Autism Spectrum Disorder Assessment

An Autism Spectrum Disorder assessment is a comprehensive psychological evaluation that explores an individual’s development, communication, social interaction, behaviour, interests, sensory experiences, and everyday functioning.


Autism assessments are available for 12+, adolescents, and adults. The process is adapted to the individual’s age, communication style, needs, and reason for seeking an assessment.


Depending on the referral question, the assessment may include:


  • Clinical and developmental interviews
  • Standardized questionnaires
  • Structured observation
  • A review of medical, developmental, educational, or treatment records
  • Information from parents, caregivers, partners, teachers, or other relevant individuals
  • Assessment of social communication and interaction
  • Exploration of behaviour, interests, routines, and sensory experiences
  • Consideration of other conditions that may explain or contribute to the individual’s experiences


Autism is not identified through one characteristic or test alone. The assessment considers information from several sources to develop a complete understanding of the individual’s strengths, experiences, and support needs.


Following the assessment, the findings are discussed during a feedback appointment. When appropriate, a written report may include diagnostic clarification and individualized recommendations for home, school, work, relationships, and community participation.
