Turnitin Feedback Studio Viewer session extension

After listening to customer feedback, we’ve extended the session time for our viewer from one hour to three. This change means instructors will have longer to grade and leave feedback without worrying about being timed out.

2020 February 13th

Rubric manager issues have been resolved

Some users had experienced varying problems with our rubric manger such as not being able to select a rubric, create a new one, and formatting issues. The bug that caused this issue has been fixed and users should be able to use rubrics again as a part of their assignment.

2020 February 6th

We are now fully compliant for the release of Chrome 80

With the release of Chrome 80 fast approaching, we have ensured that users will be able to use our products in Chrome without further disruption. We have made the required changes to our cookies for all of our LMS integrations and Single Sign-On integration Shibboleth to ensure that users will no longer encounter warnings about 3rd party cookies if they are enabled.

2020 February 5th

This change does not require a plugin update.

Star rubrics and grading forms for easy access

Time for a little (early) Spring cleaning! This new feature allows you to star up to five rubrics and grading forms. Starring a rubric or grading form will move it to the top of the Rubric and Form manager for easy access. Starred rubrics and grading forms will stand out amongst all the others in this and future assignments.

2020 January 15th

This change does not require a plugin update.

A new sub-menu for rubrics and grading forms

By default, we provide many rubrics and grading forms to help you get started with your Turnitin account from the very first time you access it. However, as we have a global community of instructors and institutions, it is only natural that not every rubric is relevant to every instructor. To help with the organization of rubrics and grading forms, we’ve moved them to their own sub-menus within the Rubric and Grading Form Manager. This sub-menu is more visible on the screen, making it easier to scroll through and find the one you would like to attach to an assignment. The currently attached rubric or grading form is always visible from the top-level of the menu.

2019 October 23rd

Match overview percentage now appears for translated matches in English

A bug had prevented the overall percentage wouldn’t show after clicking the ‘View English Sources (beta)’ button. We're happy to report that this bug has been squished and the match overview percentage will now display as expected.

2019 September 18th

Anonymity is maintained when duplicating assignments

A bug had potentially caused anonymity to be lost when opening Turnitin Feedback Studio when an assignment was duplicated and a student submitted before an instructor had accessed the settings page. This has now been resolved and anonymity will be maintained at all times.

2019 September 13th

Continued accessibility improvements

Focus order for interactive elements is more logical

When a screen reader looks at a page, it goes through the elements on the page in a set order. We have changed the tab order within our text-only viewer to add a more logical progression through the page.

New ‘Skip to Content’ link as the first navigable element in the text-only viewer

When using the ‘Show highest matches together’ or ‘show matches one at a time’ modes of the text-only viewer, you’ll now find a ‘skip to content’ link as the first element that is reachable when using the tab key. Following this link will jump you to the first part of the similarity report.

2019 September 3rd

Fixed a bug causing Turnitin Feedback Studio Viewer to freeze

A pesky bug was found that would cause the Turnitin Feedback Studio Viewer to freeze when creating a comment. We squashed this bug as part of our ongoing commitment to improving the Turnitin Feedback Studio Viewer.

2019 August 21st

The undo prompt will now disappear as intended

When you delete a QuickMark, we show an undo prompt at the top of the screen to help you recover from any accidental misclicks. This undo prompt will vanish a couple of seconds after your next interaction with the viewer. A bug had made this prompt stay on the screen permanently. Now, deleting a QuickMark should only show the undo prompt for the intended amount of time.

2019 June 18th

Turnitin messages now appear within Speedgrader

If a student’s submission fails to generate a similarity report, a descriptive message will appear to instructors in Speedgrader explaining why. For example, if a submission does not meet the minimum word count required to generate a report, a message will appear explaining “Your submission must contain 20 words or more”.

2019 April 4th

Text-based submissions can now be greater than 10,000 characters in length

We’ve resolved a known issue with our text submission for Canvas Plagiarism Framework and LTI. When using our 'text' or, as you may also know it, 'copy and paste' upload, a limit on this field had restricted the number of characters you could send to Turnitin to 10,000 characters. This issue has been resolved.

2019 March 21st

You can now use resubmit to Turnitin when using SpeedGrader for group submissions

While it was possible to resubmit to Turnitin when using SpeedGrader for single submissions, it was not possible to use it for group submissions due to the underlying logic of how we process files for multiple students. However, we have reworked how group submissions are handled once they reach Turnitin and applied a change that now makes it possible to resubmit to a group submission!

2019 March 12th

Updated similarity scores will pass back to Canvas on the assignment due date

On the due date for an assignment, Turnitin automatically reruns the similarity score to help check for collusion or find any updated matches. A confluence of problems had prevented Turnitin from successfully sending this updated similarity score back to Canvas.

With this release, we have fixed these underlying issues and scores will now successfully update in Canvas on the due date.

2018 December 5th

Anonymous marking now supported!

Anonymous marking is now supported with both the Canvas Plagiarism Framework and Canvas LTI integrations!

This means that the feature only needs to be selected from within the Canvas assignment settings, which will then automatically apply to the Turnitin assignment settings.

Check out our guidance for help getting anonymous marking set up.

Anonymous marking differs in our Canvas integrations. Anonymous marking in Turnitin is a permanent setting. If you disable anonymous marking on an assignment following a student submission, you will be unable to reactivate it. This differs from the Canvas workflow. In the Canvas Plagiarism Framework and Canvas LTI integration you will be able to reactivate the anonymous feature even after a student has submitted. If you reactivate anonymous grading in Canvas after a submission has been made, the identify of the student will remain visible within the Turnitin viewer.

2018 November 21st

SpeedGrader resubmission bug

We’ve fixed a bug that was causing already graded submissions not to process when the “Resubmit to Turnitin” button was used. The “Resubmit to Turnitin” button now works in SpeedGrader after a submission has been graded.

User details from Canvas now stored in Turnitin

We are now retrieving basic user details which should help improve the quality and timeframe of support we can provide.

2018 October 17th

We’ve improved how we manage key dates when copying an assignment

When copying a Canvas Plagiarism Framework assignment, all settings are copied from the original assignment, including key assignment dates. However, when a copied course contained a start date more than a year in the past, this caused Turnitin assignment creation to fail. Not to worry… we’ve fixed this by automatically updating dates that are too far in the past to guarantee smooth assignment copying from here on out.

Students can successfully view their Similarity Reports

We found that students were unable to view their Similarity Report in some copied courses as a result of the “Allow students to see Similarity Reports” setting being set to “no” in or We’ve fixed this issue so that students always have the correct access to their Similarity Reports, regardless of any external settings.

2018 October 4th

We've fixed the duplicate student problem plaguing some users

We have fixed an intermittent issue where some students submitting to Turnitin via the Canvas Plagiarism Framework have had a duplicate user created in Turnitin. This resulted in students sometimes receiving 100% matches to their own paper, due to Turnitin considering a single student as multiple users with the same paper. Duplicate users should no longer be created, and if your institution has potentially experienced this with any assignment, please contact the Turnitin product support team and we will work to resolve this for your account.

2018 September 4th

A minimum of one repository must be selected to generate Similarity Reports

We realized that it should be possible to only deselect a maximum of two repository options in your assignment settings, whilst leaving one repository as a minimum requirement. With no repositories to search against, it was impossible to generate a report. Oops!

Available repository options include: Student, website, and periodicals, journals, and publications.

2018 August 30th

Administrators can now set up the Plagiarism Framework with Turnitin sub-accounts

Previously, only the Turnitin accounts that you administered could be linked to Canvas for use with the Plagiarism Framework. Now, you can link any of your main account's sub-accounts to Canvas, even if a sub-administrator is assigned to it.

2018 August 24th

We've made Turnitin assignment settings easier to follow

We received some feedback from users that the "Store submissions in" drop-down menu appeared broken and unusable. The reality was that their administrator had opted for all submitted papers to be stored in the standard repository. This automatically disabled the drop-down menu.

Now, when a Turnitin administrator chooses this option, we'll remove the "Store submissions in" drop-down menu completely:

Introducing ETS e-rater® to the Canvas Plagiarism Framework!

Pressed for time? We can help with that! Grab a snack, sit back, and relax as you watch Turnitin's grammar feedback technology automatically check your students' submissions for grammar, usage, mechanics, style, and spelling errors. ETS e-rater® provides rich, in-depth feedback with customizable on-paper marks to make the grading process even easier.

To start using ETS e-rater®, administrators must enable this on their account. Once enabled, instructors can configure e-rater® grammar check technology right from their Canvas Plagiarism Framework assignment settings!

2018 April 5th

No more duplicate papers after grading in Canvas SpeedGrader

We've been working with Canvas to resolve an issue with papers duplicating in and; this followed grading within Canvas SpeedGrader. The good news is that we've fixed it! There is no bad news!

Turnitin now rejects any unsupported file or submission types

We received reports that some papers submitted to the Canvas Plagiarism Framework were stuck in a pending state; we found that this was mostly down to unsupported file types being submitted. To prevent users from seeing this pending state in future, Turnitin will immediately reject any unsupported file or submission type.

Turnitin supports the following Canvas submission types:

  • Text entry
  • File upload (this includes cloud submission e.g. Google Drive). Accepted file types for generating a Similarity Report can be found here.
  • Turnitin does not support the following Canvas submission types:

  • Website URL

  • Media recordings

If a submitted paper fails to generate a Similarity Report and no pending message is displayed, students should review our file requirements and resubmit with an accepted file type.

Assignments are now created with start dates before due date

When using the course copy or import course content methods in Canvas, we’re often supplied with the due date for an assignment, but not a start date.

Due to Turnitin’s date logic/requirements, assignments failed to create when the due date was set to a past date and no start date was provided; this is because Turnitin sets the start date to today, and in Turnitin, the assignment can't be created unless the start date is before the due date.

To resolve this, we now always ensure that the assignment start date is set prior to the due date supplied to us. It's worth noting that Turnitin does not require a start and end date to produce a Similarity Report within the Canvas Plagiarism Framework. Start and end dates are controlled by Canvas.

Our guidance will soon cover the supported course copy/content import methods supported by Turnitin.

2018 March 20th

Set up group assignments using the Plagiarism Framework!

The start date of a Canvas Plagiarism Framework assignment failed to match the start date of the same assignment inside Turnitin, with the Turnitin start date appearing to be a full day earlier than the creation date in Canvas. We've pushed a fix to ensure that Turnitin accurately displays an assignment's start date and time.

An alert is displayed when using an unsupported environment for testing

The next time you attempt to register Turnitin in a test or beta Canvas environment, you'll be alerted that Instructure/Canvas does not support this. While we encourage testing in supported environments only, you can continue testing in the current environment at your own risk. If you have any questions about testing support, please contact your Canvas representative.

For reference, Canvas does not reliably support the Canvas Plagiarism Framework in the following environments:



For guaranteed quality assurance, all testing should be carried out in the production environment only:


A multi-file submission will now process successfully

If a student submitted multiple files for a single submission, we found that the first paper managed to process just fine, but the rest sat pending or in an error state. We made a few tweaks, and now, all acceptable files will indeed process, rather than just one. Phew!

2018 February 26th

We've introduced full support for copying a course

News just in! Any assignments created as part of the Canvas Import course content feature will automatically copy Plagiarism Framework settings from the original assignment. This makes for a snappy turnaround when creating new assignments! Not quite sure how to do this? Take a look at Canvas guidance for importing course content.

You can now exclude small sources from the Similarity Report

It's all happening in Canvas! We've just added a setting to the Plagiarism Framework to allow for the exclusion of small sources from the Similarity Report.

During assignment setup, you now have the option to set a small source exclusion value; this value can be a number of words or a percentage. To exclude small sources, Turnitin looks at the size of a matching source and makes any necessary exclusions based on the threshold specified.

Your storage repository options now populate correctly

We noticed an issue with the options available in the Store submissions in drop-down list within the Canvas Plagiarism Framework settings. After making some backend adjustments, the drop-down list now populates with the correct options, depending on the administrator's configuration (remember that the available repository options vary based on this configuration!).
