Fit

Who this assessment is designed for

An adult ADHD assessment is most valuable when the question is specific, and the outcome needs to be actionable.

You want clarity, not guesswork

You have persistent attention, organization, or follow-through challenges and want a structured clinical answer rather than self-diagnosis.

You need documentation

You may need documentation for workplace supports or academic accommodations, or for your own long-term planning.

You want practical next steps

You want a report that connects symptoms to real-life impact and gives recommendations you can implement.

Process

What the assessment includes

A structured process designed to support an accurate clinical formulation and clear documentation.

1) Intake + history

We gather background and current concerns, including functional impact across settings (work, relationships, daily life), and relevant developmental and medical context.

2) Clinical interview

A clinician-led interview focused on ADHD symptom patterns, duration, onset, and impairment, while considering alternative or overlapping explanations.

3) Standardized measures (as appropriate)

Structured rating scales and evidence-based measures may be used to support the clinical picture and strengthen documentation.

4) Written report + recommendations

A clear, organized report with findings and practical recommendations. Where appropriate, documentation language is written in a way that is useful for real-world supports.

Virtual and in-person options

Virtual assessments are available across Ontario. In-person appointments are available in the GTA when clinically appropriate.
