The school prom was originally set for downtown Chicago May 19, the same week as the NATO summit. School officials moved up the date because of possible violence during protests.
"We didn't know we were going until about a few weeks before prom, so it's fine by us," said prom-goer Margaret Stadtwald.
Principal Nathan Rouse notified parents by letters of his concerns.
"As a school, we want to be proactive and keep our kids safe at all times," Rouse said.
Students had mixed reactions to the change.
The earlier date meant less time to find a date and prepare for the big night.
And while the evening may have been impacted, some seniors here say it only makes a special night even more memorable.
"Being in dresses, you already get a lot of stares just when you're walking here," said Maureen Puccetti. "So if we were in the middle of a protest dressed like this, it would be a little different."
