Summary:
The four high schools in Covina-Valley Unified serve grades 9–12: three comprehensive schools and one continuation school. Their reported proficiency results for 2025–2026 vary considerably, and Fairvalley’s much lower scores make the overall picture especially uneven. The most important takeaway is that a student’s school is associated with very different reported proficiency levels across this area.
Covina High leads in English and science, with 63% and 38% proficient—about 14 and 2 percentage points above the state, respectively. South Hills High leads in math at 40%, about 1 point above the state and the only school above the state in that subject. Among the comprehensive schools, Northview High has the lowest results in all three subjects: 45% in English, 18% in math, and 22% in science, respectively 4, 20, and 14 points below the state. Fairvalley High (Continuation) is far lower still, at 3% in English and 0% in math and science.
Recent trends also differ by school: from 2024–2025 to 2025–2026, Covina gained 13 points in math and 9 in science, while Northview fell 9 points in English, 6 in math, and 2 in science. South Hills gained 6 points in math but fell 6 in English. SchoolDigger’s statewide percentile ranking rose from 54 to 68 for Covina and from 64 to 68 for South Hills, while Northview fell from 47 to 38 and Fairvalley from 3 to 1. For context, the schools reported a free/reduced lunch eligible measure for 2024–2025: 72% at Covina, 62% at South Hills, 79% at Northview, and 87% at Fairvalley. The comprehensive schools have student-teacher ratios of 20.7 to 22.4; Fairvalley’s is 7.8, with 115 students. Fairvalley’s continuation-school setting and small enrollment make it less directly comparable with the comprehensive schools.
