The diagnosis of Intellectual Disability is determined by?

The diagnosis of Intellectual Disability is determined by assessing both intellectual functioning and adaptive behavior. Intellectual functioning is typically measured through standardized IQ tests, with a score of around 70 or below indicating potential disability. Adaptive behavior is evaluated through assessments of daily living skills, social skills, and communication abilities, often using standardized questionnaires or interviews. A diagnosis is usually made when these deficits are present from childhood and significantly impact daily functioning.
