Turnitin External Tool

This tool is only available in Canvas Assignments, and when the submission type is set to “External Tool”. It will generate Turnitin Similarity Reports, spelling/grammar suggestions (if ETS e-rater is enabled), and allow instructors to use additional Turnitin tools for leaving feedback and grading; such as Turnitin QuickMarks and Rubrics, and Turnitin PeerMark.

The Turnitin Feedback Studio or Canvas SpeedGrader can be used to enter grades and provide inline comments, however the Turnitin Feedback Studio is used to access reports, and the additional Turnitin tools.

If instructors do not intended to use Turnitin’s suite of Feedback Tools and just want to obtain the Similarity Report, then we recommend using Turnitin’s Plagiarism Review tool instead of their External Tool.

Note: The Turnitin External tool option does not not support group assignment submissions in Canvas.
