Our school has just adopted a system whereby all teachers are to be observed by a group of students once a year. This is, according to the literature, that has been disseminated is to see whether "students" are doing what they are supposed to be doing in lessons and following certain school initiatives. Thye have also been "trained" to be able to carry out these obs. The feedback from the lessons is given to the teacher in question and also to a member of SLT. We already have termly observations for appraisal (one hour), plus learnings walk three times a years (30 mins and feedback given), marking and feedback scrutiny for all years groups (so twice a term) and student surveys per year groups (once every half term therefore). And now this!!!
