Summary:

ZIP code 95966 has two public high schools, Las Plumas High and Oroville High, and both serve grades 9–12. Their 2025–2026 results show an uneven picture: one school is near the state in ELA and science, while both schools lag in math. The biggest shared concern is math: the schools’ average was 19% proficient, compared with 38% statewide, a gap of 20 percentage points.

Oroville High stands out at the top, leading Las Plumas High by 15 points in ELA (49% versus 34%), 7 points in math (22% versus 15%), and 13 points in science (35% versus 22%). Oroville was essentially at the state level in ELA (49.4% versus 49.3%) and about 1 point below in science, but remained 16 points below in math. Las Plumas was below the state in all three subjects, with its largest shortfall in math at 15% proficient versus 38% statewide.

Recent changes and other school measures offer useful context but do not point to a single explanation for the results. From 2024–2025 to 2025–2026, Oroville improved by 2 points in ELA, 7 in math, and 6 in science; Las Plumas gained 1 point in ELA and 1 in math but fell 5 points in science. SchoolDigger rankings also moved in opposite directions: Oroville rose from the 39th to the 52nd percentile between 2023–2024 and 2025–2026, while Las Plumas fell from the 48th to the 31st. Las Plumas is larger, with 1,265 students versus 872, and the schools’ 2024–2025 student-teacher ratios were similar at 19.3 and 19.5. Both report free/reduced lunch eligible for 2024–2025: 75% at Las Plumas and 82% at Oroville. These are observations, not causes of achievement differences.
