See 'Alternative forms of formative and summative assessment' in this Handbook for top tips on self- and peer assessment and considerations to apply in a self-assessment form.
See Race (2001) for a useful briefing on self-, peer and group assessment. There is a particularly helpful illustration in the appendix of the processes that can be applied for students to develop ownership of the peer assessment criteria.
