Importance of Disability Evidence

Disability evidence is essential for determining eligibility and planning supports under the NDIS. The evidence provided must clearly outline the nature of the disability, its functional impact, and any specific needs of the individual. Health professionals play a critical role in documenting this evidence to ensure participants can access the best supports available.
