Make sure you are serious about the opportunity.
Administrators at Gallery Diet in Miami say a common misconception of art gallery internships is that, "they're just a fun, easy going way to get college credit. " They explained via email, "We work hard to ensure that our internships provide an experience that can be carried into the work place. We structure reading programs, access to artists and clients, and insist that in return the intern be serious, dedicated and committed to their work." So be sure you are in it for the right reasons.
