Adult ADHD and Autism (ASD) Assessments
Assessments that empower and illuminate
A trauma-informed, neuroaffirming assessment process where your lived experience is taken seriously. We help you make sense of what’s been happening and identify practical next steps you can use right away.
A calm place to start
For many of us, the hardest part is starting.
You might feel overwhelmed, doubtful, or exhausted from years of pushing through. We slow it down, listen carefully, and build a clear picture together at a pace that makes sense to you.
Why people seek assessment as adults
Many people seek assessment because something is not adding up.
You might want clarity, language for your experience, and guidance on what to do next. Some people need documentation. Most people want understanding that leads to real change.
-
This can include
a clearer explanation for lifelong patterns
relief from constant self-doubt and overthinking
insight into why things take so much effort
a practical path forward that fits how you function
recommendations for work, relationships, wellbeing, and daily life
tools to reduce burnout cycles and live more sustainably
support to address mental health and wellbeing impacts that may have accumulated before assessment was even on the radar
Our special focus: complex adult presentations
Does this story sound familiar? Years of masking, burnout, trauma, or being told you are “fine” while nobody realises how much you are privately struggling. Bills get missed, email inboxes pile up, projects stay unfinished, and future demands feel unbearable. You might find yourself scrolling, procrastinating, or getting stuck in looping thoughts that say you have to keep pushing through, or people will be disappointed, frustrated, or leave.
This can show up everywhere. School. Work. Study. Relationships. You feel worse over time, the demands keep coming, and there never seems to be enough energy to do what life requires. You might have tried support or medication for anxiety or depression, but still feel flat, overwhelmed, or no clearer about what is really going on. Some days, it’s hard to get out of bed.
-
This is where our approach is often most helpful. We often see that capable, caring, high-effort people are especially vulnerable to autistic burnout, and that burnout can look like anxiety or depression when the neurodevelopmental picture has been missed.
We work carefully with complex and overlapping presentations, including ADHD and autism, anxiety and depression, learning differences (such as dyslexia or dysgraphia), trauma, and substance use or other addictions. Once we understand how your system fits together, we can help you adjust your supports and daily structure to protect your energy, lean into your strengths, and get the right help in the places it will matter most.
-
Two clinicians divide the assessment components to build a robust picture, especially when masking, burnout, trauma, or complexity are present.
-
We consider internal experience and the cost of coping, not only what others can see.
-
Our adult ASD assessments include pre-screening questionnaires (completed at home), ADOS-2 (Module 4), structured clinical interviews, developmental history gathering, and psychometric screening.
-
You receive a comprehensive report with clear diagnostic reasoning and practical recommendations.
What makes our assessments different
Many adult assessments can feel rushed or disconnected from real life. Our approach is different:
Our assessments are delivered by an experienced multidisciplinary team, including an Accredited Mental Health Social Worker and a Mental Health Occupational Therapist. With your consent, we can liaise with your GP, psychiatrist, or other treating providers where helpful.
Assessment options
Adult ADHD Assessments
For adults seeking clarity around attention and executive functioning, including drifting focus, mental fatigue, time blindness, working memory, procrastination and task initiation, impulsivity or restlessness, and the ways these patterns can quietly impact work, relationships, self-confidence, and wellbeing.
Medication can only be prescribed by an appropriately qualified medical practitioner.
Investment: $1,320 (Medicare rebates may apply. Payment plans available.)
-
Go directly to a prescriber (e.g., a psychiatrist)
This may be the most efficient option if:your main goal is a medication trial
your presentation feels straightforward
your mental health is relatively stable
you already have a clear history of symptoms since childhood and current functional impact
Your GP can refer you to a psychiatrist. They will confirm diagnosis and advise on medication if indicated.
-
TRC Comprehensive ADHD Assessment (our service)
This is often the best fit if the picture is complex, or you want more than a “yes/no” outcome.It can be especially helpful if:
trauma, burnout, anxiety/depression, sleep disruption, or emotional dysregulation are present
you are high-masking or have spent years compensating
you have been misdiagnosed or dismissed in the past
you suspect autism as well as ADHD
you want practical recommendations alongside diagnostic clarification
We provide an evidence-informed assessment and a detailed report to support next steps.
Not sure which pathway fits? If you enquire, we can help you choose the most suitable option based on your goals and what will be most efficient and safe.
Which ADHD pathway is right for you?
There is more than one way to pursue an adult ADHD diagnosis and medication in Western Australia. The right pathway depends on what you need most right now.
Adult ASD Assessments
A respectful, masking-aware process for adults seeking clarity around autistic presentation, lived experience, identity, and support needs, especially when experiences have been missed due to masking, burnout, trauma, or complexity.
Our adult ASD assessments include ADOS-2 (Module 4), alongside structured clinical interviews, developmental history gathering, and psychometric screening. Reports include clear diagnostic reasoning and practical recommendations.
Investment: $2,100 (Medicare rebates may apply. Payment plans available.)
Comprehensive Psychological Assessments
A broader exploration of psychological functioning to clarify presentation, identify support needs, and inform treatment and planning. These assessments can assist with screening for employment purposes, evaluating fitness for active service, evaluating the impact of a workplace stressor, and identifying whether moral injury, burnout, or trauma may be present. With appropriate consent, the report can be supplied to a third party on your behalf (e.g., a superannuation fund, employer, GP, or other relevant party).
Investment: $965.00 (Medicare rebates may apply. Payment plans available.)
Current processing times (reports)
ADHD: current processing time is approximately 10 business days from the intake appointment

Frequently Asked Questions:
-
Appointments required for assessment, screening tools as relevant, interpretation and formulation, and a written report with practical recommendations. With consent, we can liaise with your existing providers where helpful.
-
These assessments are for adults seeking clearer understanding of ADHD and/or autistic patterns, diagnostic clarity where appropriate, and practical recommendations for support. Some people also need documentation to support planning, workplace adjustments, or funding pathways.
-
Medicare rebates may be available depending on the clinician you see and the referral pathway you use, such as a Mental Health Treatment Plan or Chronic Disease Management Plan. If you are unsure, ask us and we can clarify what applies in your situation.
-
We do not reduce people to paperwork. Our assessments aim to be clinically robust while still honouring the person behind the report. We are trauma-informed, neuroaffirming, masking-aware, and focused on practical recommendations that support real-life outcomes.
-
For us, “trauma-informed” is the front door. It’s the starting place. Every practitioner has a legal and ethical duty to provide trauma-informed care, and we do that too.
But we take it a step further. Our approach is neuroaffirming.
What does that mean? It means you are treated as the expert in your own life. It means we recognise that your efforts, good intent, giftedness, values, and priorities may have been organised around survival rather than around your unique offerings.
We work with you to gently dismantle the dominant narratives you may have absorbed over time, that you are “broken”, “lazy”, “unmotivated” (or whatever other harmful labels you’ve been given). We help you see how your neurodiverse strengths and abilities have been supporting you all along.
Time after time, we see people’s eyes light up when they realise they were given the wrong manual for their system, and they thought the problem was them. We work with you to update your “manual for life” so you can recover from burnout, rebuild self-trust, and move forward with more clarity and confidence.
-
We take masking seriously and explore internal experience, compensatory strategies, and burnout patterns alongside observable functioning.
-
This worry is common. We consider patterns over time, including the effort it takes to function, not only what others can see.
-
For many adults, yes. Understanding your neurotype can reduce self-blame, make past patterns make sense, and support better decisions about work, relationships, energy, and wellbeing. If you are unsure, we are happy to talk it through with you. We will not recommend a full assessment if it is unlikely to be helpful.
-
It’s thorough, paced appropriately, and takes a whole-of-person approach. We consider the factors that shape your day-to-day experience, including your environment, relationships, work and study demands, and psychological wellbeing, and we provide clear reasoning and recommendations that translate into practical, real-life support.
