Comprehensive ADHD Testing for All Ages
Psychologists in our network provide in-depth ADHD assessments for both children and adults in Ottawa and Gatineau, helping clients better understand attention-related difficulties and access appropriate support. Whether you’re a parent seeking clarity for your child, or an adult who suspects ADHD may be affecting your work or daily life, a formal evaluation can be a critical step toward improved functioning and well-being.
What Is ADHD?
Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition characterized by patterns of inattention, hyperactivity, and/or impulsivity that interfere with daily functioning. While commonly diagnosed in childhood, many individuals go undiagnosed until adulthood. A formal psychological assessment is the most reliable way to determine whether symptoms meet diagnostic criteria and to rule out other conditions.
Why Choose an ADHD Assessment at One of Our Ottawa or Gatineau Clinics
For Children and Teens:
-
Difficulty focusing at school or completing homework
-
Frequent restlessness, impulsivity, or emotional outbursts
-
Trouble following instructions or staying organized
For Adults:
-
Chronic disorganization, procrastination, or poor time management
-
Difficulty sustaining attention at work or in conversations
-
A longstanding history of academic or occupational underachievement
Getting assessed can help clarify whether these challenges are related to ADHD or other underlying issues such as anxiety, learning disabilities, or executive functioning difficulties.
What to Expect from an ADHD Assessment
Psychologists in our network conduct comprehensive evaluations tailored to the client’s age and background. Assessments may include:
-
A thorough clinical interview
-
Standardized questionnaires completed by the client, parents, or teachers
-
Cognitive and attention testing
-
Review of academic, developmental, and medical history
-
Differential diagnosis to rule out other contributing factors
Once complete, clients receive a detailed report with diagnostic impressions and personalized recommendations, which may include accommodations (e.g., IEPs or workplace support), referrals, or treatment planning.

Common Questions
Is an ADHD diagnosis enough to get school accommodations?
Yes. A formal report from a licensed psychologist can support IEPs, classroom modifications, and testing accommodations such as extended time.
Can adults benefit from a diagnosis later in life?
Absolutely. Many adults find relief and validation from understanding their challenges, and a diagnosis can open the door to effective coping strategies, therapy, or medication.
Is virtual testing available?
Some components of the assessment may be conducted virtually, especially for adults, but this varies depending on the client’s needs and the psychologist’s approach. In-person testing is also available at our Ottawa and Gatineau offices.
