Summary:
Hartland, Wisconsin is home to nine schools serving about 5,179 students — six elementary, two middle, and one high school — spread across six districts that all carry Hartland addresses: Arrowhead Union High School School District, Merton Community School District, Lake Country School District, Swallow School District, Hartland-Lakeside J3 School District, and North Lake School District. Grade spans vary widely — some buildings serve PK–2 or 3–5, while others are PK–8. All six districts earned five stars, and five rank among the top 10 of 432 districts statewide.
Swallow Elementary is the clear standout: the #1 district and #5 elementary school in Wisconsin, with roughly 89.4% average proficiency versus about 55.1% statewide, the lowest chronic absenteeism at 2.5%, and the highest per-student spending at $14,669. Lake Country School posts elite academics (about 87.7% proficiency, with 100% of 3rd graders proficient in math) but has the area's highest absenteeism at 11.5%. Merton Intermediate and Merton Primary rank 6th and 14th statewide respectively, with low absenteeism and poverty; Merton Primary spends the least ($12,082) yet still delivers top-tier results.
Arrowhead High anchors the area with 1,950 students, a 98.1% graduation rate, 0.0% dropout, and a 99th percentile rank. North Shore Middle shows high achievement despite the area's highest free/reduced-price lunch rate (15.82%). North Lake Elementary has the strongest English/language arts results and the lowest poverty (1.10%). South Elementary is the only 4-star school and has slipped in rank over three years, though every reported test score still beats the state. North Elementary serves PK–2, so it has no current state test data. Notably, every reported 2025–26 test score across these schools is above the state average, and average absenteeism is about 5.7% versus 17.3% statewide.
