Orton-Gillingham (OG)

Also known as: Orton-Gillingham approach, Multisensory structured language teaching

Written by Sarah Iqbal, Specialist Teacher / Qualified Teacher of Vision Impairment (QTVI, MA SEN, AMBDA)

Definition

Orton-Gillingham is a structured, multisensory reading and spelling approach developed in 1930s America; in UK dyslexia teaching, its principles are widely used, although a 2021 meta-analysis found no statistically significant effect.

In context for parents

Key checkpoints

  • Orton-Gillingham is an approach, not one programme: teaching is direct, explicit, cumulative and responsive to the learner.
  • Samuel Orton and Anna Gillingham developed the approach in 1930s America; their teaching sequence was systematised in a 1936 manual.
  • Since 2016, the International Dyslexia Association has used “structured literacy” as an umbrella term for teaching descended from Orton-Gillingham.
  • In England, the same underlying principles appear in the DfE requirement for systematic synthetic phonics.
  • Stevens et al. (2021) reviewed 24 studies and found a positive but statistically non-significant effect on foundational reading skills (ES = 0.22, p = .40).
  • The EEF Toolkit reports phonics at +5 months, but evidence for the multisensory element itself is less direct than evidence for systematic, explicit teaching.

In lessons, Orton-Gillingham means making the sound-letter code visible and teachable in small steps. A pupil might hear a sound, say it, trace or write its spelling and then read it in words. Each lesson revisits secure learning before adding the next element. The teacher adjusts the sequence from the pupil’s errors rather than pressing on through a fixed worksheet.

I would not treat “Orton-Gillingham certified” as a UK kitemark. It belongs to an American training system. Here, I look for BDA-accredited teaching qualifications, including AMBDA or ATS, and ask how the teacher assesses, plans and records progress. An Assessment Practising Certificate (APC) relates to assessors, not proof that a particular intervention will work.

Across 24 studies, Stevens et al. (2021) found a positive mean effect on foundational reading, but it was not statistically significant (ES = 0.22, p = .40). Larger, better trials are needed. That does not make OG-style teaching unreasonable; systematic phonics, explicit instruction, cumulative review and decodable practice are well-supported components. Claims that a branded OG package is “proven” go beyond the data.

Schools need not buy an American-labelled product to use those active ingredients. At SEN Support, ask whether teaching is systematic and cumulative, whether the pupil receives it often enough to matter, typically two to five sessions each week, and whether progress is checked. The multisensory activity should serve the reading goal. More tracing is not automatically better teaching.

Where parents ask about this

“Orton-Gillingham” may appear in a tutor's claim even when a UK dyslexia report recommends only structured literacy. That mismatch prompts searches for “Orton-Gillingham UK”, “Orton-Gillingham tutor near me”, “best dyslexia programme UK” and “is Orton-Gillingham evidence based”. Parents also want to know whether multisensory phonics differs from the intervention already offered at SEN Support. The label alone cannot answer the useful questions: Is teaching explicit and cumulative? How frequently will it happen? What will be measured, and when will the plan change if reading does not improve? After reading the assessment and school records, a Beaakon specialist teacher can test the tutor's branded claim against the actual teaching plan and help specify the approach, frequency and progress checks the child needs.
