What is the primary role of Disability Rights California, the State Council on Developmental Disabilities, and the Department of Developmental Services?

The primary role of Disability Rights California, the State Council on Developmental Disabilities, and the Department of Developmental Services is indeed to work with the regional centers to ensure quality services to support individuals with intellectual and developmental disabilities under the Lanterman Act. This act is crucial as it outlines the system of services and supports available to individuals with such disabilities, aiming to promote their autonomy and quality of life.

These organizations play a vital role in advocacy, policy development, and oversight of the services provided to individuals with disabilities. They help ensure that the services rendered are effective, meet regulatory standards, and align with the individuals' needs and preferences, promoting person-centered approaches in service delivery.

The other options describe activities that may intersect with the larger framework of support for individuals with disabilities but do not capture the comprehensive role these organizations play in enforcing quality standards and ensuring adherence to the Lanterman Act.
