Mission Statement

The mission of the South Dakota Developmental Center is to provide individualized treatment services and supports to people with developmental disabilities and challenging behaviors only when needed services are not available in a community setting.

We believe that all people with developmental disabilities have the same rights, responsibilities and opportunities afforded others, including protection from abuse and harm caused by self or others.

We believe that all people with developmental disabilities have the capacity for growth and development.

We believe that the most positive and the least restrictive procedures should be used when teaching people.

We believe in improving the quality, efficiency, and effectiveness of services by developing and monitoring of annual treatment goals and objectives.

We believe that employees should have a work atmosphere where they are listened to and know that they make a difference.

We believe that SDDC is an important part of the entire developmental disability delivery system in South Dakota.

We believe in fostering cooperative relationships with other providers to ensure people with developmental disabilities have the best possible life.

We will comply with all state and federal rules and regulations pertaining to SDDC.


SDDC will incorporate Person Centered Practices to:

  • Foster a learning environment that supports a cooperative partnership resulting in people having positive control over their lives.
  • Utilize practices that assist in determining what is important "to" each person served in addition to what is important "for" the person.
  • Enhance, reinforce, and strengthen a person's natural supports whenever possible.
  • Promote independence and instill a sense of self-determination and well-being.
  • Provide high-quality standards of services which support a therapeutic environment and result in a balanced life for the person.
