The National Core Indicators (NCI) Survey


The National Core Indicators (NCI) Survey is used by the California Department of Developmental Disabilities to assess performance in services and supports provided to people with intellectual/developmental disabilities (I/DD). The NCI survey has been used in California since 2010 as a requirement by the Welfare and Institutions Code, Section 4571 to implement a nation-wide quality assessment survey.

The survey was developed by the Human Services Research Institute and the National Association of State Directors of Developmental Disabilities Services (NASDDDS) and is used in 48 states and Washington, D.C. In California, the NCI Survey is conducted by the State Council on Developmental Disabilities (SCDD).

The survey asks questions about these areas of an individual’s life:

  • Residence
  • Employment
  • Relationships
  • Involvement in the community
  • Information and Planning
  • Health and Welfare
  • Safety
  • Respect and Rights
  • Access to services and supports
  • Satisfaction of services
  • Choices, decision making and control
