Course summary

This intensive one-day Master Class has been designed to increase participant’s knowledge and skills in the diagnostic assessment of children and adolescents with ASD Level 1 and Level 2, including the Asperger’s syndrome sub-type.  Participants will learn how to conduct a diagnostic assessment for a child or adolescents to determine whether that child is on the autism spectrum, including measurement of comorbidity, differential diagnosis, use of psychometric assessment, and both written and oral reporting or results to parents, teachers and the child.

Teaching process

The course material is presented using a combination of didactic teaching, taped demonstrations from real life clinical sessions, case studies, and question time. Each day is a stand-alone workshop, and participants may choose to choose either one or both workshops. There are several Handouts included to assist clinicians in their practice and to supplement the teaching process.

Who will benefit?

Health and educational professionals, including psychologists, teachers, teachers assistants, occupational therapists, speech pathologists, GPs, paediatric psychiatrists and paediatricians.
