Orton-Gillingham, Explained

Orton-Gillingham is the approach most often recommended for children with dyslexia, and it’s the one term parents encounter again and again once reading starts going badly. It was developed in the 1930s by a neurologist and an educator working with children who could not learn to read by ordinary classroom methods.

Eight programs on this site use it, across reading and spelling.

What makes it different

It is structured and cumulative. Every concept is introduced in a fixed order, each one building on the last, with nothing assumed. A child never meets a word containing a sound the program hasn’t already taught.

It is explicit. Nothing’s left for the child to infer. If a letter combination makes a particular sound, the program says so directly and practices it.

It is multisensory. A child sees the letter, says the sound, and traces or moves a tile at the same time. The reasoning is that engaging several channels at once builds a stronger memory than looking alone.

It is diagnostic. The teacher watches for what the child hasn’t mastered and stays there rather than moving with a schedule. That’s why Orton-Gillingham programs are almost always taught one to one.

What a lesson looks like

Short and highly routine. A typical session reviews previously taught sounds with cards, introduces one new concept, practices it in isolation, then in words, then in a sentence or a short passage. Twenty minutes is common.

The routine is the point. Owners consistently report that the sameness of the lesson structure is what lets a struggling child relax into it, because nothing unexpected is coming.

Who it tends to suit

Children with dyslexia, or those showing the signs: reading that stays effortful long after peers have become fluent, guessing at words from the first letter, spelling the same word three different ways on one page, or strong comprehension when listening paired with weak reading.

It also suits children with no diagnosis at all who simply need more structure than a typical program offers. The approach isn’t harmful to a child who’d have learned to read anyway. It’s slower, and a child who picks up reading easily may find the pace tedious.

The real cost is parent time. Seven of the eight programs here score 4 or 5 on parent involvement. This method is delivered by a person sitting with a child.

Where it shows up on this site

Reading has five: All About Reading, Explode the Code, First Start Reading, Logic of English Foundations, and PRIDE Reading Program.

Three of those carry the Dyslexia tag, meaning owners of children with dyslexia specifically report success: All About Reading, Logic of English Foundations, and PRIDE Reading Program. PRIDE spans K-8, which matters because most phonics programs stop around grade 4 and leave older struggling readers with nothing age-appropriate.

Spelling has three: All About Spelling, Apples and Pears Spelling, and Sequential Spelling. Spelling is where Orton-Gillingham often matters most, because a child can memorize their way through reading a word and still be unable to produce it.

Explode the Code is the outlier in the group. It scores 2 on parent involvement and works as a supplement rather than a spine, so it functions as extra practice alongside a main program rather than as the program itself.

What it is not

Orton-Gillingham is an approach rather than a branded product. No single company owns it, which is why programs using it vary in cost, materials, and how closely they follow the original structure. A program describing itself as Orton-Gillingham based may be looser than one describing itself as Orton-Gillingham.

It’s also not the same as synthetic phonics, though the two overlap heavily and five of the eight carry both labels. Synthetic phonics describes what is taught, sounds blended into words. Orton-Gillingham describes how, through multisensory, diagnostic, one-to-one instruction. A program can be synthetic phonics without being multisensory or diagnostic.

Finally, a curriculum isn’t a diagnosis. If reading is going badly enough that you’re researching this, an evaluation tells you things no program can.
