Every March, the National Association of Councils on Developmental Disabilities (NACDD) and its partners collaborate to lead Developmental Disabilities Awareness Month (DDAM), an annual campaign highlighting how people with and without disabilities form strong communities together. Established in 1987 by President Ronald Reagan, Developmental Disabilities Awareness Month highlights the importance of fostering a society where people with disabilities are empowered to contribute to their communities. NACDD's 2025 theme, We’re Here All Year, focuses on how people and programs are always contributing, not just during this observance.
