About the OG Approach

The Orton-Gillingham approach is a multisensory phonics-based approach to reading, writing and spelling.

The Orton-Gillingham approach is a multisensory phonics-based approach to reading, writing and spelling.

It provides:

  • Explicit instruction in the written code of the English language.
  • One-to-one tutoring that allows constant interaction between the tutor and student to maximize learning each tutoring session.
  • A sequential step by step approach that is success oriented.
  • A positive learning environment that centers on enabling students to become self-correcting and independent learners.

The Orton-Gillingham approach to therapeutic tutoring can benefit:

  • Students who are struggling with reading, writing and/or spelling and performing below their expected level in these areas.
  • Students who have not been successful with other reading programs.
  • Students who are dyslexic.
  • Students who guess at words or struggle to read unfamiliar words.

These persons can succeed when those responsible for their success:

  • Understand language; its processing; production and structure.
  • Understand the nature of a specific language difference and its ramification.
  • Understand the way dyslexics learn.

Studies Show

Recent studies by the National Institute of Child Health and Human Development (NICHD) in the United States have concluded that the best strategy for preventing and correcting reading problems is explicit, systematic instruction that emphasizes:

  • Early letter knowledge and phonemic awareness. Instruction in letter-sound correspondence and spelling generalizations.
  • Opportunity and encouragement to use spelling-sound knowledge in reading and writing.
  • Daily sessions for supported and independent reading with attention to fluency and comprehension.
  • Active exploration of concepts provided in written text.

The Orton-Gillingham approach meets all of these criteria.
