Who can diagnose ADHD in Australia?

If you are trying to work out who can diagnose ADHD in Australia, you may have found conflicting advice. One source says to see a paediatrician, another recommends a psychiatrist or psychologist, and another says a GP may now be able to help.

The national principle is that ADHD should be diagnosed by an appropriately registered health professional who has the training, experience and competence to conduct a comprehensive assessment within their scope of practice.¹ In Australia, paediatricians, psychiatrists and appropriately trained psychologists commonly diagnose ADHD. Some appropriately trained GPs and nurse practitioners may also have a diagnostic role, but their services and responsibilities vary.

This guide focuses mainly on choosing professionals for children and adolescents. Many of the broad distinctions also apply to adults, although adult services and pathways can differ. It is also important to separate four questions: who can diagnose, who can prescribe, whether Medicare may apply, and whether another organisation will accept a report.

How to understand who can diagnose ADHD

The clearest way to compare professionals is to look at the individual clinician's competence, the assessment they provide and what your family needs afterwards.

For a fuller explanation of the assessment process, see ADHD Assessment in Australia: A Guide for Parents.

Professional competence matters more than job title

Doctors, psychologists and other registered health professionals are expected to recognise the limits of their competence and practise within their individual scope.^4,5 In practical terms, a paediatrician may focus on another area of child health, a psychiatrist may not assess children, and a psychologist may specialise in concerns other than ADHD.

Competence develops through education, relevant training, supervised and ongoing practice, professional development and experience with the people being assessed. This is why the question, "Does this clinician regularly conduct comprehensive ADHD assessments for children like mine?" is usually more useful than relying on a job title alone.

Why ADHD assessment requires specific experience

ADHD assessment is not the completion of one questionnaire or computer task. The clinician considers the child's history, current functioning and the context in which concerns occur. They also consider whether another condition or circumstance may explain some difficulties, or whether more than one need may be present.¹

Questionnaires can organise observations from parents, educators or the young person. Interviews help explain history and context. Previous educational, developmental or health reports may add useful information. A medical assessment and clinical observations may also be relevant.

The 2024 Peterson systematic review found substantial variation in the performance of individual diagnostic tools. It supports experienced clinical judgement informed by structured information and more than one perspective, rather than reliance on one tool.³

This is Threadline's Building the Fuller Picture principle: different sources contribute information, while the assessing clinician remains responsible for interpretation and any diagnosis.

Why different professionals may contribute

One clinician may lead the assessment, but information can come from several people. Parents and carers describe development and everyday life. A child or young person can explain their own experience. Teachers and school staff may describe learning, organisation and relationships in another setting. Health and allied-health professionals may contribute assessments relevant to their own disciplines.^1,2

Collaborative assessment does not mean every child needs a large team. The professionals involved should reflect the questions that need to be answered. One clinician remains responsible for bringing the available information together and deciding whether more is needed.

Which professionals diagnose ADHD?

Paediatricians, psychiatrists and appropriately trained psychologists commonly diagnose ADHD in Australia. Appropriately trained GPs and some nurse practitioners may also diagnose within their competence and the arrangements that apply to their service.^1,4,5,6

The right starting point depends on your child's age, the concerns being explored, other health or developmental needs, local availability and the purpose of the assessment.

Paediatricians

Paediatricians are doctors who specialise in the health and development of infants, children and adolescents. They commonly assess ADHD in children, particularly where concerns overlap with development, learning, sleep, growth, physical health or other childhood conditions.

A paediatrician may gather information from the family, child, school and previous clinicians, consider the child's overall health and decide whether ADHD or another explanation best accounts for the difficulties. Their medical training can be useful when developmental and medical questions need to be considered together.

If ADHD is diagnosed, a paediatrician may explain the findings, discuss treatment and support options, and provide follow-up. In other cases, ongoing care may be shared with a GP, psychologist, school or other professionals.

Not every paediatrician offers ADHD assessment or sees every age group. Families should confirm the clinician's ADHD experience, age limits, reporting arrangements and follow-up before booking.

Paediatricians may prescribe within their competence and applicable arrangements. Their ability to prescribe does not make prescribing and diagnosis the same task.⁴

Child and adolescent psychiatrists

Child and adolescent psychiatrists are specialist doctors who focus on the mental health of children and young people.

They commonly assess ADHD and may be particularly helpful where there are significant emotional or behavioural concerns, diagnostic uncertainty, risk, substance use or other mental health conditions that need specialist consideration.

Their assessment still involves building the fuller picture. A psychiatrist may explore development, mental health, family and social context, functioning, previous support and information from school or other clinicians. They may also conduct a medical and mental-state assessment.

Seeing a psychiatrist does not mean a child's difficulties are necessarily more serious, and a child does not automatically need psychiatric assessment because ADHD is being considered. The choice depends on the clinical questions and the child's circumstances.

Some psychiatrists spend a large part of their practice assessing ADHD, while others focus on different conditions or age groups. Ask whether the psychiatrist works with children of your child's age and whether ongoing care is offered after assessment.

Can a psychologist diagnose ADHD in Australia?

Yes. An appropriately trained psychologist may assess and diagnose ADHD when the work is within their professional competence and scope.⁵

Psychologists specialise in understanding behaviour, learning, thinking and emotional wellbeing. Many assess ADHD as part of broader psychological or neurodevelopmental practice. Their assessment may include interviews, developmental and functional history, school information, previous reports and structured tools where appropriate.

Some psychologists also assess learning, cognitive functioning, language-related concerns or emotional wellbeing when those questions are relevant. Additional testing should have a clear purpose and is not required for every ADHD diagnosis.

A psychologist may reach a diagnosis, explain the findings and recommend supports or further care. Psychologists do not prescribe ADHD medication. If medication is later considered, a medical practitioner or another authorised prescriber may need to become involved.

Not every psychologist regularly assesses ADHD. General registration and an area-of-practice endorsement do not automatically establish ADHD-specific experience. Ask what the psychologist's assessment includes, how medical input is handled and whether the report is likely to suit your family's intended next step.

Can a GP diagnose ADHD in Australia?

Some appropriately trained GPs may diagnose ADHD, but there is no single national pathway that means every GP offers the same service.^4,7

A GP is often the first health professional a family speaks with. They may already know the child and family, understand their health history and help decide what should happen next.

GPs commonly recognise concerns, check for other health issues, arrange referrals, coordinate care and provide monitoring or shared care. Recognising that a child may need assessment is important, but it is not the same as completing a comprehensive diagnostic assessment.

Some GPs conduct ADHD assessments and diagnose within their competence. In parts of Australia, trained-GP pathways have expanded or are expanding the GP role in assessment, diagnosis, prescribing or shared care. These arrangements differ and should not be generalised nationally.⁷

A GP may be involved in one or more of the following:

• recognising concerns that warrant assessment
• contributing medical and developmental information
• conducting or participating in an assessment where appropriately trained
• making a diagnosis within their competence and service arrangements
• prescribing where authorised
• monitoring care or sharing responsibility with another clinician

These roles do not always occur together. A GP may manage ongoing care without making the original diagnosis. Another may assess and diagnose but involve a paediatrician or psychiatrist for complexity or treatment.

Nurse practitioners

Some nurse practitioners may have a role in ADHD assessment, diagnosis, treatment or monitoring within their endorsed scope and local service arrangements.⁶

Nurse practitioners are registered nurses with advanced education and clinical experience. They may assess, diagnose and implement treatment within scope, and may prescribe subject to applicable law and service arrangements.

Their ADHD role is evolving and is not a routine national pathway. Ask what the particular nurse practitioner provides, which age groups they see and how their role connects with other clinicians.

Other health professionals involved in ADHD assessment

Occupational therapists, speech pathologists, social workers, counsellors and other allied-health professionals may contribute valuable assessments and observations. Teachers and other school staff can provide information about learning, organisation, participation and relationships in another important setting.^1,2

An occupational therapist might describe daily activities, sensory demands, motor tasks or participation. A speech pathologist may assess language, communication or social interaction. A social worker or counsellor may contribute information about wellbeing, relationships and family or social circumstances.

Their reports can help the clinician understand a child's strengths and challenges, but an occupational therapy report, speech pathology assessment, teacher questionnaire or school observation does not independently establish ADHD on its own.

A professional could only make a diagnosis where they separately hold the relevant registration, competence and scope. Titles such as counsellor, coach or psychotherapist do not by themselves establish a nationally regulated diagnostic role.

Is diagnosing ADHD the same as prescribing medication?

No. Diagnosis and prescribing are separate professional responsibilities, although one clinician may sometimes do both.^1,4,5,6

Diagnosis is the clinical conclusion reached after a comprehensive assessment. Prescribing involves deciding whether medication is appropriate, discussing possible benefits and risks, choosing a medicine if needed and arranging monitoring. Prescribing authority is governed by different professional and legal frameworks.

A paediatrician or psychiatrist may assess, diagnose and continue to manage treatment. In another pathway, a psychologist may diagnose and a medical practitioner later considers medication. A GP may also manage ongoing treatment after another clinician led the assessment.

Medication is only one possible part of ADHD care. Assessment may lead to discussion of school adjustments, psychological support, practical strategies, family support or treatment of other needs. A diagnosis does not automatically lead to medication.

For more detail about the diagnostic decision, see How to Get an ADHD Diagnosis in Australia.

Do you need a referral, and does Medicare apply?

Sometimes. Referral requirements and Medicare eligibility depend on the clinician, service and funding pathway, not simply on who is competent to diagnose ADHD.⁸

Some private psychologists and assessment services accept direct enquiries. Other services require an ADHD referral or apply their own eligibility rules. A valid referral is generally required for Medicare benefits for private specialist and consultant physician appointments, including paediatrician and psychiatrist appointments.⁸

A GP can still be a useful starting point when direct booking is available. They may discuss concerns, review health history, identify suitable services and explain which referral arrangements may apply.

Medicare eligibility depends on government funding rules, the provider, the service delivered and the relevant referral or plan. A clinician may be competent to diagnose ADHD even when their service does not attract a Medicare benefit. Receiving a rebate also does not establish that a clinician has extensive ADHD experience.

Psychology rebates depend on the service and the applicable Medicare pathway. There is no universal rule that a private psychology ADHD assessment will be covered. Paediatricians and psychiatrists may also charge more than the Medicare schedule fee, leaving an out-of-pocket cost.

Before booking, ask what the total fee includes, whether a referral is needed, whether any Medicare benefit may apply and whether reports or follow-up cost extra.

How do you choose the right clinician?

Choose a clinician by matching their ADHD experience and service to your child's needs, rather than searching for one profession that is right for every family.

A paediatrician may offer combined developmental and medical expertise. A child and adolescent psychiatrist may be helpful where mental health complexity is central. A psychologist may provide detailed psychological, functional or learning-related assessment. A GP may be the starting point, coordinator or, in some services, the assessing clinician.

Consider what you need the assessment to answer. Are there broad developmental or medical concerns? Are significant mental health needs or several possible conditions central to the referral? Is detailed information about learning or psychological functioning needed? Will the family need a separate medical or prescribing pathway afterwards?

The service should be able to explain what it provides, who makes the diagnostic decision, how other professional input is arranged and what happens after the assessment.

You do not need to become an expert in professional regulation. You need enough information to understand the pathway, its limits and whether it is likely to meet your child's needs.

Families considering remote services may also find the planned guide, Online and Telehealth ADHD Assessment in Australia, useful when it is published.

Questions to ask before booking an ADHD assessment

Ask practical questions that reveal what the clinician and service actually provide.

• Does this clinician regularly assess ADHD in children of my child's age?
• What does the assessment include, and who makes the final diagnostic decision?
• Is a medical assessment included or arranged separately?
• If medication is later considered, who would manage that part of care?
• Is a referral needed, and might Medicare apply?
• What is included in the total fee?
• Will we receive a report or written summary?
• Will the report meet the requirements of the service or organisation that may use it?
• What follow-up is offered, and who is responsible for each next step?

The planned Questions to Ask Before Booking an ADHD Assessment resource will bring these questions together in a practical format for speaking with a GP, contacting a clinic or comparing pathways.
