I see from various documents on the NDIS website that a person with autism spectrum disorder (ASD), as well as needing evidence of a formal diagnosis, also needs a "severity level" ... or the NDIS will make its own functional assessment to determine his severity level. As my son's diagnosis was done before there were severity levels associated with ASD diagnoses, I expect he will need an NDIS functional assessment to determine his severity level.

Please can you provide details of:

• who will do his functional assessment (what qualifications, skills and/or experience is required for this role)?
• what assessment tool/instrument is used in the process?
• how long does it take to get an NDIS functional assessment?
• how are NDIS functional assessments funded?
