Topic Overview

How to interpret the colors and percentages on the Originality Report:

  • Blue - No matching
  • Green - One word to 24% matching text
  • Yellow - 25% - 49% matching text
  • Orange - 50% - 74% matching text
  • Red - 75% - 100% matching text

The originality report is NOT a plagiarism report. 

The matching text found is not an assessment of whether work has or has not been plagiarized. Originality reports can help locate potential sources of plagiarism. The decision to deem any work plagiarized should be made only after careful examination of both the submitted paper and the suspect sources

As a guide, a returned percentage of below 15% would probably indicate that plagiarism has not occurred.  However, if the matching text is one continuous block this could still be considered plagiarism.  A high percentage would probably be anything over 25% (Yellow, orange, or red). This will depend on the student's work and the requirements of the report or essay
