Summary:
Chicago Heights School District 170 has 10 schools serving elementary grades K–5 and middle-school grades 6–8 in the Chicago Heights area. In 2025–2026, the school averages were 48% in ELA and 34% in math, compared with state results of 56% and 40%; elementary-school averages were 49% and 36%. The most important finding is the sharp variation among elementary schools: ELA results ranged from 29% at Washington-McKinley Elementary School to 68% at U S Grant Elementary School.
U S Grant Elementary School and Greenbriar Elementary School led elementary ELA with 68% and 67%, respectively—11 and 10 points above the state. Kennedy Elementary School and U S Grant Elementary School tied for the top elementary math result at 47%, 8 points above the state. Greenbriar also led reported grade-5 science at 73%, 26 points above the state result. At the lower end, Washington-McKinley’s ELA was 28 points below the state, while Roosevelt Elementary School had the lowest elementary math result, 27%, or 12 points below the state. Chicago Heights Middle School was below the state in ELA (40% versus 56%), math (17% versus 40%), and grade-8 science (31% versus 52%).
District averages improved from 2024–2025 to 2025–2026—ELA rose 3 points and math 1 point—but the gaps with the state were largely unchanged. SchoolDigger ranks Greenbriar at the 77th percentile with 4 stars, Grant at the 69th percentile with 3 stars, and Kennedy at the 60th percentile with 3 stars; the Middle School’s rank fell from the 30th to the 9th percentile over the three latest years shown. Strong results occur alongside differing reported circumstances: in 2024–2025, Kennedy reported 97% and Grant 95% free/reduced lunch eligible, while Greenbriar reported “All students receive free meals” through Community Eligibility. Greenbriar’s student–teacher ratio was 15.8 and Grant’s was 9.8; these figures do not form a simple pattern with results. These are reported test results and do not explain why schools differ.
