Good question. In consideration of FERPA, the librarian role specifically doesn’t have access to student grades or to student submissions for assignments or quizzes. The role only has access for the purpose of providing assistance to students, so the librarian can see course content and assignment instructions (so as to know what is expected of the students) and discussions and the classlist so that they can post to the discussion topics and email the students. The role is an attempt to emulate the experience of a librarian coming to a classroom to help students, likely on specific projects, such as a research paper.
