Building Strong Evidence for Your Plan
What good NDIS evidence looks like, how to gather it, how to keep it current and the common gaps to avoid — a calm, practical guide for participants.

Good evidence is not about having the thickest folder — it is about having the right information, described clearly and kept current. This guide explains what strong evidence looks like, how to gather it, and the common gaps that catch people out.

Frequently asked questions
What makes NDIS evidence strong?
Strong evidence describes your functional impact — how your disability affects everyday activities — rather than just naming a diagnosis. It is current, specific with real examples, and comes from professionals who know your situation. Quality and relevance matter far more than the number of…

Keep copies together in one folder, physical or digital, and add a short cover summary of your diagnoses, the professionals involved, and a plain-language description of your typical and hardest days. Organised, current evidence makes the assessor's job easier and reduces the risk of things being…
