Evidence of your disability

Evidence of your disability: What to provide with your Access Request

To allow the National Disability Insurance Agency to determine whether you meet the disability or early intervention access requirements, you may need to provide us with evidence of your disability. This includes information on what your disability is, how long it will last and its impact on your life.

You can provide evidence of your disability by having your treating doctor or specialist complete the Professional’s Report section in Part F of the Access Request Form, the NDIS Supporting Evidence Form or you can provide the same evidence in a different format, such as copies of existing assessments and reports. You may be able to request copies of your medical diagnosis and/or medical assessments from Centrelink or your current service provider.

If you choose not to use the Professional’s Report section in Part F of the Access Request Form or the NDIS Supporting Evidence Form, it is important that you make sure the information you provide contains the same information that the form collects.

If you are not sure whether you have enough information to support your access request, or you have trouble getting the information, we may be able to help you. See below for information on how to contact us.


You must provide us with evidence of the diagnosis of your disability from your treating doctor or specialist.

Part F of the Access Request Form and the NDIS Supporting Evidence Form collects this information, or you can give us other written evidence of your diagnosis from your treating doctor or specialist. This information needs to include information about any treatment/s you are receiving.

Evidence of the impact of your condition

If you have a condition we have already identified as always resulting in permanent impairment and substantially reduced functional capacity, then we do not require any further information. A list of these conditions is further down this page.

If your condition is not on the list of ‘Permanent impairment/functional capacity – no further assessment required’ you must provide evidence of the impact of your condition on your life, including any impact on your mobility, communication, social interaction, learning, self-care and self-management.

You can provide this information by getting your specialist or an allied health professional to complete the Professional’s Report section in Part F of the Access Request Form, the NDIS Supporting Evidence Form or you can provide us with other written evidence from your specialist or a health professional.

‘Health professional’ includes a physiotherapist, an occupational therapist, speech pathologist, psychologist or a nurse.

‘Other written evidence’ could include existing assessments or reports which were prepared by a specialist or allied health professional that provide the equivalent information on the impact of your condition on your life.

Submitting evidence

The evidence about your disability must be submitted with you access request when required by the NDIA. Your access request will not be considered complete unless we have received all the information we need from you. We will use the information about your disability to help us in determine whether you can become a participant in the NDIS.
