Just to be clear, MON, not to push:
I'm not asserting the value of the school's testing in giving you further info; your private person undoubtedly has a more expert handle on things. But the school may be legally required to evaluate before the 504; they certainly would be in the case of an IEP.
In our experience, the school evaluation meeting is the key opportunity for us to bring forward our own testing and expert witnesses who make our case that the disability is real; their information is then incorporated into the school's evaluation report. It's on that basis that we then negotiate accommodations.
