The Neurodevelopmental Disability Assessment Service (NDAS) is a government service. It is run by the Department of Communities. NDAS provides assessments for autism and intellectual disability.
These assessments help to understand how a person learns, thinks, communicates, and experiences the world. This helps families, carers, and support networks to identify the right supports to help the person to live, learn and thrive in their everyday life.
Autism spectrum disorder (ASD) assessments
NDAS assesses children and young people up to 17 years of age for autism.
To access this service, a referral must be provided by a paediatrician or a child psychiatrist.
Intellectual Disability (ID) assessments
NDAS assesses both children and adults for intellectual disability when there is a strong reason to do so and when NDAS is the most suitable service.
Referrals for intellectual disability assessment can be provided by different people, but it is best if they come from a doctor or an allied health professional who knows the person well.
