If a student is a full-time UNC System student, there is no additional charge for courses that they register for through the Language Exchange (it is covered by the student's tuition just as if they were taking it at their home institution, and there is no ‘billing’ for it from the host institution).
If a student is a part-time UNC System student, they will pay the home institution hourly rate for the course, and it will be billed to their home institution. If there is a specific class that a student is interested in, they must check with their home institution registrar to confirm the course rate.
The student’s home institution keeps the tuition portion of the funding, and the host institution receives the appropriation part.
