OG vs. Barton: A Parent's Plain-Language Guide

A parent walks into a dyslexia evaluation and the specialist says: "She'll need OG." The parent goes home, searches for "OG programs," and lands on a page with a dozen names. Barton. Wilson. All About Spelling. SPIRE. Logic of English. They all say "Orton-Gillingham based." They're all priced differently. Some require a certified tutor. Some ship in cardboard boxes.

None of them explain why there are twelve options when the specialist just said two letters.

Here's what the specialist meant.

What "OG" actually is (and why you can't just order it)

Orton-Gillingham isn't a box you order. It's a framework, developed by neurologist Samuel Orton and educator Anna Gillingham in the 1930s and still considered foundational by the International Dyslexia Association.

The OG approach has four defining characteristics:

Multisensory. Lessons engage the eye, ear, and hand at once. A child sees a word, says it aloud, and writes it. Three pathways to the brain, not one.
Explicit. Spelling rules are taught directly. Nothing is left for the child to work out on their own.
Systematic and sequential. Skills build in a deliberate order, simple to complex.
Diagnostic. The teacher watches what the child does and adjusts based on what they observe.

These four principles are what make OG effective for kids with dyslexia. They're also what every program on that search results page has in common.

When a specialist recommends "OG tutoring," they usually mean sessions with a practitioner certified in an OG-based approach — Wilson, RAVE-O, or direct Orton-Gillingham training. That practitioner adapts lessons on the fly. They're not working from a script. It's the most individualized version of OG instruction, and typically the most expensive: certified tutors often run $80–150/hour, and a child with significant dyslexia may need two to three sessions a week for years.

For families who can't access or afford that, OG-based programs like Barton are how parents deliver the same instruction themselves.

What Barton is

Barton Reading and Spelling System is a specific OG-based curriculum designed for parents and tutors to use at home, no background in reading instruction required. Susan Barton built it because she wanted a program that didn't require a master's degree to deliver.

Barton comes in ten levels, each covering a set of phonics patterns and spelling rules in sequence. Lessons are scripted. The parent reads from a teacher guide; the child works with letter tiles, sound cards, and structured reading passages. Sessions typically run 20–30 minutes, one-on-one.

What makes Barton useful for homeschool families:

No tutor certification required
Clear, scripted lessons the parent reads aloud
Stronger emphasis on spelling than most OG-based programs
Designed for the kitchen table, not a specialist's office

It's also a multi-year commitment. Many families complete three to five levels before seeing the spelling gap close, and each level carries a significant price tag.

What they share

Whether you're running Barton at home or sitting with a certified Wilson practitioner, the core mechanism is the same: explicit instruction in how English spelling works, delivered multisensorially, in a structured sequence.

Both teach:

Phoneme-grapheme connections (which letters map to which sounds, and why)
Spelling rules and patterns (why "ck" follows a short vowel, why "tion" sounds like "shun")
High-frequency irregular words (the ones that break the rules)
Reading and writing together, not one without the other

This is what the IDA calls Structured Literacy: an umbrella term for OG and all programs built on its principles. Barton qualifies. So does Wilson, All About Spelling, Logic of English, and others.

The label "OG-based" isn't a quality rating. It's a lineage marker. It means the program teaches the same foundational things in roughly the same way the original approach intended. Choosing between them comes down to delivery format, pacing, cost, and whether you need the parent to run it or a trained specialist. For a breakdown of how the phonics instruction layer connects to everything that comes after, The Four Layers of Spelling covers where OG-style instruction ends and where the practice work begins.

Where Spellexi fits

OG instruction, whether through Barton or a tutor, handles the teaching. It gives kids the blueprint for how English spelling works.

The gap most families hit is what comes after. A child can work through a Barton level, understand the rule, and still miss the same words in their writing a week later. That's not a failure of Barton or the tutor. It's a retention gap: the space between "I learned this" and "I just know this without thinking." Retrieval practice is the mechanism that closes it — and it's the part most structured programs leave to the parent to figure out.

Spellexi is the practice layer for that gap. You read words aloud. Your child writes them on paper. A photo grades the work. The app schedules each word to come back at the right interval until it's locked in. No prep, no spreadsheet, no guesswork about what to review next.

Spellexi also includes OG-style scaffolding for words that keep coming back wrong. When a word isn't sticking, the app offers a short pre-practice card: the parent reads the spelling pattern aloud, parent and child say the word together, then the child traces it on the table with one finger. Visual, auditory, kinesthetic — the same multisensory encoding OG practitioners use in session. That supported attempt is excluded from mastery math, so only unaided recall moves the word forward. It's the I do / we do / you do gradual release model, applied to the exact words this specific child keeps missing. For more on what scaffolding looks like in practice, What Is Scaffolding? covers the concept in plain language.

Spellexi isn't a Barton replacement and it isn't an OG curriculum. It's what runs alongside either of them, or what keeps words locked in after a family finishes a structured program and moves on. For a side-by-side look at how Spellexi sits next to another OG-based program, the All About Spelling vs. Spellexi comparison covers the same complementary relationship.
