As long as the student remains enrolled at their home institution for the summer term, they can use the Language Exchange to register for summer courses without additional cost or paperwork.
Note: For Distance Education courses, Summer is funded identically to Spring and Fall, so if your students/courses are reported as DE, they will receive the state appropriation that is allocated to your institution. Some of the confusion on this issue has come from the fact that once the appropriation is distributed, each institution can (and does) treat it differently, so internal allocation may vary in the summer sessions.
