Intellectual disability is a developmental disability, which refers to significant limitations to a person’s level of functioning. This may involve delayed intellectual growth, inappropriate reactions to one’s environment and below-average performance in academic, psychological, physical, linguistic and social areas (Beirne-Smith, Ittenbach & Patton (2002) in Westwood, 2004 pg 133). Intellectual disability can be categorised into mild, moderate, severe and profound impairment.
Assessment for an intellectual impairment can focus on determining the following:
- Does the person have an intellectual disability?
- What is the person’s current skill level?
- What level of support does the person require?
Psychologists can utilise a range of norm and criterion referenced assessments in order to assist with assessment and diagnosis.
