The Supports Intensity Scale (SIS)
The Supports Intensity Scale was developed by a team of experts from the American Association on Intellectual and Developmental Disabilities (AAIDD), formerly the American Association on Mental Retardation (AAMR). The SIS measures support needs in the areas of home living, community living, lifelong learning, employment, health and safety, social activities, protection and advocacy, Exceptional Medical, and Exceptional Behavioral needs. The Scale ranks each activity in three distinct areas: type of support, frequency of support, and amount of support time. The tool measures the level of support needed for a person with a developmental disability to engage in an activity on their own, like any other individual of relative age without a developmental disability.
