What Is the Orton-Gillingham Approach? A Parent's Guide

The Orton-Gillingham approach is a structured, multisensory way of teaching reading and spelling, developed specifically for children with dyslexia. Instead of expecting children to absorb reading naturally, it teaches the English language explicitly and systematically, one skill at a time, using sight, sound, and movement together. It is the foundation of most evidence-based dyslexia intervention used around the world today.

Where does Orton-Gillingham come from?

The approach is named after neuropsychiatrist Dr. Samuel Orton, who studied why intelligent children struggled to read in the 1920s, and educator Anna Gillingham, who turned his research into a teachable method. Nearly a century of refinement later, its core insight still holds: children with dyslexia can absolutely learn to read. They just need the code of written English taught to them directly, rather than left for them to infer. Most of the structured literacy programmes you may have heard of, such as Wilson, Barton and Slingerland, are built on Orton-Gillingham principles.

What makes it different from regular tuition?

Most tuition re-teaches schoolwork: the same content, delivered again, a little slower. Orton-Gillingham goes back to the foundations of how written English works and rebuilds them properly.

• It is explicit. Nothing is assumed. Every sound-letter relationship, spelling rule, and syllable pattern is taught directly.
• It is systematic and cumulative. Skills are taught in a deliberate order, from simple to complex. Each new lesson builds on skills the child has already mastered, so the foundation never has holes.
• It is multisensory. Children see a letter pattern, say its sound, hear it in words, and write it, often all within the same activity. Engaging multiple senses builds stronger, more durable memory pathways.
• It is diagnostic and prescriptive. The teacher constantly assesses what the child has actually mastered and adjusts the next lesson accordingly. The programme follows the child, not a fixed syllabus.

Orton-Gillingham does not re-teach schoolwork. It rebuilds the foundations of written English, one mastered step at a time.

Who does it help?

Orton-Gillingham was designed for children with dyslexia, but it helps any child who struggles with reading and spelling: children who guess at words, read fluently but spell poorly, or avoid reading altogether. Because it starts from each child’s actual skill level, it works whether the gaps are small or significant.

What does an Orton-Gillingham session look like?

A typical 1:1 session moves through short, connected activities, each a few minutes long, and every one of them chosen for that one child based on what the previous session showed. Here is the shape of a 45-minute session in my own practice.

We open with a card drill. I show letter and letter-pattern cards, and the child gives each sound from memory. It takes three minutes and warms up every pathway the rest of the session will use. Then the drill reverses: I say a sound, and the child repeats it and writes the letters that spell it, saying them aloud as she writes. Sight, sound and movement, all working on the same link.

Next comes blending, pushing individual sounds together into words, followed by the teaching point of the day: perhaps a new letter pattern, perhaps a spelling rule, introduced concretely and practised immediately in words the child can already handle. Then the child reads words, phrases and a short passage built only from patterns she has been taught. Nothing on the page is beyond her. We finish with dictation, from sounds to words to full sentences, and a few minutes of connected reading, so the session always ends on success.

Children usually find the sessions surprisingly enjoyable, which surprises parents more than anything else. The work is achievable by design, the activities change every few minutes, and success builds motivation. A child who has spent years failing at print discovers, sometimes within the first month, that she can read every word on the page in front of her.

How do I know it is working?

Progress arrives in a reliable order. Attitude moves first: less resistance before sessions, more willingness to pick up a book, fewer tears over homework. Accuracy comes next, on the patterns that have been taught, and you will hear it in slower but correct sounding-out where there used to be guessing. Then the skills start showing up outside the lesson, in school readers and spelling tests. Spelling is usually the last thing to settle, and that is normal.

Because the approach is diagnostic, mastery is checked continuously. If the child has not mastered something, it is retaught a different way until she has. The child is never blamed for a lesson that did not land; the lesson is redesigned.

How long does it take to see results?

Most families see early changes within the first few weeks: better confidence, more willingness to try, stronger phonics. Meaningful, lasting change takes longer. Structured literacy programmes typically run 12 to 24 months, depending on the child’s starting point. The pace is set by mastery, not by a calendar.

How do you choose an Orton-Gillingham teacher?

Because “Orton-Gillingham” is an approach rather than a brand, anyone can claim the label. A few questions separate trained practitioners from tuition with new packaging. Ask what training and certification the teacher holds, and how many one-to-one intervention hours sit behind it. Ask whether sessions are truly 1:1, how progress is measured, and whether the reading material is decodable, meaning built only from patterns the child has been taught. Ask whether spelling is taught alongside reading; in a genuine Orton-Gillingham programme it always is.

Be careful with anyone promising a fix in weeks. Rebuilding a child’s literacy foundation is steady work, and honest practitioners say so. A good specialist will also want to look before teaching: an informal assessment of reading and spelling shows where the gaps begin and what the first months of the programme should contain.

Frequently asked questions

Is Orton-Gillingham only for children with a dyslexia diagnosis?

No. A formal diagnosis is not required. The approach helps any child with foundational gaps in reading or spelling, and because assessment happens continuously, it adapts to whatever the underlying difficulty turns out to be.

Does Orton-Gillingham work online?

Yes. With a trained teacher, 1:1 online sessions preserve everything that matters: explicit teaching, multisensory activities, and continuous assessment. At Flourishing Kids, families across India, the UAE, Oman, Singapore, Australia and the US learn this way every week.

How is this different from phonics at school?

School phonics is taught to a whole class at one pace, and moves on whether or not every child has mastered the material. Orton-Gillingham is taught 1:1, at the child’s pace, with every gap identified and filled before moving forward.

Is Orton-Gillingham a programme I can buy?

No. It is an approach: a set of principles a trained teacher applies to one child at a time. Packaged programmes built on those principles exist, but the teacher’s training and the 1:1 diagnostic teaching are what do the work, not a box of materials.
