Resources > Supports Intensity Scale (SIS) and PA Plus (PA+)

The SIS evaluates support needs throughout many life areas.

The Supports Intensity Scale (SIS) is an assessment tool that evaluates the practical support requirements of a person with a developmental disability. The SIS evaluates support needs throughout many life areas.

PA Plus (PA+)—Additional questions that may be created by Pennsylvania as an addendum to the SIS. These additional questions address areas that the SIS itself did not address fully. ODP uses the SIS and PA+ as the standardized needs assessment for the Pennsylvania intellectual disabilities/mental retardation system (for Consolidated and P/FDS Waiver participants ages 16-72).
