Can a Psychologist Diagnose ADHD? What They Can and Can’t Do

Short answer: Yes. In Australia, a psychologist who is trained and experienced in ADHD assessment can diagnose ADHD.¹ But a psychologist isn’t a medical doctor and can’t prescribe medicines.² So if you’d like medication to be considered, you’ll also need to see a doctor who can prescribe it, and before starting medication that doctor needs to confirm the diagnostic criteria are met.¹ It’s worth knowing this before you book an assessment.

Can a psychologist diagnose ADHD?

Yes. The Australian ADHD Guideline doesn’t limit diagnosis to one profession. It says clinicians who diagnose ADHD should be appropriately registered (for example, with Ahpra), trained in diagnostic assessment using the recognised diagnostic manuals, experienced with clinical interviews and standardised rating scales, and experienced in ADHD assessment or receiving ADHD-specific supervision.¹

That means a suitably trained psychologist, psychiatrist or paediatrician can assess ADHD. In Queensland, a doctor who can’t diagnose ADHD may refer you to a paediatrician, psychiatrist or psychologist,³ and since December 2025 Queensland GPs can also diagnose and treat ADHD in adults.⁴ The rules for doctors differ between states and territories. See can a GP diagnose ADHD in Australia?

Can a psychologist prescribe ADHD medication?

No. A psychologist is not a medical doctor and can’t prescribe medicines. A psychiatrist has trained as a medical doctor and can.²

Stimulant medicines for ADHD are Schedule 8 medicines, which have special rules to reduce the risk of misuse or dependence.⁵ In Queensland, GPs with specialist registration in general practice can start, adjust and continue these medicines for adults with ADHD.⁶ Each state and territory sets its own rules about which doctors can start them.

Already diagnosed by a psychologist?

A psychologist’s diagnosis is a real diagnosis, and their report is worth keeping. But if you want to try medication, it won’t get you a prescription on its own.

Before anyone starts ADHD medication, the Australian ADHD Guideline says the assessment must include confirmation that the ADHD diagnostic criteria are met.¹ In practice, the doctor who prescribes will make their own assessment, using the psychologist’s report as part of the picture. If you go ahead with medication, your heart rate, blood pressure, weight, sleep, mood and anxiety are monitored as the dose is adjusted.¹

In some states, a psychologist’s diagnosis also isn’t enough for a GP to prescribe. In Victoria, for example, a GP is generally only issued a permit to prescribe stimulants where there is evidence of a specialist diagnosis and a recent specialist review.⁷

When you see a doctor, bring:

• your psychologist’s report
• school reports or other records from childhood, if you have them
• a list of the medicines and supplements you take
• notes on how your symptoms affect work, study, relationships and daily life

Medication or therapy: what the evidence says

The Australian ADHD Guideline is clear about the roles of each. It says medication is the most effective treatment for reducing the core symptoms of ADHD, and that non-medication treatments provide additional support to reduce the day-to-day impact of those symptoms.¹

That doesn’t make therapy pointless. It does a different job. The guideline recommends that cognitive-behavioural interventions be offered to adults with ADHD. It makes this a strong recommendation, although it rates the certainty of the evidence as low.¹ Cognitive behavioural therapy (CBT) can help you develop strategies and skills for managing your behaviour,⁸ and your doctor may suggest combining psychological approaches with medicine.⁸

The guideline also says the treatment plan should fit the person’s preferences, needs and goals.¹ Some people prefer to start with non-medication approaches, some can’t take medication, and many use both. For options that don’t involve medicine, see how to manage ADHD without medication.

What psychologists do well

Psychologists are registered health professionals trained in human behaviour, and their main focus is psychotherapy (talk therapy) to help people manage their mental health.² For someone with ADHD, that can include:

• Assessment: a thorough ADHD assessment by a psychologist with the right training and experience¹
• Skills-based therapy: CBT to build practical strategies for organisation, planning and managing everyday challenges⁸
• Help with other conditions: psychological therapy, including CBT, is a main treatment for anxiety,⁹ which often occurs alongside ADHD. See ADHD and anxiety.

Medicare covers some of the cost of seeing a psychologist if you have a referral or a mental health treatment plan from your doctor.² Under the Better Access initiative, Medicare benefits are available for up to 10 individual sessions each calendar year for people who are eligible, and your GP decides whether you are.¹⁰

Where to start

• If you’re not sure whether it’s ADHD, start with your GP. They can talk through your symptoms, check for other causes and explain your options.
• If you’d like medication to be considered, see a doctor who can prescribe under your state’s rules. In Queensland, that can be a GP.⁴
• If you mainly want help with strategies or with anxiety or low mood, a psychologist with ADHD experience is a good fit, and your GP can arrange a referral.

Before booking any assessment, it’s fair to ask: “If I’m diagnosed, can you prescribe, and if not, what happens next?” The answer helps you avoid paying for steps you’ll need to repeat.

If you’re struggling in the meantime, you can call Lifeline on 13 11 14 or Beyond Blue on 1300 22 4636, 24 hours a day. In an emergency, call 000.¹¹

Frequently asked questions

Can a psychologist diagnose ADHD?

Yes. In Australia, a psychologist who is trained and experienced in ADHD assessment can assess and diagnose ADHD.

Can a psychologist prescribe ADHD medication?

No. Psychologists aren’t medical doctors and can’t prescribe medicines. ADHD medicines are prescribed by doctors such as psychiatrists, and in Queensland GPs can prescribe them for adults too.

If a psychologist diagnoses me, can I get ADHD medication?

You’ll need to see a doctor who can prescribe under your state’s rules. Before starting medication, the doctor needs to confirm that the diagnostic criteria are met, so they’ll make their own assessment, and the psychologist’s report can be part of it.

Is medication or therapy better for ADHD?

The Australian ADHD Guideline says medication is the most effective treatment for reducing the core symptoms of ADHD, and that non-medication treatments such as cognitive behavioural therapy provide additional support with the day-to-day impact. Many people use both.

Does Medicare cover seeing a psychologist?

Medicare covers some of the cost of seeing a psychologist if you have a referral or mental health treatment plan from your doctor. Under the Better Access initiative, rebates are available for up to 10 individual sessions a calendar year for people who are eligible.
