The Orton-Gillingham Approach to reading instruction was developed in the early-20th century. It is language-based, multisensory, structured, sequential, cumulative, cognitive, and flexible.
The Orton-Gillingham Approach has been in use since the 1930s. An intensive, sequential phonics-based system teaches the basics of word formation before whole meanings. The method accommodates and utilizes the three learning modalities, or pathways, through which people learn—visual, auditory and kinesthetic. Unlike some scripted and rigid reading programs, the Orton-Gillingham Approach is a system that allows for flexibility.
