Attention-Deficit/Hyperactivity Disorder (ADHD) is a developmental disorder characterised by a persistent pattern of inattentive and/or hyperactive/impulsive behaviour that is more frequent and severe than is typically observed in individuals of the same developmental level. There are three types of ADHD:

What is ADHD?
How is an ADHD Assessment helpful?
An ADHD Assessment has the potential to:
Identify whether an individual has ADHD and therefore make better sense of their strengths and challenges
Determine what interventions/supports are likely to be helpful
Assist with accessing extra supports at school e.g. classroom accomodations and special exam provisions
Evaluate treatment progress
What is involved?
An ADHD Assessment typically involves five stages:
The first step involves meeting a clinician to discuss your concerns and what you would like to get out of testing. Your clinician will also gather a comprehensive history. The initial assessment is imperative in ensuring that the appropriate tests are administered, the findings are interpreted appropriately, and the recommendations are individually-tailored.
Duration: 1.5 hours
Your child is then administered either the Wechsler Preschool and Primary Scale of Intelligence – Fourth Edition (WPPSI-IV) (for children aged 2 years and 6 months to 7 years and 7 months) OR the Wechsler Intelligence Scales for Children – Fifth Edition (WISC-V) (for children aged 6 to 16 years).
Duration: 1 - 1.5 hours
Your child is then administered the Wechsler Individual Achievement Test – Second Edition (WIAT-III), which is appropriate for children aged 4 to 19 years and 11 months.
Duration: 1.5 - 2 hours
Your child is then administered either the Conners Kiddie Continuous Performance Test, 2nd Edition (for ages 4 to 7) OR Conners Continuous Performance Test, 3rd Edition (CPT-3) (for ages 8 years and older).
Duration: 15 - 20 minutes
You and your child's teacher(s) are then required to complete an online questionnaire, which looks at inattentive and hyperactive/impulsive behaviour, along with common co-occurring difficulties such as learning difficulties, behavioural difficulties, and peer problems.
Duration: 10 - 15 minutes (per questionnaire)
