This paper reviews research from the field of language teaching into post observation feedback i.e. the discussion that takes place after an observer has watched a pre-service or in-service teacher’s lesson. Post observation feedback is discussed with reference to four main themes: (1) perceptions of feedback; (2) reflection; (3) relationships (with two sub-themes of identity and facework); and (4) observer training. This review indicates that while the fields of language teaching and applied linguistics are leading research into post observation feedback, there remains important and interesting avenues for future research, which are discussed in this paper.
