Due Date vs. Lock Date

Due Date vs. Lock Date

Due dates signify when quizzes and assignments are due; however, they do not necessarily prevent student access after the due date has been passed. The due date places the deadline on the Calendar, To-do list, Syllabus Tool, and Modules page. Since due dates do not lock assessments, students are able to submit quizzes and assignments past the indicated deadline. Late submissions are identified with a red ‘late’ notice in the SpeedGrader as well as a red color indicator in the grade book.

The lock date is used to prevent late student submissions. Students in the course will only be able to access the quiz or assignment before the lock date is reached. Once the deadline has passed, only teachers and TAs will be able to view the assessment. Users who want to prohibit students from submitting late work often choose to match the due date to the lock date.

The following scenarios may be helpful in determining quiz settings:

  • Scenario #1: Student starts quiz before the due date. Due date is reached but the student still has time left according to the duration of the quiz.
    • The student will not have the full duration to take the quiz. Their quiz will be automatically submitted after a warning is displayed once the due date is reached.
  • Scenario #2: Lock date is reached but the student still has time left according to the duration of the quiz.
    • The student will not have the full duration to take the quiz. Their quiz will be automatically submitted, after a warning is displayed, once the locked after date is reached.
  • Scenario #3: Student starts quiz after the due date but before the lock date.
    • The student will have the full duration to take the quiz. It will be marked as Late.
