In March of 1963, parents of children with learning disabilities representing local support groups from around the country gathered in Chicago for a national conference. These concerned families organized into a national organization which was incorporated in 1964 as the Association for Children with Learning Disabilities (ACLD). From those beginnings, the Learning Disabilities Association of America has grown to serve tens of thousands of members with learning disabilities, their families and the professionals who work with them.
