Summary:
Zip code 60162 has two schools: Hillside Elementary School, serving pre-K through grade 8, and Proviso West High School, serving grades 9–12; no middle school is listed. The schools serve different grades and take different tests, so their scores are not a fair direct basis for ranking one against the other. The clearest overall concern is at Proviso West: all nine reported subject-and-grade results were below state rates by 31 to 38 percentage points in 2025–2026.

Hillside fifth-grade science was closer to the state: 45% proficient versus 48%.
