Orton-Gillingham

About this curriculum

A structured, multisensory, phonics-based approach to teaching reading, spelling, and writing. Originally developed for students with dyslexia, Orton-Gillingham is the foundation behind many homeschool reading programs and is widely used by Christian tutors and learning centers in Arizona.

Orton-Gillingham (OG) is the gold-standard structured-literacy approach for teaching reading, spelling, and writing — especially for students with dyslexia. It's not a boxed curriculum; it's a method delivered one-on-one (or in small groups) by a trained tutor, and it's the single highest-ROI intervention for a struggling reader in Arizona homeschools.

This guide covers what Orton-Gillingham is, how to find an OG tutor in Arizona, how Arizona ESA (Empowerment Scholarship Account) funds cover OG tutoring, and which OG-based curriculums parents can use at home.

What Orton-Gillingham Is (and Isn't)

Orton-Gillingham is an approach, not a workbook. A trained OG tutor sequences instruction from the simplest sound-symbol relationships to the most complex, and every lesson follows a predictable multisensory pattern:

  • See it — the child looks at the letter or pattern
  • Say it — the child says the sound aloud
  • Hear it — the tutor reinforces auditory discrimination
  • Write it — the child traces or writes while saying the sound

Sessions are direct, explicit, cumulative, diagnostic, and multisensory. Nothing is left to guessing or context clues. Every new skill builds on mastered ones, and the tutor adjusts pacing in real time based on the child's response.

This is why OG works where standard classroom reading instruction has failed: it teaches the code of English systematically, and it re-wires the phonological pathway that dyslexic readers struggle to build on their own.

Who Orton-Gillingham Is Best For

  • Children diagnosed with dyslexia or suspected dyslexia
  • Struggling readers in K–5 who are 6+ months behind grade level
  • Poor spellers who read fine but can't spell reliably
  • Kids who confuse b/d, was/saw, or reverse letters past first grade
  • Bright children who avoid reading or fatigue quickly
  • Students who "guessed" their way through early reading and hit a wall in 3rd or 4th grade
  • English-language learners who need explicit phonics

Who Should Consider Something Else

  • Confident readers on grade level with no spelling issues — a standard phonics program is enough
  • Families who need a fully independent, self-paced curriculum — OG requires a tutor or engaged parent
  • Older struggling students with intact decoding but weak comprehension — consider a reading-comprehension specialist instead

How Orton-Gillingham Is Delivered in Arizona

There are three common paths for Arizona homeschool families:

1. Hire an OG-trained tutor (highest ROI)

A certified OG tutor typically meets with your child 2–3 times per week for 45–60 minutes per session, for 1 to 3 years depending on severity. Expect measurable progress in 8 to 12 weeks. This is the fastest, most effective path for dyslexia and moderate-to-severe struggling readers.

2. Use an OG-based curriculum at home

If a trained tutor is out of reach, several curriculums apply OG principles in a parent-led format:

  • All About Reading — the most popular OG-influenced homeschool reading program. Fully scripted, multisensory, and open-and-go.
  • Logic of English — teaches the 30+ phonograms and spelling rules systematically. Great for older struggling readers.
  • Barton Reading & Spelling System — the most explicitly OG-based homeschool program available. Designed for parents with no training. Widely used for dyslexia.
  • Wilson Reading System — used in schools and clinics; requires trained instructor.

At-home curriculums work best for mild-to-moderate struggles or as reinforcement between tutor sessions. For a documented dyslexia diagnosis, a trained tutor plus an OG curriculum is the strongest combination.

3. Combine both

Many Arizona ESA families run an OG-based curriculum at home four days a week and see a certified OG tutor twice a week. Progress accelerates dramatically.

Arizona ESA Eligibility

Yes — Orton-Gillingham tutoring is routinely reimbursed through the Arizona ESA program. This is one of the strongest ESA use cases and one of the reasons Arizona ESA has been transformational for families of struggling readers.

Eligible ESA expenses typically include:

  • 1-on-1 tutoring by a qualified OG practitioner
  • OG-based curriculum materials (All About Reading, Logic of English, Barton, etc.)
  • Educational therapy from providers who use OG or structured literacy
  • Assessments and progress monitoring by qualified providers

Practical flow:

  1. Confirm the tutor accepts ClassWallet Direct Pay or provides invoices for reimbursement.
  2. Keep detailed session notes and invoices (date, duration, service description).
  3. Label receipts clearly (e.g. "Orton-Gillingham reading tutoring — 60 min").
  4. Purchase OG curriculum materials through the ClassWallet marketplace when available.
  5. Save your invoices — reading services are a well-established ESA category.

Religious instruction is not reimbursable under Arizona ESA, but Orton-Gillingham itself is a secular academic method, so eligibility is straightforward. For step-by-step ESA guidance, see our Arizona ESA homeschool guide and how to use ESA funds for curriculum.

Cost of Orton-Gillingham Tutoring in Arizona

Rates vary by city, credential level, and delivery model:

Provider typeTypical Arizona rate
Newly-trained OG tutor$50–$65/hour
Certified OG practitioner$65–$85/hour
Fellow-level / educational therapist$85–$125/hour
Small-group (2–3 students)$30–$50/hour per student

Phoenix, Scottsdale, and North Scottsdale trend to the higher end; East Valley and Tucson are typically mid-range. Many providers offer a sliding scale for ESA families or bundle sessions at a discount.

Daily and Weekly Time Commitment

Plan for:

  • 2–3 tutor sessions per week, 45–60 minutes each
  • 10–20 minutes per day of at-home practice assigned by the tutor
  • Optional 20–30 minutes of an OG-based curriculum on non-tutor days

Consistency matters more than volume. Two short sessions a week done every week for a year beats four sessions a week done sporadically.

What Progress Looks Like

Reasonable milestones for a K–3 struggling reader with a good OG tutor:

  • Weeks 1–4 — child learns the routine and stops resisting reading time
  • Weeks 4–12 — measurable gains in decoding accuracy and letter-sound fluency
  • Months 3–6 — noticeable improvement in spelling and confidence
  • Months 6–12 — often 1+ grade level of growth in decoding
  • Year 2 — reading fluency approaches grade level; comprehension work becomes the focus

Older students (4th grade and up) usually see slower initial gains but similar total growth. The window matters — starting OG in kindergarten or first grade is dramatically easier than starting in fifth.

Advantages

  • The most research-backed approach to teaching reading to dyslexic learners
  • Works across ages, from early elementary through adult
  • Fully covered by Arizona ESA when delivered by a qualified tutor
  • Skills transfer to spelling and writing, not just reading
  • Rebuilds confidence in a child who has decided they "can't read"
  • Compatible with any homeschool style — classical, Charlotte Mason, unit study, eclectic

Drawbacks

  • Requires a trained tutor or highly-committed parent — not a box to open
  • Slower than typical phonics for on-grade-level readers
  • Costs add up without ESA funding
  • Progress isn't linear; some weeks feel flat
  • Tutor quality varies — credentials matter (see below)

How to Choose an Orton-Gillingham Tutor in Arizona

Ask every prospective tutor these questions:

  1. Where were you trained? Look for Academy of Orton-Gillingham Practitioners and Educators (AOGPE), IMSLEC-accredited programs, Barton certification, Wilson certification, or a graduate-level structured literacy program.
  2. What level are you? Common credentials: Associate, Certified, Fellow. Newer tutors can still be effective under supervision.
  3. How do you assess and progress-monitor? Good tutors run a baseline assessment and re-assess every 8–12 weeks.
  4. What does a typical session look like? You should hear something like: warm-up drill, new concept, blending, dictation, controlled reading, sight-word review.
  5. Do you accept ClassWallet or provide ESA invoices? Any experienced Arizona tutor should.
  6. How long do most students stay with you? Expect 1–3 years for a documented dyslexia case.

If a tutor cannot describe their training pathway or their session structure clearly, keep looking.

Frequently Asked Questions

Is Orton-Gillingham the same as a curriculum like All About Reading? No. Orton-Gillingham is a method delivered by a trained tutor. All About Reading, Logic of English, and Barton are curriculums that apply OG principles in a parent-friendly format. Both can help — a trained tutor is usually faster for dyslexia.

Does Arizona ESA cover Orton-Gillingham tutoring? Yes. OG tutoring and OG-based materials are routinely reimbursed through ClassWallet when delivered by qualified providers. Keep clean invoices and session notes.

How much does an Orton-Gillingham tutor cost in Phoenix? Typical Phoenix-area rates run $65–$95 per hour for certified practitioners. Newer tutors and small-group formats are less; educational therapists are more.

How long until we see progress? Most families see measurable decoding gains within 8–12 weeks of consistent 2-to-3-times-weekly sessions.

Is OG only for dyslexia? No. It's ideal for dyslexia, but it also works for any struggling reader, poor speller, or student who missed foundational phonics. Confident on-grade-level readers usually don't need it.

Can I do Orton-Gillingham without a tutor? Partially. Programs like Barton, All About Reading, and Logic of English are designed for parents. For a documented dyslexia diagnosis, a trained tutor is strongly recommended — at least for the first year.

What age is best to start? As early as kindergarten if you see red flags (letter reversals past first grade, family history of dyslexia, resistance to reading, difficulty rhyming). Earlier is easier. Older students still benefit — it's never too late.

Is Orton-Gillingham a Christian curriculum? No. OG is a secular, method-based approach. It works perfectly well in Christian homeschools — many Arizona Christian tutors and learning centers use it. Faith-based content, if any, comes from the tutor or the family, not the method.

How do I know if my child has dyslexia? Look for persistent difficulty decoding, poor spelling despite good speech, letter reversals past 2nd grade, family history, and reading fatigue. A formal evaluation is available through an educational psychologist, some pediatricians, or dyslexia-focused clinics. ESA can cover assessment costs when tied to educational planning.

What comes after Orton-Gillingham? Once a child is decoding fluently at grade level, most families transition to comprehension, fluency, and content-rich curriculum. Options include Sonlight, The Good and the Beautiful, or Charlotte Mason reading. Continue OG-informed spelling instruction (like Logic of English) for another year or two.

Do Arizona microschools and hybrids offer Orton-Gillingham? Some do. A few Arizona microschools and hybrid programs specialize in dyslexia and structured literacy. See the program list below for OG-trained providers on this site.

OG-Based Curriculum Recommendations

  • All About Reading — Best parent-led OG-influenced reading program.
  • Logic of English — Systematic phonograms and spelling rules for older struggling readers.
  • Barton Reading & Spelling — Most explicitly OG-based homeschool program. Designed for dyslexia.
  • Wilson Reading System — Clinic-grade OG-based program; requires trained instructor.

Final Verdict

For Arizona homeschool families with a struggling reader — especially one with dyslexia or a family history of it — Orton-Gillingham is the single most effective intervention available, and Arizona ESA makes it affordable in a way that isn't true in most other states.

Recommendations by family type:

  • Confirmed dyslexia diagnosis. Hire a certified OG tutor immediately. Layer in an OG-based curriculum at home.
  • Suspected dyslexia, no diagnosis yet. Start with a certified OG tutor and pursue an assessment in parallel.
  • Mild reading struggle, no diagnosis. Start with All About Reading or Logic of English. Add a tutor if progress stalls after 12 weeks.
  • Older struggling reader (grades 4+). Certified OG tutor is strongly recommended. Barton is the top at-home option.
  • Arizona ESA family. Use your funds here. Reading is a core academic subject and OG is a well-established, reimbursable use of ESA dollars.
