You might want to check
www.wrightslaw.com for some info on how to approach the issue of the school doing their own testing which basically duplicates what's already been done. I know that IDEA addresses this issue and at the very least encourages schools to use already available testing versus putting students through repeated testing (which can essentially stall the process and skew the results for a different outcome).
I agree that an advocate would be helpful. Do you have any resources for contacting someone?
