Instructors who lead the student's first class on campus have an important role in setting expectations. It's very important the instructor models professionalism in every aspect of student interaction; this sets the expectation of professionalism for the entire lentgh of the program. Students who follow the instructor's example and 'model' this level of professionalism have a good chance of being successful. Instructors who are rather loose (language, punctuality, dress, etc.) almost set the students up for failure, as the student will have a significantally more difficult time on campus and in the workplace if they 'model' these examples of unprofessional behavior.
