The AACCENT Act establishes a federal grant program to create three geographically diverse National Resource Centers focused on augmentative and alternative communication (AAC) for people with significant expressive communication disabilities—those who cannot be understood through spoken words alone. Eligible organizations must be nonprofit partnerships led by people with communication disabilities, partnered with higher education institutions or professional associations, and guided by advisory councils composed entirely of individuals with these disabilities. The program will distribute up to $9 million annually per five-year grant period to centers that train educators, healthcare providers, law enforcement, and other professionals on AAC tools and supports, with priority given to organizations with at least three years of AAC experience and meaningful involvement of AAC users in leadership. Congress authorizes $9 million annually from fiscal years 2027 through 2031 to support these centers' operations, coordination with federal agencies, and dissemination of information about augmentative and alternative communication services.
