If your child is struggling with reading, spelling, or writing, you've probably started hearing the term "Orton-Gillingham" everywhere. The school mentioned it. Another parent swears by it. A therapist recommended it. But when you try to find out exactly what it is, you get a lot of educational jargon and not a lot of plain English.
Let me fix that. As a certified literacy specialist who uses Orton-Gillingham inspired methods every day with struggling readers, I can tell you what it is, what it looks like in practice, who it helps, and — importantly — what to watch out for when someone tells you they "use Orton-Gillingham."
First — What Orton-Gillingham Is NOT
This is where most explanations start going wrong, so let's clear it up first.
Orton-Gillingham is not a specific program or curriculum. It's not a box of materials you buy, a textbook, or a software subscription. It's an approach — a framework, a philosophy for how to teach reading. Think of it like "jazz" — there's no one jazz song, but there is a clear set of principles that define what jazz is and what it isn't.
Orton-Gillingham is not just for kids with dyslexia. While it was originally developed specifically for students with dyslexia, decades of practice have shown it is highly effective for any struggling reader — whether or not they have a formal diagnosis. The principles work because they're based on how the brain actually learns to read, not just how dyslexic brains are different.
"We use Orton-Gillingham" doesn't mean much on its own. Because OG is a label applied to hundreds of different programs and approaches, it's entirely possible for two tutors to both claim they "use Orton-Gillingham" while delivering completely different quality of instruction. More on this in a moment.
What Orton-Gillingham Actually Is
Orton-Gillingham is a direct, explicit, multisensory, structured, sequential, diagnostic, and cumulative approach to teaching reading, spelling, and writing. Those seven words are the core of it. Let me translate each one.
Direct
Nothing is left to chance or assumed. The teacher explicitly tells the student what they are learning and why. There's no guessing, no "figuring it out" — every concept is directly taught.
Explicit
The rules of the English language are taught openly and clearly. Instead of asking a student to "figure out" a word from context clues, explicit instruction teaches the phonics rule that governs that word — so the student can apply it to every word that follows the same pattern.
Multisensory
This is the heart of OG. Reading is taught using multiple pathways simultaneously — visual (seeing), auditory (hearing), kinesthetic (movement), and tactile (touch). When a child traces a letter in sand while saying its sound aloud while looking at it, three pathways are reinforcing one connection at once. This is what makes OG work for brains that don't form those connections automatically.
Structured
Every lesson follows a predictable, organized format. There's a review component, a new concept component, a practice component. The structure itself helps struggling learners because it removes unpredictability and lets them focus all their cognitive energy on the content.
Sequential
Skills are taught in a specific, carefully designed order — from simplest to most complex. You don't introduce blends before mastering individual phonemes. You don't teach multisyllabic words before single-syllable words are solid. The sequence matters because each skill is the foundation for the next.
Cumulative
Every new lesson reviews and builds on what came before. Nothing is introduced and then abandoned — skills are continuously reinforced and integrated. This is how the brain builds automaticity — the ability to apply a skill without consciously thinking about it.
Diagnostic
The teacher continuously assesses what the student knows and doesn't know, and adjusts instruction accordingly. OG is not a rigid script — it's a responsive approach that meets the student exactly where they are and moves at the pace the student is ready for.
What a Real Orton-Gillingham Session Looks Like
Here's what many parents don't realize — an OG session looks and feels different from typical tutoring. If you've never seen one, here's what to expect.
A typical 45-minute session might look like this:
Minutes 1–10
Warm-Up Review
The tutor shows the student flashcards of previously learned phonogram sounds. The student says each sound aloud — both the letter name and its sound. Then the reverse: the tutor says a sound and the student writes the letter. This builds automaticity through repeated retrieval practice.
Minutes 10–20
New Concept Introduction
The tutor introduces one new concept — say, the "ck" digraph that appears at the end of words after a short vowel (back, kick, lock). The rule is explained explicitly. The student hears it, sees examples, taps out the sounds with their fingers, and writes the pattern. Multiple senses, one concept, fully anchored.
Minutes 20–30
Word Reading and Spelling Practice
The student reads a list of words containing the new pattern — first in isolation, then in context. Then the reverse: the tutor dictates words and the student spells them, saying each sound as they write each letter. This two-way practice (decoding and encoding) is one of the most powerful features of OG.
Minutes 30–40
Connected Text Reading
The student reads a passage or story that uses the patterns they've been learning. The goal is fluency — reading accurately enough that comprehension can happen. The tutor provides immediate, specific feedback on any errors.
Minutes 40–45
Writing / Dictation
The tutor dictates sentences containing the target patterns. The student writes them. This integrates all the skills — decoding, encoding, phonological awareness, letter formation — into a real writing task.
Who Benefits from Orton-Gillingham Instruction?
OG was originally developed for students with dyslexia — and it remains the gold standard intervention for dyslexic learners. But the honest answer is that it benefits a much wider range of students:
Students with dyslexia — This is the primary population OG was designed for. The multisensory, explicit approach directly addresses the phonological processing differences that make reading hard for dyslexic brains.
Students with ADHD — The structured, predictable format of OG sessions reduces cognitive load and provides the routine that ADHD learners need. Short, varied activity blocks maintain engagement better than passive instruction.
Students with auditory or language processing differences — Explicit phonics instruction that doesn't rely on "just sounding it out" is a game changer for these students.
Struggling readers without a diagnosis — Many students fall behind in reading not because of a neurological difference but because they never received adequate phonics instruction. OG fills those gaps systematically.
English language learners — The explicit, systematic approach to the structure of English is highly effective for students learning English as a second language.
The Quality Problem — Why "We Use Orton-Gillingham" Isn't Enough
Here's where I need to be direct with you as a parent, because this is where a lot of families get misled.
Because "Orton-Gillingham" is not a trademarked program, anyone can say they "use OG." A college student with no formal training can take a weekend workshop, buy a set of flashcards, and tell you they offer Orton-Gillingham tutoring. That is not the same as a certified educator with classroom experience delivering proper structured literacy instruction.
The research nuance is important here: some meta-analyses have shown mixed results for "Orton-Gillingham interventions" broadly. The likely reason? Many studies grouped together wildly different quality of implementation under the OG label. When OG principles are implemented with fidelity by trained educators, the results are dramatically different. A 2024 study of OG instruction with dyslexic students showed effect sizes of d=6.55 for reading accuracy — one of the largest effects ever measured in reading research.

Frequently Asked Questions
How long does Orton-Gillingham tutoring take to work?
Results vary depending on the student's starting point, the intensity of sessions, and the consistency of attendance. Many families notice meaningful improvement within 8-12 weeks of consistent, frequent sessions. For students with more significant reading differences, meaningful progress typically requires 1-3 years of sustained intervention. The research is clear that intensity matters — 2-3 sessions per week produces dramatically better outcomes than once a week.
Does my child need a dyslexia diagnosis to benefit from OG tutoring?
No. Orton-Gillingham instruction benefits any struggling reader — with or without a formal diagnosis. The structured, explicit approach works because it teaches reading the way all brains learn best, not just dyslexic ones. If your child is behind in reading, you don't have to wait for a diagnosis to start intervention.
Can Orton-Gillingham be done virtually?
Yes — and in many ways virtual OG tutoring is highly effective. The one-on-one format works seamlessly over video. Digital tools can replicate many of the multisensory techniques used in person. And for many students — particularly those with ADHD or autism — being in their own comfortable home environment actually improves focus and engagement. Education Interventions delivers all sessions virtually.
What's the difference between Orton-Gillingham and Wilson Reading?
Wilson Reading System is an OG-based program — it implements the Orton-Gillingham principles in a highly specific, scripted curriculum. OG itself is the broader approach; Wilson is one structured implementation of it. Both are evidence-based. The key is that whoever delivers the instruction — OG approach or Wilson program — should be properly trained and certified.
How do I know if my child's tutor is really trained in OG?
Ask directly: Where did you receive your Orton-Gillingham or structured literacy training? How many hours of training did you complete? What certification do you hold? A well-trained OG tutor should be able to answer these questions clearly and specifically. If the answer is vague — "I've taken workshops" or "I've read a lot about it" — that's a red flag.
