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 campus, and there is no ‘billing’ for it from the host campus).
If a student is a part-time UNC System student, they will pay the home campus hourly rate for the course, and it will be billed to their home campus. If there is a specific class that a student is interested in, they must check with their home campus 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.
