Summary:
Zip code 95966 has 12 schools serving grades K–12: six elementary schools, two middle schools, two high schools, and two alternative schools. Results vary widely, so the schools’ overall averages hide meaningful differences. The most important takeaway is that only Oroville High is above the state average in any all-grades subject—and its ELA result is only slightly higher.
In 2025–2026 all-grades results, Oroville High led ELA at 49% and science at 35%, while Ophir Elementary led math at 32%. Oroville High’s ELA score was 49.4%, just above the state’s 49.3%; the area’s top math and science results remained below state averages. At the other end, The Studios @ Central had the lowest result in all three subjects: 18% ELA, 8% math, and 10% science. The gaps between the highest and lowest schools were 31 points in ELA, 24 in math, and 25 in science. Same-grade comparisons also favor Oroville High: its 11th graders were ahead of Las Plumas High by 15 points in ELA, 7 in math, and 13 in science.
Recent changes are mixed rather than showing a clear area-wide trend: average school results were essentially flat in ELA, up about 1 point in math and 3 in science, while individual schools had larger gains and declines. SchoolDigger rankings also moved in different directions: the percentile rose 13 points at Oroville High and fell 17 at Las Plumas High. The high schools have similar student–teacher ratios—19.5 at Oroville High and 19.3 at Las Plumas High—but their free/reduced lunch eligible measures for 2024–2025 were 82% and 75%, respectively; these are context, not explanations for score differences. Attendance is another consideration: 10 of 12 schools had chronic absenteeism above the state’s 18% rate, while Golden Hills Elementary and Helen M. Wilcox Elementary were below it.
