The Orton-Gillingham intervention model is a structured, multisensory approach designed to help struggling readers, particularly those with dyslexia, improve their reading, writing, and spelling skills. Developed by Samuel Orton and Anna Gillingham, it combines explicit, systematic teaching of phonics, phonemic awareness, vocabulary, fluency, and comprehension using visual, auditory, and kinesthetic/tactile methods. The model is tailored to meet the individual needs of each learner, offering personalized instruction that progresses at a pace suited to the student’s abilities. The Orton-Gillingham method is often used in one-on-one or small-group settings and is based on the principles of direct, repetitive, and cumulative learning.
