Lannon Elementary, Lannon WI - Test Scores & Data

Original Research by School Decision on Lannon Elementary

Lannon Elementary serves kindergarten through fourth grade as a regular public school within the Hamilton School District in Waukesha County. It is a single-school building in a small village, and its grade span is short: students will leave after fourth grade and move to a larger elementary or intermediate school in the same district. For families considering this school, the academic picture is the clearest signal, and it is a strong one.

On state assessments, Lannon Elementary’s students perform above the midpoint relative to other schools in Waukesha County. Proficiency rates across math, English language arts, science, and social studies are consistently solid, with the highest rates in math at grade four and social studies. The school’s overall proficiency index places it comfortably above the county median, a cohort of two dozen districts. This is a school where, on the whole, students are meeting or exceeding academic benchmarks at a rate that many nearby schools would envy. Because the school ends at grade four, there is no graduation rate to report, and no chronic absenteeism data was available.

The student body is predominantly white, with a visible Asian population making up a meaningful share and small percentages of Black, Hispanic, and multiracial students. Economic disadvantage is low: the share of students qualifying for free or reduced-price lunch is modest, well below state averages. Data on students with disabilities and English learners were missing from the available records; a parent may want to follow up with the school directly about those supports.

Lannon itself is a village with a working quarry heritage, dotted with active stone operations that have been in the same families for generations. It is not a place with a walkable downtown or a dense commercial core. Parks, trails, and baseball fields anchor community life. The Bugline recreational trail runs through town, and Menomonee Park offers a quarry lake and miles of walking paths. Housing values in the area are above the national and state median, consistent with the broader Milwaukee metro’s more affluent suburban fringe. The county’s housing market has been active, with moderate price appreciation and a modest increase in days on market, but it remains a relatively competitive market for buyers.

The Hamilton School District, which oversees Lannon Elementary, recently secured a voter-approved referendum to exceed its state revenue limit for non-recurring operational expenses over a three-year period. That decision directly funded programs and operations during a time of constrained state funding, and it suggests a community willing to invest locally in its schools. What larger curriculum changes, facilities plans, or longer-term financial pressures the district faces were not detailed in the available records.

For a family considering Lannon Elementary, the appeal is straightforward: a very strong academic start, a low-poverty student population, and a small-scale village setting that feels removed from the busier corridors while still being part of a respected suburban district. The main limitation is the grade span—the transition after fourth grade may matter to some families and is worth understanding in terms of where their child would land next. If a parent values academic rigor, a tight-knit school community, and a community with a distinct industrial heritage rather than a typical bedroom suburb, Lannon Elementary fits that profile well.

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.
