More than 600 students will receive diplomas from Worthington's two high schools Sunday, May 25.
The Worthington Kilbourne High School commencement is scheduled for noon at the Battelle Grand in the Greater Columbus Convention Center, 400 N. High St.
The Thomas Worthington ceremony will follow at 4 p.m. in the same location.
From Kilbourne, 297 are expected to graduate, with more than 100 to receive honors diplomas.
From Thomas, 372 will be eligible to graduate, but 346 plan to participate in commencement exercises. Seventy-two will receive honors diplomas.
At both ceremonies, Superintendent Thomas Tucker will speak, and school board president Julie Keegan will accept the classes from Kilbourne principal Angie Adrean and Thomas principal James Gaskill.
The schools' bands and choirs will perform.
At Kilbourne, speakers will be 2014 class president Dillon Castelli and student-body president Lauren Hedges.
At Thomas, speakers will be class president Chloe Beck and student-body president Jasmin Singh.
Students have been preparing for this day for their whole lives, said Ken Nally, Kilbourne assistant principal.
"We are so proud of them," he said.
Gaskill said the Thomas class is a special group of students and he will be sad to see them leave the school.
They are the "GussStrong" class that has rallied behind popular teacher and coach Stephen Gussler during his fight against stage-4 colon cancer.
"It's an exciting time but also a time of reflection, a time to think about people whose lives have made such a difference," Gaskill said.
