Canvas allows you to set a different due and/or availability date for one or more students. You can do this for assignments, discussions, and quizzes. Here's what you need to do:
1. Go to Canvas and edit the item.
2. Scroll to the bottom of the page, to the "Assign" section, and click the "+ Add" button.
3. Click in the "Assign to" box and start typing the student's name (1).
4. Click on the name to select it (2).
5. Set the "Due" and "Available from" dates for this student.
6. You'll now see two sets of due dates, one for that student, and one for "Everyone Else."
7. Click the "Save" button at the bottom of the page.
