About Us

In 1949, a group of parents formed a non-profit organization called Mentally Retarded Children’s Aid (MRCA) to provide functional education for their children.  At that time, children with developmental disabilities were not being allowed to remain in public schools because they did not pass standard IQ tests.  The parents were convinced their children could learn and were determined to give them the opportunity to do so.  Through the hard work of these parents and the cooperation of the surrounding community, teachers were hired and training classes were begun in the basement of a church.

This group of parents joined parents nationwide who shared the same determination to have their children educated.  They demanded equal education for all children regardless of their abilities.  They fought long and hard.  Ultimately, they were instrumental in the enactment of Public Law 94-142.  The creation of state ARC's (Association for Retarded Citizens) was another accomplishment of these parents.  They were then, and are now, the vanguards of services for individuals with developmental disabilities.
