentile, 3 stars), suggesting the high school is performing below the district's broader profile.
The main concerns are attendance and mathematics. Chronic absenteeism is 49.7% — nearly half the student body — compared with 34.5% in the district and 33.5% statewide. In OSAS testing, only 6.5% of students were proficient in math at both the all-grade and 11th-grade levels, far below the district (24.9% all grades, 30.3% 11th grade) and state (32.9% all grades, 22.9% 11th grade). Eleventh graders also trail in English language arts (36.7% vs. district 54.3% and state 46.0%) and science (29.0% vs. district 44.3% and state 33.8%). Context matters: 87.68% of students qualify for free/reduced lunch, per-student spending is $22,849, and the student-teacher ratio is 21.1.
