Deciding to have your child assessed for ADHD can feel like a big step. Parents often tell us they've been wondering for years — watching their child struggle with focus, impulsivity, or organisation — before finally reaching out. If that sounds familiar, you're not alone, and getting clarity is genuinely worthwhile.
This guide walks you through exactly what a comprehensive ADHD assessment involves, what to expect at each stage, and how to make sense of the outcome.
What is ADHD, and why does assessment matter?
Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition affecting attention regulation, impulse control, and activity levels. It's one of the most common conditions seen in children and affects approximately 1 in 14 Australian children.
A formal assessment matters because ADHD presents differently in every child. Without a thorough evaluation, it's easy to miss — or to mistake other conditions (anxiety, learning difficulties, sleep issues) for ADHD, or vice versa. A proper assessment provides a clear picture, and that picture shapes everything that comes next: support at school, access to funding, medication decisions, and how you talk to your child about themselves.
Who conducts the assessment?
In Australia, ADHD can be assessed by a registered psychologist, paediatrician, or psychiatrist. Psychologists are typically best placed to conduct the full cognitive and behavioural assessment — particularly where learning difficulties, autism, or anxiety may also be present. A paediatrician or psychiatrist is required if medication is being considered.
At Three Bees Psychology, our ADHD assessments are conducted by AHPRA-registered psychologists using current best-practice frameworks and DSM-5-TR diagnostic criteria.
What does the assessment involve?
A comprehensive child ADHD assessment typically involves the following stages:
1. Initial consultation and history-taking
The process usually begins with a parent interview. This covers your child's developmental history, birth, early milestones, family history, and current concerns. It also covers school performance, social relationships, and daily functioning. This session typically lasts 60–90 minutes and may be done without your child present.
2. Teacher and parent rating scales
Standardised questionnaires are sent to both parents and teachers. These tools — such as the Conners, BRIEF, or SNAP — measure ADHD symptoms and behaviours across different settings. Because ADHD must be present in more than one environment to meet diagnostic criteria, this multi-informant approach is essential.
3. Direct assessment of your child
Your child will attend one or two sessions with the psychologist. These sessions typically include:
- A clinical interview with the child (age-appropriate)
- Cognitive testing to assess processing speed, working memory, and attention
- Continuous performance tasks (computerised attention measures)
- Observation of the child's behaviour during tasks
Most children find these sessions engaging rather than stressful — the tasks are designed to feel like activities rather than tests.
4. Report and feedback
The psychologist synthesises all information into a written report. The report will clearly state whether ADHD diagnostic criteria are met, which presentation type (inattentive, hyperactive-impulsive, or combined), and any co-occurring conditions identified. Crucially, it will include specific recommendations for home, school, and any other supports.
A feedback session with parents is usually included to walk through the findings and answer questions.
How long does the whole process take?
From initial contact to receiving the final report, most families should allow 4–8 weeks. This accounts for scheduling, completing rating scales, and report writing time. Urgent assessments can sometimes be accommodated — speak to us at enquiry stage if timing is a concern.
What happens after the assessment?
A diagnosis (or clear findings) opens several doors:
- School support: The report can be used to apply for a Student Support Group, adjustments, or additional resources
- Medication: If medication is recommended, your GP or paediatrician can use the report to guide prescribing
- NDIS: Some children with ADHD may be eligible for NDIS funding depending on their level of functional impairment
- Therapy: Strategies for attention, emotional regulation, and executive function can be put in place through psychology sessions
A note on diagnosis
Not every assessment results in an ADHD diagnosis — and that's also a useful outcome. Understanding what is and isn't happening for your child is the goal. Sometimes the assessment reveals anxiety, a learning difficulty, or giftedness that has been masking itself as inattention. Whatever the outcome, you leave with a clearer picture and a path forward.
