Viola,
you bring up a great point. Externship is definitely (field) experience. We as Career Service professionals need to make sure we are educating our employers to that fact. We also have to explain to our students how to present themselves as having experience when they are speaking with a potential employer. All too often our students lack the confidence on a interview or they don't even go to the interview. We and our instructors need to help the students understand how valuable the extern experience is, and even if they don't get hired on their extern site, how they can use the experience to get another position.
