SIS-A Implementation Project

A Path for ME logo


The Department of Health and Human Services recognizes the need for a new standardized needs assessment tool for individuals with Intellectual and Developmental Disabilities (IDD) or Autism who seek services under the MaineCare Section 21 and 29 Home and Community Based Services (HCBS) waiver programs. In partnership with service recipients, families, providers, and other stakeholders, the Department is beginning a process through which a needs assessment tool can be selected and implemented. This project will begin in May 2021 and is expected to continue through March 2025.

This project is part of reform work that is already underway at the Department’s Office of Aging and Disability Services (OADS). The implementation of this assessment tool is expected to provide fair and equitable determinations of need as well as other beneficial changes and efficiencies within the IDD service system.
