Summary:
ZIP code 61734 has one elementary school, Delavan Elementary School, serving prekindergarten through sixth grade and enrolling 191 students. With no other school in the list, families can compare Delavan with state and district figures, but not with nearby school peers. In 2025–2026, its all-grades proficiency was 50% in English language arts (ELA) and 35% in math, below Illinois’s 56% and 40%, respectively. The most important takeaway is that both subjects improved substantially, but Delavan’s latest all-grades results remain below state figures.
Delavan’s strongest academic comparison is fifth-grade science: 50% of students were proficient, 3 points above the state’s 48%. Attendance is another bright spot: chronic absenteeism was 14%, compared with 16% in Delavan CUSD 703 and 24% statewide. Results vary by grade, however: fourth-grade ELA was 2 points above the state, while fifth- and sixth-grade ELA were 9 points below; in math, sixth grade was 4 points above the state, while fourth grade was 4 points below. There is no second local school to identify as a top or bottom performer.
Scores improved from 2024–2025 to 2025–2026: ELA rose 9 points, compared with a 3-point state increase, and math rose 10 points, compared with 1 point statewide. Fifth-grade science climbed 11 points, versus 7 points statewide, moving from slightly below the state to above it. SchoolDigger ranks Delavan 1,018th of 1,737 schools, at the 41st percentile with 2 stars; its percentile rank rose 8 points from 2023–2024, but remains below the statewide midpoint. Context measures include a student–teacher ratio of 8.9 in 2024–2025 and 38% free/reduced lunch eligible in 2024–2025; these figures do not establish why academic or attendance results differ.
