Set up plagiarism settings

9.     Save or Save Publish your assignment. As Canvas may not immediately notify Copyleaks that an assignment has been created, we suggest waiting up to 90 seconds between creating the assignment and making the first submission. This will allow Canvas to notify us that the assignment has been created.

Setting Similarity Report availability

Set Similarity Report availability

When creating the Assignment, you can choose if and when the Similarity Report will be shown to students.

  • Immediately: The Similarity Report will be available for students to view as soon as their submission has been given a plagiarism score (Finished processing on Copyleaks)
  • After the assignment is graded: The Similarity Report will be able for student viewing once the assignment has been graded in Canvas.
  • After the due date: The Similarity Report will be available to students when the assignment due date has passed.
  • Never: The Similarity Report will never be shown to students but will be available for instructors to view when submission has received a plagiarism score from Copyleaks.

Accessing Similarity Reports

The Similarity Report can be accessed from within SpeedGrader.

  1. Select SpeedGrader from the right-hand side of the assignment.

2.    To view your Similarity Report, click on the percentage that is shown on the right side of the SpeedGrader. For this example, the percentage is 100%.

View Similarity Report

3.    The similarity report will open in a new tab. Learn more about interpreting the similarity report and results here. Below are two examples of reports:

  • Breakdown of 3 types of similarity levels
  • A report that contains a Suspected AI Text alert

4.    If a student's similarity report is still generating, you will notice a 'pending clock' alongside that student's submission as well as within SpeedGrader. This clock will disappear once the similarity report has fully generated. If a student's similarity report generating process failed, you will notice an 'exclamation mark' alongside that student's submission as well as within SpeedGrader. Click on it to show the error.


Important Information

  1. As Canvas may not immediately notify Copyleaks that the student submission has been created, we suggest waiting up to 90 seconds before clicking on the resubmit button. This will allow Canvas to notify us that the assignment has been created.
  2. If a student uploads multiple versions of a document to the same assignment, we will NOT compare to their previous submissions. For example, if a student uploads Version 1, Version 2, and Version 3 of a document, we will NOT scan Version 3 against Version 1 and Version 2. However, if the student has uploaded this document to a different assignment, it will be compared. For example, if the assignment is uploaded to English 101 and History 101, we will compare the two against one another.
  3. When Duplicating / Importing / Copying an assignment, the assignment Copyleaks configuration settings will NOT be copied into the new assignment.
  4. If your admin has enabled the Show student information in results setting, instructors and admins will be able to see:
    1. The date  time of submission for the detected result.
    2. The user (via their email or username) who submitted the detected result.

See the screenshot below for an example of what this will look like on a similarity report.
