Have you always felt different - but never had a clear explanation?
This assessment is designed to provide a clear, structured understanding of your patterns, and whether autism may be contributing.
✔ Clarify whether autism is present
✔ Understand how your patterns show up in daily life
✔ Know what supports or next steps may be helpful
This assessment may be relevant if you:
have always felt different in social situations
find social interaction effortful, confusing, or draining
prefer structure, predictability, or routine
feel overwhelmed by change or uncertainty
experience sensory sensitivities (e.g. noise, light, textures)
tend to think in detailed, systematic, or highly focused ways
feel capable in some areas, but consistently challenged in others
have questioned whether autism may explain your experiences
Who this is for
Why many adults seek assessment later in life
Many people reach adulthood without a clear explanation for their experiences.
You may have:
learned to adapt or “mask” in social situations
been seen as shy, anxious, or overly sensitive
developed ways of coping that others don’t see
spent years trying to understand why things feel more effortful
felt different, but unable to clearly explain how or why
Without a structured assessment, these patterns often remain:
unclear
misunderstood
or attributed to something else
What this assessment provides
This is a comprehensive psychological assessment designed to explore whether autism may be present and how it is showing up in your life.
Adult assessment is detailed work, so it's spread across several appointments rather than one or two. Your assessment typically involves [three] telehealth appointments, plus questionnaires completed by you and, where possible, someone who knows you well or knew you as a child.
Your assessment includes:
validated questionnaires for you and your informant(s)
a structured clinical interview covering developmental history, social communication, sensory experiences and everyday functioning
integration and formulation of all the information gathered
a feedback appointment to talk through the outcome
a diagnostic letter stating whether diagnostic criteria for autism are met
Optional: comprehensive written report
The diagnostic letter confirms the outcome. A written report explains it: how the criteria are met, how your patterns relate to your day-to-day functioning, and recommendations for supports or adjustments.
A report can be useful for:
NDIS applications
workplace or study adjustments
sharing with your GP, psychiatrist or other professionals
a clearer framework for understanding yourself moving forward
If you're applying for funding, adjustments or support, check what that pathway requires before you book. You can also add the report later.
Please note that acceptance of letters and reports may vary depending on the requirements of the receiving professional or organisation.
What happens after the assessment
Where appropriate, your report may:
provide diagnostic clarification
support discussion with a GP, psychiatrist, or other professionals
help you understand your needs in work, study, or daily life
inform support planning or adjustments where relevant
What’s involved
Step 1: Pre-assessment measures
You will complete validated questionnaires assessing social communication, behavioural patterns, and related areas. Your informant(s) will complete their own.
Step 2: Clinical interview
A structured interview exploring developmental history, social communication, sensory experiences, and how these patterns show up in everyday life.
Step 3: Feedback and diagnostic letter
We meet to talk through the outcome, and you receive your diagnostic letter.
Optional Step 4: Written report
If you've chosen a report, it's provided approximately two weeks after all questionnaires have been returned.
