Hi Walter, We also believe that every instructor needs to be working in the field they are teaching. We believe the instructors need to talk about life on the job - the fun part and the challenges. It brings the world of work into the classroom and helps students understand why they are learning certain skills or theories. By the way, we think that the class sessions you refer to and interview training prior to externships aresomething that should be going on throughout the students training. Thanks, Susan
