Summary:
Elementary schools in the Germantown School District — County Line Elementary, MacArthur Elementary, Amy Belle Elementary, and Rockfield Elementary — serve PK–5 and together enroll 1,682 students, from 344 at Rockfield to 496 at County Line. The Germantown School District ranks 54th of 432 Wisconsin districts (88th percentile, 4 stars), but its four schools vary widely on their own statewide ranks, from 65th to 293rd.
County Line and Amy Belle are the standouts. County Line ranks 66th of 1,039 (94th percentile, 5 stars) with the highest 2025–26 derived average proficiency (79.6%), the lowest chronic absenteeism (2.3%), the lowest free/reduced lunch (5.85%), the lowest per-student spending ($11,833), and the highest student/teacher ratio (17.5). Amy Belle ranks 65th of 1,039 (94th percentile, 5 stars) and is the biggest improver, climbing from 250th to 65th in three years, with 78.7% average proficiency. MacArthur has improved each year (241st to 129th) and posts 72.6% average proficiency, though it has the highest free/reduced lunch (22.02%) and absenteeism (7.4%) in the group. Rockfield has slipped from 144th to 293rd, with the lowest average proficiency (67.2%), the lowest student/teacher ratio (13.9), and the second-highest spending ($12,907); its grade 4 ELA (53.45%) and science (51.72%) are its weakest results, while grade 5 ELA (83.64%) and math (78.18%) are strong.
All four schools exceed the state’s 54.7% average proficiency and sit far below the state’s 17.3% chronic absenteeism. Social Studies grade 4 is a district strength (79.31%–92.05%), while science is more uneven. Free/reduced lunch does not map neatly onto achievement here, so other factors appear to be at work.
