Chicago Public Schools officials said its students in France have been accounted for.
Students from Lincoln Elementary and Chicago Agricultural High School are currently in Paris on trips.
A series of attacks across Paris on Friday thrust the city into chaos, leaving at least 129 people dead, including a 23-year-old American woman, in the deadliest violence to strike France since World War II.
Eight attackers targeted at least six locations in the French capital, authorities said. Police said they killed one of the terrorists and the others blew themselves up.
Americans were among the 352 wounded, the State Department said. French President Francois Hollande vowed a "merciless" response against the perpetrators, as ISIS claimed responsibility.
"CPS students on school trips to Paris are accounted for and safe," said CPS spokeswoman Emily Bittner in an email.
Chicago Mayor Rahm Emanuel called the attacks "despicable" and "horrifying."
