We fetch this document again every day and compare it with the version we verified; if the district changes it, the dates here are read again.

Note: IUSD's March 16, 2026 article on the 2027-28 calendar survey refers to the approved 2026-27 traditional and year-round calendars; the file is named 'Final'. Break names come from the district's listed 'District Calendar 2026-27' on the same page, which agrees with this grid. Oct. 12 and Feb. 12 are staff development days with no school for students. Grades 9-12 also have no school on Friday, Jan. 15 (Teacher Work Day/Student Holiday, traditional schools only); PK-8 students attend that day. PK-8 schools instead have one floating teacher work day in October whose date is not on the district calendar (check with your school). Both groups have 180 instructional days (the grid's monthly counts: October 21 for high school and 20 for PK-8, January 18 for high school and 19 for PK-8). Lincoln's Day is observed on Nov. 25, inside Thanksgiving week. Juneteenth (June 18) falls after the last day of school.
