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.

The SIS was developed by 10 disability experts over five years and consists of an 8-page Interview and profile form that tests support needs in 57 life activities and 28 behavioral and medical areas.

*Purchase of SIS materials is limited to qualified users of the tool. If you have questions about SIS assement qualifications, contact us.
