Summary:
Zip code 97830 has one school, Fossil Charter School, an alternative K–12 school in Fossil, Oregon, and the only school in Fossil School District 21J, so school and district figures match wherever both are reported.

For parents, the headline is strong academic performance relative to Oregon. In 2025–2026 OSAS results, all-grade proficiency is 64.7% in English language arts, 53.4% in mathematics, and 52.9% in science, compared with state rates of 43.8%, 32.9%, and 30.6%—gaps of +20.9, +20.5, and +22.3 percentage points. The 2024–2025 graduation rate is 100.0%, versus 83.0% statewide. Grade-level results also stand out: 7th grade has 76.7% ELA and 62.2% math proficiency, the highest reported grade-level values and +31.4 and +28.9 points above the state. Other strong results include 4th-grade ELA at 68.4%, 8th-grade ELA at 65.0%, and 3rd-grade math at 59.3%.
Some data is limited. All 11th-grade OSAS scores are suppressed with a —, so high school proficiency is unknown, though the graduation rate is a positive completion signal. Chronic absenteeism is reported as 7.5% for the school in 2021–2022, while the state figure is 33.5% in 2024–2025; because the years differ and the school’s 2024–2025 value is not reported, this is not a direct comparison. The student-teacher ratio is high at 43.9, per-student spending is $10,643, and free/reduced-lunch data is not reported. Overall, the only school in zip 97830 posts notably strong reported outcomes, with caveats around suppressed 11th-grade tests, absenteeism years, and missing poverty context.
