Orton-Gillingham Homeschool Curriculum: What It Is and How to Use It

If your child is struggling to read — particularly if they have been diagnosed with dyslexia or are showing signs of a phonological processing difficulty — you have almost certainly encountered the term Orton-Gillingham. It appears in nearly every conversation about reading intervention, and for good reason. It is the most researched and most replicated structured literacy approach available. Here is a grounded, practical account of what it is, how to use it at home, and an important note about timing.

What Orton-Gillingham Actually Is

Orton-Gillingham (OG) is not a single curriculum. It is an instructional approach — a method of teaching reading and spelling that is:

Multi-sensory: Every lesson engages visual, auditory, and kinesthetic-tactile pathways simultaneously. A child learning the letter "b" might trace it in sand (tactile), say its sound aloud (auditory), and watch the instructor's mouth form the phoneme (visual) — all in the same activity.

Explicit and direct: Nothing is inferred or discovered. Phoneme-grapheme correspondences (the relationship between sounds and letters) are taught explicitly, one at a time, in a deliberate sequence.

Systematic and sequential: OG builds from the simplest sound-letter relationships to the most complex. A child does not encounter an irregular word pattern until all the prerequisite regular patterns are mastered.

Diagnostic and prescriptive: The instructor assesses what the child knows before each lesson and adjusts the content accordingly. There is no fixed pace; each learner moves through the sequence at their own speed.

This approach was developed by Samuel Orton (a neuropsychiatrist) and Anna Gillingham (an educator) in the 1930s, specifically in response to what Orton called "strephosymbolia" — what we now call dyslexia. The evidence base for structured literacy approaches derived from OG principles is extensive.

OG-Based Programmes Available to Homeschoolers

Because OG is a method rather than a single product, many curricula are described as "OG-based" or "OG-aligned." Some are close to the original approach; others adapt it significantly. Here are the most widely used options for homeschooling families:

All About Reading / All About Spelling

The most popular OG-based programme for homeschoolers. Written specifically for non-specialist parents, it requires no prior training. All About Reading covers reading in four levels (Pre-Reading through Level 4); All About Spelling covers spelling in seven levels. Both use multi-sensory techniques and are carefully sequenced.

Cost: Approximately $80–$120 per level, including teacher guide, student workbook, and tiles. Best for: Parents new to structured literacy who want a complete, scripted programme that tells them exactly what to do each day.

Logic of English

Covers reading, spelling, and handwriting in an integrated OG-aligned framework. More comprehensive in grammar and writing instruction than All About Reading. Available in two main programmes: Foundations (K–2 equivalent) and Essentials (older students and adults).

Cost: Approximately $150–$200 per level. Best for: Families who want a complete language arts programme rather than separate reading and spelling courses.

Barton Reading and Spelling System

One of the most rigorous OG-based programmes available for home use. Barton was specifically designed for students with dyslexia and is widely used by homeschooling families and learning centres. Uses colour-coded tiles and includes explicit parent training videos.

Cost: Approximately $300 per level (10 levels total). More expensive but includes significant parent training. Best for: Children with diagnosed dyslexia or significant reading difficulties who need a structured, intensive approach.

Wilson Reading System

The Wilson system is the most commonly used OG programme in professional and school settings. It is not specifically designed for parent delivery and requires formal Wilson teacher training (a multi-day course). However, some parents do use it, and Wilson offers a parent-teacher collaboration pathway.

Best for: Families with access to a Wilson-certified tutor, or parents who complete Wilson's training.

Spalding (The Writing Road to Reading)

A whole-language arts approach based on Orton's original work. More complex than All About Reading but highly comprehensive. Covers phonograms, spelling, writing, and reading in an integrated sequence.

Best for: Parents with strong language arts backgrounds willing to invest time in learning the method before teaching it.

Free and Low-Cost OG Resources

For families who cannot afford a full commercial programme:

• Nessy: Subscription-based online programme ($100/year) with OG-aligned digital activities. Lower cost than printed programmes.
• Spelfabet (spelfabet.com.au): Australian-based resource with free OG-aligned workbooks available for download.
• Florida Center for Reading Research (fcrr.org): Free, downloadable student activities aligned to structured literacy principles.
• Reading Rockets (readingrockets.org): Free articles, activity guides, and strategy library for parents supporting struggling readers.

A Critical Note About Timing

Orton-Gillingham is intensive, structured, and requires the child's active cooperation. OG lessons are short (20–30 minutes is standard, not an hour) but focused. They require the child to produce, respond, and engage — not passively receive.

For children who have recently left school — particularly those who experienced academic trauma around reading (being shamed for slow progress, reading aloud in class when they were not ready, being held back or labelled) — this is a significant issue. A child whose reading difficulties were handled badly in school can carry real dread around literacy activities. Presenting structured OG lessons in the first weeks after withdrawal risks triggering the same anxiety that made school unbearable.

Many parents of reading-delayed children make this mistake in good faith: they pull their child from school specifically because the school's approach to reading was damaging, then immediately launch into a structured programme at home because they know intervention is important. The child, who has not had time to recover, shuts down. The parent interprets the shutdown as resistance to the method and switches programmes. The switching continues. Years pass.

The recommendation from experienced homeschooling families dealing with literacy challenges: allow a genuine decompression period before beginning structured literacy instruction. During that period, prioritise audiobooks (so the child has access to stories without the anxiety of decoding), reading aloud to the child (removing performance pressure entirely), and any literacy-adjacent activities the child voluntarily engages with (a child who arranges magnetic letters on the fridge is engaging with phonemic awareness without knowing it).

The decompression period does not need to be long — two to four weeks is often sufficient for children whose primary issue is reading difficulty rather than school trauma. For children who experienced genuine academic trauma around reading, a longer recovery is appropriate before formal instruction resumes.

The De-schooling Transition Protocol addresses this specific scenario — how to handle the literacy catch-up pressure during the early transition period without triggering the avoidance that academic trauma creates. Getting this phase right is what allows the OG instruction to actually work when you begin it.

Practical Starting Point

If you are ready to begin an OG programme, All About Reading Level 1 is the most accessible starting point for most homeschooling families. Complete the Level 1 placement test (available free on their website) to determine whether Level 1 or a higher entry level is appropriate. Progress at the pace the child can sustain — the method only works when mastery at each step is genuine before moving forward.
