An Act relative to persons with developmental disabilities

This bill updates the legal definition of a person with a developmental disability in Massachusetts to clarify who qualifies for state services. It applies to individuals aged five and older who have a severe, chronic impairment that began before age 22 and limits their ability to perform at least three major life activities, such as self-care or learning, as well as younger children with conditions likely to result in such disabilities without intervention. The legislation also explicitly states that having a developmental disability does not automatically mean a person is mentally ill, ensuring these groups are not misclassified for care purposes. These changes will officially take effect on January 1, 2025.
