What is a developmental disability?

Developmental disabilities are severe chronic disabilities that can be cognitive or physical or both. The disabilities appear before the age of 22 and are likely to be lifelong. Some developmental disabilities are largely physical issues, such as cerebral palsy or epilepsy. Some individuals may have a condition that includes a physical and intellectual disability, for example Down syndrome.


As a Senate Bill 40 Board, Callaway County Special Services is bound by Missouri State Statute definitions (i.e. 630.005 & 178.900 Revised Statutes State of Missouri) of a developmental disability that is attributable to:

  • Intellectual Disability
  • Cerebral Palsy
  • Autism
  • Epilepsy
  • A learning disability related to brain dysfunction
What is an intellectual disability?

Intellectual disability or ID, formally known as mental retardation, involves the cognitive part of a developmental disability, that is, a disability that is broadly related to thought processes.  

There are three major criteria for determining an intellectual disability:

  • significant limitations in intellectual functioning (IQ is below 70-75)
  • significant limitations in two or more adaptive areas (social, conceptual, and communication skills)
  • and onset before the age of 18
What is Senate Bill 40 Board (SB40)?

Senate Bill 40 is enabling legislation (205.968 through 205.972) passed by the Missouri state legislature in 1969 and is designed to allow individual counties in Missouri to approve a tax levy to provide support to persons with developmental disabilities in areas of residential, employment, and related services.

The citizens of Callaway County approved the enabling legislation in 1988.  The Commission of Callaway County appointed board members to serve on the board of directors of the Callaway County Senate Bill 40 Board on July 11, 1988. Callaway County Special Services was adopted in March 1989.
