If you are wondering, “Who can diagnose ADHD in my child?”, you've come to the right place. Parents concerned about their child's behaviour and attention span often consider seeking a professional diagnosis to determine whether there is an underlying cause.
This guide explains who is qualified to diagnose ADHD, what ADHD can look like in a child, and what a thorough assessment involves from start to finish. Our goal is to give you a clear, practical understanding of what to expect so that you can take the next step with confidence.
Common Signs of ADHD in a Child
ADHD stands for Attention Deficit Hyperactivity Disorder. It is a neurodevelopmental condition that affects a child's attention, impulse control, and ability to manage everyday tasks. ADHD does not reflect a lack of effort or poor parenting. It relates to differences in how the brain develops and functions.
ADHD is typically observed in three presentations:
Predominantly Inattentive: Difficulty sustaining focus, frequent distractibility, losing items, and forgetting instructions.
Predominantly Hyperactive-Impulsive: Restlessness, difficulty remaining seated, talking excessively, and acting before thinking
Combined Presentation: Features of both inattention and hyperactivity-impulsivity
Children with ADHD experience the condition in their own way. Some are more inattentive, while others are more hyperactive or impulsive. Many show a mix of both. Because signs vary, a careful, structured ADHD assessment is the optimal way to reach a diagnosis.
Who Can Diagnose ADHD in a Child?
In Australia, ADHD in children is usually diagnosed through a comprehensive assessment by trained health professionals. This often involves a general practitioner, paediatrician, child psychiatrist, and psychologist, with information gathered from parents, teachers, school reports, and clinical testing with the child.
Depending on the child's needs, an assessment for ADHD may involve:
Clinical and Registered psychologists: These professionals conduct comprehensive behavioural, academic, and cognitive assessments, gathering information from parents and teachers to provide a formal diagnosis and recommend targeted support.
Paediatricians: These are specialist doctors for children who can diagnose ADHD and prescribe medication where appropriate.
Psychiatrists: These are medical doctors specialising in mental health and can diagnose ADHD and manage medication.
How a Registered or Clinical Psychologist Assesses ADHD in a Child
Reliably diagnosing ADHD takes more than a single appointment or a quick online quiz. Diagnosis is a structured process in which the assessing psychologist gathers comprehensive information from several sources. A thorough assessment usually includes the following steps:
Step 1: Intake Call
The process begins with an intake call. This first conversation helps determine whether a full assessment for ADHD, a learning assessment, or both is most appropriate for a child. It is also an opportunity to ask questions and understand what the assessment process will involve before committing.
Step 2: Online Clinical Interview with Parents
Next, the psychologist meets with parents for a one-on-one interview. This session gathers detailed information about the child's developmental history, behaviour, academic concerns, medical background, interests, and overall wellbeing. Any existing medical, psychological, or school reports are also reviewed during this stage
Step 3: Child Testing and Assessment
The child then completes a few structured testing sessions. These cover:
Cognitive ability, including verbal comprehension, fluid reasoning, visual spatial reasoning, working memory, and processing speed
Executive functioning, such as impulse control, planning, and cognitive flexibility
Academic skills, including reading, writing, and mathematics
Social and emotional functioning, through questionnaires that look at behaviour across different settings
Teachers and parents may also complete online screening tools. These provide insight into focus and attention-related behaviours across different environments, thereby strengthening the assessment's accuracy.
Step 4: Analysis and Written Report
The psychologist analyses all findings, observations, and background information together, looking for patterns consistent with ADHD. The psychologist also checks for a Specific Learning Disorder such as dyslexia (reading), dysgraphia (writing), or dyscalculia (maths), which often occur alongside ADHD.
The psychologist then prepares a detailed written report. It explains the findings clearly and includes practical recommendations, such as learning supports, therapy options, classroom accommodations, and lifestyle adjustments. The report is designed to be useful for parents, teachers, and schools.
Step 5: Online Feedback Session With Parents
Finally, the psychologist meets with parents online to explain the results clearly and sensitively. This session addresses parents’ questions and outlines the next steps. An electronic copy of the report may also be emailed to the parents after the session.
