I am abandoning Edexcel - I used to teach AQA successfully at previous job, conituned Edexcel at new post for continuity sake and in the belief that the two specs were very similar - but am fed up with diminishing returns. Last year's AS marks were poor mainly due to inexplicable Unit 2 marks, although unit one was lowered by a few marks. This year, Unit 2 still bad but unit one dropped by between 7 and 11 marks across the group. I don't understand why - I've tightened up after last year, been on Chief Examiner courses etc, etc. There is a definite disconnect between my view of how students are doing and how marked. I would like to know if anybody has had similar issues so I can either put in for remarking or accept it's somehow my fault. I've never been impressed with their wishywashy approach - AQA at least are clear in expectations, even if it is death by criteria. Maybe the Edexcel methods of assessment do not suit me or my students. Of course I'm tempted to go back to AQA but I'm willing to look at other boards. I just want to understand what results mean.
