Summary

Oak Elementary School serves 446 students in prekindergarten through fifth grade in Hinsdale, within Hinsdale CCSD 181. Its latest reported results are exceptional: 94% of students were proficient in English Language Arts (ELA) and 94% in math in 2025–2026. The most important finding is that Oak had the highest reported all-grades ELA and math proficiency among nearby schools with comparable results.

Oak’s results also exceed district and state levels: ELA proficiency is 5 percentage points above the district and 38 above the state, while math is 10 points above the district and 55 above the state. Among five nearby same-district schools with results in both subjects, Oak is 4 points above their average in ELA and 6 points above it in math. It does not lead every comparison: The Lane Elementary School is ahead in third- and fourth-grade ELA, and Madison Elementary School leads fifth-grade ELA and science. Oak’s chronic absenteeism was 6% in 2025–2026, below the district’s 7% and state’s 24%, though Madison and Monroe Elementary School had lower rates.

Oak’s scores remain very high, despite easing from their 2024–2025 peaks: ELA fell 2 percentage points and math fell 1 point. Across the three reported years, ELA rose 5 points overall and math rose 2, while the state made gains that narrowed Oak’s lead. SchoolDigger ranks Oak 8th of 1,737 schools statewide, in the 100th percentile with 5 stars; it has stayed in the 100th percentile in each reported year since 2020–2021. One contrast is its 13.7 students per teacher in 2024–2025, the highest reported ratio among nearby schools with data. Oak reported 0.8% free/reduced lunch eligible in 2021–2022, compared with 0.7% at nearby Madison and John Laidlaw Elementary School that year; these are contextual observations, not explanations for its results.
