What is ADHD
How can ADHD testing help
Evaluating whether a child meets criteria for ADHD
Gaining greater insight into a child's strengths and weaknesses and therefore how to best support them
Ruling out overlapping issues such as working memory weakness, processing speed weakness, learning difficulties, and anxiety
Accessing supports at school including classroom adjustments/accomodations and special exam provisions
Evaluating treatment progress
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)
Once testing is complete, it typically takes 3 weeks for your clinician to score and prepare your report. Your clinician will then meet with you to discuss the results and recommendations. Your report will contain a detailed overview of the results and individually-tailored recommendations.
