He said this could be a problem - she's not reading social cues and apparently SHOULD have somehow been uncomfortable in order to not overwhelm the other kids.
Sorry, I have just recently heard of NVLD and don't know much about it, but in reading your post I was just struck by how this guy's evaluation seems off to you as well as very different from what others have said (e.g., the teacher who made the comment about your DD's high EQ). So the tester thought she should have been acting differently--do other kids actually have any issues with her behavior, or did the tester just think they might? It sounds like she gets along with other kids very well, so I too am puzzled by the tester characterizing this as a problem. I guess you've ruled out an earlier diagnosis--does the current tester have experience or credentials that might give his opinion more weight in diagnosing these LDs? Finally (maybe this is because I am naive and also because our DD received multiple diagnoses this year that I think are off-base, but) doesn't it seem odd that your DD was diagnosed with several disorders? I'm starting to think about this after seeing any multiple diagnosis discussed here, at least when two or more of the diagnoses have similar characteristics and particularly unless the tester is experienced with 2e kids--is this tester experienced with gifted and 2e, so that they might be able to sort out the different behaviors? Having read the James Webb Misdiagnosis book, I think a lot of our DD's ADHD/inattentive traits look more like the gifted behaviors he discusses that can mimic ADHD--which of course means they still need to be addressed, but differently. But I guess maybe if it's becoming too hard (or expensive, or time-consuming) for you to sort out what the real diagnosis is, maybe you should consider what you want from a diagnosis (like, are you trying for accommodations at school?) and decide whether it's worth going through more evaluations. Sorry things are so difficult in trying to sort this out

Best of luck,
