Summary:
ZIP code 97845, in and around John Day, Oregon, has just one listed high school: Grant Union Junior/Senior High School, a combined junior/senior campus serving grades 7–12 with 206 students, part of John Day School District 3. Because it is the only high school in the area, there are no local peers to compare it with — the most useful benchmarks are the district and the state of Oregon. Its 7–12 structure also means "All Grades" results blend middle school and high school students.
Rankings are the most dramatic story. In 2025–2026 the school ranks 261 of 271, at the 4th percentile with 0 stars. Two years earlier, in 2023–2024, it ranked 20 of 268 — the 93rd percentile with 5 stars — before slipping to 94 of 270, 65th percentile, 3 stars in 2024–2025. Test proficiency is low across the board: all-grade English Language Arts is 8.5%, versus 14.8% in the district and 43.8% statewide; all-grade math is under 5%, versus 11.7% district and 32.9% state; all-grade science is 7%, versus 8.9% district and 30.6% state. Every reported math result — all grades, 11th grade, 7th grade, and 8th grade — is under 5%. The strongest single result is 11th-grade ELA at 18.2%, still well below the state's 46.0%.
Other measures are more encouraging. The graduation rate is 88.9%, above Oregon's 83.0%, and chronic absenteeism is 30.8%, below the state's 33.5%. The school spends $32,214 per student with a 12:1 student-teacher ratio, and 72.33% of students qualify for free or reduced lunch — important context, though the data do not show cause and effect.
