The Late Submission policy allows you to automatically deduct points on all late submissions. A submission is labeled late when it has been submitted past the due date. Only assignments with a status of Late will be affected by the Late Submission policy. The late policy will be applied to a submission when it is graded.

Late Submission policies only apply to the course in which they are configured. Late Submission policies will affect previously graded assignments, but do not affect assignments in closed grading periods or submissions for students with concluded enrollments. Disabling a Late Submission policy will not remove late penalties from previously graded assignments.

The Late Submission policy allows you to define a percentage of the total points possible on an assignment that will be deducted for late submissions. Points can be deducted per day or hour the submission is late. For example, if the Deduct field is set to 10%, the interval is selected for Day, and the assignment is worth 10 points, 1 point will be deducted per day. If a submission is 2 days late, and the student is awarded full points, their final grade on the assignment would be 8 points (2 days late x 1 point deduction per day = 2 point Late Penalty).

To calculate a late penalty, Canvas rounds up the day or hour to the next whole number. For example, you may set a 10% per day late submission policy. If a student submits a 10-point assignment 1.3 days late, the late penalty will round 1.3 days up to 2 days. The student's score will reflect a 20% (2 point) late submission deduction.

Additionally, you can define the lowest possible grade threshold for a late policy. The lowest possible grade percentage is the lowest score a student can receive when late policy deductions are applied to grades entered above that percentage. Any grade awarded equal to or below that percentage will not receive late policy deductions.

For example, if the Late Submission policy is set to deduct 10% per day for late submissions, and a student submits 8 days late to an assignment worth 10 points, the student's grade would be 2 points if they were awarded full credit on the assignment (8 days late x 1 point deducted per day = 8 point Late Penalty). However, if the Lowest grade possible is set to 60%, the student's grade will be adjusted to 6 points. Any grades awarded that are less than or equal to 6 will not have late policies applied.

Notes:

• Setting a Late Submission policy affects all assignments in a course, including assignments with due dates in the past. To exclude a specific assignment, mark the submission as something other than Late in the Grade Detail Tray.
• For the calculation of the Late Penalty, days late will be rounded up to the next whole number. For example, if a student submits 1.3 days late, the Late Penalty will treat the student as 2 days late. This behavior also applies for hour durations.
• Applying a deduction to late submissions will automatically affect any previously graded submissions. Therefore, the Late Submission policy should be set up when a course is created prior to creating assignments.
• The Late Submission policy will not affect submissions in closed grading periods or submissions for concluded enrollments.
• The Late Submission policy will not be automatically applied to No Submission or On Paper assignments. However, you can change the status of a submission in the Gradebook and add a Late label to the submission in the Grade Detail tray.
• The Late Submission policy will not affect submissions for Complete/Incomplete assignments.
• The Late Submission policy may not work correctly when applied to a quiz created using the Classic Quizzes tool and when also using a Missing Submission policy. To ensure the late deduction is properly calculated for these quizzes, you must set an Until date and time that occurs after the Due date. If you do not set an Until date for the quiz, you can set the quiz fudge points to 0 in SpeedGrader when grading the quiz.
• When taking a multiple-attempt quiz, a student who makes a new attempt after the due date has passed will receive deductions on all attempts, including attempts made before the due date.
• The Late Submission Policy is not supported when using multiple attempts in New Quizzes.
