Does my child qualify for the NDIS?

"Does my child qualify?" is the question every parent starts with, and the answer is frustratingly nuanced. Two children with the same diagnosis can have different outcomes because eligibility isn't about the label — it's about the functional impact.

The three gates you have to pass through

The NDIS Act sets three eligibility tests. Your child must meet all three to become a scheme participant.

1. 1Age — under 65 when first applying.
2. 2Residency — Australian citizen, permanent resident, or Protected Special Category Visa holder, and resident in Australia.
3. 3Disability OR early intervention requirements — the clinical test, below.

The first two are straightforward. The third is where most of the work happens.

Two paths through the disability test

From here the test splits based on age. Under 9 is simpler; over 9 is stricter.

Path A — Early intervention (typically 0–9)

For a child under 9, the NDIA can accept a child without a named diagnosis if there is documented developmental delay and evidence that early intervention will reduce the child's future need for supports. This is the Early Childhood Approach. The test is:

• The child has an impairment or condition likely to be permanent.
• Early intervention will benefit the child by reducing functional impairment or by preventing deterioration.
• The supports needed are best funded by the NDIS rather than another system (schools, Medicare, hospitals).

Developmental delay is defined in the Act as a delay in cognitive, physical, sensory, social/emotional, communication, or adaptive development that results in substantial reduction in functional capacity, is likely to be permanent, and requires a mix of coordinated supports. In practice, a paediatrician or allied health clinician identifies delay through standardised assessments and observation.

Path B — Disability requirements (typically 9 and over)

For a child 9 or older, or where Path A hasn't applied, the access test is stricter. The child must have:

1. 1An impairment or condition that is permanent, or likely to be permanent.
2. 2That is attributable to one or more of: intellectual, cognitive, neurological, sensory, physical, or psychosocial disability.
3. 3That results in substantially reduced functional capacity to undertake one or more of: communication, social interaction, learning, mobility, self-care, self-management.
4. 4That affects the person's capacity for social and economic participation.
5. 5Requiring supports likely to be needed for the person's lifetime.

The two words that parents always miss here are 'substantially' and 'permanent'. Both do heavy lifting in decisions.

"Substantially reduced" — the word that decides most cases

Substantial means the impact is beyond what a child of the same age would usually experience, and is severe enough that the child needs ongoing support from a person or piece of assistive technology to take part in the activity. Borderline impairment, or impairment a child can independently work around, usually does not meet the threshold.

The NDIA has a 'List A' of conditions where substantial functional impact is presumed — intellectual disability, Level 2 or 3 autism, permanent blindness, severe cerebral palsy. If your child has one of those, the functional test is largely bypassed. For everything else — including Level 1 autism, ADHD, anxiety disorders, and most speech-and-language disorders — the functional impact must be demonstrated.

The diagnoses most parents ask about

Autism

Level 2 and Level 3 autism are on List A — the functional impact is presumed, and evidence is usually straightforward. Level 1 autism requires evidence of substantial functional impairment across at least one domain (typically social interaction, communication, or self-management). An autism diagnosis without functional evidence is not enough for Path B access.

ADHD

ADHD by itself almost never qualifies for NDIS access. This surprises parents — it is a real, disabling condition with real impact on a child's life. But the NDIA position is that ADHD is primarily managed through the health system (paediatrician, medication) and schools (adjustments under the Disability Standards), and therefore is not 'best funded' by the NDIS. Children with ADHD who also have autism, intellectual disability, developmental coordination disorder, anxiety with substantial functional impact, or another qualifying condition usually do qualify on the basis of those co-occurring conditions. ADHD as the sole presenting issue is a hard no in most cases.

Intellectual disability

Intellectual disability with an IQ below approximately 55 is on List A — presumed substantial. Above 55, functional impact must be demonstrated, but these applications are usually successful where there is paediatric evidence of significant adaptive functioning impairment.

Speech and language disorders

Developmental Language Disorder (DLD), severe articulation disorders, and significant expressive/receptive language delays can qualify under Path A in under-9s. Over 9, the test tightens — evidence of substantial impact on learning, communication, and social interaction becomes essential. Standardised language assessment (CELF, PLS) is the cornerstone of evidence.

Anxiety disorders, depression, and complex psychosocial disability

Mental health conditions can qualify under Path B's psychosocial disability category, but only where the condition is enduring (generally more than two years of significant impact), treatment-resistant, and causes substantial functional impairment across multiple domains. For most children with anxiety or depression, Medicare pathways (Mental Health Care Plan, psychology) are the better first-line lane. NDIS access for psychosocial disability in children is uncommon.

Developmental Coordination Disorder (dyspraxia), sensory processing disorder, dyslexia

All three can qualify under Path A in under-9s if the functional impact is well-documented. Over 9, access is harder — schools have responsibility for learning-specific adjustments under the Disability Standards, so NDIS funding usually focuses on life-skills, therapy, and capacity-building rather than academic support.

What the NDIA will NOT accept as the sole basis

Worth naming clearly, so parents don't invest months in an application that won't land.

• A concerned parent's description, without clinical assessment.
• ADHD alone, without a co-occurring qualifying condition and functional impact.
• Anxiety or depression alone in a child who hasn't had sustained treatment attempts first.
• Mild articulation or mild motor delay in a child otherwise meeting milestones.
• Giftedness, even twice-exceptional, where the disability side hasn't been independently established.
• A chronic medical condition (e.g. diabetes, asthma) that is managed through the health system.

Two children, same diagnosis, different outcomes

Worth seeing this clearly: two children with identical autism diagnoses can have different NDIS outcomes. One with Level 2 autism, documented self-regulation difficulties, and significant impact on school and home life will receive a plan. One with Level 1 autism, strong adaptive function, and no documented impact on daily activities may not — or may receive short-term Early Connections rather than an ongoing plan. The scheme funds impact, not diagnosis.
