 Purpose
Exclude Quotes/Exclude Bibliography
You may wish to exclude quotes, bibliographies, and items of a similar nature from influencing your students' similarity scores.
Exclude small sources (measured by word number or percentage)
 You can exclude sources in the source list that are below the threshold set by you. For example, if the threshold is set at 3%, any 1% or 2% match would be removed from the current report mode's source list.
Generate a new Similarity Report
If you believe an item may have been added to the Turnitin database since a Similarity Report was last generated (this could be a website, journal article, or even another student’s paper), you can generate a new report to receive an up-to-date similarity score. This can be done by Rerunning the Reports from the main submissions screen, within the Turnitin Assignment.
To Re-run reports after you have clicked Apply Filters, navigate back to the Student Submissions screen and along side the submission list click the button to Re-run Reports:
