Summary:
Delafield, Wisconsin has exactly one public school: Cushing Elementary, serving grades PK–5 with about 281 students. That means families in the city have a single in-city option for elementary school — and no public middle or high school located in Delafield at all. Cushing belongs to the Kettle Moraine School District, which ranks 68th of 432 districts statewide (4 stars).
By performance, Cushing is a standout. It ranked in the 93rd percentile of Wisconsin elementary schools in both 2024-25 and 2025-26, earning a 5-star rating each year and finishing 73rd of 1,039 schools in the most recent year — a top-decile position that held steady rather than spiking and falling back. The school beat the state on all eight reported tests in both years, with margins ranging from +10.8 to +29.4 points. Averaged across those tests, Cushing's proficiency was 77.6% in 2025-26, versus 70.1% for its district and 54.7% statewide, and its advantage over the district widened from +3.4 to +7.5 points in a year when the district's average slipped. Third-grade math posted the biggest single gain (+10.4 points, to 82.22%). Chronic absenteeism was just 3.9%, compared with 8.5% district-wide and 17.3% statewide.
Two items to watch: fifth-grade ELA, the only test where Cushing trailed its own district (68.09% vs. 72.32%, a 9.9-point drop from the prior year), and fourth-grade math, which fell 6.8 points but still finished well above district and state averages. Resources are favorable — $17,141 per student, a 12.2:1 student–teacher ratio, and 9.96% free/reduced lunch. One coverage gap matters for planning: the data stops at grade 5, so student outcomes after elementary school are not visible here.
