Which key indicator is associated with the disability category of intellectual disability?

The key indicator associated with the disability category of intellectual disability is significantly below-average cognitive skills and adaptive behavior. This criterion is fundamental in identifying intellectual disabilities, as it encompasses both the cognitive aspects—reflected in an intelligence quotient (IQ) score that falls significantly below the standard—and the practical, everyday skills needed for functioning in various environments, such as social, academic, and daily living situations.

When evaluating for intellectual disability, professionals typically assess not just cognitive abilities but also how individuals cope with everyday challenges, including communication, self-care, and social skills. This dual focus ensures that the label of intellectual disability accurately reflects an individual’s overall capacity to function effectively in society.

In contrast, other options might reflect various conditions or factors but do not encapsulate the specific defining characteristics of intellectual disability. For instance, psychological assessment results, while important in understanding a person’s overall mental health, do not exclusively denote intellectual disability. Lasting physical impairment pertains more to physical disabilities, and chronic emotional dysregulation, while it can occur alongside intellectual disability, does not serve as a primary indicator for the category itself.
