Extensions & Re-dos
Give students extra time beyond the due date or allow them to completely retake a completed viva.
Overview
Extensions and re-dos are time-based accommodations that help students who need flexibility with deadlines. Unlike permanent accommodations (which follow a student across all assignments), these are granted per-student, per-assignment.
Extensions
Extra time beyond the due date. The student keeps all progress and can continue where they left off.
Re-dos
A fresh start. All previous responses are deleted and the student begins the viva again from scratch.
Extensions
Extensions give students additional time beyond the assignment due date. This is useful for students who need extra time due to illness, personal circumstances, or documented accommodations.
Available Extension Options
| Option | Hours Added | Use Case |
|---|---|---|
| No extra time | 0 | Default (remove an extension) |
| +1 day | 24 | Minor delay or technical issue |
| +3 days | 72 | Short-term illness or conflict |
| +7 days | 168 | Extended circumstances |
| +14 days | 336 | Maximum extension |
Reviving overdue assignments: Extensions can be granted even after the due date has passed. This allows you to "revive" access for a student whose assignment shows as overdue.
Extension vs Extended Time
Do not confuse extensions with extended time accommodations:
Extension (this page)
Extra days past the due date to access and complete the viva.
Extended Time (accommodation)
Increased prep and recording durations (25%, 50%, 100%) during the viva itself.
Where to Grant Extensions
Extensions appear in the "Actions" column for students who have not yet submitted their viva. Click the Extension button to reveal the dropdown menu.
Extension dropdown from the Batch Review table:
Example row showing an overdue student with extension control:
| Student | Assignment | Completed | Status | Actions |
|---|---|---|---|---|
Emma Wilson emma.wilson@university.edu | — | — | overdue |
After granting a 3-day extension, the button shows the current extension:
Re-dos
A re-do allows a student to completely restart a viva they have already submitted. This is a more significant action than an extension because it wipes all previous work.
Destructive Action
Granting a re-do permanently deletes all of the student's audio/video responses and any grading or feedback. This action cannot be undone.
What Happens When You Grant a Re-do
- All responses are deleted (audio and video files are removed from storage)
- Session status resets to PENDING (as if the student never started)
- Student automatically receives a 7-day extension from the current date
- Student can start fresh with all questions available again
- Action is logged in the audit trail for compliance
Restrictions
7-day window: Re-dos can only be granted within 7 days of the original due date. After this window closes, the button becomes disabled.
TAs cannot grant re-dos: Only the course instructor can allow a student to redo a viva. Teaching assistants will see the button disabled with a tooltip directing them to contact the instructor.
Only for completed sessions: Re-dos are only available for vivas that have been submitted (COMPLETED or REVIEWED status). You cannot redo a viva that is still in progress.
Where to Grant Re-dos
The "Allow a Redo" button appears in the Actions column for completed or reviewed vivas. It appears next to the Review/Open button.
Redo button in the Batch Review table:
| Student | Assignment | Completed | Status | Actions |
|---|---|---|---|---|
James Chen james.chen@university.edu | Module 3 Oral Assessment | Jan 28, 2026 | pending review | |

The redo button may be disabled in certain situations. Hover over the button to see the reason.

Confirmation Dialog
When you click "Allow a Redo", a confirmation dialog appears to prevent accidental data loss.
The confirmation modal:
Redo this viva?
This will remove all responses and any grading for this viva and give the student 7 days from now to resubmit.
