Summary:
Zip code 61616 has one elementary school, Peoria Heights Grade School, serving pre-K through grade 8 and enrolling 488 students. With no other school in the area for comparison, state results provide the clearest benchmark: in 2025–2026, the school’s all-grades English language arts proficiency was 47%, compared with 56% statewide, while math was 17% versus 40%. The most important concern is math, where the school trailed the state by 22 percentage points.
Peoria Heights Grade School shows both a standout and a substantial grade-level weakness. Fifth-grade ELA proficiency was 65%, 10 points above the state’s 55%, and fifth-grade science was 52%, 5 points above the state’s 48%. By contrast, eighth-grade ELA was 33%, 30 points below the state’s 63%; third-grade ELA was 32%, 16 points below the state’s 48%. Results vary considerably by grade, so the all-grades ELA figure does not describe every student’s experience equally well.
Results improved over the two reported years, but the change was more pronounced in ELA than in math: school ELA rose 9 points, narrowing its state gap by 6 points, while math rose 2 points and narrowed its gap by just 1 point. Fifth-grade science also climbed sharply, from 11% in 2024–2025 to 52% in 2025–2026. SchoolDigger’s ranking percentile moved from 34 in 2023–2024 to 30, then 36 in 2025–2026, a net gain of 2 percentile points. Other context includes a student-teacher ratio of 13.1 and 66% free/reduced lunch eligible in 2024–2025; chronic absenteeism was 21% in 2025–2026, below the state’s 24%. Because this is the only school in the list, the figures cannot show how it compares with nearby schools or explain what accounts for its results.
