I am a new head working with a very supportive and active governing body. I have discovered that in my new schoolthere is a history , going back many years, of governors, including parent governors, conducting lesson observations on teachers which includes written feedback including a 'what could have been better' box. This is completely alien to me, the head in my last school would never have allowed this, observing teaching to develop governors' knowledge and understanding, yes, but not assessing teaching. Her argument was always that governors were not professionals in the education world, and that their strategic role was to ensure that monitoring of teaching and learning was being carried out effectively by the SLT. The staff have also raised this issue with me, they are not at all happy about the practice and the union rep has brought up the NASUWT advice on the matter. I'm going to speak to both Governor services and the NAHT tomorrow but I thought I would ask experienced heads here what you thought, and whether this is common practise elsewhere. Many thanks in advance for your advice and comments.
