How to Get an ADHD Diagnosis in Australia

A practical pathway for parents seeking an ADHD assessment and diagnostic decision for a child or adolescent.

If you are wondering how to get an ADHD diagnosis for your child in Australia, a GP is a common place to start, but it is not the only possible entry point. You can also contact an appropriate assessment service and ask how access works. Before booking, check the service’s age range, referral and Medicare requirements, who conducts the assessment and what information it requests.

ADHD is not diagnosed by one questionnaire, appointment, computer task or “ADHD test”. Diagnosis follows a comprehensive clinical assessment in which an appropriately trained and experienced clinician reviews the available evidence and makes the decision.^1,2,10

This guide focuses on children and adolescents. Adult pathways can differ.

How the ADHD diagnosis pathway works

Many families move through the following decisions, although stages can overlap, occur in a different order or involve more than one professional:

1. Notice concerns
2. Decide where to start
3. Check the clinician, access and service requirements
4. Gather useful information
5. Take part in a comprehensive assessment
6. Provide more information or obtain another assessment where clinically required
7. Receive the clinician’s decision and explanation
8. Plan the next steps

Step 1 – Notice concerns

It is reasonable to seek advice when difficulties with attention, activity, impulsivity, organisation or related areas are affecting your child’s learning, relationships, wellbeing or everyday life. Concerns may be raised by you, your child or teenager, a teacher, a GP or another professional.^4,5

You do not need to be certain that ADHD is the explanation. Similar difficulties can occur for many reasons. Concerns are a reason to ask questions, not a diagnosis.

Step 2 – Decide where to start

A GP is a common starting point. They can discuss the concerns, consider immediate health or support needs, explain local options and make a referral where required. Starting with a GP does not mean that every GP personally offers ADHD assessment or diagnosis.

You can also contact an appropriate private or public service and ask how access works. Before assuming that a service is suitable, check its age range, eligibility rules, referral requirements and what it actually provides.

When you speak with your child or teenager about seeking assessment, explain that the purpose is to understand their experiences and support needs. Avoid presenting the appointment as a test they must pass or as a process that is certain to produce an ADHD diagnosis.

Step 3 – Check the clinician, access and service requirements

Choose a clinician or service with relevant ADHD assessment training and experience. A professional title alone does not show how much ADHD-specific work a practitioner does. Australian guidance recommends that diagnostic assessments be conducted by an appropriately registered clinician who is trained and experienced in ADHD assessment, or is receiving appropriate ADHD-specific supervision.^1,6

Before booking, ask:

• whether the service assesses children in your child’s age group
• who completes each part of the assessment
• who makes the diagnostic decision
• how developmental, learning, mental-health and medical information are considered
• whether relevant medical assessment is included or coordinated elsewhere
• what feedback or written information is provided
• what happens if more information or another professional is needed.

The useful answer is not necessarily that one clinician does everything. It is that responsibilities and next steps are clear.

Referrals and Medicare are separate questions

A service’s booking rules and Medicare eligibility are not the same thing. For Medicare benefits for specialist or consultant physician treatment, a valid referral is generally required. A GP referral generally lasts 12 months from the specialist’s first meeting with the patient unless the referral states a different period.⁷

A mental health treatment plan can support access to eligible mental health treatment services, but it should not be treated as one universal Medicare benefit for every component of a comprehensive ADHD diagnostic assessment. Ask the service which appointments may attract a benefit and what referral or plan is required.⁸

Private services and public pathways can have different age, eligibility, fee, referral and reporting arrangements. When asking about a public option, confirm whether the service currently assesses ADHD, which children it accepts, who can refer and what happens if a referral is declined. When comparing private services, ask for the total likely cost and whether additional appointments or reports are charged separately.

Step 4 – Gather useful information

You do not need to assemble a case that proves your child has ADHD. Preparation helps the clinician understand what is happening, how it affects daily life and what may need closer assessment.

Depending on your child and the service, useful information may include:

• examples of concerns, functional impact, strengths and strategies that help
• developmental, physical-health and mental-health history
• sleep, medications and relevant family history
• school reports, support plans and previous assessments
• information from parents, carers and other people who know the child well
• your child or teenager’s own perspective
• questionnaires selected by the clinician or service.^1,2,3

Not every family has the same records. Bring what is relevant and reasonably available, and tell the clinician what is missing or uncertain.

Why information from more than one setting matters

ADHD assessment considers how difficulties and functioning appear across important settings, such as home, school and community activities. Reports can differ because demands, expectations and supports differ. The clinician interprets those differences rather than treating the assessment as a vote between parent, teacher and young person.

School information is commonly useful because school is a major setting in a child’s life. However, no particular teacher questionnaire is universally mandatory. If a form, school report or teacher account cannot be obtained, ask the clinician what other evidence may be useful.^1,2

What questionnaires can and cannot do

Rating scales can organise observations, compare perspectives and identify topics for discussion. They do not establish the diagnosis by themselves. Research on diagnostic tools also shows that the performance of individual tools varies, especially when children with ADHD are compared with other clinically referred children.^1,10

Step 5 – Take part in a comprehensive assessment

A comprehensive ADHD assessment usually brings together interviews, history, information about functioning, observations or reports from relevant settings, and any additional assessment that is clinically indicated. It may occur over one appointment or several.

The clinician may speak with parents or carers and the child or adolescent together, separately or in a combination that suits the child’s age and circumstances. The young person’s account can add information about effort, distress, coping strategies, strengths and experiences that adults may not readily observe.

The clinician may consider:

• the current concerns and their effect on everyday life
• development and experiences over time
• physical health, mental health, sleep and medications
• learning, language and social development
• strengths, supports and the child’s perspective
• information from relevant settings
• possible alternative explanations and co-occurring needs.^1,2,3

What is the role of medical assessment?

Medical history and assessment can help identify health factors that may contribute to the difficulties, associated conditions that need attention and issues relevant to treatment planning. Medical investigations should be guided by clinical indications rather than used as universal ADHD tests.

Not every component must be completed by the same clinician. A service may coordinate medical input with another practitioner. Ask who is responsible for this part and whether an in-person examination may be needed.

Some interviews and information gathering may be suitable for telehealth, but the practitioner must decide that remote care is safe, clinically appropriate and suitable for the child. Face-to-face examination or observation may still be required.⁹

Is there a definitive ADHD test?

No. A blood test, brain scan, EEG, computer task, neuropsychological test or questionnaire cannot independently establish ADHD. Some tests can be useful when a clinician is investigating a particular medical, learning or developmental question, but they do not replace comprehensive clinical assessment.^1,2,10

How are other possible explanations considered?

Difficulties with attention, activity, organisation, learning or emotions can be influenced by developmental, learning, medical, environmental and mental-health factors. Some can coexist with ADHD. The clinician evaluates the overall pattern and may recommend targeted assessment or another professional opinion.

This is not a mechanical process of “ruling conditions in or out” with one questionnaire.

Step 6 – Provide more information or obtain another assessment if needed

The clinician may decide that more information is needed before reaching a clear conclusion. This can happen when accounts differ, early history is limited, school information is unavailable, health questions require review, or another developmental, learning or mental-health issue needs closer assessment.

Further steps might include:

• another conversation with the family or young person
• earlier records or information from another setting
• medical review
• hearing, vision, learning, language or other targeted assessment
• input from another appropriately qualified professional.

A request for more information does not mean that the family prepared badly or that ADHD will eventually be diagnosed. The clinician decides what is relevant and whether the available evidence is sufficient.

Practical support does not always need to wait for a final diagnostic decision. Families can ask which strategies, school discussions, health reviews or other supports are reasonable while assessment continues, recognising that access to particular treatments, funding or services may have separate eligibility requirements.

Step 7 – Receive the clinician’s decision and explanation

An appropriately trained and experienced clinician integrates the available evidence and makes the diagnostic decision. The decision should not be based on one score, one person’s account or the number of documents a family provides.^1,2

Feedback should explain:

• the conclusion reached
• the information considered
• the child’s strengths and identified needs
• any uncertainty or further assessment recommended
• practical next steps and follow-up.

Diagnosis and prescribing are different decisions

A clinician may diagnose ADHD without providing medication assessment or prescribing. Treatment responsibility, prescribing authority and jurisdictional requirements are separate questions. See Who Can Diagnose ADHD in Australia?

Also ask what written information or report will be provided. A report is not automatically accepted for every later school, funding, treatment or prescribing purpose.

Possible outcomes

The assessment does not automatically end in an ADHD diagnosis.

These are clinical outcomes, not pass-or-fail results. Not receiving an ADHD diagnosis does not mean that the concerns or their effect on everyday life are unimportant.

Step 8 – Plan the next steps

The next plan should respond to what the assessment identified. Depending on the outcome, this may include information, practical changes at home or school, support planning, psychological or behavioural approaches, medical review, further assessment or a discussion about medication.³

An ADHD diagnosis does not make medication automatic. Treatment decisions should consider the child’s needs, health and preferences, as well as the responsibilities and authority of the clinicians involved.

Ask:

• what can begin now
• who is responsible for each action
• whether another referral is needed
• what follow-up is included
• when progress or remaining concerns should be reviewed.

Questions to ask before booking

Use this checklist when comparing services:

• Do you assess children in my child’s age group?
• What ADHD-specific training and experience does the clinician have?
• Who completes each part, and who makes the diagnostic decision?
• Do we need a referral to book or to claim any Medicare benefit?
• What interviews, questionnaires and other assessment components are included?
• What information will you request from the family, child and school?
• What happens if school information or earlier records are unavailable?
• How are developmental, mental-health and medical considerations addressed?
• What feedback or written report is provided?
• Will the report usually suit the purpose for which we need it?
• What are the total fees, possible benefits, waiting time and cancellation terms?
• What happens if more information or another assessment is recommended?
