Social communication, development and behaviour
Autism Assessment
A respectful, evidence-based assessment for children, adolescents or adults with questions about social communication and restricted or repetitive patterns of behaviour, interests or activities.

Who it may help
Questions this pathway can explore.
- 01
Children or adolescents with developmental or social-communication concerns
- 02
Adults seeking a first diagnosis or understanding of longstanding differences
- 03
People whose presentation may be subtle, highly verbal or shaped by masking
What is involved
A thorough, tailored assessment.
The exact battery is confirmed after intake so that assessment remains relevant to the person and the reason for referral.
- The ADI-R: a detailed developmental interview with a parent, carer or other suitable informant
- The ADOS-2: a standardised, activity- or conversation-based observation with the client
- ABAS-3 questionnaires about everyday practical, social and communication skills
- Scoring against recognised diagnostic criteria, an individualised report and a feedback session
Clinical context
Understanding autism
Autism is a lifelong neurodevelopmental difference that can affect social communication and interaction, sensory experience, interests, behaviour and a preference for routine or predictability.
There is no single medical test for autism. Assessment combines developmental history with direct, structured observation and considers the person’s context, strengths, support needs and the ways they may mask or camouflage traits.
What you receive
Findings made useful.
A written report explaining whether the presentation meets diagnostic criteria for autism, describing relevant support needs and the person’s social-communication, behavioural and adaptive-functioning profile.
Potential benefits
- An evidence-based, individualised profile of strengths and support needs
- Greater self-understanding and a shared framework for families and professionals
- Recommendations for school, work, home and allied-health support
- Diagnostic documentation where criteria are met
Important to know
A balanced view before you proceed.
- 01
The developmental interview can be emotionally significant for the person and their family.
- 02
Findings reflect information and presentation across the assessment period; masking, fatigue or an unfamiliar setting can influence what is observed.
- 03
Co-occurring ADHD, anxiety and learning differences are common and are considered as part of the clinical picture.
- 04
A diagnosis does not automatically guarantee NDIS access; eligibility also depends on evidence of functional impact and support needs.
- 05
An assessment does not guarantee a diagnosis, funding or accommodations.
Using the report
Designed to support practical next steps.
Reports can assist different conversations depending on the findings, the person’s circumstances and the requirements of the receiving organisation.
