Autism Spectrum Disorder (ASD)

What it is

A formal exceptionality, identified by an Identification Placement and Review Committee (IPRC), in the category of Communication and a diagnosed condition.

Autism Spectrum Disorder (ASD), or Autism is a diagnosis characterized by deficits in social communication and restricted, repetitive behaviours/interests, that are present since a young age and persistent. In the past, subtypes of ASD like Asperger’s and Autistic Disorder were considered separate diagnoses, but the 5th Edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-v) removed these subtypes. Now a severity level is included with an ASD diagnosis (Level 1: Requiring support, Level 2: Requiring substantial support and Level 3: Requiring very substantial support). ASD is caused by combinations of genetic and environmental factors.
