The cancellations are in the wake of a fire in Preble High School's gym, early Friday morning.
Many of the items that were scheduled to be handed out to students, such as textbooks and packets were damaged by the smoke.
School officials say the smoke damage to Preble High School was extensive. Those items need to be cleaned before they can be handed out to students.
Students were initially scheduled to register on August 13th and 14th, with a makeup date on August 19th. School officials say they're working to keep parents up to date on any more changes in the wake of last week's fire.
