Normally when Moodle sends a submission to Turnitin it can take several minutes to an hour for the report to appear depending on the amount of requests for similarity reports Turnitin is receiving. Typically, students should see a notification that their file submission is being queued with a Turnitin ID being assigned shortly afterwards. A similarity percentage score should soon appear in the assignment submission area and the Gradebook shortly afterwards through which the similarity report can be accessed.
While Turnitin similarity reports are typically generated as expected there are times when a report is not generated for a submission. There are several reasons why a similarity percentage score and report might fail to be generated resulting in .
1. Assignment Settings
Firstly, it is important to check the Moodle assignment settings to determine whether reports are set to generate on due date or on submission. This is managed by the setting called ‘Report Generation Speed’.
Generate reports immediately (students can resubmit until due date): Originality reports will be generated for every draft a student submits, overwriting each time. After the third submission there will be a delay of 24 hours between generation of reports.
Generate reports on due date (students can resubmit until due date): An originality report will only be generated for the final file a student submits for an assignment.
2. File Types
3. Accepting EULA
4. Turnitin Service Disruption
First you should check your assignment settings to see whether reports are set to generate on due date or on submission. (See: When will I/my students see their originality reports?) If only a limited number of students are having this problem, the issue may be that they have submitted the wrong file type. (See: What file formats does Turnitin accept?.) Finally, the problem may be due to a delay on Turnitin’s side. (See: What happens if Turnitin is down?) If the problem persists, please contact eden.digital@lse.ac.uk for support.
