We are the largest national community-based organization advocating for and serving people with intellectual and developmental disabilities and their families. We encompass all ages and all spectrums from autism, Down syndrome, Fragile X and various other developmental disabilities.

The Arc is driven by opportunity.

The opportunity for hope, for growth, for change; the opportunity for everyone to become a valued, contributing member of their community.

We strengthen people with disabilities, their parents and family members, and dedicated professionals by connecting them across our national network of community based chapters. Our collective voice provides the opportunity for all of us to make a difference.

The Arc fosters respect and access for individuals with intellectual and developmental disabilities and their families, giving them the power to achieve a full and satisfying life.
