NDRN's mission is to promote the integrity and capacity of the P&A and CAP national network and to advocate for the enactment and vigorous enforcement of laws protecting civil and human rights of people with disabilities. The National Disability Rights Network ( NDRN ) is the nonprofit membership organization for the federally mandated Protection and Advocacy ( P&A ) Systems and Client Assistance Programs ( CAP ) for individuals with disabilities. Collectively, the P&A/CAP network is the largest provider of legally based advocacy services to people with disabilities in the United States. Through training and technical assistance, legal support, and legislative advocacy, the National Disability Rights Network works to create a society in which people with disabilities are afforded equality of opportunity and are able to fully participate by exercising choice and self-determination. The National Disability Rights Network serves a wide range of individuals with disabilities ' including, but not limited to, those with cognitive, mental, sensory, and physical disabilities ' by guarding against abuse ; advocating for basic rights ; and ensuring accountability in health care, education, employment, housing, transportation, and within the juvenile and criminal justice systems.
