Tailoring supports for individual needs requires tools that reliably and validly measure those needs. That is the function of AAIDD’s Supports Intensity Scale (SIS)®
SIS measures the individual’s support needs in personal, work-related, and social activities in order to identify and describe the types and intensity of the supports an individual requires. SIS was designed to be part of person-centered planning processes that help all individuals identify their unique preferences, skills, and life goals.
The supports approach also recognizes that individual needs change over time, and that supports must change as well. They must be developed and delivered in age-appropriate settings, with the understanding that, regardless of intellectual abilities or limitations, people should have the opportunity engage in activities and life experiences just like any other person.
