Intellectual Disability

A student with an intellectual disability is one who has been determined to have significantly sub-average intellectual functioning as measured by a standardized, individually administered test of cognitive ability in which the overall test score is at least two standard deviations below the mean, when taking into consideration the standard error of measurement of the test; and concurrently exhibits deficits in at least two of the following areas of adaptive behavior: communication, self-care, home living, social/interpersonal skills, use of community resources, self-direction, functional academic skills, work, leisure, health, and safety.
