Summary:
Broadlands has one listed school, Heritage High School, serving grades 9–12 and enrolling 121 students, so there is no local school-to-school comparison. Graduation was 100% in 2025–26, 10 points above Illinois, while chronic absenteeism was 25%, 2 points above the state. The most important academic takeaway is that results vary sharply by grade: ninth-grade math was below the state, while tenth-grade math was well above it.
Heritage High School’s strongest current results were in ELA: it outperformed Illinois by 16 points in grade 9 and 17 points in grade 10 in 2025–26. Science was also above the state, by 5 points in grade 9 and 14 points in grade 10. Math was the exception: grade 9 was 10 points below Illinois, but grade 10 was 14 points above. Across the two grades, Heritage’s average advantage was largest in ELA (17 points), followed by science (9 points); its math average was 2 points higher, masking the sharp difference between grades.
Recent changes were mixed rather than a steady rise: from 2024–25 to 2025–26, grade 10 improved by 21 points in ELA, 25 in math, and 8 in science, while grade 9 fell by 6, 14, and 23 points, respectively. Grade 9 science’s state lead narrowed from 25 points to 5. SchoolDigger’s ranking rose from 481 of 697 schools, at the 31st percentile with 2 stars in 2023–24, to 124 of 620, at the 80th percentile with 4 stars in 2025–26. Other context includes a 10.7 student-teacher ratio in 2024–25 and 48% free/reduced lunch eligible in 2024–25. The 2025–26 ACT school results were suppressed, so they cannot be compared with Illinois.
