Mequon-Thiensville School Calendar: Dates for 2026–2027
Whether you’re arranging child care, planning family travel or simply trying to keep track of late starts and early releases, the Mequon-Thiensville School District calendar requires a little extra attention.
MTSD publishes separate calendars for four groups: 4K, grades K–5, grades 6–8 and grades 9–12. Many holidays and breaks apply district-wide, but conference days, late starts and early dismissals can vary by grade level.
We reviewed all four official calendars to create this family-friendly guide. Families should still check the official MTSD calendar page before making final travel or child-care plans because dates remain subject to change.

MTSD builds two emergency or inclement-weather days into the school calendar. May 28 is scheduled as a regular instructional day unless the district uses only one emergency day. If only one emergency day is needed, May 28 becomes a day off for students.
Families should avoid making firm plans for May 28 until the district confirms its status later in the school year.
Last Day of School
The final day depends on grade level:
Wednesday, June 9 — Last day for 4K students
Thursday, June 10 — Last day for students in grades K–12, with early dismissal
