"The Orton-Gillingham Approach is a direct, explicit, multisensory, structured, sequential, diagnostic, and prescriptive way to teach literacy when reading, writing, and spelling does not come easily to individuals, such as those with dyslexia.  It is most properly understood and practiced as an approach, not a method, program, or system. In the hands of a well-trained and experienced instructor, it is a powerful tool of exceptional breadth, depth, and flexibility."
