Summary

Adeline Montessori School Inc is a PK–8 school in Oconomowoc, WI, with 211 students, located in a generally high-performing suburban area where many nearby public schools rank among the top in Wisconsin.

In 2025–2026, Adeline ranked 453rd of 1,039 schools statewide—56th percentile, 3 stars—and its district, Adeline Montessori School Inc, ranked 181st of 432 districts. That is a big rebound from 2024–2025, when the school was in the 10th percentile, and it shows how volatile results can be at a small school with 211 students. Compared with nearby schools, Adeline is middling: Lake Country School is in the 98th percentile, Park Lawn Elementary in the 97th, and Summit Elementary in the 96th, while only Dousman Elementary ranks lower than Adeline in the latest comparison set. Adeline’s clearest academic weakness is early-grade math: in 2025–2026, 3rd grade math proficiency was 0% and 4th grade was 11.11%, far below the state and every nearby school. By contrast, 4th grade science and social studies were 88.89%, and 8th grade ELA was 85.71%, nearly matching Lake Country School’s 85.37%.

Other factors set Adeline apart: it has the lowest free/reduced lunch rate (1.42%) and the lowest student-teacher ratio (11.4) in the comparison set, yet math outcomes still lag. Chronic absenteeism improved from 27.6% in 2022–2023 to 11.4% in 2024–2025, now better than the state average but still higher than several nearby schools. The reported dropout rate is a red flag at 12.1%, far above the state’s 1.1%, and should be verified because Adeline is a PK–8 school. In the latest available subgroup data from 2024–2025, no measured subgroup ranked above the 22nd percentile; 2025–2026 subgroup results are not yet available. The big question is whether the 2025–2026 rebound in ELA, science, and social studies is sustainable while math remains a consistent challenge.
