Note: You are currently viewing documentation for Moodle 2.0. Up-to-date documentation for the latest stable version is available here: Plagiarism Prevention Turnitin.

Template:Moodle 2.0

Turnitin administration

Location: Administration > Plugins > Plagiarism Prevention > Turnitin

Activation of your Turnitin Account

  1. obtain a Turnitin Subscription from
  2. Email your Turnitin Account rep or the Turnitin helpdesk and paste this text into the e-mail:
 Please manually enable my Turnitin account to use SRC=14 to allow the use of the Turnitin Plagiarism plugin for 2.0 written by Dan Marsden from Catalyst IT.

If you have seen previous Turnitin integrations/plugins you will know that there is an interface that allows you to enable the Open API, Basic, Direct API plugins for Moodle in your Turnitin Administration screen - unfortunately none of these options work with the new Plagiarism plugin for Moodle 2.0

Installation of the plugin

Installation using Git

from the root of your install:

 git clone git:// plagiarism/turnitin

then add plagairism/turnitin to your .gitignore Visit the Admin > Notifications page in Moodle to trigger the upgrade scripts

Installation using a Zip file

Download the zip: or the tar.gz:

Then Extract these files into a new folder under /plagiarism/turnitin and visit the Admin > Notifications page in Moodle to trigger the upgrade scripts

Global Configuration of Turnitin

  1. Ensure Admin > Server > Environment indicates you have curl installed
  2. Go to Admin > Advanced Features find the setting “Enable plagiarism plugins” - make sure the box is ticked. Enableplagiarism.png
  3. in the page Admin > Modules > Activities > Turnitin set the following:
    1. Tick the box "Use Turnitin Submission"
    2. Enter your Turnitin Account ID
    3. Enter your Turnitin Secret Key as obtained from your Turnitin Account Rep
    4. Elect whether to send students an e-mail to allow them to login to the site to view their submissions (this isn't necessary, and will likely cause your students more confusion, as all the information available in the website is available from your moodle site.) - even if no e-mail is sent, students can visit and use the forgotten password functionality on the turnitin site to get their password sent via e-mail. Admins can disable this by adding a prefix to all email accounts created - see below for details.
    5. Set the Student Disclosure statement. - this is displayed to all students on the upload screen to notify them that the Turnitin system is in use.

Configuration of Turnitin inside Moodle Activity Modules

Assignment Module

(currently only available with the advanced file upload and single upload types)

  • Create a new Assignment within your course.
  • Enable Turnitin Submission

Advanced Configuration

The ability to enable/disable Turnitin within a Moodle module such as an assignment is managed using a capability that is by default given to all managers and editing teachers on the site. If you want to force all assignments on your site to use Turnitin and prevent your teachers from changing these settings you can set the defaults above and then remove the capability “moodle/plagiarism_turnitin:enable” from your teacher roles.

You can also use this capability to selectively allow certain teachers to use Turnitin by setting the default above “Enable Turnitin” to “No” - and giving the capabiltiy “moodle/plagiarism_urkund:enable” only to the teachers you want to be able to use Turnitin


  • when testing the turnitin integration you should make sure debugging is turned on, as it will provide information regarding the process.
  • error codes recieved from the turnitin API are also logged in the mdl_tii_files table, so you can view issues with a production system.
  • each file that is going to be submitted to turnitin is added to the table mdl_tii_files - the field tiicode gives the "status" of the file, - there are 3 "good" states for this field:
  1. "pending" - this is a new file that has been uploaded to an activity module, and needs to be submitted to Turnitin (will happen next time cron runs)
  2. "51" - this is the turnitin API code for Successful upload - this means the file has been uploaded to Turnitin and we are waiting on an originality score,
  3. "success" - this is a file that has been submitted, and a score has been provided for it.

Any other response code in this field indicates an error state, see the Turnitin errors page for a complete list of codes.
