Peer assessment can help hone students’ feedback skills, improve teamwork, and increase collaboration.
Peer assessment of other students' assignments
This refers to students providing feedback on other students' assignments to help them improve their work. This feedback may or may not involve a grade. When properly implemented, PA can be a reliable and valid method of assessment.
Peer assessment of contributions to teamwork

PA of teamwork has the potential not only to mitigate challenges associated with students working in groups, such as “social loafing,” but also develop students’ collaboration and negotiation skills.
