When a faculty member needs to grade a student who failed to launch a Portfolium Assignment, the student does not get added to the Portfolium course roster. A one click roster sync and/or continuous sync from Canvas LMS to the Outcomes Assessment Platform should happen now that Portfolium is part of the Instructure family.
Why is this important? The Canvas Outcome Assessment platform has rubric and outcome data. This data will be skewed if a faculty member cannot assign a grade of zero for a student who fails to submit.
