Family support provides assistance to families caring for their chi​ldren with developmental disabilities at home. The program addresses the unique needs that arise when a child has a developmental disability. Through the family support program, families determine what they need most. Families have the flexibility to choose services and providers. The program strives to help children and families remain independent, healthy and safe.​

​CIIS​ was developed in response to the needs of families caring for their children with intensive medical or behavioral needs at home. Service Coordinators for the program collaborate with individual families statewide to identify and assess needed supports. They then work together to develop plans of support while coordinating with the other government and community agencies.

CDDPs​ and CIIS provide in-home supports to children living with their families. These supports help children live at home and in their community. Staff help families plan their supports and get s​ervices.

The Children’s Extraordinary Needs Program​ is for children under 18 with very high medical or behavior needs. Parents and guardians in the program can be paid to provide care to their child.

​Host homes are family homes in the community that serve one or two children with intellectual and developmental disabilities. Host home families provide 24-hour care to maintain a child's health and safety. Host home families also help the child gain skills, meet their goals and support the child's family connections. The host home is licensed and receives training, staffing support and guidance from an endorsed provider agency.

​Residential care consists of homes providing 24-hour supports, supervision and training to children with developmental disabilities. They have 24-hour awake staffing. Services are planned, delivered and supervised within a goal of maintaining and improving a child's health and safety. They also work to increase each child's independence and self-confidence. Residential providers support children in their school programs, adult transition planning and, when it is part of the child's individual plan, preserving connection with their families.
