Summary:
ZIP code 61489 has one elementary school, Williamsfield Elementary School, serving pre-K through grade 4 and enrolling 128 students in Williamsfield CUSD 210. As the only school listed, it offers no peer comparison, and suppressed grade 3 and grade 4 math results are unknown. The most important finding is a sharp drop in the school’s all-grades test results: after scoring well above the state in 2024–2025, it was below the state in both subjects in 2025–2026.
There is no meaningful local top or bottom, but grade 4 ELA stands out as a strength: 81% of students were proficient in 2025–2026, compared with 56% statewide, a 26-point advantage, and the same 81% in the district. Across all grades, however, the school scored 50% in ELA and 37% in math, versus 56% and 40% statewide. It was also 15 points below the district in ELA and 1 point below in math. Attendance is a positive feature: chronic absenteeism was 5%, compared with 14% in the district and 24% statewide.
Results changed substantially from one year to the next. ELA proficiency fell 32 points, from 82% in 2024–2025 to 50% in 2025–2026, while the state rate rose 3 points; math fell 39 points, from 76% to 37%, while the state rose 1 point. SchoolDigger ranked Williamsfield Elementary School at the 90th percentile in 2024–2025, compared with the 65th percentile in 2023–2024 and 79th in 2022–2023; those rankings are not test-score percentages, and no 2025–2026 rank is provided. Other context includes a 12.9 student–teacher ratio and 33% free/reduced lunch eligible in 2024–2025. The one-year score drop is large, so later results will help show whether it continues.
