Keet, I'd think that legible handwriting is only part of it-- they'd also have to show that he doesn't tire or lose accuracy (more than peers) in long writing tasks.

Do you have an outside expert to consult?

I don't think there's anything "automatic" about qualifying for an IEP; certainly most schools seem to dismiss the discrepancy model out of hand these days. You'd have to prove that the disability continues to have an impact on his ability to participate in his education.
