Wisconsin School Calendar 2026-2027

Wisconsin's public school system is overseen by the Wisconsin Department of Public Instruction (DPI) and serves students across approximately 420 school districts, ranging from large urban systems like Milwaukee Public Schools to small rural districts in the Northwoods. The state requires 180 instructional days per academic year, with most districts beginning in early September after Labor Day and concluding in mid-June. Wisconsin has a strong tradition of local governance in education, and individual school boards retain significant authority over calendar decisions, curriculum, and staffing. The state is home to one of the nation's oldest and largest school choice programs: the Milwaukee Parental Choice Program, established in 1990, which provides vouchers for low-income students to attend private schools. Wisconsin administers the Forward Exam in spring for grades 3 through 8, measuring proficiency in English language arts, mathematics, and science, as well as the ACT Aspire for high school students. The state's northern districts, particularly those in areas with significant tourism and outdoor recreation industries, may adjust their calendars to accommodate local community needs. Wisconsin also observes a number of state-specific holidays and professional development days that can vary by district. Families should verify specific calendar dates with their local school district, as break schedules and start dates can differ across Wisconsin's diverse regions.
