The schedule covers everything from a senior reflection program and a prom night at one of Chicago's most iconic venues to a scholarship ceremony and an outdoor commencement on Bennett Field. Here is what every LTHS family needs to know.

Prom is open to LTHS students with senior class status and their guests. Non-LT guests must be at least high school age and no older than 20 years old. All LT students must have a parent or guardian sign a Prom Permission Slip. Non-LT guests must complete a separate Non-LT Guest Request form. Families with questions about guest policies should visit lths.net/activities/events/prom or contact Student Activities Director Kris Costopoulos at kcostopoulos@lths.net.
Post-Prom Cruise
Saturday night into Sunday morning, May 16–17, 2026 | Departing Navy Pier | 11:45 p.m. – 2:30 a.m.
After Prom ends, students who purchase Post-Prom tickets will board the Oddyssey and the Spirit of Chicago for a Lake Michigan cruise departing from Navy Pier. The cruise runs from 12:30 a.m. to 2:30 a.m. and features an open buffet, DJ entertainment on multiple levels, and an open-air observation deck with views of the Chicago skyline. Buses return to South Campus at approximately 3:00 a.m.

Last Day of Classes for Seniors
Friday, May 22, 2026
Friday, May 22 is the final day of classes for Class of 2026 students. The school has noted that all summative assessments for seniors should be completed before this date so that students have the opportunity to retake any assessments before their last day.
Graduation Rehearsal — MANDATORY

All students who plan to participate in the Commencement ceremony must attend the mandatory Graduation Rehearsal on Tuesday, May 26, at South Campus. The exact start time has not yet been announced.
LT Class of 2026 Commencement
Wednesday, May 27, 2026 | Bennett Field, South Campus | 7:00 p.m. 4900 S. Willow Springs Road, Western Springs, IL 60558
The Class of 2026 will walk at Commencement on Wednesday, May 27, at 7:00 p.m. on Bennett Field at South Campus. LTHS is continuing its tradition of hosting Commencement outdoors on Bennett Field.
Rain contingency: If inclement weather forces a postponement on May 27, the ceremony will move to Thursday, May 28, also on Bennett Field. If weather prevents an outdoor ceremony on both May 27 and May 28, Commencement will be held on Friday, May 29 on Bennett Field. In the event that weather prevents an outdoor graduation throughout the entire week, LTHS may move Commencement indoors to the North Campus Fieldhouse (100 S. Brainard Avenue, La Grange).
