Stone Bank Elementary, Oconomowoc WI

Original Research by School Decision on Stone Bank Elementary

Stone Bank Elementary serves students from pre-kindergarten through eighth grade in a single building, part of the Stone Bank School District, a small district whose address places it in Oconomowoc but whose attendance area draws from the surrounding rural and exurban parts of Waukesha County. The school is a regular public school with no charter or magnet designation.

The student body is overwhelmingly white, with a very small share of students who identify as Hispanic, Black, Asian, or multiracial. A modest share of students qualify for free or reduced-price lunch, a figure that is low relative to many other schools. The enrollment is small for a PK-8 campus, with fewer than three hundred students, and class sizes appear to be moderate, ranging from roughly twenty to the mid-forties in the upper grades. There is no high school grade band here, so there is no graduation rate to report.

Academically, the school performs well on Wisconsin’s Forward assessments. Proficiency rates in reading and math are strong at most grade levels, with several grades hitting rates well above the state average. In math, for instance, proficiency is very high in grades three and five, and solidly above the midpoint in the other tested grades. In English language arts, rates are consistently strong, with every grade performing at or above the mid-seventies and eighth grade reaching a particularly high mark. Science results are mixed: fourth grade posts a solid rate, but eighth grade trails noticeably behind. Social studies scores are strong at both test points. The school’s overall proficiency index places it above the midpoint among districts in Waukesha County, a county known for having a number of high-performing districts. A parent should be aware that while the school’s results are positive for the county, a few grade-level scores — particularly eighth-grade science and middle school math — are lower than the school’s own strongest grades, and a family may want to look into how the school addresses those areas directly.

The school itself is the only school in the Stone Bank School District, which is a very small district. The district brief turned up no major recent changes that passed the four-year threshold, so the picture is one of continuity. The school’s setting is rural and semi-rural, located on a county highway outside the main downtown of Oconomowoc. Oconomowoc itself is a city that has seen a historic downtown revival and is home to Wisconsin’s largest master-planned development on its outskirts, signaling growth. Healthcare is a major local employer. The city is car-dependent beyond its walkable downtown core. A recent municipal merger in 2025 between the Village of Lac La Belle and the Town of Oconomowoc landlocked the city’s borders, which may shape long-term growth patterns.

For a family considering Stone Bank Elementary, the school offers a small-school environment with strong academic results across most subjects and grades, in a community that is growing but still retains a rural character. The student population is not diverse, and the school’s middle grades show some dip in math and science performance that may be worth exploring. There are no high school grades here, so students would move to a different district or school for grades nine through twelve, and the data did not say where they typically go. The housing market in the area carries a price premium, reflecting the desirability of the Lake Country region of Waukesha County, which may be a factor in a family’s decision.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
