Summary:
Families in the Grafton area have one public middle-school option: John Long Middle, located at 700 Hickory St in Grafton, WI. It serves grades 5–8 with an enrollment of 452 students and is the only middle school in the Grafton School District. Because it is the district's sole middle school, every district-level test score and attendance figure is identical to the school's, so no within-district comparisons are possible.
John Long Middle is a high-performing, 5-star school. It ranked 44th of 643 Wisconsin middle schools in 2025–2026 (93rd percentile, 5 stars), 43rd of 628 in 2024–2025 (93rd percentile, 5 stars), and 70th of 641 in 2023–2024 (89th percentile, 4 stars) — an improvement from 4 to 5 stars. The district ranks 18th of 432 districts statewide (96th percentile, 5 stars). Proficiency is above the listed state average in every reported subject and grade. In 2025–2026, math averaged 76.41% versus a 53.69% state average (+22.72 points), ELA averaged 71.90% versus 54.57% (+17.33), grade-8 science was 74.68% versus 51.86%, and grade-8 social studies was 79.74% versus 64.63%. Math was especially strong in 2024–2025, when grade-7 math reached 85.62% (+30.09 over state) and grade-8 math reached 82.47% (+29.41). Science also improved year over year, from 67.53% to 74.68%.
Attendance is a major strength: chronic absenteeism was 3.1%, well below the district's 4.7% and the state's 17.3%, and the reported dropout rate was 0.0% against a 1.1% state rate. Resources include $13,578 in spending per student, a 15.1 student–teacher ratio, and a 14.38% free/reduced lunch rate. Note that year-over-year test-score changes compare different grade-level cohorts, not the same students, so dips in grade-7 and grade-8 ELA should be read with that in mind. No test scores in this data set were suppressed, and all listed scores are exact percentages.
