Diagnostic Testing


Asbergers Testing

Disability Testing


Psychological diagnostic assessments are completed for a variety of reasons, but the main goal is to assess an individual's emotional and behavioural symptoms in order to identify and, if necessary, diagnose any psychological disorders. Diagnosing psychological disorders is a controlled act in Ontario, restricted to Psychologists, Psychological Associates, and Physicians.

A psychological assessment usually will consist of two parts: a clinical interview and psychometric testing. The overall duration of the assessment will vary in length depending on each individual, but a typical psychological assessment will last 2 to 4 hours. If necessary, this may be split into multiple sessions.

Following the assessment itself, a comprehensive report will be completed.  It will contain information about the individual's background, symptoms, diagnoses, prognosis for recovery, and recommendations for treatment. A follow-up session will then be scheduled. This session will include a review of all the information and address any questions or concerns one might have.
