For Knewton to post grades to the LMS gradebook, students must launch an assignment, test, or quiz from the LMS. If a student does not launch an assignment via the LMS, a dash or a hyphen will show in the LMS gradebook as no connection has been made between it and Alta.
If scores are not being reported to the LMS gradebook, please verify that you or your students are always launching Knewton from the LMS course rather than going to knewton.com. Please note partial credit scores will not appear in the gradebook until the due date stipulated in Alta. See when scores are passed to the LMS gradebook in this support article.
If you use Blackboard, also keep in mind you do need to enable evaluation per assignment. Check out this support article on how to enable evaluation.
