Summary:
The Adeline Montessori School Inc district in Oconomowoc, Wisconsin (53066) contains just one elementary school: Adeline Montessori School Inc, which serves grades PK–8 to 211 students. Because it is a single-school district, district-level figures and school-level figures are the same, so every number below describes the one school your child would attend.
The biggest story is a sharp turnaround. The school rose from 938th of 1044 schools in 2024–25 (1 star, 10th percentile) to 453rd of 1039 in 2025–26 (3 stars, 56th percentile), a jump of 485 places and two stars. Reading, science, and social studies are now strengths: 8th grade ELA scored 85.71% versus the state's 54.38%, 4th grade ELA 77.78% versus 53.87%, 4th grade science 88.89% versus 53.46%, and 4th grade social studies 88.89% versus 65.51%. Eighth grade is the strongest band, with every reported subject above state average. Math is the clear weak spot, averaging roughly 25% proficient in both years against a state average near 54%. Third grade math came in at 0% and 4th grade math at 11.11%, though 8th grade math (57.14%) edged above the state's 53.67%. Fourth grade stands out for its split profile—well above state in ELA, science, and social studies, but far below in math.
Other measures look favorable: chronic absenteeism is 11.4% versus 17.3% statewide, free/reduced lunch is just 1.42%, and the student-teacher ratio is 11.4. One oddity is the reported 2024–25 dropout rate of 12.1% against Wisconsin's 1.1%—unusual for a PK–8 school and possibly a reporting artifact, but worth asking about. Because grade sizes are small, percentages like 88.89% and 11.11% can swing widely from year to year, so treat single-year scores as directional rather than precise.
