Summary

Oak Knoll Alternative is a K–12 alternative school in Glendora, serving 107 students in Charter Oak Unified. Its latest reported results show a mixed academic picture: English language arts (ELA) is a relative strength, while math and science results are lower. The most important academic concern is math, with just 11% of students proficient.

Compared with nearby schools, Oak’s ELA result of 42% was second-highest among six schools with reported scores; it was 7 points below the state and 11 below its district. Math was fourth of six at 11%, 27 points below the state and 31 below the district. Science was fifth of six at 17%, trailing the state by 19 points and the district by 18. Oak’s ELA result was also 7 points above the available nearby-school average, while math was 17 points below its peer average and science was 8 points below. The reported fifth-grade results echo this pattern: ELA was near the state level, while math and science were lower.

Oak has lost ground relative to the state since 2022–2023. ELA proficiency fell 12 points, shifting from 8 points above the state to 7 below; math was nearly unchanged overall, but its state gap widened from 23 to 27 points. Science fell 9 points as its gap widened from 4 to 19. Context matters: the reported student–teacher ratio was 33.2 in 2024–2025, higher than the nearby schools’ reported range of 3.2–29.1. In that same year, 75.7% of students were free/reduced lunch eligible, close to the nearby-school average of 76.4%. SchoolDigger ranks the district—not Oak itself—393rd of 968, at the 59th percentile with 3 stars. The 2025–2026 graduation rate was 100%, though five reported years ranged from 71% to 100%; chronic absenteeism was 27%, above the state’s 18% and district’s 17%.
