Clarendon Avenue Elementary, Mukwonago WI

Original Research by School Decision on Clarendon Avenue Elementary

Clarendon Avenue Elementary serves students from pre-kindergarten through grade six in Mukwonago, a village in Waukesha County that functions largely as a commuter community for Milwaukee while holding onto a small-town feel shaped by the Phantom Lakes and the Mukwonago River. The school is one of several elementary buildings in the Mukwonago School District, and its location on Clarendon Avenue places it within the village's residential fabric, not far from the historic downtown core.

The school reports strong participation on state assessments, with all tested students taking part. In math, proficiency rates across grades three through six run at a level that is a clear strength for the school. English language arts proficiency is more variable, with some grade levels performing well and others showing a softer spot that a parent may want to look into further with the school. Science and social studies results are reported for fourth grade only, with social studies showing particularly solid performance. When placed against other districts in Waukesha County, the school's overall proficiency index sits below the midpoint of that group. That comparison is useful context: the county includes many districts with high performance, so a below-midpoint position does not indicate a struggling school, but it does mean that families comparing schools across district lines will find several with higher aggregate scores.

The student body is predominantly white, with a smaller share of students who are Hispanic, and very small numbers of Black, Asian, and multiracial students. Roughly one in five students qualifies for free or reduced-price meals, a share that is moderate and well below the state average for elementary schools. Data on special education and English learner enrollment were not available; a parent may want to ask the school directly about support services for those populations.

Mukwonago's housing market is expensive relative to national benchmarks. The village has seen steady residential growth over recent decades, particularly after the completion of the interstate that made commuting to Milwaukee more practical. Housing stock leans toward single-family homes built since the 1970s, and the village has continued to annex land from surrounding towns, suggesting ongoing development pressure. For families moving into the area, housing costs are a significant factor.

The district itself has no major recent changes that would affect a family's decision, based on publicly available information. There were no recent referendums, curriculum overhauls, or facility updates that cleared a lasting-impact threshold. The school appears to operate as a stable neighborhood elementary with a regular academic program; no data on specialized programs, magnet or charter status, or course access beyond the standard curriculum was provided, so a family looking for specific enrichment or gifted offerings would need to check directly.

Clarendon Avenue Elementary offers a typical public elementary experience in a suburban village with above-average housing costs and a strong testing culture in certain subjects. The overall proficiency picture is solid but sits behind many other districts in the county, which may matter to families weighing options across district boundaries. The school's moderate level of economic diversity and its consistent participation in state testing suggest a stable, mainstream environment for children through sixth grade.

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.
