ADHD Assessment in Australia — What to Expect & How to Book
If you suspect you or your child may have ADHD, a formal assessment is the way to get a clear answer. It’s a structured process — not a single test, but a combination of interviews, questionnaires, and sometimes cognitive testing — designed to determine whether ADHD accounts for the difficulties you’re experiencing, and to rule out other possible explanations.
This page covers what an ADHD assessment involves, who it’s for, what it typically costs, and how to prepare, so you know what to expect before booking.
The process
What does an ADHD assessment involve?
- Clinical interview
- A detailed conversation covering current difficulties, developmental history, and how symptoms show up across different areas of life (work or school, relationships, daily functioning).
- Rating scales & questionnaires
- Validated tools completed by you and, where relevant, by people who know you well — a partner, parent, or close colleague, or a teacher for children — to capture how symptoms present across different settings.
- Developmental history
- ADHD is a neurodevelopmental condition, so assessors look for evidence of symptoms going back to childhood, even if they weren’t recognised at the time.
- Other explanations
- Ruling out or identifying other conditions that can look similar to, or co-occur with, ADHD — such as anxiety, depression, or sleep difficulties.
- Cognitive or attention testing
- Some assessments include specific tests of attention and executive function, though practice varies between clinicians and isn’t always required for a diagnosis.
- Feedback session & report
- A session to discuss the outcome, followed by a written report outlining the findings and recommendations.
The full process is usually spread across more than one appointment rather than completed in a single session, particularly for adults where a thorough developmental history takes time to build.
Who it's for
Who is an ADHD assessment for?
Adults
Including those noticing long-standing patterns of disorganisation, procrastination, or difficulty with follow-through that they’re only now connecting to ADHD.
Children & adolescents
Showing attention, impulsivity, or hyperactivity difficulties affecting school or home life.
Second opinions & reassessment
Including those previously assessed as children who want an adult-specific evaluation.
Formal documentation
For workplace or study adjustments, or to access certain types of medication or support.
You don’t need to be certain you have ADHD to book an assessment — the process itself is designed to help figure that out.
Inclusions
What's included in an ADHD assessment?
While specifics vary by clinician, a typical comprehensive assessment includes the clinical interview(s), standardised questionnaires, a written report summarising findings against diagnostic criteria, and a feedback session to discuss the outcome and next steps. Check with your matched psychologist exactly what’s included in their specific assessment package before booking, as approaches and inclusions can differ between clinicians.
Cost
What does an ADHD assessment cost?
Costs for a comprehensive ADHD assessment in Australia vary depending on the clinician, the depth of the assessment, and whether cognitive testing is included. Assessments are a more involved and time-intensive process than a standard therapy session, which is generally reflected in the cost.
Medicare rebates for psychological assessment are limited and depend on your specific circumstances and referral pathway — a GP or psychiatrist can advise on what, if anything, may be claimable in your situation. Private health insurance extras cover may also contribute, depending on your policy. Because this varies significantly by individual circumstance and can change, we’d rather point you toward checking current Medicare and private health details directly than quote a figure here that may be out of date by the time you’re reading this.
Before you go
How to prepare for an ADHD assessment
- Gather background information
- School reports, old report cards, or anything documenting difficulties in childhood can be genuinely useful, though not essential.
- Think through examples
- Specific situations where attention, organisation, or impulsivity have caused real difficulty tend to be more useful to an assessor than general descriptions.
- Consider who else might contribute
- A partner, parent, or close friend who’s known you a long time can sometimes offer valuable perspective, especially for adult assessments.
- Bring any relevant history
- Previous mental health diagnoses, medications, or assessments, if applicable.

Common questions
Frequently asked questions
How long does an ADHD assessment take?
This varies by clinician, but a comprehensive assessment is usually spread across more than one session, particularly for adults, given the depth of developmental history involved. Ask your psychologist for their specific timeline when booking.
Can I get an ADHD assessment without a GP referral?
Yes — you can book directly with a psychologist for an ADHD assessment. A GP referral isn’t required to have the assessment itself, though it may be relevant to accessing certain Medicare rebates or if you’re also considering medication, which requires a GP or psychiatrist.
Does Medicare cover an ADHD assessment?
Medicare rebates for psychological assessment are limited and depend on individual circumstances and referral pathway. Speak with your GP about what may be available to you, and confirm current rebate details directly, as these can change.
Can a psychologist diagnose ADHD, or do I need a psychiatrist?
Psychologists can conduct comprehensive ADHD assessments and provide a diagnosis. If medication is being considered, a GP or psychiatrist will need to be involved, since psychologists cannot prescribe.
What happens after I get my results?
You’ll typically have a feedback session to discuss the outcome and receive a written report. If diagnosed, your psychologist can discuss support options, and if medication is relevant, can help you take the report to a GP or psychiatrist for that conversation.
What if the assessment finds I don’t have ADHD?
A thorough assessment aims to give you clarity either way, and often identifies other explanations for the difficulties you’re experiencing (such as anxiety, sleep issues, or another condition) so you can pursue the right support regardless of outcome.
