Colona School District 190

Colona School District 190 has one school, Colona Grade School, serving prekindergarten through grade 8 and enrolling 371 students. In 2025–2026, the school’s all-grades proficiency was below Illinois in both tested subjects: 44% in English language arts (ELA) versus 56% statewide, a 12-point gap, and 25% in math versus 40%, a 15-point gap. The clearest overall concern is that students’ proficiency trails the state in both subjects, with the math gap 3 points wider.

Within the school, grade 3 is the strongest reported comparison with the state: ELA proficiency was 58% versus 48% in Illinois, and math was 52% versus 49%. ELA results were below the state in every reported grade from 4 through 8, with gaps ranging from 9 points in grade 4 to 24 points in grade 8; grade 8 had the lowest comparison, at 39% versus 63%. Science also varied by grade: grade 5 was 42%, 6 points below Illinois, while grade 8 was 31%, 21 points below. Since this is the district’s only school, there is no meaningful school-to-school ranking within the district.

Recent results show different directions by subject. From 2024–2025 to 2025–2026, ELA rose from 39% to 44%, and its gap with the state narrowed from 14 to 12 points; math slipped from 26% to 25%, while the state rose from 39% to 40%, widening the school’s gap from 13 to 15 points. Grade 5 science also shifted from 6 points above the state to 6 points below, while grade 8 science improved by 7 points and remained 21 points below the state. SchoolDigger’s ranking declined from the 47th percentile in 2023–2024 to the 33rd percentile in 2025–2026, while its rating stayed at 2 stars. As context, the student–teacher ratio was 13.4 in 2024–2025, and 53% of students were free/reduced lunch eligible that year; chronic absenteeism was 17% in 2025–2026, 6 points below the state rate.
