About St. Charles Community Unit School District 303

Students are off September 3, 2027, for an institute day and September 6 for Labor Day. October 7–8 are conference and high school in-service days without students, followed by the October 11 holiday. Including the weekend, students have five consecutive days without classes. November 1 is another no-school day for school improvement.

Students have no classes November 22–26, although the calendar labels November 25–26 as Thanksgiving Break. District offices remain open November 22–24. Winter break runs December 20–31, followed by a staff day on January 3; classes resume January 4, 2028. Spring break is March 27–31, with students returning April 3.

The February 24 conference day affects grades differently. Pre-K has no classes, while K–5 students attend in the morning only because of afternoon parent-teacher conferences. The calendar does not list a conference-related closure for middle or high school students that day. All students are off February 25 for institute and work-day activities.
