An action of unknown
means that the admissions office has not heard from the department regarding their decision; please contact your department to see where they are on their decision making process.
If you have been accepted conditionally, it means that the admission office does not have your final transcript. Most likely you have not graduated or you have not provided a transcript with your final transcript or certificate of graduation. Conditional acceptance does not hinder you from registering or enrolling in classes. It is required for you to provide your official transcript or certificate to the Office of Enrolled Student Services during your first semester enrolled at Clemson University.
An action status of rejected means that the department to which you applied did not recommend acceptance. Please contact the program that you applied to for further details.
