WebPA is a peer assessment tool that you can access from duo.
This video provides an overview of it:

Note that it is not a tool for creating submission points. Rather, it is a tool that students can use to assess the contribution of their peers (and optionally, themselves) in any group-based activity.

The first thing to get your head around is whether you want to perform peer feedback or peer assessment. David Nichols from Strathclyde University has written extensively on this. Peer feedback involves comments, but no grading. Peer assessment alters the final marks students receive, and is often used for group work. As the name suggests, WebPA only supports peer assessment. If you want to carry out peer feedback, contact a member of the LTT for more details.
