Interpreting Turnitin reports
January 9, 2017
The percentage indicates the amount of text in your essay that directly matches text in the Turnitin database. Thus, a long reference list, a lot of quotes, and the repetition of common phrases can result in a high percentage of matches. If the matches are taken from an outside source and have not been referenced then this could indicate a problem. To avoid this, make sure you include in-text citations (or footnotes) for direct quotes and paraphrased information and include a full reference list for all sources cited in the assignment.
