Hi, Roz,
The threshold will vary – it very much depends on whether the piece is being used formatively or summatively, and the subject matter in question.
For example, if you have someone who is undertaking work where there are very few resources, then you would expect there to be a higher number of matches. Similarly, if you have an 1st year undergraduate group all writing about Freud’s theory of personality, say, then the matches would also be high.
Our advice is to check everything that comes back ‘red’ (75% +) and ‘blue’ (0%) (this usually indicates there are no citations/references in the piece). We also advise that all work is checked if a class consists of less than, say, 70 students, and that a sample of all work is checked if the students numbers are over 70.
Kind regards,
Anne

Subject: Use of turnitin advice
Hello
A quick straw poll, do any of your institutions use Turnitin?
and if you do, do you have a threshold percentage set for the originality report which triggers a plagiarism investigation?
I would be grateful of any feedback and process you put in place to support the threshold?
Thank you for your timeRegards
Roz”
