Summary:

ZIP code 91791 includes three high schools in West Covina Unified, all serving grades 9–12: West Covina High, Mt. SAC Early College Academy at West Covina, and Coronado High (Continuation). In 2025–2026, the schools’ average proficiency was 46% in English language arts (ELA), 19% in math, and 29% in science, compared with state results of 49%, 38%, and 36%. The most important area-wide finding is that math is the clearest shared challenge: even the top-performing school scored below the state in math.

Mt. SAC Early College Academy at West Covina stands out at the top, with 83% proficient in ELA, 29% in math, and 57% in science; it exceeds the state in ELA and science. Coronado High (Continuation) is lowest in all three subjects, at 7% in ELA, 4% in math, and 2% in science. The gap between these schools is 75 percentage points in ELA, 26 in math, and 55 in science. West Covina High falls between them; its ELA result, 48.9%, is close to the state’s 49.3%, while its math and science results are 23% and 29%.

Recent results are mixed: from 2024–2025 to 2025–2026, the Academy rose 14 percentage points in ELA and 5 in science but fell 7 in math; West Covina High declined in all three subjects, while Coronado also declined. The group average moved farther below the state in every subject, with the math gap widening from 14 to 20 percentage points. SchoolDigger ranks the Academy at the 81st percentile (4 stars), West Covina High at the 49th (2 stars), and Coronado at the 5th (0 stars). Reported student–teacher ratios are 21.4 at the first two schools and 9.6 at Coronado. For 2024–2025, free/reduced lunch eligible shares were 66%, 82%, and 90%, respectively; these figures offer context, not an explanation for school results.
