California’s regional centers are a network of 21 community-based non-profits, represented by the Association of Regional Center Agencies (ARCA). The regional centers coordinate services for, and advocate on behalf of, nearly 400,000 Californians with developmental disabilities. The mission of ARCA is to promote, support, and advance regional centers in achieving the intent and mandate of the Lanterman Developmental Disabilities Services Act in providing community-based services that enable individuals with developmental disabilities to achieve their full potential and highest level of self-sufficiency. The Association functions as a leader and advocate in promoting the continuing entitlement of individuals with developmental disabilities to all services that enable full community inclusion. The Association also participates in the development of public legislative policy and serves as a focal point for communication, education, training, and prevention services.
