The Massachusetts Alliance for 21st Century Disability Policy (MA21) was formed with the mission of advancing full community participation for individuals with disabilities. MA21 is a partnership between several advocacy organizations that aims to create a consensus policy framework to improve public policies for people with disabilities and their families. The document outlines guiding principles for disability policy, such as individuals directing their own supports and families receiving necessary assistance. It also identifies barriers like bureaucracy and recommends strategies like enhancing family supports and ensuring inclusive education.
