Supports Intensity Scale - Children's Version



What is the SIS-C?

The Supports Intensity Scale - Children's Version® (SIS-C®) is a standardized assessment tool designed to measure the pattern and intensity of supports that a child aged 5 to 16 years and older with intellectual and developmental disabilities (IDD) requires to be successful in age-appropriate community settings.

For a child with IDD, there may be a mismatch between what a child is able to do and the environmental demands placed on the child, which results in a need for types and patterns of support that most other children do not need.

The SIS-C provides measures that are specific to the support needed by children in typical, age-appropriate environments. It reflects the general measurement framework, rating system, and common support need domains as the Supports Intensity Scale - Adult Version®  (SIS-A®).

SIS-C Information


SIS-C Measures

The SIS-s measures an individual's 

  • Exceptional Medical and Behavioral Support Needs
  • Support Needs for Life Activities in the areas of home living, community & neighborhood, school participation, school learning, health & safety, social activities, and advocacy.

The Scale ranks each activity according to frequency, amount, and type of support needed.

The SIS-C is Different

The SIS suite of tools shift the focus from deficiencies to support needs, by evaluating the practical supports a child needs in age-appropriate settings.


The assessment is done through an interview with the person being assessed and those who have known the individual for at least three months.
