Summary:

Schools in zip code 61734 serve Delavan students from prekindergarten through grade 12 across three schools: Delavan Elementary School, Delavan Junior High School, and Delavan High School. Results show encouraging improvement at the lower schools, while high-school results vary by subject. The most important finding is that the area’s results are uneven: high-school ELA and science stand out, but math remains a concern.

Delavan High School had the strongest state-relative results in 2025–2026: 11th-grade ACT ELA was 71% versus 50% statewide, a 22-point advantage, and science was 57% versus 48%, a 9-point advantage. Its ACT math result was weaker at 31% versus 40% statewide, 8 points below. Among the IAR schools, Delavan Elementary led Delavan Junior High in all-grades ELA, 50% to 48%, and math, 35% to 27%; both schools were below state results in those all-grades comparisons. There are bright spots by grade: Elementary’s fourth-grade ELA and sixth-grade math, and Junior High’s eighth-grade ELA, each exceeded the state. The all-grades IAR results cover different grade spans, so they are not like-grade comparisons.

Elementary and Junior High improved their IAR results from 2024–2025 to 2025–2026: ELA rose 9 points at Elementary and 15 at Junior High, while math rose 10 points and 2 points, respectively. High School’s ACT results moved the other way: from 2024–2025, ELA fell 6 points, science 20, and math 23. SchoolDigger’s ranking percentile increased for Elementary from 33 in 2023–2024 to 41 in 2025–2026; Junior High reached 39 in 2024–2025 after ranking 30 in each of the prior two years. High School’s percentile rose from 47 to 84, then eased to 77. As context, all three schools reported free/reduced lunch eligible in 2024–2025: 38% at Elementary, 36% at Junior High, and 30% at High School. Student-teacher ratios were 8.9, 12.5, and 11.9, respectively. Chronic absenteeism was below the 24% state rate at each school, while High School’s graduation rate was 83% versus 90% statewide.
