Brown v Board of Education addressed the issue of racial segregation in the schools, but opened the door for the recognition of the right to a free public education. Local parent groups started nursery and day care programs and sheltered workshops.
The emergence of the parent movement in the late 1940s and early 1950s meant that more support was available to families, though in an indirect way.
This is not to say that families were supported adequately. It is only to say that "community services" began to emerge that allowed more families to stay together.
There were few places for their sons and daughters to go during the day. In the 1950s the number of children with developmental disabilities enrolled in special educational classes doubled from the 1940s, and the number of school systems offering such services increased fourfold.
