Due date extensions can be set in your Knewton alta account. Alta will send back grades to your Learning Management System for quizzes, assignments, and tests at the extension due date. Due dates will not be automatically updated on your LMS, and so individuals with extensions will not see the extension date on their LMS. They can only see the extension within the Knewton alta iFrame.
Because of this, we do not recommend setting due date gating on the LMS side and, instead, using Knewton’s Late Completion and Extensions to perform gating. This ensures that students have access to their learning history as well as extra practice after the due date.
Grades will be updated in the LMS after an extension date passes, providing a student's grade changed.
