Yeah I mentioned it extremely briefly in my essays and have it on my resume, but it could easily be looked over. I have passed all 3 levels, which basically means when my work experience catches up (and unless I become a farmer or go live in a cave somewhere, its going to happen) I will have my charter. You may want to downplay the "quantyness" of it, but I came from a pretty non-target school, so I think this, along with my GMAT and good GPA, helps to assuage any doubts an adcom may have over my ability to handle the coursework.
Also, Columbia has a long history with the CFA, so if anyone values it, its CBS. I just want to make sure I get credit if any credit is due.
