[senco-forum] access arrangements

I have some students who qualify for a reader when tested at the end of Year 9, but by the time they sit their GCSEs many of their teachers feel that they no longer need a reader and are coping adequately with exams. 

Does anybody know what is my situation.  At the moment I offer a reader to those who qualify for this access arrangement and if they do not want to take it up I leave the decision to them.  However, if their teachers feel that in Year 11 in the classroom they are coping adequately without a reader can I, as the person responsible for access arrangements, withdraw this from them on the grounds that they are coping adequately in the classroom, in Year 10 exams and Mocks without a reader. My understanding is that the access arrangement should reflect the normal provision for the student in these situations.   

Does anyone have any experience of this.  I need to be standing on firm ground with regard to this.  Many of our parents are quite vociferous.
