Class Representatives (see ANU Policy and Procedure) are students in the course that represent the student cohort in that class to the conveners and the university administration. They provide the conveners with feedback about how the course is going, and can relay concerns, complaints, and other comments from students who do not wish to bring these to the conveners directly.
If you are enrolled in the course and would like to serve as a class representative, please e-mail the course conveners (it also does not hurt to talk to them at the workshops). The role entails meeting with the conveners, and separately with the Associate Director (Education), and having your contact data put on Wattle to be accessible to the rest of the class (and through that, talking to your fellow students), as well as your name (and if you like, photo and short bio) here on the course website.
