Yorkville J2 School District

The Yorkville J2 School District serves the Union Grove, Wisconsin area and contains just one school — Yorkville Elementary — which enrolls 465 students in grades PK–8, so although it is classified as an elementary school, it also produces middle-grade Forward Exam results. Because the district has only one school, school-level and district-level results are essentially the same. The district ranks 35th of 432 Wisconsin districts (92nd percentile) with a 5-star rating, while the school ranks 110th of 1,039 schools (89th percentile) with 4 stars — likely a difference in rating methods rather than in performance. For context, 25.38% of students qualify for free or reduced lunch, per-student spending is $14,431, and the student-teacher ratio is 14.4.

Academically, every tested grade and subject in 2025–2026 scored above the state average. Math was the standout: an unweighted average of 81.03 against 53.73 statewide, with grade 7 at 87.72, grade 3 at 87.18, grade 6 at 85.42, and grade 8 at 84.48. Social studies averaged 85.52 versus 65.07 statewide, including fourth grade at 90.00, the highest single result in the data. Science averaged 68.92 versus 52.66, and ELA 67.83 versus 54.04. Across all listed tests, the school's average rose from 70.91 to 75.13 while the state moved only from 54.19 to 55.13, widening the gap from +16.73 to +20.00 points. The school's rank has climbed steadily, from 280th (74th percentile) in 2023–2024 to 201st (81st) in 2024–2025 and 110th (89th) in 2025–2026.

The main area to watch is eighth-grade science, which fell from 77.05 to 60.34, a decline of 16.71 points, though it remained above the state's 51.86. Some ELA grades also softened — third grade from 84.62 to 79.49 and fourth grade from 68.89 to 62.50 — while ELA overall stayed comfortably above state. The only below-state result in the two-year data was fifth-grade ELA in 2024–2025 at 45.45 against 51.26; it rose to 64.44 the following year, and because these are different groups of students rather than the same class tracked over time, the change reflects a new cohort. School climate indicators are strong: chronic absenteeism is 9.7% versus 17.3% statewide, and the dropout rate is 0.8% versus 1.1%.
