School calendar and holidays in Wisconsin

The 2026–2027 year in Wisconsin

Milwaukee is the district we track in Wisconsin — largest district in wisconsin. On its official calendar, classes start on September 1, 2026, winter break runs December 21 – 31, 2026, spring break runs Mar 26, 2027 – Apr 2, 2027, the last day is June 15, 2027.

The district summarises the year as follows: “School starts September 1, 2026; Thanksgiving runs November 25–27; winter break runs December 21–31; spring break runs March 26 to April 2, 2027; the last day is June 15, 2027.” Every one of those dates is copied from the district page, which is linked in the table below with the date it was checked.

Other districts in the state set their own dates, so treat this as one verified example rather than a statewide rule. Confirm with your own district before booking travel.

Where Wisconsin sits among the states we cover

Across the 23 districts we track nationwide, the first day ranges from August 3, 2026 at DeKalb County to September 10, 2026 at New York City. The last day ranges from May 21, 2027 at Fort Worth ISD to June 28, 2027 at New York City.

In Wisconsin, the earliest first day among the districts we track is September 1, 2026 at Milwaukee, and the latest last day is June 15, 2027 at Milwaukee. A date that is early in one state can be late in another, which is why a national “back to school” date does not exist.

How schools are organised in Wisconsin

Wisconsin has no statewide school calendar: each district sets its own, subject to state instructional-hour rules. Milwaukee Public Schools, the largest, opens later than most of the country — the Tuesday after Labor Day — and closes in mid-June.

Exams

The SAT and ACT run on national dates, not state ones. See the full SAT and ACT 2026–2027 calendar for every session, registration deadline and score release.
