This post has been posted in maths but I feel it is more suitable here. In each school the HT is ultimately accountable for the outcome of GCSE Results each August. If the results don't stack up in individual subjects and especially in English and Mathematics then the subject leaders and the class teachers get it in the neck. Subject Leaders get paid less than Leadership so where is the level of accountability for deputies and assistant heads who line manage the subject leaders etc, when the results don't stack up. It would be interesting to find out the level of accountability in your SLT and if you are SLT, do you feel and/or are you made accountable?
