Conferences can be a great way of promoting your career on many levels. For freshly minted grad students, applying as an image maker at a conference is a great way to show potential employers or new employers that you are serious about blending your academic activity with your artistic activity. If you are interviewing at the College Art Association, being able to invite prospective employers to your presentation will look great. For those already in a job, image maker presentations are wonderful, but mix it up a little and apply for or create panels in areas related to teaching as well as your artwork.
Administration likes to see that you actually participate in conferences, not just attend them. This could be in the form of panels, presentations, portfolio reviewer, committee involvement, mock interviewer. Get in the habit of writing a narrative about your conference activities to get a sense of your general involvement and how that could improve.
If you are just getting started and still looking for a job, take advantage of any mentorship program, mock interviewing, portfolio reviewing that your professional association or conference might offer. Regularly apply for image maker or conference sponsored exhibitions as a way of getting your work seen by your peers.
