The six functional domains of the NDIS (mobility, communication, social interaction, self-management, learning and self-care) aim to capture how a disability affects all aspects of a patient's life. The website describes who can provide evidence of a functional disability in relation to the six areas listed in the NDIS Act and which evaluations are considered best practices for a range of disabilities. I suspect that these guidelines often did not include participants, potential participants or vendors. For example, the professions that the NDIA considers most appropriate to demonstrate a psychosocial disability are those of psychiatrists, general practitioners (general practitioners), psychologists (in limited circumstances) and some others.
The NDIA then provides a list of standardized evaluations in order of preference to be performed by the treating health professional. Another example is hearing impairment, in which the treating professional appears on the list as an audiologist and, again, is followed by a list of evaluations in order of preference. Article 24 of the NDIS Act lists the disability requirements that a person of at least seven years of age must meet in order to access the NDIS.
