Summary:
These eight high schools in Corona-Norco Unified serve grades 9–12, with enrollments ranging from 162 to 4,353. Averaged equally across schools, 2025–2026 proficiency was 53% in ELA and 37% in science, slightly above California’s 49% and 36%; math averaged 30%, below the state’s 38%. The central takeaway is that these averages mask major differences from one school to another.
John F. Kennedy Middle College High leads all three subjects, with 94% proficiency in ELA, 58% in math, and 85% in science. Its next-highest competitors, Eleanor Roosevelt High, scored 74%, 56%, and 58%, respectively; Kennedy’s leads were 19, 2, and 28 percentage points. At the other end, Orange Grove High had the lowest scores—2% in ELA and 0% in math and science—while Lee V. Pollard High was next-lowest at 11%, 1%, and 1%. Orange Grove was below the state by 48 ELA points, 38 math points, and 36 science points.
Recent changes vary by school: from 2024–2025 to 2025–2026, Roosevelt and Centennial High improved in all three subjects, while Santiago High and Norco High declined in all three. The eight-school ELA average fell about 3 points and the math average was nearly unchanged; science rose about 2 points, but the state improved faster, narrowing the group’s science lead. SchoolDigger’s 2025–2026 rankings place Kennedy at 47 and Roosevelt at 209; both improved their rank since 2023–2024. Staffing and income figures don’t follow a simple score pattern: Kennedy has the highest student-teacher ratio, 29, and the lowest free/reduced lunch eligible share, 59% in 2024–2025; Orange Grove has a ratio of 11 and an eligible share of 93%. These are contextual differences, not explanations for the results.
