Summary:
ZIP code 60515 has eight schools: six elementary schools, one middle school and one high school. The elementary schools’ 2025–2026 results are broadly strong compared with Illinois, though performance varies by school and subject: their average proficiency was 78% in ELA, 71% in math and 72% in fifth-grade science, exceeding state rates by 22, 32 and 24 percentage points, respectively. The most important finding is that all six elementary schools beat the state rate in each of these three measures.
Top results vary by subject: Belle Aire Elementary School led elementary ELA at 82.1%, just ahead of Whittier Elementary School at 82.0%; Pierce Downer Elementary School led math at 79.3%, about 2 points ahead of Belle Aire; and Lester Elementary School led fifth-grade science at 78.3%, about 3 points above Whittier. Henry Puffer School was lowest in all three: 70% in ELA, 57% in math and 67% in science. Its math result was 13 points below the next-lowest school. The sole middle and high schools also scored well above state rates: Herrick Middle School posted 85% ELA and 66% math, while Community High School District 99 - North High School had 75% ELA, 66% math and 71% science on its 11th-grade ACT results.
Across the elementary schools, average ELA rose 4 points and fifth-grade science rose 11 points from 2024–2025 to 2025–2026, while average math slipped by 1 point. Those averages hide different school trends: for example, Puffer’s science increased 26 points, but its math fell 4; Belle Aire’s math fell 5 points even as its ELA rose 3. SchoolDigger ranks North High at the 96th percentile statewide, Herrick at the 94th, and the elementary schools between the 78th and 94th percentiles. Context indicators do not sort schools into a clear performance pattern: Puffer had the lowest listed student-teacher ratio, 10.3 in 2024–2025, and the highest elementary free/reduced lunch eligible share, 21% in 2021–2022; Belle Aire’s share was 17%, while Pierce Downer’s was 5%. These measures offer context, not an explanation for test results; school results also vary by grade and subject.
