Diagnostic Assessment

Diagnostic assessment is a process in which a highly trained individual or team of experienced clinicians seek to determine whether a person demonstrates behaviours or symptoms that would meet criteria for a formal diagnosis. Families are often seeking to know whether their child or family member has a certain condition; would like a second opinion after their child has already been assessed by another clinician; or are wanting answers to why their child is or is not acting or developing in a certain way.


Diagnostic assessment includes:

  • A comprehensive review of previous reports and records from school, medical doctors and specialists.

  • Interview and review of developmental history and the current concerns of the family and child.

  • Consultation with those already providing services to the client (i.e., speech therapist, school teacher, psychologist, psychiatrist, medical doctor).

  • Administration of standard tests including diagnostic tests specific to the family and child’s concerns.

  • Observation of the individual in different environments if relevant (i.e., home observation, school observation, observation with peers).

  • Full written report including background information, observations of the client, results of standardized tests, diagnostic impressions, and recommendations.

  • Feedback session with family to review the findings within the written report and answer questions.
