Assignment parts functionality has been
removed from Turnitin with effect from the
introduction of Turnitin Feedback Studio
(2025).
Where a requirement arises to provide multiple part assignments on a module, this may now be achieved by creating an individual assignment for each discrete assignment part. Such cases may arise where, for example, dissertations are required to be submitted as (a) dissertation body and (b) ancillary sections such as bibliographic references and appendices.
