Assessment and Diagnosis in Tasmania

Assessment and diagnosis is best conducted by clinicians with appropriate training and familiarity with autism. A paediatrician, psychiatrist, psychologist, speech pathologist and occupational therapist, or combinations of these clinicians, may be involved in the assessment and diagnosis of autism. The process should involve:

  • Interviews with individuals who know the person from a variety of perspectives
  • Observation of the person in a number of different settings, or inquiry regarding an adult’s characteristics across a variety of settings
  • A history from the family, school and other relevant settings
  • Evidence-based screening tools should be used during both natural and structured observations

The experience of seeking and gaining a diagnosis can vary from person to person. Diagnosis of autism is made on the basis of observed behaviour.

Seeking a diagnostic assessment in Tasmania

Children under 4

Children under the age of 4 who are diagnosed with autism are currently eligible to apply for Helping Children With Autism (HCWA) funding. No new applications for this funding will be accepted after 1 July 2018 due to the expansion of the National Disability Insurance Scheme (NDIS) for children of all ages.

To be eligible to apply for HCWA, diagnosis must be made by a paediatrician, child psychiatrist, or multidisciplinary team. Private allied health professionals may work collaboratively to assess and diagnose autism. In this case, both a psychologist and speech pathologist must be part of the assessment and diagnosis process. State funded multidisciplinary assessment services are provided the Tasmanian Autism Diagnostic Service (TADS) (for children aged 0-18), and StGiles (for preschool-aged children only).

The Raising Children Network provides a good summary of the general process of diagnosis and what to expect when seeking an assessment for your child.

Other age groups

Children over the age of 4 and adults who may seek NDIS funding in the future, should consider the NDIS operational guidelines regarding access. Specifically, ‘autism diagnosed by a specialist multi-disciplinary team, paediatrician, psychiatrist or clinical psychologist experienced in the assessment of Pervasive Developmental Disorders, and assessed using the current Diagnostic and Statistical Manual of Mental Disorders (DSM-V) diagnostic criteria’.

Children under the age of 13 may be eligible for Medicare rebates if referred by paediatrician or psychiatrist under the ‘Helping Children with Autism Program: Access to Diagnosis’ plan. Allied health professionals must be registered for Medicare in order for a claim to be made. For details, see the Department of Health’s HCWA information page.
