Sorry if this has been dealt with already, I searched the forums and only found 1 thread talking abt the relative importance of admission criteria and where teaching experience fits in. (And didn't find much information other than Cornell does ask abt undergrad TA-ship experience)
Would you guys say that teaching assistant-ship falls under the category of "good to have but not super-crucial" or "useful occasionally but otherwise unimportant"?. It also seems to depend on whether the schools you apply to need teaching assistants desperately or not.
I'm asking because I'm tentatively considering TA-ing for a professor in an applied regression (Stata/Intro to Applied Metrics) course next semester, but am wondering if the time is better spent on making sure I do well in Econometrics and Probability Theory, and writing up my thesis. If people think it falls under the latter category mentioned above, then I'll probably withdraw from the TA-ship.
Thoughts? I'm hoping this thread could be useful for others as well.
