Thanks, tyr. I was basing my understanding of UNC's use of graduate student TAs on a number of reports. My H is a UNC graduate and has said that many of his classes in the first two years (in the French, English, political science and psychology departments) were taught by TAs. Yes, I know that was a loooooong time ago, and it sounds like UNC must have made an effort to reduce those numbers since then. Still, UNC does have graduate students, so I'm assuming they must teach some classes.
When my D and I attended scholarship day two years ago, some of the students on the panel were up front about having had classes and/or recitations taught by TAs but noted that if you were in the honors program it was less likely to occur. One of the student panelists even said he thought sometimes it was better to have a TA than a professor.
And then I have seen some threads here on CC, such as this one (specifically posts ##14 and 23):
UNC is NOT for everyone Everyone jumped on this person who reported his experience, but I have no reason reason to doubt what he reported. Different kids, different experiences.
