I have found a way to see the student assessments of faculty-posted example posters. Reports, Log, use the drop down slots, including Workshop for activity. The log has a link when add assessment of example (don't remember the exact wording), and clicking on that link leads to the student's assessment for that example. This is useful for identifying students who are following, or not following, instructions for the assessment. Unfortunately, I don't think this is exportable.
Wow! That's really hacky I was not aware of this path, to be honest. Thanks for sharing this tip Annette!
