If you have elected to award credit for partial completion but not allow late completion, then the percentage of mastery on an assignment at the due date will be sent to the LMS gradebook.
If you have elected to award credit for partial completion and allow late completion, the percentage of mastery will be sent to the gradebook only at the alta due date, but students can continue working on assignments and achieve 100% mastery for a modified grade in alta and the LMS gradebook.
If you change your grading policies after student grades have already been recorded (after the beginning of the course), any grade changes will be applied retroactively. For example, if you decide to enable late completion when it was previously disabled, grades will be updated for any students who worked after the due date and had grades that were previously not calculated.
