Summary:
Gridley’s middle-school list has one school, EPG Middle School, serving grades 5–8 with 345 students. With no second school in the list, families can compare its results with Illinois and look at differences among grades, but not compare local schools with one another. In 2025–2026, EPG was above the state in both all-grades subjects, with its clearest advantage in English language arts (ELA): 69% of students met expectations, compared with 56% statewide, a 13-point lead.
Results vary by grade, with 5th-grade science the strongest standout and 5th-grade math the clearest concern. In science, 70% of EPG fifth-graders met expectations versus 48% statewide, a 22-point advantage; the grade 8 science lead was smaller, at 57% versus 52%, or 5 points. In math, fifth grade was 31% versus 36% statewide, 5 points below, while sixth grade was 51% versus 36%, 15 points above. ELA was above the state in every tested grade, though the lead ranged from 2 points in grade 8 to 22 points in grade 5.
EPG’s ELA advantage grew between 2024–2025 and 2025–2026: its result rose from 62% to 69%, while the state’s rose from 53% to 56%, widening the gap from 9 to 13 points. Math results changed little relative to the state: EPG rose from 43% to 44%, and its lead stayed around 5 points. SchoolDigger’s rating moved from 4 stars and the 70th percentile in 2023–2024 to 4 stars and the 74th percentile in 2024–2025, then 3 stars and the 67th percentile in 2025–2026. Other context includes an 8% chronic absenteeism rate, 13.3 students per teacher in 2024–2025, and 35% free/reduced lunch eligible in 2024–2025.
