What Is an Orton-Gillingham Tutor — and Does My Child Need One?

What is Orton-Gillingham, exactly?

Orton-Gillingham is an approach to reading instruction, not a single program or curriculum. It was developed in the 1930s by Samuel Orton, a neurologist, and Anna Gillingham, an educator, and has been refined and expanded significantly since then.

The core principles: instruction is structured (skills are taught in a deliberate order, from simple to complex), sequential (new concepts build on mastered ones), and multisensory (students learn through sight, sound, and touch simultaneously — tracing a letter while saying its sound, for example). Nothing is assumed to be picked up naturally. Every skill is taught directly.

Because O-G is a method rather than a branded program, many reading curricula are described as "Orton-Gillingham based" — meaning they're built on its principles even if they go by a different name. Wilson Reading System, Barton Reading and Spelling, and RAVE-O are among the well-known programs in this family. The International Dyslexia Association (IDA) maintains a list of programs that meet its structured literacy standards, which is a useful reference when evaluating options.

How is an O-G tutoring session structured?

A trained O-G tutor typically works one-on-one with a child, usually in sessions of 45 minutes to an hour. Each session follows a consistent structure: review of previously learned material, introduction of a new concept, guided practice, and application. The pacing is set by the child — new concepts aren't introduced until earlier ones are solid.

This individual pacing is a meaningful distinction from classroom instruction, where the curriculum moves on a fixed schedule regardless of whether every child has consolidated each skill.

Does my child need an Orton-Gillingham tutor?

It depends on two things: what the school is already providing, and whether it's working.

If your child has a reading support plan at school that uses a structured literacy approach — and your child is making measurable progress — additional private tutoring may not be necessary right now. Ask the school specifically what program they use and how often your child receives it. Vague answers ("we do small group reading support") are worth pressing on.

If school support is limited, inconsistent, or not producing visible results after several months, a private O-G tutor can fill that gap. This is especially relevant if your child is on a 504 Plan (which provides accommodations but not specialized instruction) rather than an IEP (Individualized Education Program, which can require the school to provide structured reading instruction directly). Understanding which plan fits your child's needs matters here.

Private tutoring is also worth considering if your child is behind enough that they need more intensive practice than a school setting can realistically provide — more sessions per week, longer sessions, or faster pacing.

What should I look for in an O-G tutor?

Training and supervised practice hours are what distinguish a qualified O-G tutor from someone who took a weekend workshop and calls themselves O-G trained. When you talk to a potential tutor, ask directly:

• Where did you complete your O-G training, and how many hours did it involve?
• Did your training include supervised, mentored practice with students?
• Do you hold a credential from the IDA or IMSLEC (International Multisensory Structured Language Education Council — the accrediting body for structured literacy training programs)?

IDA Associate or Certified membership and IMSLEC-accredited credentials are meaningful signals of quality. They're not the only path to a good tutor, but they give you something concrete to evaluate.

Also ask how they measure progress. A good O-G tutor tracks data across sessions and adjusts pacing based on what the data shows — not just on general impressions of how a child is doing.

What to do next

1. Find out what your child's school is already providing. Ask for the name of the program, how often your child receives it, and how progress is being measured. Get the answer in writing.

2. Check whether your child's current plan includes specialized instruction. If they have a 504 Plan rather than an IEP, the school may not be required to provide structured reading instruction at all — accommodations and instruction are different things.

3. Ask your school's reading specialist for a referral. Many specialists know qualified local tutors and can point you toward someone whose approach will align with what's happening in the classroom.

4. Interview more than one tutor before committing. Ask about training, credentials, how they structure sessions, and how they communicate progress to families. The relationship matters as much as the credentials.

5. Factor in frequency. Research from the IDA suggests that structured literacy instruction is most effective when delivered at least three to four times per week. A tutor you can see once a week may help, but it's worth being realistic about what that pace can accomplish.
