Comments on twitter indicate that an NDIS "independent assessment", part of its pilot, did not go well.
This is hardly surprising. The NDIA's CEO sent a letter to all NDIS participants claiming "The [NDIA's assessment] tools have been ... used all over the world for many years". There is no such tool for assessing the capability, and more importantly the support needs, of autistic people. There most certainly is no assessment tool for ASD that has been used, and shown to be accurate, "all over the world for many years".
