You can set a grace period that extends homework due dates for your learners. The grace period applies to the whole course; you cannot set different grace periods for individual assignments.
The grace period setting does not apply to open response assessments. For details about setting the response date for an ORA assignment, see Specify Assignment Names and Dates.
On the Grading page, under Grading Rules & Policies, enter a value in the Grace Period on Deadline field. Enter the value in Hours:Minutes format.
