I teach a modular program, so a few students are always completing their education as new students are coming aboard. I find the students who've been through the program, or have been in it longer, have established their own type of peer pressure. They are constantly asking the other students how they will proceed once out of school, and encourage them to take the national exams in addition to receiving their state license. They even "pressured" my new co-instructor to take her national exams. Seeing all of the success of these students has driven some of the newer ones to want the same success. I find they do most of the motivating, and I do more of the reassuring of those not quite confident enough in their own ability. It works well for our group, so I'm content to provide support to those people that aren't sure of themselves, and let the cohorts do some of the motivating.
