Departments can nominate two (or more) support staff, who can act as Canvas representatives for your school/department. These representatives are given a sub-account admin status and will have access to all courses created in Canvas that belong to your department/faculty/school. Do seek your leadership approval, when you submit this list. To nominate, please submit your list here.
Alternatively, administrative support staff who assist in managing course sites can also request the faculty member to provide you with access to their courses.
