The mission of The Arc of Rensselaer County is to advocate for the rights and safety of individuals of all ages who have an intellectual disability and/or a developmental disability or delay.

The Arc is a source of support, specialized knowledge, and available resources in assisting individuals and their families to meet their needs and goals.

The Arc works to influence societal attitudes and governmental policy so that people with intellectual and developmental disabilities will have access to the services, assistance, and opportunities they need for personal growth and development, and participation in the community.
