Group work is assessed based on the quality of the final product, the group's process, and individual contributions. Students may do self and peer assessments to evaluate their own and others' performance. Self and peer assessments give students a chance to reflect on how they worked in a group and get feedback from teammates. WebPA is an online peer assessment system developed at Loughborough University that has been used since 1998 across many departments and by over 2,500 students. It allows team members to grade their own and others' performance, with the grades calculated by the WebPA system.
