These directions will allow you to comply with the additional time requirements that students may need as part of their academic accommodations, determined by the Office of Accessibility Services.
Availability Window Requirements
NOTE: The availability window contained in your Quiz's "available from/to" fields needs to be long enough to accommodate your OAS students' additional time needs, or else the additional time will not be added to their quiz successfully.
For this reason, we recommend that you use one of these options to ensure that your OAS students successfully receive the additional time mandated by their academic accommodations:
- Expand the Canvas Quiz's availability window for the entire class.
- Create a separate availability window for just your students with OAS accommodations so they have a different (larger) availability window than the rest of the class. Our differentiated due dates article contains step-by-step directions for assigning individual students different availability and due dates.
Steps to Add Additional Quiz Time
- Click into your Canvas course site.
- Select Quizzes from your course navigation menu on the left side of the screen.
- On the Quizzes page, locate the published quiz whose time you want to adjust for a student. Click on the quiz's title.
- Select the Moderate This Quiz option that displays in the upper right corner. This set assumes you have already set a Time Limit on the quiz.
- On the Moderate Quiz page, locate the student(s) for whom you want to adjust the quiz time. Check the gray box to the left of each student whom you wish to give extra time. Then, scroll down to the bottom of the page and select Change Extensions for x Selected Students.
- On the Student Extensions pop-up window, enter the extra time in minutes that you want your student(s) to have for each attempt.
Example: If the quiz has a 30-minute time limit but you want to give 50% extra time, type 15 minutes.
- Click the Save button.
