Background information your ho their potential The hyde school In 1966, Joseph W. Gauld founded the first Hyde school in Bath, Maine in response to a system of education which hebelieved was failing its children because of conflicting priorities. His search for a new approach in education led to a program that valued attitude over aptitude, effort over ability, and s
