Is anyone here familiar with how exactly a tuition "supplement" differs from a tuition waiver? While I understand a graduate program's guarantee of a tuition waiver to mean that the student does not pay the university's tuition, I'm not sure if a "supplement" equates to this or not. The program (University of SC - Columbia) does note that they offer stipends, which suggests that tuition would be covered*, but they also say students receive in-state tuition status, which doesn't seem relevant unless that cost actually needs to be paid out of pocket. Does anyone have experience with this? I know that funding packages offered by public schools, especially those with lower rankings, can be lackluster compared to those of shiny, upper-tier private schools, but the lack of even a tuition waiver seems a bit much. I would also think they wouldn't advertise the want of such basic funding on the program's FAQ. But, then again, their mention of in-state tuition status suggests tuition might be at least partially covered by the student. Should I contact the department about this or should I not concern myself too much about it until I actually have an acceptance (with, presumably, a more explicit funding package) in hand?
Thanks in advance.
*If the department offers money to the grad student in the form of a stipend, I would assume that the tuition payment is covered. If a student gets a stipend but not a tuition waiver, their stipend money would just go toward paying tuition, anyway, so why would the university give them money that will just be returned in the form of tuition?
