Lots of people have given lots of good advice, so I have really only one thing to add:

Federal case law states that grades may not be used as a disqualifier for offering services: that is, if a child has a disability, the fact that they are an A student does not mean they cannot benefit from remediation, and it must be offered. Especially with gifted kids, being an A student is an indicator that they are finding work-arounds and ways of getting past the disability, not that it is being ameliorated. The key phrase is "adversely affecting a child's educational performance"-- which encompasses more than just marks.

I believe the case in point is LI vs Maine SAD 55, US Court of Appeals, First District. Here's the case link: http://www.ca1.uscourts.gov/pdf.opinions/06-1368-01A.pdf

I've found that referring to case law when talking to the LEA rep tends to get their attention quite satisfactorily.
