What Is the Orton-Gillingham Approach to Reading — and Does It Work?

If you have ever sat across from a reading specialist or a teacher and heard them say "your child would benefit from an Orton-Gillingham approach," you probably walked away with more questions than answers. The term sounds technical, maybe even intimidating. But the idea behind it is straightforward — and once you understand it, you will have a reliable framework for evaluating any reading curriculum you encounter. Here is a plain-language explanation of what the Orton-Gillingham approach is, who it helps, and what to look for in a program that uses it.

Who were Orton and Gillingham?

In the 1920s, a neurologist named Samuel Torrey Orton began studying children who struggled to read despite normal intelligence and conventional instruction. He observed patterns in their errors — letter reversals, difficulty connecting sounds to symbols, inconsistent word recognition — and concluded that these children were not failing because of low ability. They were failing because the way reading was being taught did not match how their brains

processed language.

Anna Gillingham was an educator and psychologist who shared Orton's convictions. Working together, they developed a structured, systematic approach to reading instruction that engaged multiple senses simultaneously and built skills in a deliberate, logical sequence. Their collaboration laid the foundation for what we now call structured literacy — the research-backed framework that reading specialists, schools, and curriculum developers across the country are rallying around today.

The core principles of the Orton-Gillingham approach

What distinguishes OG from other reading methods is not a single technique but a set of interlocking principles that work together. A genuine Orton-Gillingham phonics program should embody all of the following:

• Multisensory — students engage sight, sound, and touch at the same time. Saying a phonogram aloud while writing it and seeing it in print creates stronger, more durable memory than any single-channel approach.

• Systematic and sequential — phonics patterns are taught in a deliberate order, from simple to complex, with nothing introduced before its prerequisite is secure.

• Explicit — every concept is taught directly. Nothing is left to discovery, inference, or the hope that students will absorb patterns through exposure alone.

• Diagnostic and prescriptive — instruction responds to the individual student. Lessons are adjusted based on what the student has and has not yet mastered.

• Cumulative — each new lesson begins with a review of everything previously taught. Skills build on one another continuously rather than being taught in isolated units.

• Phonics-based — letter-sound relationships are the foundation. Students learn to decode words by understanding how the sounds of spoken language map to the letters and letter combinations of written language.

This is what separates the OG reading method from approaches built on memorization, context guessing, or whole-word recognition. OG gives students the tools to decode any word they encounter — not just the ones they have memorized.

Who benefits from Orton-Gillingham instruction?

The honest answer is: all beginning readers benefit from instruction built on these principles. Explicit, systematic phonics instruction delivered in a cumulative, multisensory format is simply better teaching for virtually every child learning to read.

That said, students with dyslexia benefit especially. Dyslexia is a language processing difference that makes it difficult to connect sounds to print using conventional instruction. The OG approach was designed specifically for these students, and decades of research confirm it is among the most effective interventions available. Reading specialists and educational psychologists routinely recommend OG-aligned programs as a first response when a child is struggling.

Multisensory reading instruction is also widely used in RTI and MTSS frameworks — the tiered intervention systems used in schools to support students who are not progressing at the expected rate. OG-aligned programs are commonly placed at Tier 2 and Tier 3, where students need more intensive, targeted support than whole-class instruction can provide. If your school or specialist has recommended an OG approach for your child, they are describing exactly this kind of structured, individualized phonics intervention.

What to look for in an OG-aligned curriculum

Not every program that claims OG alignment delivers on the promise. When evaluating any curriculum, look for three things:

Scripted, sequential lessons with a clear phonogram scope and sequence. The program should be able to show you exactly which phonograms are taught at each level and in what order. If the sequence is unclear or arbitrary, the cumulative principle is not being honored.

Genuine multisensory activities — not just worksheets. Saying, writing, tracing, building words with tiles or magnetic letters, and reading aloud are all multisensory. A stack of fill-in-the-blank pages is not. The best programs integrate kinesthetic and auditory practice throughout each lesson, not as an add-on.

Decodable practice texts that match the phonics sequence. Students need to read books containing only the phonograms they have been taught. Without controlled decodable texts, the phonics instruction and the reading practice are disconnected — and disconnected practice does not build fluency.

How Readers in Rhyme aligns with OG

Readers in Rhyme is an OG-aligned classical phonics curriculum — not a certified Orton-Gillingham program, but one built on the same principles. The curriculum teaches all 74 phonograms in a systematic, cumulative sequence across five levels. Scripted lessons guide teachers through explicit instruction at every stage, and multisensory activities are woven into each lesson rather than treated as supplements.

The 80 decodable readers are sequenced to match the phonogram instruction exactly, so students are never asked to read a pattern they have not been taught. Inside each reader, phonograms are color-coded — red for vowel sounds, blue for consonants — giving students a consistent visual reference as they read.

Readers in Rhyme also aligns with several OG-adjacent programs that schools may already be using. Alignment guides are available for Spalding, Logic of English, UFLI Foundations, and Literacy Essentials, making it straightforward to use Readers in Rhyme alongside any of these existing curricula.

OG works because the brain responds to it

The Orton-Gillingham approach has lasted a century because it is built on how the reading brain actually works — not on assumptions about how children should be able to learn. Explicit instruction, multisensory engagement, and cumulative review are not teaching preferences. They are the conditions under which the brain most reliably forms the phonics knowledge that fluent reading requires.
