Oh, and it occurs to me that DD does not have dyslexia because her vocabulary comprehension is not impaired, right?
This is quick because I don't have much time at the moment, so I hope it makes sense!
There is "dyslexia" and there are "reading challenges". Dyslexia has a traditional definition based on a checklist of abilities-vs-challenges that can be easily marked off yes/no in an evaluation - and those evaluations are fairly standard - but they don't include a host of other issues that might cause a student to struggle with reading. So a reading challenge might be dyslexia or it might be something else. Whatever it is, you need to find a way to teach your child to read and to accommodate what needs to be accommodated... sooo... the goal as I see it with reading challenges isn't an on/off switch for is it or isn't it dyslexia.
It also gets confusing because some professionals refer to dyslexia (the diagnosis) in a very narrow sense, as it's been officially defined), while others include a wider range of challenges when using the term. My dd has a dyslexia diagnosis from a reading specialist, and a report from another professional clearly stating that she does *not* have dyslexia. Yet both found the same actual challenge (inability to link/retain visual symbols to sound).
