The Supports Intensity Scale® (SIS®) is a progressive, state-of-the-art assessment tool that helps professionals evaluate practical support requirements of a person with an intellectual disability, and plan services accordingly. Currently adopted in numerous states and countries, SIS is the only tool to provide a clear and comprehensive picture of what the client wants and what supports it takes to fulfill goals and aspirations.

The SIS measures life activities in home living, community living, lifelong learning, employment, health and safety, social activities, and protection and advocacy. The scale ranks each activity measured according to frequency (none, at least once a month), amount (none, less than 30 minutes), and type of support (monitoring, verbal gesturing).

The User’s Manual explains how to administer the Supports Intensity Scale, interpret raw scores, and use SIS in creating person-centered plans.
