A typical submission made to an assignment on Turnitin generates an Originality Report. The Originality Report is the result of comparison between the text of the submission against the search targets selected for the assignment which may include billions of pages of active and archived internet information, a repository of works previously submitted to Turnitin, and a repository of tens of thousands of periodicals, journals, & publications. Any matching or highly similar text discovered is detailed in the Originality Report that is available in the assignment inbox.
Originality Reports provide a summary of matching or highly similar text found in a submitted paper. When an Originality Report is available for viewing, an icon will appear in the report column of the assignment inbox. Originality Reports that have not yet finished generating are represented by a grayed out icon in the reports column. Reports that are not available may not have generated yet, or assignment settings may be delaying the generation of the report.
Note: Overwritten or resubmitted papers may not generate a new Originality Report for a full twenty four hours. This delay is automatic and allows resubmissions to correctly generate without matching to the previous draft.
The color of the report icon indicates the Similarity Index of the paper, based on the amount of matching or similar text that was uncovered. The percentage range is 0% to 100% The possible similarity indices are:
- blue - no matching text
- green - one word to 24% matching text
- yellow - 25-49% matching text
- orange - 50-74% matching text
- red -75-100% matching text
Warning: These indices do not reflect Turnitin’s assessment of whether a paper has or has not been plagiarized. Originality Reports are simply a tool to help an instructor find sources that contain text similar to submitted papers. The decision to deem any work plagiarized must be made carefully, and only after in depth examination of both the submitted paper and suspect sources in accordance with the standards of the class and institution where the paper was submitted.
