He previously served on PCPID under Presidents George W. Bush and Barack Obama, including a term as Chairman from 2011–2013. In 2016, Congress appointed him to the National Council on Disability. He is also currently the Chair of the Governor’s Commission on Intellectual Disability, and the Chair of the Massachusetts Disabled Persons Protection Commission. In 2013, the University of Massachusetts Boston established the James T. Brett Chair in Disability and Workforce Development, the nation’s only endowed chair in disability and workforce development. In 1996, Bay Cove Human Services of Boston named a new community home for disabled adults “Brett House” in his honor.
