The instructions on this page state, "Students can view this assessment form in the submission phase." However, I cannot get the assessment form to show up when switched to student role, or even when I log in as a specific student. I'm using Moodle 2.8.7. I must be missing something, but what?
It is a bug in the documentation. Workshop does not provide explicit preview of the assessment form to students - see MDL-27239. As mentioned there, a way to achieve that is to make use of Example submissions.
Thanks for pointing that tracker item out to me, David. I have now voted for it.
