I have only OJT for CMM programming (and everything else), no formal education/credentials. I plan on testing for a ASQ QA/QC Tech certificate in the fall/winter. Other than that, I have no idea what I can do to help myself get a "leg-up" in this field. I would like to advance in it, though, since I have found I enjoy it and I'm pretty decent at it so far. So, any career advice?
