Orton-Gillingham vs Wilson Reading System: What’s the Difference?

by

Orton-Gillingham vs Wilson is one of the most common questions parents ask when choosing reading help for a child with dyslexia or another language-based learning difference. The short version: Orton-Gillingham is a teaching approach, and the Wilson Reading System is a structured program built on it. This guide explains how they differ, what they share, and how to choose.

Orton-Gillingham vs Wilson: the short answer

Orton-Gillingham is a way of teaching. The Wilson Reading System is a specific program that follows Orton-Gillingham principles. Both are multisensory, systematic and taught one-on-one, but they differ in how fixed the lessons are.

What is Orton-Gillingham?

Orton-Gillingham is a method of teaching designed for children with dyslexia and other language-based learning differences. It was developed in the 1930s by neuropsychiatrist Dr. Samuel T. Orton and educator Anna Gillingham.

The lessons are explicit, systematic and cumulative, and they use sight, sound and touch together. Because it is an approach rather than a fixed curriculum, the tutor chooses what to teach next based on how your child responds. A typical Orton-Gillingham session changes activity every few minutes. It might include reviewing letter sounds, blending and splitting words, and reading short passages. No formal diagnosis is required to begin.

What is the Wilson Reading System?

The Wilson Reading System is a structured literacy program for struggling readers. It teaches decoding, spelling, fluency, vocabulary and comprehension, and it is built on Orton-Gillingham principles.

Wilson follows a carefully sequenced 12-step system that moves from basic sounds to complex words and connected text. Every lesson uses the same structure, and skills learned earlier are reviewed in each session. It is designed for students from grade 2 through adults, and students reading at around a grade 2 level or below can start at any age. Sessions typically run 45 to 90 minutes, and we recommend at least two to three sessions per week.

What do Orton-Gillingham and Wilson have in common?

Quite a lot. Wilson grew out of Orton-Gillingham, so the two share the same foundations:

  • Multisensory teaching. Children learn through sight, sound and touch together.
  • Explicit and systematic lessons. Nothing is left to guesswork; each skill is taught directly and in a planned order.
  • Cumulative practice. New skills build on earlier ones, and old skills are reviewed.
  • One-on-one instruction. The tutor watches your child closely and adjusts as needed.
  • A fit for dyslexia and language-based learning differences. Both are widely used for children who struggle to decode and spell.

Both also fit within what is called a structured literacy approach.

What are the key differences between Orton-Gillingham and Wilson?

  • Approach vs. program. Orton-Gillingham is a set of teaching principles that can be applied in many ways. Wilson is a specific program with its own materials and sequence.
  • Flexibility. Orton-Gillingham lessons are less standardized, so they rely on the tutor's skill in tailoring each lesson. Wilson follows a strict step-by-step sequence.
  • Pace and intensity. Orton-Gillingham lessons change activity every few minutes, with pacing set by your child. Wilson sessions tend to be longer and more intensive, and move through a planned scope and sequence.
  • Materials. Wilson uses a defined set of tools, such as sound cards, letter tiles, controlled text and dictation. Orton-Gillingham tutors choose their materials to suit the child.

Neither is better in every case. The difference is how much flexibility versus structure your child needs.

Which is right for my child: Orton-Gillingham or Wilson?

Orton-Gillingham may be the better fit if:

  • your child is younger and needs early intervention
  • you want lessons shaped closely around how your child responds each session
  • your child has other learning differences alongside reading difficulty, such as ADHD or dysgraphia

Wilson may be the better fit if:

  • your child is in grade 2 or higher (including teens and adults) with persistent reading and spelling difficulty
  • they have not made progress with other approaches
  • you want a clear, step-by-step path with defined stages
  • your family can commit to two to three sessions a week

It is not a contest. The right choice depends on your child's age, current skills and how much structure they need. If you are still unsure, an assessment will answer the question.

Do I need an assessment before choosing?

It is the best first step. A short assessment shows which skills your child has and which are missing, which points to the right program and the right starting point. It is not a diagnosis.

Can Orton-Gillingham and Wilson be done online?

Yes. At The Learnability, both are delivered through live, one-on-one online sessions. Your child works directly with a tutor using interactive digital tools, including digital versions of the sound cards, letter tiles and controlled text used in Wilson lessons. You can sit in from home, with no travel and no waiting room.

Frequently asked questions

Is Wilson better than Orton-Gillingham?

No. Neither is better in every case. Wilson offers a fixed, intensive sequence, while Orton-Gillingham offers more flexibility. The better one is the one that matches your child's age, skills and needs.

Is the Wilson Reading System a type of Orton-Gillingham?

Wilson is based on Orton-Gillingham principles, but it is its own program with a fixed 12-step sequence. Orton-Gillingham tutoring that is not Wilson shapes lessons around the child instead of following a set sequence.

Can my child switch from one to the other?

Often, yes. A tutor can reassess your child's skills and adjust the plan. If you are weighing a switch, contact our team and we will talk it through.

How long will it take?

Both take months of steady work, not weeks. Wilson's 12 steps can take two to three years to complete, depending on where your child starts and how often they have sessions.

Does my child need a diagnosis?

No formal diagnosis is required to begin Orton-Gillingham tutoring. If you also want a diagnosis, a licensed psychologist or neuropsychologist can provide one.
