Summary
Dunlap High School serves grades 9–12 and enrolls 1,420 students in the Dunlap community, in the Peoria area. It belongs to Dunlap CUSD 323, which SchoolDigger rates at the 92nd percentile statewide and gives five stars. The most important takeaway is that the school’s 2025–2026 results are strong across the board: it leads nearby high schools in every reported same-grade test comparison and is substantially above state proficiency levels.
Compared with the state, the school’s 11th-grade ACT proficiency was 77% in ELA, 71% in math and 77% in science, versus 50%, 40% and 48% statewide. Math is its strongest subject relative to the state; ELA is its weakest, though still well above state results. It also leads the nearby schools in reported same-grade results: for example, grade 10 ELA was 80% at Dunlap versus 68% at Princeville High School, the next-highest nearby result. Graduation is another strength: 96% at Dunlap, compared with 90% statewide and 82.2%–94.7% at nearby high schools with data. Chronic absenteeism was 11%, below the state’s 24%.
Recent results are mixed rather than uniformly rising: grade 10 ELA improved from 78% to 80%, while grade 9 ELA fell from 87% to 80%; grade 10 math also improved, and grade 9 math rose slightly. SchoolDigger ranks Dunlap 28th of 620 Illinois schools, at the 95th percentile, with five stars for 2025–2026. Its 2024–2025 student-teacher ratio was 18.3, higher than three of the four nearby high schools; its 19% free/reduced lunch eligible figure that year was the lowest among those peers. SchoolDigger’s measured-effectiveness ranking for Multi-racial Students was at the 48th percentile, down from 77th the prior year, notably below the school’s overall standing. For Disabled Students, the ranking was at the 85th percentile in 2025–2026, up from the 39th percentile in 2023–2024. These group rankings and the changing test formats make it difficult to draw one long-term conclusion across every subject and student group.
