Summary:
ZIP code 91763 has 10 listed schools—seven elementary, two middle and one high school—serving students from elementary through high school. In 2025–2026, the unweighted school averages were 51% proficient in English language arts (ELA), 40% in math and 32% in science, compared with state results of 49%, 38% and 36%. The most important takeaway is that results vary widely by school and subject: science proficiency ranged from 14% to 66%.
Monte Vista Elementary led ELA with 65% proficient, 16 percentage points above the state; Lehigh Elementary had the lowest ELA result, 35%, 14 points below the state.

Among the same-grade-span middle schools, Serrano Middle exceeded Vernon Middle in all three subjects, with all-grades gaps of 11 points in ELA, 15 in math and 4 in science.
From 2024–2025 to 2025–2026, the school-group average was essentially unchanged in ELA, rose 2 points in math and rose 8 in science; the science gap below the state narrowed from 9 points to 4, though gains differed among schools. SchoolDigger’s rankings put Buena Vista at the 79th percentile and Monte Vista at the 78th, while Kingsley was at the 29th. For added context, the elementary schools’ reported measure was free/reduced lunch eligible for school year 2024–2025: shares ranged from 69% at Buena Vista to 94% at Lehigh, while Monte Vista’s share was 85% despite its top ELA result. Montclair High also shows why subject-level results matter: its ELA proficiency was 64%, but math was 25%.
