This Feature of the Student Engagement Framework focuses on how it is important for institutions to aknowldege the remarkable effort and contribution that students make when balancing study, work, other commitments and various representational roles within their institutions.
The 'Representation and Partnership' section of the resource library contains lots of information relating to this.
Two particularly good resources are:
Higher Education Achievement Report (HEAR) - sparqs

sparqs have developed and published guidance on how the role of course reps can be defined by universities to meet the criteria for section 6.1 of HEAR (which relates to extra-curricular activity). It allows for a single but comprehensive way of recording every student's achievement in their university education.
