 According to the Arrowsmith School's official website, the program can be used by children and adults with learning disabilities such as dyslexia, dyscalculia and dysgraphia who have at least average intelligence, but it is not suitable for people who have an autism spectrum disorder or an acquired brain injury.The program was founded by Barbara Arrowsmith Young while she was a graduate student at the Ontario Institute for Studies in Education.As a child she had exceptional visual and auditory memory, but it was coupled with several severe deficits in other areas, including dyslexia, dyscalculia, and problems with spatial reasoning, logic, and kinesthetic perception.
