Orton-Gillingham instruction is not a program, but a teaching approach. True Orton-Gillingham (or O-G) instruction is based on several key attributes.
The Orton-Gillingham Approach is typically presented in a one-on-one instructional model. At times interventions can be presented in a small group, but it is more successful in a one-on-one setting. The Orton-Gillingham approach focuses around Reading, spelling, and writing. Orton-Gillingham is most successful when it is based on the needs of an individual student. Students with dyslexia all struggle with different components of reading. When the intervention is individualized it can be directed to exactly what the student needs to succeed. Orton-Gillingham recognizes that students with dyslexia must be taught directly and systematically. The Orton-Gililngham Approach is multi-sensory, structured, systematic, sequentional, cumulative, and individualized. This approach explains the rules of the English language so that the students can apply the skills they have learned to reading instead of guessing.
