ASD Assessment

An autism spectrum disorder (ASD) assessment is a diagnostic assessment
to determine whether an individual’s developmental profile and presentation meets the criteria for a diagnosis of ASD.

We offer assessments from approximately 18 months of age through to adulthood. A referral from a paediatrician is required for all children and adolescents up to the age of 18 years. Adults can self-refer for assessment.

The process involves one face-to-face session.

For adult assessments, the individual will complete a series of questionnaires before the assessment. A parent may be asked to complete a brief developmental history questionnaire, if appropriate. On the day of the assessment, the speech therapist and psychologist will complete a diagnostic interview with the individual. The individual may be asked to bring in old school reports and photos from their childhood. This session may take up to 2 to 2.5 hours.
For children, a comprehensive developmental history will be completed with the parent by the speech therapist while the child completes the ADOS-2 with the psychologist. When the ADOS-2 is complete, the psychologist will finish the developmental history and the speech pathologist will complete social communication assessments. This session may take up to 2 to 2.5 hours.

After this session, the assessors will score all assessments, review developmental history and observations, review past reports, liaise with other therapists (if necessary) and paediatrician (for individuals under 18).

A comprehensive report including reported information,
observations, assessment results, a comprehensive needs assessment
and recommendations is developed.

A feedback session is scheduled which is completed over the phone.
The assessors will provide a draft report for the feedback session and will go through the outcome of the assessments, the layout of the report, recommendations and answer any questions parents / caregivers / individuals may have.

A draft report is provided to enable parents / caregivers / individuals to read through and ensure all reported information has been documented correctly. The assessors will then provide a final copy of the report.

The assessors aim to complete the draft report and feedback session within 4-6 weeks post-assessment.
