St George's School in Marton has postponed its festive trip to France following last Friday's terrorist attacks in Paris.
Students were set to cross the English Channel on Wednesday, December 9.
The school, opposite Asda in Cherry Tree Road, made its decision at a meeting on Thursday and said in a statement: "Sadly, following the events in France of recent days together with the ongoing uncertain situation, we have made the decision to postpone this planned trip.
"We have taken advice from our government and the French government. This, together with the concerns of teachers, parents and children has contributed to this measured response and decision.
"Our thoughts and prayers are with those affected by this terrible situation."
On its website, the school said it runs a yearly trip to the Lille Christmas markets, and war museums in Northern France, for its Year Eight pupils.
Lille is around 140 miles by road from Paris, where Islamic State - or Daesh - terrorists killed 129 people and injured hundreds of others in coordinated bomb and gun attacks.
