The Arrowsmith School is a private school in Toronto, Ontario, for children in Grades 1 to 12 and adults with learning disabilities. The original Arrowsmith School was founded in Toronto in 1980 by Barbara Arrowsmith Young. A second location was opened in May 2005 in Peterborough, Ontario. The Eaton Arrowsmith School, which is modelled on the Toronto school and founded by Howard Eaton, was opened in 2005 in Vancouver, British Columbia with two further branches established in Canada and one in the United States between 2009 and 2014.
The school's methodology, known as the Arrowsmith Program, was founded by Arrowsmith Young in 1978 from exercises that she had begun devising for herself in 1977 and which she has said enabled her to overcome her own severe learning difficulties. Her own struggle with learning disability and the rationale for her program are described in her 2012 book The Woman Who Changed Her Brain.
