Important to remember!

REMEMBER! Having similarities in your work DOES NOT necessarily mean you have committed plagiarism!  Your instructor will review the similarities and determine their nature. 

Turnitin DOES NOT determine whether you have quoted or cited correctly.  It only points out similarities of any kind.

If you are concerned about your Similarity Index, or your Similarity Report, schedule a meeting with your instructor.

Similarity Report Colour Indicators

The colour of the report icon indicates the similarity score 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 ranges 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
