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

ADHD Assessment

The process



An ADHD Assessment typically involves five stages: 

1

Initial Assessment

The first step involves meeting with a clinician to discuss the reason for referral 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

2

Cognitive Assessment

 

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: 1.5 hours

3

Academic Assessment

 

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: 2.5 hours

4

Attentional Assessment

 

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

5

Online Questionnaires

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)

6

Feedback Session

Once testing is complete, it typically takes 2-3 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.  

 

Duration: 1.5 hours
