About Naperville Community Unit School District 203

Naperville 203 students have a three-day Thanksgiving holiday, November 25-27, rather than the full week. Classes are scheduled for November 23 and 24. Earlier in the fall, students have no classes October 8 for an institute day or October 9 for parent-teacher conferences. Together, these dates give students five consecutive days without classes, from October 8 through October 12.

Winter vacation runs December 21 through January 1. Students also have January 4 off for an institute day, so they return Tuesday, January 5. Spring vacation is scheduled for March 29-April 6. Because March 26 is a separate school holiday, students have no classes from March 26 through April 6, including the intervening weekends. Classes resume April 7.

Friday, May 7, is a half-day for K-12 students, while Early Childhood has no classes. The district calendar does not list dismissal times, so check with your school before arranging pickup or afternoon care.
