Thorough ADHD assessment in Sydney.
Finished in weeks, not months.
Comprehensive ADHD diagnostic assessment for children, teens and adults. We use the WISC-V, Conners 4, clinical interviews and behavioural observation to deliver a clear written report within 7 working days. No referral required. No waitlist.
ADHD assessment that goes beyond a checklist.
ADHD is more than a focus problem. It affects how a person manages attention, energy, emotion, motivation, time, and self-regulation. The way it shows up can look very different across school, home, work, and leisure. A good assessment captures that complexity.
At Spectrum Assessments, an ADHD diagnostic workup is built around four pillars. First, cognitive testing using the WISC-V (or WAIS-5 for adults) to map strengths and challenges. Second, the Conners 4 questionnaires completed by parents, teachers, and the young person themselves. Third, a clinical interview to understand history and current functioning. And fourth, behavioural observation by an experienced clinician.
We see clients across Sydney's North Shore in person at our St Leonards rooms. Many ADHD assessments can also be completed via secure telehealth for clients across Australia.
Who this is for
Common signs an ADHD assessment may help.
Difficulty starting tasks. Even tasks that matter and feel important.
Easily distracted by sounds, thoughts, or other tasks. Especially in unstructured environments.
Hyperfocus and getting absorbed in one thing at the expense of everything else.
Forgetting things: appointments, instructions, where you put your keys, why you walked into the room.
Restlessness, fidgeting, or feeling driven by a motor.
Emotional regulation that runs hot. Quick to frustrate, quick to recover.
Time blindness. Chronic lateness, underestimating how long things take.
Trouble with organisation, planning, and finishing what you start.
Years of feeling capable but underperforming relative to that capability.
What the assessment involves.
An ADHD (Attention-Deficit/Hyperactivity Disorder) assessment explores how a person thinks, focuses, and regulates attention, energy, and emotions. ADHD can affect learning, relationships, and daily functioning, and may present as inattentiveness, hyperactivity, impulsivity, or a mix of these.
Our assessment includes a WISC-V cognitive assessment to evaluate strengths and weaknesses in learning and thinking, Conners 4 and other standardised questionnaires completed by parents, teachers, and the young person themselves, plus clinical interviews to gather background information and observe behaviour.
Why assessment helps
A thorough ADHD assessment helps differentiate ADHD from other learning or emotional factors, and provides a roadmap for classroom support, home strategies, and (where relevant) medical management. Understanding your child’s profile allows teachers and families to work together to support attention, motivation, and confidence, so your child feels understood, not broken.
What the ADHD assessment process looks like.
-
01
Initial enquiry & consultation
Reach out. We will discuss what you are noticing, what an ADHD assessment involves, and what it costs before you commit. No referral required.
-
02
Background & history
We collect detailed background information including developmental history, school reports, prior assessments, and current functioning. For children, school questionnaires are sent at this stage.
-
03
Cognitive testing
WISC-V for children and teens, WAIS-5 for adults. Cognitive testing maps strengths and weaknesses across reasoning, working memory, processing speed, and verbal and visual skills. It often reveals patterns that explain a lot.
-
04
Conners 4 & clinical interview
Standardised ADHD rating scales (Conners 4) completed by parents, teachers and the young person, plus a structured clinical interview. For adults, we use age-appropriate self-report and informant scales.
-
05
Analysis & report
We integrate cognitive results, questionnaires, history and observations into a comprehensive written report including the diagnostic outcome, profile, and tailored recommendations. Typically delivered within 7 working days of your final session.
-
06
Feedback session
We meet again to walk through the report. School strategies, home strategies, medication discussions if relevant, and a clear pathway forward.
What you receive.
Comprehensive diagnostic report
A written report covering the diagnostic outcome, cognitive profile, and tailored, plain-language recommendations.
Feedback session
Walk through the report together. Time to ask questions and discuss next steps.
