Summary:
Zip code 60181 has one listed high school, Willowbrook High School, serving grades 9–12 with 1,983 students, so the available figures describe one school rather than a choice among local high schools. In 2025–2026, Willowbrook scored above Illinois in seven of nine reported subject-and-grade comparisons, and its clearest overall strength is that it exceeded DuPage HSD 88 in all nine.
Willowbrook’s strongest result against the state was grade 10 English language arts: 58% proficient, compared with 54% statewide, a 4-point advantage. Its weakest was grade 9 science, with 42% proficient versus 47% statewide, a 5-point shortfall; grade 9 English language arts was also below the state, by 2 points. Even in those two areas, the school was above its district: by 4 points in grade 9 English language arts and 1 point in grade 9 science.
Test results improved on average across the nine matching comparisons from 2024–2025 to 2025–2026, rising about 1 point while state results were essentially flat, but the pattern varied: grade 9 science fell 6 points and grade 9 English language arts fell 3, while grade 9 math rose 5. SchoolDigger’s ranking percentile also declined, from the 76th percentile in 2023–2024 to the 61st in 2025–2026; its rank changed from 167 of 697 to 239 of 620. Other context is mixed: the 2025–2026 graduation rate was 91%, 1 point above the state, while chronic absenteeism was 33%, 9 points higher.
