Orton–Gillingham was the first teaching approach specifically designed to help struggling readers by explicitly teaching the connections between letters and sounds. Today — decades later — many reading programs include Orton–Gillingham ideas.
The Orton-Gillingham Approach always is focused upon the learning needs of the individual student. Orton-Gillingham (OG) practitioners design lessons and materials to work with students at the level they present by pacing instruction and the introduction of new materials to their individual strengths and weaknesses.
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 a powerful tool of exceptional breadth, depth, and flexibility.
