IMSE Orton-Gillingham curriculum: what parents need to know

Last updated 2026-07-10

What is IMSE and how does it relate to Orton-Gillingham?

IMSE stands for the Institute for Multi-Sensory Education, a private teacher-training company founded in 1995 and headquartered in Michigan. It doesn't publish a standalone student workbook the way a basal reading series does. Instead, it trains classroom teachers, reading specialists, and interventionists to deliver structured literacy instruction using the Orton-Gillingham (OG) approach.

Orton-Gillingham itself isn't a single curriculum or product. It's a teaching approach developed in the 1930s by neurologist Samuel T. Orton and educator Anna Gillingham. The core idea is that reading, spelling, and writing should be taught explicitly and in a set sequence, using multiple senses at once, so students see, say, hear, and write letters and sounds together. ^[1] IMSE adapts those principles into a trainable method that schools can deliver inside a standard classroom.

The Orton-Gillingham Academy (the professional credentialing body) describes OG as "a direct, explicit, multi-sensory, structured, sequential, diagnostic, and prescriptive way to teach literacy." ^[1] IMSE's training is designed to be consistent with those principles, though IMSE's own certification is separate from the Academy's Fellow or Certified Associate credentials.

One thing to understand upfront: IMSE is not free. There is no IMSE "Orton-Gillingham curriculum free" download for teachers or parents. The value is in the training, the scope and sequence guides, and the ongoing coaching, all of which cost money. Free OG-aligned resources do exist elsewhere, and we'll cover those later.

What does IMSE's training program actually cover?

IMSE offers several training tiers, each building on the last. The entry point is the Overview course, a shorter introduction to OG principles. The main credential most schools pursue is the Orton-Gillingham Practitioner course, typically delivered over five days (in-person or virtual) followed by a practicum period. There's also an Advanced level for teachers who work with more complex learners.

The content covers phonemic awareness, phonics (including phoneme-grapheme correspondences across six syllable types), fluency, vocabulary, and handwriting. Structured literacy researchers would recognize these as the components behind the "Simple View of Reading," the framework that says reading comprehension equals decoding ability multiplied by language comprehension. ^[2] IMSE's scope and sequence works through consonants, short vowels, blends, digraphs, vowel teams, r-controlled vowels, and multisyllabic word patterns in a fixed, deliberate order so no student skips a foundational skill.

One feature that sets IMSE apart from a generic phonics course is its emphasis on diagnostic teaching. Teachers learn to give ongoing informal assessments and adjust the lesson based on what the student did wrong that day. That responsive feedback loop is one reason OG-based instruction shows stronger results for students with dyslexia than scripted phonics programs that don't adjust to the individual. ^[3]

IMSE also trains teachers in Socratic questioning for phonics review, where the teacher asks "What does this say?" and "What is the rule?" rather than just handing over the answer. It's slower. It works better for retention.

How much does IMSE training cost, and who pays for it?

IMSE publishes pricing on its website. As of early 2025, the five-day Orton-Gillingham Practitioner training runs about $1,295 to $1,595 per teacher for the live course, with site-license discounts available when a district brings IMSE trainers in-house. The Overview course is shorter and less expensive, typically in the $400 to $600 range. Advanced training and ongoing coaching add cost. ^[4]

In most cases, the school district pays. Federal Title I funds and IDEA Part B grants (which flow to states and then to local education agencies) can legally be spent on evidence-based professional development. ^[5] If your district says it "can't afford" structured literacy training, that's a budget-priority argument, not a legal reality. IDEA requires a free appropriate public education (FAPE) for eligible students, and courts have found that FAPE can be denied when a school fails to provide instruction that addresses a student's specific disability, including dyslexia. ^[5]

Parents asking whether the district will pay for IMSE training as part of an IEP should frame the request around the student's needs, not the product. The IEP team must agree on specially designed instruction; the method (OG-based, IMSE-trained teacher) is a means to deliver that instruction. Some districts will write "structured literacy using an Orton-Gillingham approach" directly into the IEP's service description. That language gives you a foothold if the school later assigns an untrained teacher.

IMSE Training Level	Typical Duration	Approximate Cost (per teacher)
Overview	1-2 days	$400-$600
OG Practitioner	5 days + practicum	$1,295-$1,595
Advanced	Additional coursework	$800-$1,200+
District site license	Varies	Negotiated

These figures come from IMSE's published schedule and may change. Always confirm current pricing at imse.com before citing them in a meeting.

Is IMSE considered evidence-based? What does the research say?

This is where honest hedging matters. IMSE as a company has not published its own randomized controlled trial showing that IMSE-trained teachers produce better outcomes than non-IMSE-trained teachers. That kind of study is expensive and rare in teacher-training research generally.

What does exist is strong evidence for the underlying OG approach and for structured literacy broadly. A 2019 meta-analysis published in the Journal of Learning Disabilities examined 21 OG-based intervention studies and found meaningful positive effects on word reading and spelling for students with dyslexia, with effect sizes ranging from 0.40 to 0.76 depending on the outcome measure. ^[3] That's a moderate-to-large effect in education research terms.

The International Dyslexia Association (IDA) reviewed IMSE's curriculum materials and, as of its most recent review cycle, classified IMSE as meeting its Knowledge and Practice Standards for educators who teach reading. ^[6] That's not the same as a clinical trial. It is a meaningful third-party signal.

The What Works Clearinghouse (WWC) at the U.S. Department of Education has reviewed OG-based programs individually rather than reviewing IMSE directly. Programs like Wilson Reading System and Barton, which share OG roots, have received "potentially positive" ratings on the WWC. IMSE's approach is methodologically similar, though the WWC has not produced an IMSE-specific review. ^[7]

Bottom line: the science underneath IMSE is solid. The company-specific evidence gap is real but not unusual for professional development products. If a school or advocate tells you IMSE is "not evidence-based," ask them which structured literacy approach they'd substitute and what evidence backs that one instead.

How does IMSE compare to other Orton-Gillingham programs?

OG-based programs range from full curriculum systems to teacher-training models like IMSE. Here's how the main ones stack up.

Wilson Reading System is a fully scripted 12-step curriculum with student workbooks, cards, and sound cards. Teachers need Wilson certification, which takes roughly 40 to 50 hours. Wilson targets students in grades 2 and up who have already failed other interventions. It costs more per student than IMSE but runs more hands-off for the teacher once trained. ^[8]

Barton Reading and Spelling is designed so that a trained tutor or parent can deliver it, which makes it popular for home use. It costs $299 to $399 per level and there are 10 levels. Parents can teach it without a teaching credential. That flexibility sets it apart from IMSE, which is strictly a school-based professional development model.

Lindamood-Bell uses related but distinct processes (LiPS and Seeing Stars programs) rather than traditional OG phoneme-grapheme correspondence work. It's clinically intensive and expensive, often $100 or more per hour for center-based delivery.

RAVE-O (Retrieval, Automaticity, Vocabulary, Engagement with Language, Orthography) is a research-developed program out of Tufts University that combines fluency and vocabulary more explicitly than classic OG. It's used more in research settings than in typical schools.

IMSE sits in the middle. It costs less than Wilson or Lindamood-Bell per student, it's designed for classroom teachers rather than specialists, and it's built to scale across an entire school or district. If your school is trying to do whole-classroom structured literacy rather than pull-out intervention for five kids, IMSE is a reasonable choice. If your child has severe dyslexia and needs intensive one-on-one remediation, something like Wilson or a Lindamood-Bell program may fit better.

Check the signs of dyslexia in your child first, so you understand how severe the reading difficulty actually is before pushing for a specific program.

Can parents use IMSE curriculum at home?

No, not directly. IMSE does not sell a parent-facing home curriculum. Its materials, lesson plan templates, and sound card decks are sold to trained educators who have completed IMSE coursework. You won't find a boxed IMSE kit on Amazon.

That said, parents have options. Barton Reading and Spelling (mentioned above) is built for home delivery and is the most practical OG-based option for parents without a teaching background. All About Reading and All About Spelling are OG-aligned programs marketed directly to homeschoolers and run $40 to $150 per level. Neither requires prior training.

Free OG-aligned resources exist too, though they're piecemeal. Phonics cards, scope-and-sequence charts, and decodable text lists are available from the Florida Center for Reading Research (fcrr.org) and ReadWorks. The IDA also maintains a free resource library. None of these replicate the full IMSE experience, but they can supplement what a trained teacher does at school.

If your child has an IEP, you can ask that the school send home OG-aligned decodable readers that match the teacher's current scope and sequence point. That continuity between school and home is worth requesting in writing. The ReadFlare parent advocacy kit includes a template for exactly that kind of supplemental request, which keeps home practice in sync with whatever method the school is using.

For parents starting the screening process, a dyslexia test or a learning disability test through the school or a private evaluator can clarify whether OG-based instruction is the right fit or whether something else is driving the reading difficulty.

How do you know if a teacher is actually IMSE-trained?

Ask directly, in writing. You have the right to ask the school what training your child's reading teacher or interventionist has received. A genuine IMSE Practitioner holds a certificate from IMSE after completing both the coursework and the supervised practicum. Some teachers take only the Overview training and stop there. That's a shorter exposure that doesn't fully qualify them to deliver OG-based intervention on their own.

IMSE maintains a directory of certified practitioners on its website at imse.com. You can search by zip code. If the school tells you a teacher is OG-trained but she doesn't appear in that directory, ask whether she holds certification from a different OG organization (Wilson, the Academy of Orton-Gillingham Practitioners and Educators, Barton, and so on). Multiple legitimate credentials exist.

During IEP meetings, you can request that the service description specify the training level of the person delivering the intervention. Language like "instruction delivered by a teacher trained in Orton-Gillingham methodology to the Practitioner level" is specific enough to hold a school accountable. Vague language like "structured literacy support" can be filled by anyone.

If you suspect your child isn't making progress because the instruction isn't being delivered correctly, you have the right to request an Independent Educational Evaluation (IEE) at public expense under IDEA Section 300.502. ^[5] An outside reading specialist can observe instruction and tell you whether what's happening in the room matches what OG is supposed to look like.

What do IEP and 504 rights have to do with Orton-Gillingham?

The connection is direct. IDEA requires schools to provide eligible students with a free appropriate public education using specially designed instruction. ^[5] The law doesn't name Orton-Gillingham specifically, but several states now do. As of 2024, more than 40 states have passed dyslexia-specific laws, and many of them require schools to use "structured literacy," "phonics-based," or explicitly "Orton-Gillingham-based" methods for students identified with dyslexia. ^[9]

The Every Student Succeeds Act (ESSA) of 2015 added language encouraging states to use evidence-based reading interventions, pointing to the National Reading Panel's findings on phonemic awareness, phonics, fluency, vocabulary, and comprehension. ^[10] OG-based instruction addresses all five of those components, which is why advocates use it as a benchmark when arguing that a school's current approach isn't working.

For 504 plans (which cover students who don't qualify for special education but have a disability that substantially limits a major life activity like reading), OG-based instruction can be written as an accommodation or modification. The Rehabilitation Act's Section 504 requires comparable access to education; if a student with dyslexia can't access the curriculum without OG-based support, that support becomes part of the plan. ^[11]

A few practical notes. "Orton-Gillingham" written into an IEP gives you more enforcement power than "structured literacy," which is broader. Some districts resist program-specific language because it limits their flexibility. Either way, make sure the IEP states how many minutes per week of specialized reading instruction the child receives, who delivers it, and at what training level.

For parents new to the IEP process, understanding learning disabilities broadly and the specific profile of phonological dyslexia can help you make the case that structured, sequential phonics instruction is necessary rather than optional.

What states require Orton-Gillingham or structured literacy in schools?

This area changes quickly. As of mid-2025, states with laws that explicitly require structured literacy or OG-based methods for students with dyslexia or reading difficulties include Texas (HB 3928), Arkansas, Mississippi, Louisiana, Florida, North Carolina, and Ohio. Mississippi's mandate is the most studied: the state adopted structured literacy statewide in 2013 and saw its National Assessment of Educational Progress (NAEP) fourth-grade reading rank improve from 49th to 21st in the nation over roughly ten years. ^[9]

Some states go further and name specific screeners. Texas requires all K-3 students to be screened for dyslexia risk using a tool from the state's approved list, and schools must provide intervention using a program consistent with OG principles for identified students. ^[9]

Even in states without explicit mandates, IDEA and ESSA create pressure toward evidence-based reading instruction. If your state doesn't have a dyslexia law, you're working with federal floor rights, which are real but harder to enforce specifically around method.

The National Center on Improving Literacy (literacy.uconn.edu) maintains state-by-state policy summaries and is a reliable source for checking your state's current requirements. ^[12] Don't rely on your school district's summary of what the law requires. Look it up yourself, or work with a parent advocate who knows your state's statutes.

Knowing your state's law is one of the most practical things you can do before walking into an IEP meeting about reading intervention. It changes the conversation from "we recommend this approach" to "the law requires this approach."

Are there free Orton-Gillingham curriculum resources parents can actually use?

Yes, though none replicate a full IMSE-trained teacher. Here's what's genuinely useful and free.

The Florida Center for Reading Research (fcrr.org) publishes free, research-based student center activities for K-5 that align with structured literacy principles. The activities are downloadable PDFs organized by skill and grade. Not OG-branded, but methodologically consistent. ^[13]

The Louisiana Department of Education publishes a free CKLA (Core Knowledge Language Arts) curriculum that includes systematic phonics and is available to any teacher or parent. It's not OG specifically, but it meets the structured literacy standard.

ReadWorks (readworks.org) offers free decodable and leveled texts, though it's less OG-specific than the Florida materials.

For phonemic awareness specifically, the University of Oregon's DIBELS materials (including nonsense word fluency tasks) are free and widely used in schools. ^[13]

The IDA (dyslexiaida.org) maintains a free fact sheet library explaining phoneme-grapheme correspondences, syllable types, and morphology rules, which are exactly the content areas IMSE covers. These won't make you a trained OG practitioner, but they'll help you understand what your child's teacher should be doing.

One honest caution: free piecemeal resources are not a substitute for systematic, sequential instruction delivered by a trained teacher. They can supplement. They can help you practice with your child at home. But if your school isn't providing proper OG-based instruction, a free worksheet won't close the gap. The advocacy work, getting the right instruction into the school day, matters more than any home supplement.

If you want structured home practice tools, sight word flashcards and first grade sight words lists can build automaticity alongside whatever decoding program the school uses. For students with dyslexia, explicit phonics always comes before sight word drilling.

What questions should parents ask the school about their OG program?

Go into any school meeting with specific questions written down. Vague questions get vague answers.

Ask: What structured literacy program does the school use for reading intervention? If the answer is "Orton-Gillingham" or "IMSE," follow up. How many of your teachers are certified at the Practitioner level versus Overview? What scope and sequence is the interventionist currently working through with my child? How often does my child receive this instruction, and for how many minutes each session? Research suggests struggling readers need at least 30 minutes of daily small-group or individual OG-based instruction to make meaningful gains; some studies point to 90 minutes as optimal for students more than two grade levels behind. ^[3]

Ask for the most recent progress monitoring data. IMSE-trained teachers use ongoing informal assessments, but schools should also use a standardized measure like DIBELS or AIMSweb to track growth over time. If the data shows your child has been receiving intervention for six months with no measurable growth in word reading, that's a sign the intervention isn't working, in content or delivery, and the IEP team must reconvene to discuss changes.

Ask whether the teacher who delivers the intervention is the same one your child sees every day or whether it rotates. Consistency matters enormously in OG-based instruction because the diagnostic relationship between teacher and student takes time to develop.

Ask what happens during classroom reading instruction when your child is not in small-group intervention. If the core classroom program uses whole-language or balanced literacy methods that conflict with OG principles, the signals your child receives about how reading works will contradict each other. This is a real and documented problem in schools that are "adding" OG intervention on top of a whole-language core without changing the core itself. ^[2]

For families dealing with specific reading profiles like double deficit dyslexia or rapid naming deficit, understanding those profiles before the meeting helps you ask sharper questions about whether the school's program addresses both phonological and fluency deficits.

Frequently asked questions

Is IMSE the same as Orton-Gillingham?

No. Orton-Gillingham is a teaching approach developed in the 1930s; IMSE is a private company that trains teachers to use that approach. Several other organizations (Wilson, Barton, Lindamood-Bell) also build on OG principles. IMSE is one delivery vehicle, not OG itself. Think of OG as the method and IMSE as one school of instruction in that method.

Can I buy IMSE curriculum materials to use at home?

No. IMSE sells teacher training and accompanying educator materials, not a parent-facing home kit. If you want an OG-based program for home use, Barton Reading and Spelling or All About Reading are better options because both are designed for parents without formal teaching credentials. IMSE is a school and district product.

How long does it take for a teacher to become IMSE certified?

The core Orton-Gillingham Practitioner training is five days of coursework followed by a supervised practicum where the teacher logs a required number of documented teaching hours. The total time from start to certification typically runs three to six months depending on how quickly the teacher completes the practicum. Some districts compress the process with intensive summer institutes.

Is IMSE training approved by the Orton-Gillingham Academy?

IMSE holds its own certification separate from the Academy of Orton-Gillingham Practitioners and Educators (AOGPE), which is the main credentialing body for OG. The two credentials are different. IMSE-certified teachers are not automatically AOGPE-credentialed, and vice versa. For most school settings, IMSE certification is sufficient, but if you're hiring a private tutor, asking which credential they hold matters.

Does IMSE work for kids without dyslexia?

OG-based structured literacy instruction benefits most young readers, not only those with dyslexia. The National Reading Panel's 2000 report found systematic phonics instruction improves reading outcomes for all students. IMSE's methods are most intensively applied with students who have reading disabilities, but the core phonics scope and sequence is appropriate for any child who is learning to read and decode words.

What is the difference between IMSE's Overview and Practitioner courses?

The Overview is an introduction, typically one to two days, that covers OG principles but doesn't qualify a teacher to independently deliver OG-based intervention. The Practitioner course is five days plus supervised practice and qualifies the teacher to work one-on-one or in small groups with students who have significant reading difficulties. For IEP purposes, Practitioner-level training is what you want.

Can I request an IMSE-trained teacher in my child's IEP?

You can request that the IEP specify instruction delivered by a teacher trained in Orton-Gillingham methodology at the Practitioner level. Districts may push back on naming a specific company but should accept methodology-level language. If the school lacks any OG-trained staff, that's relevant to your FAPE argument under IDEA. Document the request in writing and follow up after the meeting.

How do I know if my child needs OG-based instruction versus something else?

A psychoeducational evaluation that includes phonological awareness testing, rapid naming, and decoding assessments will clarify the profile. Students with phonological processing weaknesses (the most common driver of dyslexia) respond best to OG-based approaches. Students whose reading difficulty is primarily a language comprehension issue need a different focus. A school psychologist or private neuropsychologist can map this out. Start with a formal screening if you haven't already.

Does Mississippi's reading improvement come from structured literacy mandates?

Mississippi adopted a statewide reading reform in 2013 that included structured literacy training, third-grade reading retention policies, and expanded K-3 literacy coaches. The state's NAEP fourth-grade reading rank improved from roughly 49th to 21st nationally over about ten years. Researchers credit the combination of those policies rather than any single element, though the structured literacy training component is widely cited as central.

What if my school says it uses Orton-Gillingham but my child still isn't reading?

Start by asking for progress monitoring data. If the data shows minimal growth over three to six months of documented intervention, the problem may be implementation quality, not the method. Request to observe a session if the school allows it, or ask for an IEE at public expense to have an outside specialist evaluate both your child's needs and the school's delivery. IDEA Section 300.502 gives you that right.

Are there free online Orton-Gillingham lesson plans for teachers or parents?

The Florida Center for Reading Research (fcrr.org) publishes free structured literacy activities for K-5. The IDA's website has free fact sheets on phoneme-grapheme correspondences and syllable types. Louisiana's CKLA curriculum is freely available. None of these fully replicate IMSE training, but they provide legitimate structured literacy practice materials without a purchase requirement.

How many minutes per day does OG-based intervention need to run to be effective?

Research suggests a minimum of 30 minutes daily in small groups for students with reading disabilities, with some studies pointing to 90 minutes for students significantly behind grade level. A 2019 meta-analysis in the Journal of Learning Disabilities found effect sizes of 0.40 to 0.76 for OG-based interventions, with more intensive programs (more minutes, smaller groups) showing stronger gains. Ask the school to document session frequency and length in the IEP.

What reading profiles besides dyslexia might benefit from IMSE or OG instruction?

OG-based instruction is most studied for phonological dyslexia, but students with surface dyslexia, mixed reading profiles, and language-based learning disabilities also show gains. Students with attention or processing speed issues often benefit from the multisensory component because it creates redundant encoding. A student whose primary issue is oral language comprehension needs vocabulary and background knowledge work alongside phonics, not instead of it.
