How is Autism Spectrum Disorder assessed and diagnosed?

Diagnosing a child with an Autism Spectrum Disorder involves three stages: Screening; Assessment; and, Feedback and Report.
The assessment team uses information gathered from parents, doctors, therapists and teachers, as well as their own observations in the child’s home/kindergarten/childcare, and during the formal assessment
A diagnosis is formulated after consultation with the child’s paediatrician. Families are then given feedback about the diagnosis.

What does an ASD assessment involve?

ASD is diagnosed by examining the child’s development and behaviour. Sometimes ASD can be difficult to diagnose so it is important to have a comprehensive assessment to distinguish ASD from a range of other difficulties.

An assessment by a paediatrician is required prior to an assessment for ASD in order to rule out other factors including medical conditions that may be affecting the child’s development and behaviour. A hearing assessment may also be required.

If other assessments have also been completed, such as a speech assessment, this information is also considered in making a diagnosis.
Sometimes it is clear from the initial information that the child does not have ASD. If it seems that the child might have ASD, the Gateways Autism Assessment Team will discuss the child’s early development and behaviour with the family.

Information is also gathered about the child’s current development and behaviour to complete a full picture of their day-to-day functioning and interactions in various situations. Often a specialised assessment is undertaken to determine the child’s range of skills and abilities.

All of this information is considered in consultation with the child’s paediatrician before in arriving at a decision about whether the child has Autism Spectrum Disorder or some other communication, behavioural or developmental difficulty.

After the assessment, a follow up session is arranged with the family to: discuss the outcomes of the assessment; provide information; and, discuss available service options.

A written assessment report is then completed and provided to the family. Copies of the report can also be provided to other professionals with the family’s permission.
