Assignment Essentials

Turnitin is a plagiarism detection software used by the National College of Ireland.

As an NCI student, you will be asked by your instructors to submit assignments through Turnitin (via Moodle) so that they can, in a routine manner, check for originality issues with your papers.

Check out the following video from Turnitin to find out more, particularly about Originality Check.

One key misunderstanding occurs when students view their similarity score which gives a percentage in terms of how much of their paper is similar to other sources.

This is not a 'plagiarism percentage' and there is no acceptable percentage of plagiarism: the only acceptable amount of plagiarism in a piece of academic writing is zero!

There are legitimate reasons why a piece of writing would have similarities to other texts, including, most obviously, where a passage has been directly quoted (but done so legitimately, i.e. using quotation marks and appropriate in-text citation). See our Referencing and Avoiding Plagiarism guide for help with this!

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
