Understanding NDIS eligibility for intellectual disability
If you are supporting a person with an intellectual disability, you can access NDIS funding and supports.
You can access the NDIS if you meet the required criteria.
To get started, you need to meet three key requirements.
NDIS eligibility criteria
1. Age
You must be between 9 and 65 years old at the time of applying.
2. Residency
You must live in Australia and be:
- an Australian citizen
- a permanent resident
- or a Protected Special Category Visa holder
3. Disability requirements
Your disability must be permanent and impact everyday life.
For intellectual disability, this includes challenges with:
- communication
- learning
- social interaction
- self-care
- decision-making
The NDIS looks at functional impact, not just diagnosis.
Check your NDIS eligibility
Before you apply, do a quick check using the official NDIS tool:

What the NDIS needs to see
Every application is assessed on two things:
- The diagnosis
- The impact on daily life
Both must be clear.
For example:
- Not just “intellectual disability”
- But how it affects your daily life, communication, managing money, or social interaction
This is what strengthens an application.
Why functional capacity matters to the NDIS
The NDIS does not fund based on diagnosis alone.
What matters is how your disability affects your daily life.
This has now been clearly reinforced in recent NDIS reforms. NDIS Minister Mark Butler announced in a press release on 22 April 2026 that the scheme is moving away from a “diagnosis gateway” and returning to its original focus on functional capacity and support needs.
This means your eligibility and funding are based on how your disability impacts your ability to function day to day.
Two people with the same diagnosis can receive different outcomes. This is because the NDIS looks at how each person manages areas like communication, learning, self-care, and independence.
As part of these changes, a new standardised assessment approach will be introduced to better measure functional capacity across participants.
Evidence for intellectual disability
Your evidence must come from a treating health professional who understands the participant.
This can include:
- Paediatrician
- Psychologist
- Occupational Therapist
- Speech Therapist
Best practice assessments
The NDIS prefers structured assessments like:
- DSM-5 diagnosis
- Vineland Adaptive Behavior Scale (Vineland-II)
- WHODAS 2.0 (17 years and over)
- PEDI-CAT (16 years and under)
Your reports should clearly explain:
- the diagnosis
- that it is permanent
- how it affects everyday functioning
- current supports and needs
