By now, CFA candidates know whether or not they have passed or failed. If you didn't pass this time, don't take it too badly. If you retake, use the hundreds of pre-preparation hours as an advantage.
Of course, after results day, there's a shift in terms of candidacy statuses. For those of you who either passed or are retaking level I this December, you may be thinking about how you can best leverage your CFA status to spruce up your CV. However, one very important factor to bear in mind are the ethics and professional standards set up by CFA Institute on stating such things on your CV. Without knowing it, many candidates are in violation of these bylaws and could be sanctioned by CFA Institute.
