Don't wish to hijack but just to add my pennyworth in..
I have followed this discussion with interest, and when i googled Stealth dyslexia it felt like the author was specifically writing about DS in parts.
Is it the same thing as DME/ dual or multiple exceptionality, which is what I know ds to be?
My own experience is if the school doesn't want to make provision, then they won't (e.g. Ds's primary school) and if they do want to, then they will (e.g. DS's secondary school). If there is a way of convincing a reluctant school to help, then I never found it.
I did my very best but they just kept batting me away with talk about how he was in the normal range, for somethings and top for others. If I pointed out the gulf between his verbal ability and knowledge and the quality of his written answers, the teacher would revert to the traditional, first line of defense i.e. apply the pushy parent rebuff.
Anyway, I tried everything but got nowhere with the primary school. On the other hand, secondary school were interested in the various specialist reports, did their own tests and enthusiastically took up the baton from there. Its a relief when finally you begin to realise that the school is on the same side...
