Turnitin is a similarity detection service which assists educators in identifying similarities between submitted papers and existing sources or to help students learn how to avoid plagiarism and improve their written work.

1. Follow the Create an Assignment guide to set up the Assignment activity.
2. Scroll down to Turnitin plugin settings.
3. Change Enable Turnitin to Yes.
4. Set Display Similarity Reports to No to prevent students from viewing their similarity report.
   • For formative exercises, you may want students to be able to view their report. If so, change this setting to Yes.
5. Select When should the file be submitted to Turnitin -
   • Submit file when first uploaded - the paper will be submitted for originality check immediately. This is the default, and cannot be changed, if Require students click submit button, is set to No.
   • Submit file when student sends for marking - the paper will be submitted when the student clicks on the submit button if Require students click submit button, is set to Yes.
6. Set Allow submission of any file type to No.
   • This will prevent students from uploading files that cannot be checked for similarity. See Turnitin's guide to understand permitted file types and sizes.
7. Set Store Student Papers to Standard Repository.
   • For formative exercises or draft submissions, change this setting to No repository so that the paper is not added to the Turnitin database and checked for similarity in future, for example, when the student submits their final version of the paper.
8. Set Check against stored student papers to Yes.
9. Set Check against internet to Yes.
10. Set Check against journals, periodicals and publications to Yes.
11. Set Report Generation Speed to the appropriate setting -
    
    • Generate reports immediately (Resubmissions are not allowed) – Originality Reports will be generated immediately, but only once the student clicks ‘Submit assignment’. Students cannot resubmit papers.
    • Generate reports immediately (Resubmissions are allowed until cut-off date) - Originality Reports will be generated immediately on upload. Students may resubmit as often as they wish by clicking ‘Edit submission’. Only the latest submission and originality report is available to the instructor or student. This option is typically used when students are self-reviewing and revising their submissions and able to view the Originality Report. PLEASE NOTE: Students may still re-submit work AFTER due date, unless you set a cut-off date the same as due date, which is advised and if you want to allow late submissions, simply set up a second assignment submission with appropriate settings.
    • Generate reports on the due date (Resubmissions are allowed until cut-off date) - Originality Reports will not be generated for any submission until the due date. Students may resubmit by clicking ‘Edit submission’ as many times as they wish, until the due date without receiving reports. PLEASE NOTE: Students may still re-submit work AFTER due date (a second Originality Report will not be created though). It is advised that you set a cut-off date, the same as the due date and if you want to allow late submissions, simply set up a second assignment submission with appropriate settings.
