Summary:
The city of Sullivan, Wisconsin is served by one public school: Sullivan Elementary, an elementary school serving grades PK–5 with 144 students, part of the Jefferson School District. No middle, high, or alternative schools appear in this dataset, so the city's public-school profile is entirely elementary; older students presumably attend schools elsewhere in the district.
Sullivan Elementary's statewide rank has climbed sharply — from 532 of 1061 (50th percentile, 2 stars) in 2023–2024, to 343 of 1044 (67th percentile, 3 stars) in 2024–2025, to 218 of 1039 (79th percentile, 4 stars) in 2025–2026, a gain of 314 rank positions, 29 percentile points and 2 stars. In 2025–2026 the school outperformed both its district and the state in all eight listed Forward Exam results, led by Grade 4 Social Studies (88.46%), Grade 3 Mathematics (73.68%), Grade 4 Mathematics (73.08%) and Grade 4 Science (69.23%). Margins over the district ranged from 2.88 points in Grade 4 ELA to 15.79 points in Grade 4 Mathematics, and over the state from 3.51 to 22.95 points. Simple unweighted averages across listed tests were 69.0 school / 59.5 district / 54.7 state in 2025–2026, up from 63.4 / 58.9 / 54.0 the year before.
Two previously weak math results rebounded: Grade 4 Mathematics rose 28.64 points to 73.08%, and Grade 5 Mathematics rose 11.90 points to 61.90%, both now above district and state. Grade 3 Mathematics slipped 18.32 points from 92.00% but still beat the district's 60.76% and the state's 54.75%. The lowest proficiency result improved from 44.44% to 57.14%. Chronic absenteeism is 5.3%, versus 16.3% in the district and 17.3% statewide. Other 2024–2025 figures include 23.61% free/reduced lunch, $14,637 per-student spending and a 12.5 student-teacher ratio. With just 144 students, grade-level cohorts are small and year-to-year swings can be volatile.
