EBLI vs Orton-Gillingham: which approach is right for your child?

Last updated 2026-07-10

What are EBLI and Orton-Gillingham, exactly?

Orton-Gillingham is a structured, multisensory literacy approach developed in the 1930s by neurologist Samuel Orton and educator Anna Gillingham. It teaches letter-sound relationships in a direct, sequential, cumulative way, engaging sight, sound, and movement together. It's the oldest and most recognized approach for teaching students with dyslexia. Dozens of programs, including Wilson Reading System, Barton Reading, and SPIRE, trace their roots directly to OG principles.

EBLI, short for Evidence-Based Literacy Instruction, was developed by Michigan educator Cindy Sprick and her colleagues starting in the early 2000s. It also teaches phonics directly and systematically, but it organizes the content differently. Instead of the OG convention of treating every phonogram as a discrete unit to drill in isolation, EBLI groups sounds by their most common spellings and teaches students to connect spoken sounds to written words using a specific five-step process. The program argues that most of what students need to know about English spelling fits into a smaller set of core patterns than traditional OG curricula use.

Both approaches sit under the umbrella of structured literacy, a term the International Dyslexia Association defines as instruction that is explicit, systematic, sequential, and diagnostic ^[1]. That shared foundation matters when you're talking to a school or writing an IEP goal, because structured literacy is what reading science supports and what the law increasingly requires. You can read more about the signs that a child might need either approach at signs of dyslexia.

How does EBLI actually differ from Orton-Gillingham in the classroom?

The most visible difference is how spelling patterns get taught. OG programs typically introduce phonograms one at a time in a prescribed sequence, drilling them on cards before applying them to words. A student might spend weeks on a single vowel team before moving on. EBLI does the opposite. From the start, it teaches students that a single sound has multiple possible spellings, and it presents those spellings together. A student learning the long-A sound in EBLI meets 'a,' 'ai,' 'ay,' 'a-e,' and other spellings as a group rather than in separate lessons spread across months.

The multisensory piece looks different too. Classic OG uses sky-writing (tracing letters in the air with big arm movements), sand trays, and tactile letter tiles. EBLI uses a specific finger-tapping system and written practice, and it drops many of the kinesthetic activities OG is known for. Some practitioners argue the OG kinesthetic component helps deeply tactile learners. EBLI's developers argue the extra motor activity eats time without adding measurable benefit.

Pacing is a real difference. A full OG sequence, delivered two or three times a week, usually takes two to three years to complete. EBLI training materials suggest students can move through core content faster, partly because the curriculum is compressed and partly because the grouped-spelling approach cuts the total number of isolated lessons. Independent research on EBLI's actual pace in real classrooms is thinner than OG's, so treat vendor pacing claims with appropriate skepticism.

Teacher training time is another gap. Becoming a certified OG instructor at the Associate level through the Academy of Orton-Gillingham Practitioners and Educators (AOGPE) requires a minimum of 60 hours of classroom instruction, 100 hours of supervised practicum, and a case study ^[2]. EBLI's foundational training is a two-day workshop, with more advanced levels available. That's a much lower barrier to entry, which can be a genuine advantage in a resource-strapped school. It can also mean the person delivering it has less depth.

What does the research say about EBLI vs Orton-Gillingham outcomes?

Here's where honest hedging is necessary. OG has a large body of research behind it, though the quality varies. A 2021 systematic review published in the Journal of Learning Disabilities examined structured literacy interventions and found consistent evidence that multisensory, systematic phonics instruction improves word reading and decoding for students with dyslexia, with OG-derived programs among the most studied ^[3]. The National Reading Panel's 2000 report concluded that systematic phonics instruction produces significant benefits for word reading skills across populations, and that report is the scientific floor both approaches stand on ^[4].

EBLI has fewer independent, peer-reviewed studies. The strongest evidence on EBLI's own website is mostly implementation reports from schools that adopted the program, some showing solid gains in statewide assessment scores and benchmark testing. Those are real data points. They aren't controlled trials, and school-wide reading gains can come from things that have nothing to do with a single program. To be fair, plenty of OG programs also lean on practitioner reports and pre/post comparisons rather than randomized controlled trials.

The What Works Clearinghouse (WWC) at the U.S. Department of Education reviews reading intervention programs against rigorous standards ^[5]. As of 2025, OG-derived programs like Wilson Reading System have WWC reviews. EBLI has not yet received a full WWC review. That's not a disqualifier, but it matters if you're asking a district to fund the intervention, because districts often use WWC ratings to justify what they buy.

The honest summary: OG has more independent evidence, more third-party review, and decades of practitioner data. EBLI has promising school-level outcome data, a smaller evidence base, and a lower training threshold. Nobody has a head-to-head randomized trial comparing them directly. The closest thing is district comparison reports, and those are methodologically messy.

Which approach is better for a child with dyslexia specifically?

For a student with a formal dyslexia identification, OG-based programs have the longest track record and the most legal recognition. The International Dyslexia Association names Orton-Gillingham as one of the foundational instructional frameworks consistent with the science of reading, and many state dyslexia laws point to structured literacy or OG-aligned instruction as the required approach ^[1].

That said, OG is not magic, and implementation quality matters more than the brand name. A poorly trained OG tutor delivering inconsistent lessons will get worse results than a well-trained teacher who understands EBLI deeply. The research on reading intervention keeps landing on the same point: fidelity of implementation, meaning how closely the teacher follows the program's design, is one of the strongest predictors of student outcomes.

If your child has phonological dyslexia, meaning the core deficit is in phoneme awareness and phoneme-grapheme mapping, both approaches should help, because both are phonics-first. If spelling is a particular weakness, some practitioners prefer EBLI's grouped-spelling approach because it tackles the many-to-one relationship between sounds and spellings head-on instead of treating each spelling separately. If your child also has a rapid naming deficit alongside phonological weaknesses (sometimes called double deficit dyslexia), fluency work layered on top of either approach is probably necessary.

One practical factor. If your child is already in an OG-based program and making progress, switching to EBLI is almost certainly not worth the disruption. Continuity in structured literacy instruction matters. The choice-between question comes up most when you're starting fresh or when a current program clearly isn't working.

How do EBLI and Orton-Gillingham compare on cost?

Private OG tutoring is expensive. Rates vary widely by region, but practitioner surveys put certified OG tutors between $75 and $150 per hour, with specialists in high-cost-of-living areas charging more ^[6]. A student getting two sessions a week for a school year at the low end of that range runs roughly $5,400 to $6,000 a year on tutoring alone. OG-based curricula built for parents who teach at home, like Barton Reading and Spelling, cost $299 to $399 per level, and the full sequence spans ten levels.

EBLI's cost structure is different. The basic teacher training (a two-day workshop) runs around $200 to $400 per person through Michigan-based EBLI Inc. School-wide licenses exist for classroom implementation. Parent-delivered EBLI is less common than parent-delivered OG, because fewer home-use materials exist, though some parents do complete the workshop themselves.

If your district uses EBLI school-wide, your child may get it at no extra cost during the school day. If your district uses an OG-based program, same story. The cost comparison matters most when you're privately funding supplemental tutoring. In that case, a qualified OG practitioner is usually more expensive than EBLI support, but the OG practitioner pool is far larger, so you get more options to compare and a better shot at finding someone affordable.

If you're heading into IEP negotiations, know this: IDEA (20 U.S.C. § 1414) requires that a child's IEP include specially designed instruction that meets their unique needs, and it does not name a specific program ^[7]. But if a school agrees to provide a specific evidence-based reading intervention and then quietly swaps in a cheaper option, that can be challenged. The ReadFlare parent advocacy kit has template language for requesting specific instructional methodologies in IEP meetings.

This table reflects typical patterns. Individual programs built on OG vary in length, cost, and structure, so always ask exactly which OG-derived program a school or tutor is using.

What should I ask a school or tutor before choosing one approach?

Start by asking what specific program they use. 'We use Orton-Gillingham' tells you almost nothing. Wilson Reading System, Barton, Fountas and Pinnell (which is not OG at all), and dozens of others get described as 'OG-based' with varying accuracy. Ask for the program name, the publisher, and the instructor's specific credential.

For EBLI, ask which level of training the teacher completed. A two-day workshop is the entry point. More experienced EBLI instructors have completed additional coaching and practicum hours. Ask how many students the teacher has brought through the program and what their outcome data looks like.

Ask how progress gets measured. Both approaches should involve frequent, data-based progress monitoring, ideally with a validated tool like DIBELS 8th Edition or an equivalent curriculum-based measure ^[8]. If a teacher or school can't tell you how they'll know whether your child is making adequate progress, and at what interval they'll reassess, that's a problem no matter which approach they claim to use.

Ask about grouping. OG is traditionally delivered one-on-one or in very small groups of two to three students. EBLI was partly designed to scale into larger classroom settings. Neither is automatically better, but a student with moderate to severe dyslexia who gets EBLI in a group of six probably needs more intensive support than that setting provides.

If your child has already had a dyslexia test or learning disability test, bring that report to the conversation. A good practitioner will want to know where the specific deficits sit before picking an instructional approach.

Can a school be required to provide OG or EBLI under IDEA or a 504 plan?

Under IDEA, a school must provide a Free Appropriate Public Education (FAPE), defined as special education and related services designed to meet the child's unique needs and from which the child can receive educational benefit ^[7]. The statute and its regulations do not mandate any specific reading program by name. What they do require is that the IEP be based on the child's individual needs and that the instruction be reasonably calculated to enable the child to make progress.

The Supreme Court's 2017 decision in Endrew F. v. Douglas County School District raised the FAPE standard. The Court held that to meet IDEA's requirements, an IEP must be 'reasonably calculated to enable a child to make progress appropriate in light of the child's circumstances,' a meaningfully higher bar than the 'de minimis' standard some lower courts had applied ^[9]. This matters for reading programs. If a school's current approach is producing no measurable progress, that's grounds to argue the current IEP is not providing FAPE.

You can request, in writing, that your child's IEP specify instruction that is explicit, systematic, and phonics-based, and you can cite your state's dyslexia law if it names specific instructional characteristics. As of 2024, more than 45 states have passed dyslexia-related education laws, and many require structured literacy instruction and evidence-based approaches, though the specifics vary dramatically by state ^[10].

A 504 plan under Section 504 of the Rehabilitation Act can require accommodations, but it typically does not mandate a specific instructional methodology the way an IEP's specially designed instruction component can. If your child needs a specific reading intervention, push for an IEP evaluation rather than settling for a 504 alone.

Are there situations where neither EBLI nor OG is the best first choice?

Yes. If a child is in kindergarten or early first grade and hasn't been assessed for reading difficulties yet, the first step is high-quality, universal phonics instruction in the classroom, not a specialized intervention. The Simple View of Reading and research from the National Reading Panel both support starting with strong core instruction before adding intensive one-on-one work ^[4]. Good core instruction means a phonics-based curriculum delivered with fidelity, which many general education classrooms now provide through programs like Amplify CKLA or SPIRE.

If a child has already had two to three years of OG or EBLI-based instruction with documented poor progress, it's worth asking whether an additional evaluation is needed. Some children have co-occurring language disorders, auditory processing difficulties, or vision problems that phonics instruction alone won't touch. A speech-language pathologist's evaluation or a developmental vision exam might add useful information before doubling down on either approach.

For children who struggle heavily with reading comprehension after their decoding has improved, neither EBLI nor OG is the right primary tool. Both are decoding-first interventions. Comprehension difficulties at that stage need different approaches, including vocabulary instruction, background knowledge building, and explicit strategy teaching.

If spelling is the dominant concern and your child reads adequately but spells very poorly, some practitioners prefer EBLI's emphasis on sound-to-spelling connections as a primary tool. That's a reasonable clinical hypothesis, though it hasn't been tested head-to-head against OG spelling components in a controlled study.

How do I actually find a qualified EBLI or OG practitioner?

For Orton-Gillingham, the Academy of Orton-Gillingham Practitioners and Educators (AOGPE) keeps a practitioner directory on its website where you can search by location and certification level ^[2]. The International Dyslexia Association also has a provider directory. Look for practitioners certified at the Associate level or above. 'Trained in OG' without a credential means very little, because training quality varies enormously.

For EBLI, practitioners are found mainly through the EBLI Inc. website, which lists certified trainers. The pool is smaller and more concentrated in the Midwest, though the program has expanded nationally. Online delivery is available and works reasonably well for older students.

When you interview anyone, ask them to explain exactly how they'd structure a lesson for a student at your child's current level. A qualified practitioner should walk you through the lesson structure, explain how they assess progress, and describe what they'd do if your child plateaus. Vague answers are a warning sign.

The ReadFlare reading toolkit includes a printable set of interview questions for evaluating reading tutors, and it works for either OG or EBLI providers. Families who want to monitor progress at home while a specialist handles instruction can also use sight word flashcards and decodable reading practice to reinforce whatever approach the specialist is using.

What do parents of kids in these programs actually report?

Let me be clear: I'm not citing testimonials here, because anecdotal reports point in any direction you want them to. What I can say is that published case studies and practitioner reports across both programs share a few common threads.

Parents whose children received OG from a certified specialist most often report that progress was slow in the first few months and then picked up, which lines up with research showing that OG builds automaticity gradually. The programs are intensive and depend on consistent attendance. Families report that gaps of more than a week or two set students back noticeably.

Parents whose children were in EBLI-based school programs most often note that spelling improvements showed up earlier than they expected, and that teachers were enthusiastic because the training was accessible. The critique that surfaces more in EBLI parent reports is inconsistency. Because teacher training is shorter, quality varies more across classrooms in the same school.

Both programs need parental involvement to reinforce learning at home. Students who read aloud at home for fifteen to twenty minutes a day show faster progress in both frameworks, consistent with research on reading fluency development. A simple decodable-reader routine costs nothing and matters more than the program brand.

Frequently asked questions

Is EBLI approved for students with dyslexia?

EBLI is consistent with structured literacy principles recognized by the International Dyslexia Association, so it's an appropriate approach for students with dyslexia. It has not received a full What Works Clearinghouse review as of 2025, and it isn't named in state dyslexia laws as often as OG-derived programs are. Whether it meets your state's specific requirements depends on your state's law.

Can a parent learn EBLI or OG to teach their own child?

Yes to both, but the effort differs. The EBLI two-day workshop is genuinely accessible to motivated parents and costs roughly $200 to $400. Learning OG well enough to deliver it effectively takes significantly more time. Barton Reading and Spelling was built for parents and tutors without formal certification, and parents do use it successfully. Expect to practice the lessons yourself before teaching your child.

How long does OG tutoring take to show results?

Most children receiving two to three OG sessions a week begin showing measurable decoding improvements within three to six months. Full remediation for a student with moderate dyslexia typically takes two to three years. Progress monitoring every six to eight weeks with a validated tool helps you tell whether the pace is adequate or whether adjustments are needed.

Is EBLI used in public schools?

Yes. EBLI has been adopted school-wide in a number of public districts, primarily in Michigan and the Midwest, and increasingly in other states. It's designed to scale across classrooms, which makes it attractive to districts looking for a single approach they can train all teachers in quickly. Adoption outside the Midwest is still growing.

Does insurance cover OG or EBLI tutoring?

Private health insurance almost never covers reading tutoring directly. Some families use FSA (flexible spending account) funds for tutoring if a physician prescribes it as medically necessary, but this is not guaranteed and depends on your FSA plan. If tutoring is written into an IEP as a related service or extended school year service, the district covers it. Talk to your benefits administrator and your child's IEP team directly.

What is the difference between OG and Wilson Reading System?

Wilson Reading System is an OG-derived program. It's built on OG principles but comes as a fully packaged curriculum with its own materials, lesson scripts, and training requirements. Pure OG as taught by a certified practitioner is more flexible and customized. Wilson is often easier to implement with fidelity in schools because of its structured format, but both count as structured literacy approaches.

Can a school refuse to use OG if a parent requests it?

Yes. IDEA does not require schools to use any specific program by name. Schools must provide a free appropriate public education, but they have discretion in how they deliver it. Your strongest move is to document that the current approach isn't producing adequate progress, then request an independent educational evaluation and present peer-reviewed evidence for the alternative at the IEP meeting.

Are there any studies directly comparing EBLI and OG head to head?

No published, peer-reviewed randomized controlled trial has directly compared EBLI and Orton-Gillingham as of 2025. The evidence base is separate bodies of research on each approach, plus district implementation reports. Both camps have pre/post outcome data. Neither has a head-to-head comparison that meets rigorous research standards. Anyone claiming one definitively beats the other is overstating the evidence.

My child's school uses balanced literacy, not OG or EBLI. What can I do?

Balanced literacy is not a structured literacy approach and lacks the systematic phonics instruction the science of reading supports. You can request, in writing, a special education evaluation if your child is struggling. If your child has an IEP, you can request that the specially designed instruction include explicit, systematic phonics and cite your state's dyslexia law if it applies. Document everything in writing.

Does OG work for kids without dyslexia who are just behind in reading?

Yes. OG and structured literacy approaches work for most struggling readers, not only those with a dyslexia diagnosis. Reading research shows that systematic phonics instruction benefits virtually all early readers, and struggling readers in general education show gains from OG-based interventions. A diagnosis is not required to access or benefit from the approach.

Is EBLI the same as the science of reading?

No. EBLI is consistent with the science of reading in that it's phonics-based, explicit, and systematic. The 'science of reading' is a broader body of evidence covering phonemic awareness, phonics, fluency, vocabulary, and comprehension. EBLI is one instructional program aligned to part of that evidence base, not the whole of it.

How do I know if my child needs OG or EBLI versus just more phonics practice?

If your child is more than one grade level behind in reading after a full year of phonics-based core instruction, an evaluation is warranted rather than just piling on more practice. A formal assessment can pinpoint the specific deficit, whether phonemic awareness, decoding, fluency, or something else, and that should guide the intervention choice. See the dyslexia test article for what a good evaluation includes.
