Orton–Gillingham — often shortened to OG — is the original structured, multisensory approach to teaching reading. Developed nearly a century ago for struggling readers, it shaped most of the respected dyslexia methods used today. Here’s what it is and why it endures.
The core idea
OG teaches the structure of written English directly and in order, engaging several senses at once. A learner might see a letter, say its sound, and trace it — all together — so the connection is reinforced through multiple pathways.
What sets it apart
- Personalized. OG is designed around the individual learner, not a fixed script. Lessons start exactly where the student is.
- Multisensory. Sight, sound, and movement work together to lock in learning.
- Sequential and cumulative. Skills are introduced in a logical order, each building on the last — no skipping ahead.
- Diagnostic and responsive. The tutor continually checks for mastery and reteaches as needed.
- Emotionally supportive. Good OG teaching is patient and encouraging, rebuilding confidence along with skill.
A typical lesson
An OG-style session often moves through familiar parts: a quick review of known sounds, the introduction of a new concept with multisensory practice, work on reading and spelling words that use it, and reading connected text to apply the skill. The structure is consistent, which itself is reassuring for learners.
OG isn’t a rigid program — it’s a flexible approach a skilled tutor adapts to each learner.
Is it right for your child?
OG-based instruction is widely considered a gold standard for dyslexia, and its principles benefit most struggling readers. What matters most is a knowledgeable, patient tutor who can tailor the approach. If you’d like to see what it looks like for your reader, a free consult is a good place to start.
