Summary
Grafton High is a public 9–12 high school in Grafton, Wisconsin, a suburban community north of Milwaukee, serving 727 students as part of the Grafton School District, which ranks 18th of 432 districts statewide. The school itself ranked 42nd of 533 Wisconsin high schools in 2025–2026 (92nd percentile, 5 stars), and it has stayed in roughly the top 5–10% of the state for most of the past decade, peaking at 14th of 431 in 2024–2025. Among nearby schools, Cedarburg High and Homestead High are the closest benchmarks that consistently rank higher, with Port Washington High essentially tied with Grafton.
Academics are a clear strength. In 2025–2026, Grafton 10th graders beat the state in every subject: math 66.29% proficient versus 42.93% statewide, science 68.54% versus 43.2%, social studies 63.37% versus 48.25%, and English language arts 61.8% versus 48.47%. Math and science are the standout areas, outperforming Nicolet High, Germantown High, Ozaukee High, and Brown Deer Middle/High. Only Cedarburg and Homestead did better in those subjects. ELA is the relative soft spot: still comfortably above state, but behind Cedarburg, Homestead, Port Washington, Germantown, and Nicolet.
School completion results are exceptional. Grafton posted a 99.4% graduation rate and a 0.0% dropout rate in 2024–2025 — the best completion figures in the nearby comparison group. Chronic absenteeism was 5.9%, far below the state's 17.3%, though Nicolet (2.8%) and Ozaukee (2.1%) were even lower. Grafton spends $14,486 per student, below most nearby suburban peers — Nicolet, for instance, spends over $22,000 — suggesting strong efficiency, with a student-teacher ratio of 15.6. Two things worth watching: proficiency dipped from 2024–2025 highs, especially social studies (77.27% to 63.37%), and relative effectiveness for low-income students fell from the 97th percentile two years ago to the 74th in 2025–2026, still above average but the most notable gap.
