Who can diagnose global developmental delay?

In Australia, a formal diagnosis of Global Developmental Delay (GDD) must be made by qualified medical professionals. This ensures the diagnosis is recognised for NDIS eligibility and access to support services.

The professionals who can diagnose GDD include:
• Developmental paediatricians
• Paediatric neurologists
• Clinical geneticists (where genetic causes are suspected)

These specialists often work closely with allied health professionals who assess specific developmental domains, such as:
• Speech pathologists – for communication delays
• Occupational therapists – for motor and sensory concerns
• Psychologists – for cognitive and behavioural assessments

While GPs and child health nurses can flag concerns, only specialists can provide a formal diagnosis required for funding and formal therapy access.
