The real reason why too many children aren't reading properly

A report today by the charity Xtraordinary People claims that the reason 20% of youngsters don't make the grade in national tests is because half of them are dyslexic. That may indeed be the reason, and I'm all in favour of better diagnosis earlier. But isn't it just as plausible that the failure of a quarter of schools to introduce phonics yet, as indicated in Sir Jim Rose's report today, might be as much to blame?
