Autism Care Chitwan Society (ACCS) is a non-governmental, non-political, and non-profit organization dedicated to supporting individuals with autism. It was founded by a group of committed parents of children with autism (CWA) who recognized the need to unite at the local level to ensure better services, advocacy, and support for their children. With a shared vision of creating a more inclusive and supportive community, these parents came together to monitor and promote the rights and well-being of children and individuals with autism.

The organization was officially registered with the District Administration Office, Chitwan, on April 27, 2018, and became affiliated with the Social Welfare Council within the same year. Since its inception, ACCS has been working tirelessly to raise awareness, improve access to services, and empower families affected by autism in the Chitwan region and beyond.
