Diagnostic, Psychological, Psychoeducational and Interdisciplinary Assessments:

Which one is right for me?

To begin any assessment, the psychologist will meet with the parents to discuss the child’s history and the parents’ concerns. The purpose of the first appointment is to obtain information about your concerns for your child and to determine what key questions you would like to have covered by the assessment.

Diagnostic Assessment is a psychological evaluation aimed at determining whether or not your child meets the diagnostic criteria for a developmental disorder, such as Autism Spectrum Disorder, Attention Deficit Disorder, etc. The psychologist will use various standardized tests for cognitive skills and adaptive functioning as well as looking for specific symptomology.

Psychological Assessment is a more broadly based psychological evaluation. The psychologist will look at a broader range of developmental disorders and psychological criteria in order to determine what, if any, issues a child has. A variety of standardized tests will be used.

Psychoeducational Assessment combines the psychological/diagnostic assessment with a particular focus on issues which can affect an academic environment, such as learning disorders or sensory issues. On diagnosis, the psychologist will be able to provide a letter which can be used as part of an Individual Education Plan with the school board.

Interdisciplinary Assessment combines the psychological/diagnostic assessment with an occupational, behavioural or speech/language assessment, using an associated specialist. The report and recommendations will be done jointly by the psychologist and the specialist.


What is the process?

The process depends on your child’s age and the extent of the assessment.

For children between the ages of 12 months and 3 years, we offer a streamlined assessment process beginning with an initial intake meeting with the parents, followed by a 60-90 minute testing appointment. Using gentle, play-based testing criteria and information provided by the parents, the psychologist evaluates the child. The parents then meet with the psychologist for a separate feedback appointment to go over the diagnosis (if any) and our recommendations. A diagnostic letter will be provided at the feedback appointment and a more detailed formal report will be completed 8-10 weeks after the feedback.

For children between the ages of 3 and 21, the number of appointments vary according to which psychologist the family sees.  Each assessment will begin with a parent intake, followed by 2 to 4 testing sessions of various lengths, and a parent feedback appointment.  Generally, between 3 and 6 hours are allotted for testing.  For older children, a separate feedback for the child and the psychologist may be requested.  If required, a family may also request multiple intake or feedback appointments, if such would make the assessment easier.  A diagnostic letter can be provided at the feedback appointment and a more detailed formal report will be completed 8-10 weeks after the feedback.

For adults (18 +), we book either 5 or 6 appointments, depending on the psychologist.  The first is an intake, followed by either three or four 60-90 minute testing appointments, and then a feedback.  It is also possible to request multiple intakes or feedbacks, at the family’s request (i.e., one for the parents and one for the client), however, families should be aware that if a client is over 18, it is their decision as to whether or not information can be shared with other parties, including parents.  A diagnostic letter can be provided at the feedback appointment and a more detailed formal report will be completed 8-10 weeks after the feedback.

Psychoeducational assessments will sometimes require extra appointments or observation sessions. We will book the standard number of appointments at intake but may require additional sessions if needed.

Interdisciplinary assessments will require extra appointments with the chosen specialists. We will help your family to arrange and coordinate these appointments.


What are the costs and wait times?

The costs and wait times for an assessment vary depending on the number of appointments.  Our psychologists charge $ 225 per hour.  A streamlined assessment is generally 3 to 4.5 hours, plus a 4 hour charge for the report.  For older children and adults, an assessment can be 6 to 9 hours, plus a four hour charge for the report.  Extra intake and feedback sessions or observations would increase the amount of time necessary.  An interdisciplinary assessment’s costs vary depending on the chosen specialist.

Please note that the costs cited above are general estimates only and are subject to change depending on individual circumstances.

Wait times can vary depending on the clinician.  Please contact the clinician’s administrative assistant to find out what the wait times are. (List of who to contact is below.)

How long does the assessment take?

We try to have a minimum of 1 week in between each appointment. This prevents any outside events (stress, illness, frustration) from unduly influencing the results and minimizes the stress on the child. There is usually a two or three week wait between the final testing session and the feedback, to give the psychologist time to review all of the testing data.  The final report should be available 8-10 weeks after the feedback.
