The most common problems

ProblemWhat to check
I cannot find the Turnitin assignmentCheck the correct online classroom, the section and the opening date – see Where to find the assignment. If the activity is not there, contact the instructor.
The file will not uploadCheck the file format, the size, password protection and the internet connection. For a PDF, check that it contains real text and not just scanned images.
The wrong file was submittedIf resubmission is enabled, submit the corrected file. If the option is not available, notify the instructor immediately.
The similarity score is not shownThe report may still be generating, the instructor may have hidden it, or it may be set to be generated only at the due date.
The report will not openCheck pop-up blocking in your browser, refresh the page, or try another supported browser.
I do not know whether the submission went throughCheck the status, the date and time of the submission and the Digital Receipt – see Checking your submission.
The due date has already passedIf late submission is not enabled, contact the instructor. The instructor sets the rules; Turnitin cannot change them.

Recommendations for a safe submission

  • Do not submit the assignment right before the due date.
  • Before uploading, check the file name and the content of the document.
  • After submitting, save the Digital Receipt and the Submission ID.
  • If the Similarity Report is available, review the sources and the matches, not just the percentage.
  • Before resubmitting, save a copy of the previous version on your computer.
  • If the system is not working, document the problem with a screenshot as soon as possible and notify the instructor or support.
