Summary:
Gridley’s school list contains one public middle school, EPG Middle School, serving grades 5–8 and 345 students, so parents have no other listed local school to compare it with. In 2025–2026, the school’s all-grade proficiency was above Illinois in both English language arts (ELA) and mathematics: 69% versus 56% in ELA and 44% versus 40% in math. The clearest overall strength is ELA, where the school’s proficiency rate was 13 percentage points above the state.
Because it is the only school in the list, EPG Middle School is technically both the area’s highest- and lowest-scoring school, but that is not a meaningful peer ranking. Its strongest state comparisons were fifth-grade science, at 70% proficient versus 48% statewide, and fifth-grade ELA, at 77% versus 55%. Fifth-grade mathematics was the standout weakness: 31% were proficient, 5 percentage points below the state’s 36%. Math results were above state rates in grades 6–8, so the fifth-grade result is an exception to an otherwise stronger pattern.
Results changed unevenly over time: all-grade ELA rose 7 percentage points from 2024–2025 to 2025–2026, compared with a 3-point state increase, while math rose 1 point at the school and statewide. SchoolDigger reports a recent ranking decline: 67th percentile and 3 stars in 2025–2026, compared with the 74th percentile and 4 stars the year before. Chronic absenteeism was 8% in 2025–2026, versus 24% statewide. For context, the school’s student-teacher ratio was 13.3, and 35% of students were free/reduced lunch eligible in 2024–2025; these figures describe the school but do not explain its test results. With only one school listed, the figures cannot show how it compares with similar schools.
