Summary:
Deerfield School District 109 has six schools—four elementary and two middle schools, with no high schools—and enrollment ranges from 424 to 477 students. Across the six schools, average 2025–2026 proficiency was 84% in ELA and 73% in math, compared with state all-grades figures of 56% and 40%. These state comparisons are not matched to the schools’ grade spans, but every listed school-grade result is above its corresponding state figure. The most important takeaway is that strong results are shared across the schools, with the group’s largest advantage over the state in math: 34 percentage points, compared with 28 points in ELA.
South Park Elementary School leads the elementary schools in both ELA (89%) and math (80%); the elementary lows are Kipling Elementary School in ELA (79%) and Wilmot Elementary School in math (68%), gaps of 10 and 13 points. Among middle schools, Charles J Caruso Middle School leads in ELA (91%) and math (77%), ahead of Alan B Shepard Middle School by 5 points in each. Science leaders differ by grade: Walden Elementary School leads fifth grade at 78%, while Caruso leads eighth grade at 87%.
Recent results are mixed: the six-school ELA average rose from 83% to 84% from 2024–2025 to 2025–2026, while math fell from 76% to 73%. ELA improved at three schools, and math declined at four; Wilmot and Kipling had the largest math drops, about 7 and 6 points. Science improved at every school, with Walden gaining 25 points in fifth grade. SchoolDigger ranks Caruso 25th of 1,126 middle schools (98th percentile) and South Park 62nd of 1,737 elementary schools (96th percentile). Chronic absenteeism averaged 7%, versus 24% statewide. Student–teacher ratios range from 8.9 at Caruso to 12.0 at South Park; reported free/reduced lunch eligible shares were 1.0% to 2.4% in 2021–2022. These figures provide context but do not neatly track school results.
