Note: Linked on the district calendar page as the 2027-28 district calendar (grid dated June 22, 2026). The version posted for the spring 2026 calendar survey was marked DRAFT; this one is not, but neither the document nor the page states an approval. Break names come from the listed 'District Calendar 2027-28' on the same page, which agrees with this grid. Oct. 18 and March 6 are staff development days with no school for students. Grades 9-12 also have no school on Friday, Jan. 14, 2028 (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 20 for high school and 19 for PK-8, January 19 for high school and 20 for PK-8). Lincoln's Day is observed on Nov. 24, inside Thanksgiving week. Juneteenth (June 19) falls after the last day of school.

Note: Calendar for IUSD's year-round schools (PK-8 instructional days only). Linked on the district calendar page as the 2027-28 year-round calendar (grid dated June 22, 2026); the survey version from spring 2026 was marked DRAFT, this one is not, but no approval is stated. Year-round students start Tuesday, July 20, 2027. The Year Round Fall Break runs Sept. 20 - Oct. 8 and Spring Recess March 27 - April 7 for year-round schools. Aug. 13, Oct. 18 and March 6 are staff development days with no school for students. PK-8 schools have one floating teacher work day in October whose date is not on the district calendar (check with your school), so the computed count is one day above the stated 180.
