Seamless Integration: The Instructor’s Guide to Turnitin LTI 1.3

Turnproai Contributor • July 24, 2026

For years, instructors faced a frustrating dual-platform dilemma: grading a paper in Turnitin.com, then manually transferring that grade over to their Canvas, Blackboard, or Moodle gradebook. The introduction of LTI 1.3 (Learning Tools Interoperability) has completely transformed this workflow, embedding Turnitin's powerful tools directly into your existing LMS ecosystem.

The LTI 1.3 Advantage

If your institution has upgraded to the Turnitin LTI 1.3 integration, you no longer need to navigate to an external website. The connection handles the heavy lifting of roster management and data synchronization behind the scenes.

  • Automatic Roster Sync: Gone are the days of sending students enrollment keys and class IDs. As soon as a student is enrolled in your Canvas/Blackboard course, they are automatically recognized by Turnitin.
  • Seamless Grade Pass-back: When you enter a score using Turnitin Feedback Studio, that grade instantly pushes to your LMS gradebook. No more manual data entry errors.

The "Where Do I Grade?" Dilemma

The biggest point of confusion for instructors when using an LMS integration is deciding where to actually leave feedback. If you use Canvas, for example, you have a choice: do you grade in Canvas SpeedGrader, or do you grade in Turnitin Feedback Studio?

Best Practice: Choose One and Commit

If you want to use Turnitin's QuickMarks, audio feedback, and Similarity checking simultaneously: You must grade inside the Turnitin Feedback Studio window. Set up the assignment as an "External Tool," click into the Turnitin dashboard, and do your grading there. The grade will pass back to the LMS.

Important Warning: If you leave comments using Turnitin Feedback Studio, but then type a grade into Canvas SpeedGrader, you risk overwriting the Turnitin grade pass-back connection. Always grade in the same environment where you leave the comments!

Avoiding the Due Date Desync

Another common LTI pitfall is due date synchronization. Because you are linking two separate systems, you often have to set the Due Date in your LMS (so it appears on the student calendar) AND set the Due Date inside the Turnitin LTI assignment settings (so Turnitin knows when to stop accepting papers).

Always double-check that your Canvas/Blackboard due date perfectly matches your Turnitin inbox due date. If they conflict, the Turnitin settings will usually override, potentially locking students out early!

Conclusion

Setting up Turnitin LTI 1.3 within your Learning Management System might take an extra two minutes during assignment creation, but it saves hours of administrative headache at the end of the semester. By understanding how the data flows between the two platforms, instructors can create a frictionless submission and grading experience.
