Building Evidence to Support Your NDIS Plan
How to gather strong evidence for your NDIS plan — what counts, who writes it, and how to organise it before a reassessment or review.
Strong evidence for your NDIS plan is simply proof of two things: what your disability-related support needs are, and why the supports you are asking for are reasonable and necessary. The National Disability Insurance Agency (NDIA) — the government body that runs the NDIS — makes funding decisions from the information in front of it, so the quality of that information matters.

Frequently asked questions
How recent does my evidence need to be for an NDIS plan?
There is no single official expiry date, but recent evidence carries more weight than old evidence, especially if your situation has changed. As a rule of thumb, aim for reports that reflect your current function. If your needs have shifted since your last report, get an updated one before a…
Does a diagnosis letter on its own prove my support needs?
Usually not. A diagnosis helps establish eligibility, but the NDIA funds supports based on how your disability affects your daily life — your function — not the diagnosis alone. The strongest evidence pairs the diagnosis with functional assessments and reports that explain what support you need, how…
Can I use my own words as evidence, or does it all have to come from professionals?
Your own account absolutely counts and is valuable. A clear description of a typical day, and a bad day, grounds the clinical reports in real life and captures detail an assessment can miss. Clinical reports from allied health professionals usually carry the most weight, but your voice and a carer's…
What happens to my evidence under the new assessment from 2027?
From 1 April 2027 a trained assessor will progressively evaluate functional capacity and support needs using a standardised tool. You cannot sit it early, but keeping current, consistent evidence helps ensure the assessment reflects your real needs rather than a single snapshot. Timing is staged and…
Who pays for the reports I need for my plan?
It varies. Some allied health assessments can be funded from your existing plan, and reports written as part of ongoing therapy are often included in sessions you already fund. Specialist and GP letters usually go through the health system. Ask the clinician for a quote up front and check with your…
