Getting responsibility from peers is a lovely feeling. It shows that they have confidence on you to represent them. And my class chose someone who is a little quiet, but a listener at the same time. Or that's what I think they think of me. Except for one person who decided to say, before they voted the Class Rep, that we shouldn't vote someone who would stand in the corner behind the door and say nothing. Shows what he knows.
A good class rep has the capability to listen, take on board what has been said to them and relay the concerns to the Staff and heads of department. A Class Rep is also the line of communication between the Staff and Students. That link is there to make little changes to teh learning environment. Be it, a timetable on the doors of the computer labs or posting CA deadlines on the notice board. Small things which help everyone in a little way to make life easier.
In the Meetings time is given to each person, reasons and answers are given to the queries, discussion and improvements are written down with intention to correct them where possible. I now see the benefit of the Class Rep System. I dunno if it worked as well in the secondary school system, but it sounds like it works in Third Level...
