Check the internship course listing for your major in your academic catalog to determine the number of credits assigned to the course. Sometimes, there is a range of eligible credit. In those cases, you will need to work with your instructor in The Global Education Office to determine the number of credits that may be appropriate for you given the length of the semester. You may benefit from having a curriculum review done by the Undergraduate Advising Center.
In addition to the number of credits, the course description will also state whether the course is letter- graded or evaluated on a Pass/No Pass basis.
The tuition for the internship course is the same per credit cost as any course.
