Having just read Leveller's response (which appeared while I was typing mine), I can only say that this is a common problem with online forums.

People tend to speak as they find from their own experience, as few have the time or inclination to do wide-ranging research into what goes on in the big picture before posting.

My daughter (although not dyslexic) suffered in much the same way as Lizzie's did, and for the same reasons (schools being obsessed with targets and trying to force square pegs into round holes).

I was lucky with my education - I was nagged for being poor at maths and science(being good at English, I apparently should have been good at everything else too), but didn't come under the sort of pressure to achieve that I see now being applied in schools.
