Summary
Stone Bank Elementary is a small public PK–8 school in Oconomowoc, WI, serving 241 students in the Stone Bank School District, and it is the smallest school in its nearby comparison group. Statewide, it is elite: 19th of 1,039 Wisconsin schools in 2025–2026, the 98th percentile with 5 stars, while its district ranked 12th of 432. Its rank has climbed steadily, from the 90th percentile in 2020–2021 to the 98th in 2024–2025 and 2025–2026. Locally, though, the competition is unusually tough — the Swallow School District ranks 1st, Merton Community School District 3rd, Lake Country School District 7th, and North Lake School District 10th, putting Stone Bank fifth among nearby districts.
Test results beat state averages in every subject and grade tested. Averaged across grades, ELA was about 81.4%, math about 84.3%, social studies about 83.5%, and science about 80.1%, while state figures sit in the low-to-mid 50s for ELA and math, near 65% for social studies, and near 53% for science. Grades 3–4 are a particular strength, with math around 90.2% — second only to Lake Country School locally. Grades 5–8 are more mixed: ELA averages about 80.7% and math about 81.3%, trailing Swallow Elementary and Lake Country but roughly matching North Lake Elementary. Resources are the highest in the area: an 11.8:1 student-teacher ratio and $16,910 per-student spending.
Chronic absenteeism is the clearest local weakness: 12.1% in 2024–2025, below Wisconsin's 17.3% but higher than every nearby school listed, including Swallow at 2.5% and Lake Country at 11.5%, and up from 7.2% the year before even as free/reduced lunch declined. The dropout rate was 0.0%. Subgroup results are strong where data exist — female students ranked 21st of 986 and male students 35th of 989 in 2025–2026, and historical low-income and special education ranks were also high, though newer data for those groups isn't available. Overall, this is a top-2% school with standout lower grades, positive momentum, and two areas to watch: middle-school relative performance and attendance.
