Services of a Psychologist

Psychoeducational assessments are often recommended when a child exhibits behavior problems in school, low motivation, disorganization, low achievement, and/or attention difficulties. Psychoeducational assessments can determine the presence of a learning disability, developmental disability, attention disorders, or a diagnosis that explains why learning challenges occur. Our team will assess a person's individual cognitive and academic strengths and weaknesses to assist with educational planning. A psychoeducational assessment may include one or more of the following:

  • Emotional Behavioral
  • Self Help and Adaptive
  • Cognitive
  • Academic

Multidisciplinary Team - MDT

Psychologists lead a team that offers comprehensive assessments for Autism Spectrum Disorder (ASD) which involves multiple components or sources of information. The gold standard for assessing autism includes the Autism Diagnostic Observation Schedule (ADOS-2).

(ADOS-2), if often used with a comprehensive developmental interview with the caregivers (Autism Diagnostic Interview - Revised; ADI-R). Best practice often includes an assessment of cognitive skills and other areas that require more knowledge. This information is particularly helpful in guiding parenting strategies and learning at school.
