It looks like they might be writing a cookie cutter GIEP to fit their program instead of writing an individual document to fit your child's individual needs.
In your document, is there a "Current Levels" or similarly themed section? In your opinion, is it complete as to current grade levels for different classes, leadership skills, etc? IMO, if the current levels section is done very well, the school often has no reasonable choice but to address them (once you point it out).
If it is not complete, request that they add information (and possibly do testing, not just IQ) until it is complete.
