What NDIS Assessors Are Looking For
What NDIS assessors look for — functional impact across life domains, permanence and reasonable and necessary supports — and why honesty matters.
Walking into an assessment is far less nerve-wracking when you understand what the assessor is actually trying to work out. They are not judging you or looking for reasons to say no. They are building a picture of how your disability affects your life. This guide explains what that picture is made of — functional impact, permanence and the reasonable and necessary test — and why honesty about your…

Frequently asked questions
What is the main thing NDIS assessors look at?
Functional impact — the difference your disability makes to everyday life across domains like mobility, communication, self-care, learning, social interaction and self-management. They focus on how you actually function day to day, rather than on your diagnosis alone.
Does a diagnosis guarantee NDIS support?
No. A diagnosis is part of the picture, but assessors look at functional impact and permanence, not the label by itself. Two people with the same diagnosis can have very different needs, so the assessment focuses on how your disability affects your everyday life.
What does 'reasonable and necessary' mean?
In everyday terms, it asks whether a support is genuinely related to your disability, helps you pursue your goals and take part in daily life, represents good value, and is the kind of thing the NDIS is meant to fund. Linking your supports to your functional impact and goals helps show this.
Why is being honest about bad days so important?
Because a picture built only on your good days leads to a plan that covers only your good days. Your hardest days are just as real and relevant. Describing them honestly, including how often they happen and the help you need, completes the picture — it is not exaggerating.
Should I mention the help my family already gives me?
Yes. Include the informal help you rely on when describing your function. If a task is only possible because someone assists you, leaving that out makes you appear more independent than you are, and the plan may not reflect your real needs.
Is more evidence always better?
Not necessarily. Quality matters more than volume. Current, specific evidence that describes your functional impact is more useful than a thick file of old letters that only list a diagnosis. Our guide Building Strong Evidence for Your Plan explains what strong evidence looks like.
