Turnitin in Cirrus

Turnitin has an integration with Cirrus so you can use it as an add-on in your Cirrus platform.

First need to have a licence with Turnitin for their Originality product, in order to use the integration.

Do you (already) have a Turnitin licence? Please contact Cirrus Sales Support via our Customer Portal or email to sales@cirrusassessment.com for more info on how to enable this add-on.

Once enabled in Cirrus your administrator can setup the integration in the admin panel. See this article on our developer page.

How does the Turnitin integration work

The steps below will guide you through the whole Turnitin integration from an author and candidate perspective.

Step 1: Setting up assessment with Plagiarism control

After activated the integration, a new checkbox will appear on the Step 2: Assessment options tab.

This means you are now able to turn on plagiarism detection on an assessment level.


Step 2: Marking

Plagiarism control will be shown directly on the submissions screens above the answer of the candidate.

When assessing the questions from tests with the plagiarism option on, a percentage appears indicating the likelihood that plagiarism has occurred.

Next to the percentage, click 'View report' for a Turnitin report with more details.

Plagiarism threshold

Essay submissions with less then 20 words will not generate a plagiarism report. So the integration will pick up on answers that contain at least 20 words.

Plagiarism limit

Turnitin will confert the text to UTF-8 first. When the conferted text is over 2MB of text, a plagiarism report will not be generated.

Also, a submission cannot contain more then 800 pages of text.

EULA for users

In order to process submissions trough Turnitin and to view the associated Plagiarism reports (i.e. Similarity Reports) users must agree to an End-User License Agreement (EULA).

The EULA will be shown once to each user after the first time they click on 'View report' when marking an Essay question. Or again, when the agreement is updated by Turnitin.

EULA for candidates

In order to process submissions trough Turnitin and to view the associated Plagiarism reports (i.e. Similarity Reports) candidates must agree to an End-User License Agreement (EULA) too.

The EULA will be shown once to each candidate after opening an exam. Or again, when the agreement is updated by Turnitin.

The order of appearance:

  1. Cirrus NDA page (optionally)
  2. EULA
  3. Cirrus Welcome page

If a candidate declines, the system will show a warning. The candidate cannot continue and will be logged out.

Candidates can only start the exam after agreeing to the EULA.

Welcome page
The welcome page also contains a notification about plagiarisme control. This note will only be visible when plagiarism control is turned on for this assessment.

I cannot see the Turnitin Similarity report
It might be the answer is to short for the tool to work. The candidate asnwer should have at least 20 words.

The similarity report is empty/gray
If this happens, please try to open the report again.

** When opening the similarity report I receive an error authentication error as below
Please refresh the Cirrus page and try again. It might be your session is expired with turnitin.
