Moodle - Submission Statement
In Moodle, there is an option to make students check a box to ensure the work they are submitting is their own work.
This article is about the submission statement option in Assignment settings.
When enabled, students will see this message that they will have to check to submit their work:
They will not be allowed to submit their work until they have checked that statement.
To enable submission statements, an instructor must go to the assignment they would like to edit and click on Edit Settings in the "Administration" block.
Then, select Yes from the "Require that students accept the submission statement" drop down in the "Submission settings" section.
Select Save and return to course or Save and display at the bottom of the screen to save the changes.
