Coordinators and Directors are university staff who are responsible for students enrolled in their Subject (i.e., class) or Course (i.e., program). These are "sub-roles" within the Supervisor module.
Coordinator = a Sonia Online role for a staff/faculty member who oversees a Subject/class. Students are added to this person based on a Subject they are enrolled in. This person can see their students' placements, checks, enrollment history, and forms (with the right permissions).
Director = very similar to the Coordinator; the only difference is that this person oversees a Course/program. For example, all undergraduate students or all Elementary Education students.
These two roles usually do not have access to the client because they don't actually place students; all they need is found in Sonia Online.
The video below shows how to add students to these roles.
