Similarity report options

In the Assignment Inbox each student’s submission has a percentage score (with colour indicator) under the Similarity column. This represents the proportion of the total text in the assignment which matches other sources. This overall percentage score is known as the Similarity Index.

This ‘at a glance’ guide should not be used as a measure of plagiarism. Even a 1% score could potentially be plagiarised content.

Always check the Similarity Report for each paper in order to make a judgement about plagiarism.

What happens when student submits a paper to more than one assignment in the module

The submission will not match because of default self match exclusion. The self-match can be re-added to the report from the excluded sources section. More information on self-matching is available from Turnitin's helpsite.
