The Supports Intensity Scale (SIS®), designed by the American Association on Intellectual and Developmental Disabilities (AAIDD), is an assessment tool that effectively measures the support needs for individuals with intellectual and
developmental disabilities (IDD).
Since 2007, Ascend has partnered with states and AAIDD to develop exemplary SIS programs. As the first independent company trained by AAIDD to perform SIS assessments, Ascend is one of the most experienced and qualified SIS vendors in the nation. When states transition to the SIS, our knowledge base offers unequaled support, project management, and experience. With each of the over 35,000 SIS assessments Ascend has conducted to date, and for each one we perform in the future, Ascend is wholly committed to performing them in a person-centered, independent, manner to accurately represent each individual’s unique support and service needs.
In addition to assisting states with their SIS project’s structure, transition, implementation, or ongoing assessments needs, Ascend offers the Ascend Scheduling Assistance Program (ASAP™), a customizable web-based SIS scheduling data system that provides a systematic way for SIS respondents and participants to share their availability and also streamlines the request and approval process for urgent assessments.
