Summary

Clarendon Avenue Elementary is a PK–6 school serving 511 students in Mukwonago, WI, a Waukesha County community in southeastern Wisconsin, and it is the largest elementary in the Mukwonago School District.

Statewide, Clarendon ranks 104th of 1,039 Wisconsin elementary schools (90th percentile, 5 stars) in 2025–2026 — a top-decile school, and a rebound from 156th (85th percentile, 4 stars) the year before, its best standing since 2021–2022. It beats state averages in every subject and grade, by roughly +15 to +27 points. Math improved most: the four-grade average rose from 72.0% to 77.0% year over year, and the gap over the state widened to about +24 points. The school's most distinctive strength is attendance — just 1.0% chronic absenteeism, against 3.8% for the district and 17.3% statewide. That is exceptional for any school, and especially notable because Clarendon serves the district's highest-poverty elementary population, with about one in five students qualifying for free or reduced-price lunch, a share that has been rising.

Two things are worth knowing. First, inside Mukwonago, Clarendon looks more average than it does statewide: it trails the district average in every subject and grade and sits behind Section Elementary, Big Bend Elementary, Rolling Hills Elementary and Prairie View Elementary on test scores — but the district itself is a state standout, so middle-of-this-pack is still top 10% statewide. Clarendon also clearly outperforms Eagleville Charter School, despite that school's lower poverty rate and higher per-pupil spending. Second, two areas are worth watching. Special education performance has slipped from the 92nd to the 75th percentile over two years, and low-income student performance from the 91st to the 84th, while 6th-grade reading is now the school's lowest reading grade. Both remain solid — just no longer trending up.
