You can create a group assignment by using the Group Assignment checkbox. Canvas uses group sets to assign group assignments, and each group within the group set that is assigned to the assignment is required to complete the assignment. When creating or editing a group assignment, you can assign an assignment to specific groups. You can also set different due dates and availability dates for a group within an assignment that is assigned to the rest of the class.
You will need to assign a group set as part of the assignment. You can add an existing group set, or you can create a new group set as part of the assignment and add students to groups later. However, if you create a group set with self sign-up or manual group assignments, you will not be able to use the group set until users have been added to the subgroups.
When differentiating groups in assignments, students can only view the assignment if they are a member of an assigned group. Otherwise the assignment does not appear in the student's assignments page. Grades cannot be assigned for students who have not been included in the assignment, and assignments that are not assigned to a student are not factored into overall grades.
When Multiple Grading Periods are enabled in a course, assignments are also respected against closed grading periods.
- In group assignments, one submission will count for the entire group. Learn more about evaluating group work.
- Group assignments cannot be used with External Tool assignments.
- In group assignments, all students should be assigned to groups before the assignment is published. Grades and submissions may be affected for students who were not in a group at the time of assignment submission but who were later added to a group.

You can include more than one group in the Assign to field as long as the groups are to be assigned the same due and availability dates.
Edit Due and Availability Dates
In the date fields, add your preferred date(s) with the following options:
- Due : Set the date and time that the assignment is due. The due date will already be populated for you if you created an assignment shell, but you can change it if necessary.
- Available From : Set the date and time when the assignment will become available.
- Until : Set the date and time when the assignment will no longer be available.
Note: Beneath the Due Date and Availability date fields, Canvas will display the time zone date and time according to context. If you manage courses in a time zone other than your local time zone and create or edit a due date for an assignment, the course and local times are displayed for reference.

Note: This warning message will not appear if everyone in the course or all course sections are assigned.
View Date Error
If you submit an invalid string of due dates and try to save the assignment, Canvas generates an error notification. Such invalid entries include not unlocking the assignment before it is due, not placing the due date inside the range of availability dates, or assigning a date that is outside the course or term dates.
Correct the date and then update the assignment again.
- If the course does not include specified course start and end dates, Canvas validates the assignment against the term date set for the course.
- If your course is using Multiple Grading Periods, the Assign field validates the due date against the closed grading period and requires the assignment date to be past the date of the closed grading period.
