Summary
Glen A. Wilson High serves 1,456 students in grades 9–12 in Hacienda Heights, California, as part of Hacienda la Puente Unified. Its strong academic results are matched by favorable completion and attendance figures: in 2025–2026, 99% of students graduated, compared with 97% in the district and 88% statewide, while chronic absenteeism was 14%, below the district’s 17% and the state’s 18%. Most notably, the school led five nearby comprehensive high schools in both English language arts and math.
ELA and math are the school’s clearest strengths against local and statewide results: in 2025–2026, 74% met the ELA standard and 58% met the math standard, exceeding state results by 25 and 19 percentage points, respectively, and district results by 24 and 17 points. It also led the nearby schools by 13 points in ELA and 14 in math over John A. Rowland High, the next-highest school in those subjects. Science was strong compared with the state and district—48%, or 12 and 13 points higher—but ranked second locally behind John A. Rowland. The all-grades science result also hides a sharp senior-year dip: 11th-grade proficiency was 49%, while 12th-grade proficiency was 9%, below the state’s 33% and the district’s 10%.
Scores remain above state results, but the school’s advantage has narrowed as its scores fell from 2022–2023 to 2025–2026: ELA declined by 5 percentage points, math by 7, and science by 8. SchoolDigger ranks the school 265th of 2,137 statewide, at the 88th percentile with 4 stars; the district is at the 48th percentile with 2 stars. The 2024–2025 student-teacher ratio was 24.3, tied for the highest among six nearby comprehensive high schools. In that same year, 65% of students were free/reduced lunch eligible, the lowest share among those six schools. SchoolDigger’s subgroup rankings show lower relative results for Asian students (55th percentile) and White students (50th) than the school’s overall 88th percentile; the Asian-student ranking fell from the 78th percentile in 2023–2024.
