When you have an exceptional child, there are only so many things the schools can do. They, by necessity, have to take a one-size-fits-most approach. Determined parental prodding can get a lot more out of them than would otherwise been had, but there is still a lot that parents have to do to help their atypical kids function in this time and place.
I don't know a lot about dyslexia, either as a trait or how the schools handle it. Do they do IEPs for dyslexic kids? I don't think there is a lot of awareness or much of a support base for it, is there?
