You can change sharing permissions for your assignments to control whether or not other instructors can schedule your assignments to their classes, or to collaborate with specific instructors when creating assignments.
Important Changes to assignments can affect scoring for both current and past scheduled
assignments. To avoid creating a situation in which assignments might have to be rescored,
do not allow
other instructors to schedule your assignments until after you are done making changes.
