The Orton-Gillingham approach is a multi-sensory way of teaching reading, spelling and writing skills to students who struggle with language-based learning difficulties, including dyslexia. Lessons focus on mastery of the smallest units of language first, including phonemes and graphemes, and then build to whole word, phrase and sentence level instruction.
Many current reading methods and courses are grounded in this approach, including Touch-type Read and Spell, and it can serve as a guide for tutors who offer literacy skills support for individuals with specific learning difficulties.
Because Orton-Gillingham focuses both on enhancing phonological awareness and teaching English language rules, it can also be useful for English Language Learner (ELL) students.
