What is a developmental disability?

According to the Developmental Disability Act (DD Act), the term developmental disability (DD) means a severe, chronic disability that occurs before an individual is 22 that is likely to continue indefinitely and results in substantial functional limitations in three or more of the following areas of major life activity: self-care, receptive and expressive language, learning, mobility, self-direction, capacity of independent living, economic self-sufficiency. These impairments require the individual to sustain lifelong or extended supports or assistance. Diagnosed conditions may include autism, Down syndrome, cerebral palsy, or spina bifida.

Who we are

The Idaho Council on Developmental Disabilities (ICDD) is an outcomes-oriented, mission-driven organization.  We lead the way in our state in advancing issues that improve the lives of people with intellectual and developmental disabilities (I/DD) and their families by actively listening to all stakeholders, identifying and exploring emerging trends, and proactively reaching out to collaborate with a variety of leaders and organizations to develop effective solutions.

The Council advocates with and on behalf of Idahoans with developmental disabilities by listening to their concerns and working to help them improve their lives by building service systems and natural supports that enable them to live lives of independence, responsibility, meaning, and contribution.


All Idahoans participate as equal members of society, empowered to reach their full potential as responsible and contributing citizens of their communities.


The mission of the Idaho Council on Developmental Disabilities is to promote the capacity of people with developmental disabilities and their families to determine, access, and direct the services and/or support they need to live the lives they choose, and to build the communities ability to support their choices.
