This is an assignment where students upload a Word document. How do I set the assignment so after the assignment has been graded the student isn't allowed to submit another document in that same assignment?
The only way to prevent students from uploading another document is to set an Until date on the assignment. If you just have a due date, Canvas will let them submit the assignment after that date, but will mark that submission as late.
To clarify, there is no way to stop students from submitting again once they have submitted an assignment as long as the until date hasn't passed. So yes, they can't post again after the until date, but yes, they can post as many times as they want leading up to the Until date.
