Summary:
ZIP code 61373 has one listed school, Waltham Elementary School, serving prekindergarten through grade 8, with 246 students. With no other listed school in the area, families can compare its results with Illinois figures rather than with a local school. The clearest overall finding is that Waltham’s 2025–26 all-grade results were above the state average in both subjects: 75% in English language arts (ELA) versus 56% statewide, and 50% in math versus 40%.
Waltham’s strongest reported grade-level results were in grade 8 ELA, at 95% compared with 63% statewide, and grade 3 math, at 74% compared with 49%. Its science results were also above the state in grades 5 and 8: 60% versus 48% and 76% versus 52%, respectively. Grade 5 is the main weak spot: ELA was 50% versus 55% statewide, and math was 33% versus 36%. Results for grades 7 and 8 math are not available for comparison because the state suppressed them.
Waltham’s all-grade results and its advantage over the state increased from 2024–25 to 2025–26: ELA rose from 71% to 75%, widening its lead from 17 to 18 percentage points; math rose from 46% to 50%, widening its lead from 7 to 10 points. SchoolDigger’s statewide percentile for the school rose from 58 in 2023–24 to 69 in 2025–26, while its reported star rating stayed at 3. Chronic absenteeism was 2% at Waltham and in the district, compared with 24% statewide. For context, the school’s student-teacher ratio was 10.4 in 2024–25, and 19% of students were free/reduced lunch eligible in 2021–22. These grade-level results vary considerably within the school, and the low-income figure is from an earlier year than the enrollment and ratio data.
