Is there a stigma of assigning the title TA to an undergraduate? I am entering my senior year of undergraduate study in Computer Science at a small, primarily undergraduate institution. I plan to attend graduate school and pursue a PhD in Computer Science and Mathematics, my main goal to teach. The school I attend is quite small, and is all but unknown outside our geographic region. As such, I've attempted to add as many positive bullets to my CV as possible, mainly because I feel I will have to fight harder than my colleagues at larger universities to get into a great program.

One of the things I have attempted to add to my vita is teaching experience. I have had the opportunity to tutor in our Mathematics Tutoring Center for a couple years now, and have fallen in love. I have also had the pleasure of assisting a professor in her Freshmen CS labs. Last fall I spoke with her about increasing my duties to more than just fielding questions as the students type their programs. I wanted to start grading lab submissions, and perhaps even hold office hours. She was delighted that I wanted the increased responsibility, but sharply objected to calling it a "TA" position.

A teaching assistantship (TA) is a formal job category at most universities, which implies that you are being paid a specific wage for teaching duties while a graduate student. Consequently, you would be misrepresenting your work on the CV if you called yourself a teaching assistant, because you are not formally a graduate student.

At the university level, another issue may be that while many undergraduates do participate in teaching responsibilities at many schools, this is often in the form of tutoring programs and informal arrangements. Part of the reason for this is that many universities want to be able to claim a higher percentage of teaching duties are done by faculty than is really the case. Calling undergraduates graders and tutors helps to shift off the balance, since they are not officially "teaching staff," and therefore wouldn't be included in such time accounting.
