Hello all -
Thanks for all your advice and information. I just wanted to update after the PPT meeting.
As expected, they were most uninterested in a careful evaluation of her "average" scores vs. her higher potential, but we did get some traction with her "very low" math scores, and after quibbling a bit about the value of our homeschooling, the group did write up an official IEP for math calculation. They also handed over paperwork to apply for testing accommodations, which was probably our most concrete goal.
Thanks for all the information, and to everyone who read or posted. We can move forward with the testing evaluation to help DD to understand her brain and its potential.
