IMSE Orton-Gillingham training: what parents need to know

Last updated 2026-07-09

What is IMSE and what does it actually teach?

IMSE stands for the Institute for Multi-Sensory Education. It started in 1995 and works out of Troy, Michigan. Its main business is training teachers and reading specialists in the Orton-Gillingham approach, the structured literacy method Samuel Orton and Anna Gillingham developed in the 1930s.

Orton-Gillingham is not a single curriculum. It is a set of instructional principles: explicit phonics, multi-sensory learning (seeing, saying, hearing, and writing a sound at the same time), a systematic and sequential lesson structure, and constant diagnostic feedback. IMSE packages those principles into courses teachers can take without leaving their districts, mostly online or in short in-person intensives.

IMSE is one of several groups accredited by the International Dyslexia Association (IDA) to train teachers in OG-based structured literacy. Others include the Academy of Orton-Gillingham Practitioners and Educators (AOGPE), Barton Reading and Spelling, and Wilson Language Training. They differ in format, price, and how closely they follow the original OG protocol. The research base underneath them is the same. ^[1]

Here is what matters for you. A teacher who finished IMSE training has learned an approach that multiple peer-reviewed studies support for kids with dyslexia and other reading difficulties. The National Reading Panel's 2000 report and later meta-analyses keep finding the same thing: systematic phonics beats whole-language and embedded-phonics approaches, especially for the kids who struggle most. ^[2]

How does IMSE's training ladder work?

IMSE builds its Orton-Gillingham programs across four tiers, each one resting on the one below it.

Overview (Foundation Level). A one-day course, about six hours. It introduces teachers to OG principles but does not prepare them to run full OG lessons on their own. It costs roughly $395 as of 2024. A teacher who took only this course should not be sold to parents as an OG-trained tutor. It is awareness-level exposure and nothing more.

Associate Level. Roughly 30 hours of coursework plus supervised practicum hours with students. This level produces teachers who can deliver one-on-one or small-group OG instruction. IMSE calls this the entry point for real OG teaching. Coursework typically runs $995 to $1,195.

Practitioner Level. The most thorough IMSE credential. It requires Associate training, more supervised teaching hours (IMSE requires 100 supervised hours to apply), and passing a review. The Practitioner course adds roughly $500 to $800 on top of Associate. This is the level you want if you are hiring a private tutor for a child with significant dyslexia.

Classroom Educator Level. A track for classroom teachers who need to apply OG principles to whole-class instruction rather than one-on-one work. It does not replace Practitioner for intensive remediation.

IMSE also runs a separate track for dyslexia specialists and administrators, plus a structured literacy curriculum called OG Plus that certified teachers can buy as a ready-made scope and sequence. ^[3]

One thing worth knowing: IMSE credentials are not the same as IDA's own Certified Dyslexia Practitioner (CDP) or Certified Academic Language Therapist (CALT) designations. Those require more supervised hours and independent evaluation. If your child needs intensive intervention, ask about those higher-tier credentials too.

What does the research say about OG-based instruction?

Orton-Gillingham has more research behind it than almost any other reading intervention, but the picture is messier than the marketing suggests.

A 2019 systematic review in the journal *Reading and Writing* looked at 19 studies of OG-based programs. The authors found consistent positive effects on word reading and phonemic awareness, with average effect sizes between 0.40 and 0.70 depending on the outcome. They also flagged that study quality varied and that many studies had no control group. ^[4]

The What Works Clearinghouse (WWC), run by the U.S. Department of Education, reviews individual OG-based programs rather than the OG approach as a whole. Programs like Wilson Reading System (which is OG-based) have earned "positive" or "potentially positive" ratings from WWC for foundational literacy skills. ^[5]

The pieces underneath OG stand on firmer ground than the branded approach itself. Explicit, systematic phonics has strong evidence from dozens of randomized controlled trials. The National Reading Panel in 2000 concluded that systematic phonics produces real benefits for word reading and comprehension, especially for students at risk of reading trouble. ^[2] OG is one structured way to deliver that instruction.

For kids with dyslexia specifically, the evidence gets stronger. A 2012 study in *Annals of Dyslexia* found that OG-based tutoring produced significantly better outcomes on phonological awareness and word attack skills than control conditions among students identified with dyslexia. ^[6]

The honest summary: OG-based instruction works better than most alternatives for struggling readers, especially those with phonological dyslexia or related profiles. It is not magic. Progress is slow. Most kids need 60 to 150 hours of instruction before gains consolidate.

How does IMSE training compare to other OG programs?

Parents and educators keep asking how IMSE stacks up against the competition. Here is a straight comparison.

Program	Accredited by IDA?	Entry-level cost (approx.)	Format	One-on-one vs. classroom focus
IMSE	Yes	$395 (Overview) to $1,195 (Associate)	Online + optional in-person	Both
Wilson Reading System	Yes	~$1,300 (Level I workshop)	In-person intensive	Primarily one-on-one
Barton Reading & Spelling	No (independent)	~$299/level (10 levels)	Self-paced video for tutors	One-on-one
AOGPE Certified OG	Yes (they set the standard)	Varies widely by provider	Coursework + practicum	One-on-one
Lindamood-Bell	No (proprietary)	Training through schools	In-person	Clinic or school setting

IMSE's strengths are cost, flexibility (most of it is online), and reach. The organization says it has trained over 100,000 educators. Its weakness is that online-only training, with no observed teaching and feedback, does not build the same skill as programs that require in-person supervised practicum. The Practitioner track fixes this. The widely-bought Associate and Overview tracks do not require observed teaching.

Wilson is generally seen as the most rigorously structured for severe dyslexia. Barton is the favorite of parents who want to tutor their own child at home, because it needs no special training to start.

If a school claims its reading teachers are OG-trained, ask three things: which program, which level, and when did they finish it? An Overview certificate from 2019 is not the same as a current Practitioner credential with recent practicum hours. ^[3]

What do IMSE courses cost, and who typically pays?

IMSE prices as of 2024 run roughly like this:

• Overview (one day): $395
• Associate Level coursework: $995 to $1,195
• Practitioner Level add-on: $500 to $800
• Classroom Educator: $995 to $1,195

Those are individual prices. IMSE offers district contracts that cut per-seat cost a lot when a school buys in bulk, often $600 to $900 per teacher for Associate-level training.

Who pays? Usually the school district, when it chooses to train its own staff. Some states with dyslexia laws now require reading teachers to get structured literacy training, which pushes schools to buy programs like IMSE. As of 2024, 49 states had passed some form of dyslexia-related legislation, though what they demand of teacher training varies wildly in detail. ^[7]

For private tutors, the cost comes out of pocket unless a family's insurance or a state program covers it. Some states run education savings account (ESA) programs or dyslexia scholarship funds that pay for private tutoring with a certified OG practitioner. Check your state's department of education website for what is available now.

If your child has an IEP and you think the school is not providing appropriate reading instruction, you have the right under IDEA (the Individuals with Disabilities Education Act, 20 U.S.C. § 1400 et seq.) to ask the school to describe the specific instructional methods it uses and to document teacher qualifications. ^[8] You cannot legally demand a specific commercial program by name. You can ask whether staff hold structured literacy training and at what level.

ReadFlare's parent advocacy kit has a template for exactly this kind of records request, which saves you time before an IEP meeting.

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

Fair question, and schools sometimes get loose with the language. A teacher who sat through a one-day overview is not the same as one who finished Associate or Practitioner training. Here is how to check.

First, ask the teacher or special education coordinator straight out: what level of IMSE (or other OG) training do they hold, when did they finish, and did it include supervised practicum hours with students? A trained professional answers all three without stalling.

Second, IMSE issues certificates and keeps records. A teacher can hand you a copy of their certificate showing level and completion date. You are entitled to ask for this, especially if OG instruction is written into your child's IEP as the service delivery method.

Third, IDA keeps an online directory of professionals who hold IDA-recognized credentials (like the Certified Dyslexia Specialist or Certified Academic Language Therapist). Not every IMSE graduate pursues IDA credentialing, but those who do are searchable at the IDA website. ^[1]

A teacher saying the school uses "a structured literacy curriculum" or that they are "familiar with OG" is not a credential. Warmth and a good bond with your child matter. For a child with real signs of dyslexia or a confirmed learning disability, the method has to be systematic and delivered by someone who actually knows how to teach it.

Can parents use OG or IMSE methods at home?

Yes, within limits. You do not need a credential to use OG principles with your own child, and some techniques are simple enough to practice at home to back up what a trained teacher does at school.

The core OG techniques you can use without training:

• Sound-symbol drills with index cards (show the letter, child says the sound; then flip it: say the sound, child writes the letter).
• Phoneme segmentation: say a word, have the child tap or push a chip for each sound.
• Blending chains: start with "at," change to "sat," then "sit," then "bit," one phoneme change at a time.
• Syllable division with two-syllable words, using a physical gesture (tap the desk for each syllable).

What you should not try to copy at home without training: the full diagnostic-prescriptive lesson, where a trained OG teacher adjusts instruction on the fly based on ongoing informal assessment. That part genuinely takes training and practice.

Barton Reading and Spelling, mentioned above, is built for untrained parents to tutor their own kids. If you want to go past casual reinforcement, that is a more honest option than trying to teach yourself the full IMSE curriculum from a teacher's manual.

For drilling specific skills, sight word flashcards and sight words worksheets can round out phonics work. In OG, sight words are taught through phonemic and morphological analysis rather than pure memorization wherever possible. Words like "the" and "said" that genuinely cannot be decoded are called "irregular words" in OG terms, and they are practiced in small sets with multi-sensory reinforcement rather than just repeated visual exposure.

What should parents ask at an IEP or 504 meeting about reading instruction?

Knowing that IMSE and OG training exist hands you a specific vocabulary for these meetings. Here are questions worth asking, with notes on what the answers tell you.

"What specific reading intervention will my child receive, and is it evidence-based?" The school should be able to name the program or approach and point to research support. "We use a balanced literacy approach" is not an acceptable answer for a child with a reading disability. Balanced literacy has weaker evidence than structured literacy for kids with dyslexia. ^[9]

"What structured literacy or OG training does the teacher giving that intervention hold?" If they say "we've done some OG-based professional development," ask for specifics: which organization, which level, how many hours.

"How many minutes per day of explicit phonics instruction will my child get?" For kids with dyslexia, research points to at least 30 minutes of daily, one-on-one or very small-group explicit instruction. Some researchers recommend 45 to 60 minutes for severe cases.

"How will we measure progress, and how often?" A well-run intervention monitors progress every one to two weeks using a curriculum-based measure like DIBELS or AIMSweb. If the school only checks progress quarterly on a standardized test, that is too slow to adjust instruction.

Under IDEA, the school must provide your child a Free Appropriate Public Education (FAPE) in the Least Restrictive Environment. The statute defines FAPE as "special education and related services that... are provided in conformity with the individualized education program" at no cost to parents. ^[8] If you believe the school's reading instruction is not appropriate for your child, you have the right to request an Independent Educational Evaluation (IEE) at public expense.

If your child has not been formally evaluated yet, a dyslexia test or a broader learning disability test through the school is where you start. Request one in writing. In most states the school has 60 days to respond. ^[8]

What are the limits of IMSE and OG training?

Honest answer: Orton-Gillingham training does not guarantee good teaching, and IMSE certification is not the only road to becoming an effective reading teacher.

The first limit is fidelity. A teacher can hold an IMSE Associate certificate and still teach poorly if lessons are rushed, if they skip phonemic awareness because it feels too basic, or if they wander off the structured sequence. Certification tells you someone was trained. It does not tell you how well they teach.

The second limit is time. OG remediation is slow by design, because it builds mastery at each step before moving on. A child with significant dyslexia may need two to three years of consistent instruction before reading becomes automatic. Schools under scheduling pressure sometimes cut the intensity or length of services before kids have locked in their gains. Watch for that.

The third limit is scope. OG alone does not fix every reading problem. A child with a double deficit dyslexia profile (both phonological and naming-speed deficits) may need extra fluency work that standard OG protocols do not emphasize. A child whose comprehension trouble goes past decoding needs vocabulary and language instruction alongside phonics. And a child whose main issue is something other than phonological processing, like surface dyslexia or rapid naming deficit, may need a different emphasis than classic OG.

None of this makes OG or IMSE training a bad idea. It means you should keep asking whether the instruction is actually working, rather than whether it carries a credentialed name. Progress monitoring data is the only real answer.

How do state dyslexia laws affect whether your school offers OG-based instruction?

This landscape has shifted hard in the past decade. As of 2024, 49 states have passed some form of dyslexia legislation, up from fewer than 20 ten years ago. Many of these laws require schools to screen students for dyslexia risk, use evidence-based reading instruction, and train teachers in structured literacy methods. ^[7]

The laws vary enormously. Some states (Texas, Arkansas, and Louisiana get cited as strong examples) spell out that interventions must use structured literacy and that teachers must complete approved training hours. Others are largely definitional, requiring schools to define dyslexia in their policies without mandating any specific approach.

IMSE tracks these laws and markets to districts in states with training mandates, because its courses are an efficient way for a district to document compliance. If your state has a structured literacy mandate, the district has a legal reason to train its staff. That gives you a strong point to press in an IEP conversation.

IDA publishes a state-by-state legislative guide (updated annually) that lists what each state requires. ^[1] If your state's law requires structured literacy training and your child's teacher cannot document any, that is a specific gap to raise with the principal or director of special education, in writing rather than only at an IEP meeting.

For a broader look at how schools must serve children with reading disabilities, the U.S. Department of Education's IDEA site is the primary federal reference. ^[8] IDEA does not mandate OG by name, but it does require that special education services be based on peer-reviewed research to the extent practicable. That is language worth knowing.

How to find an IMSE-trained tutor or evaluate a school's program

Finding a genuinely qualified tutor takes legwork. Here is a practical approach.

Start with IDA's online provider directory at dyslexiaida.org. Search by zip code for people with IDA-recognized credentials. Many hold IMSE Practitioner or equivalent training. ^[1]

Also try the IMSE website (imse.com), which has a "find a provider" or graduate directory that lets you search by location for people who finished their training. This list is broader than IDA's because it includes Associate-level graduates, so follow up by asking what level they completed.

When you interview a potential tutor, ask:

• How many students with dyslexia have you worked with, and for how long?
• What does a typical 50-minute lesson look like?
• How do you track progress between sessions?
• What do you do when a student is not progressing as expected?

A good OG practitioner describes a structured lesson: review of previously taught phonics patterns, introduction of a new concept, guided and independent practice, and a sight-word or irregular-word component. They should run some form of progress monitoring every one to two weeks.

To evaluate a school program, ask for the reading curriculum documentation and the names of any structured literacy programs they use. Then check those programs against the WWC database and IDA's Knowledge and Practice Standards for Teachers of Reading. ^[5] A program with no third-party evidence review is a red flag.

ReadFlare's free reading tools include a parent checklist for judging whether your child's reading instruction meets the basic marks of structured literacy, which is a good starting point before a school meeting.

If your child has not been screened yet, learning the signs of dyslexia and getting a formal dyslexia test come first, before you worry about which program the school will use.

Frequently asked questions

Is IMSE the same as Orton-Gillingham?

No. Orton-Gillingham is an instructional approach developed in the 1930s, not a single program or organization. IMSE is one of several groups that trains teachers in OG methods. Others include Wilson Language Training, the Academy of OG Practitioners and Educators (AOGPE), and Barton. IMSE is IDA-accredited, which means its training meets the International Dyslexia Association's standards for structured literacy instruction.

How long does IMSE certification take?

The Overview course is one day (about six hours). The Associate Level takes roughly 30 hours of coursework, usually spread over several days or done online across a few weeks. The Practitioner credential requires Associate training plus 100 supervised teaching hours, which can take one to two school years depending on caseload. Full Practitioner certification is not a quick process.

Can a parent take IMSE training to help their own child?

Technically yes. IMSE does not restrict enrollment to credentialed educators. In practice, the courses are built for teachers and assume basic literacy instruction knowledge. For parents wanting to tutor their own child, Barton Reading and Spelling is a more accessible start because it was designed for untrained tutors. OG principles can also be applied informally at home to back up school instruction.

Does IMSE training qualify a teacher to diagnose dyslexia?

No. IMSE training qualifies a teacher to deliver structured literacy instruction, not to diagnose dyslexia or other learning disabilities. Diagnosis takes a full psychoeducational evaluation by a licensed psychologist, educational diagnostician, or neuropsychologist. IMSE-trained teachers can screen for risk and observe reading behaviors, but formal diagnosis is a separate professional job.

How much does an IMSE-trained private tutor typically charge per session?

Rates vary a lot by region and credential level. Based on tutor marketplace data and IDA guidance, certified OG tutors typically charge $60 to $150 per hour as of 2024. Practitioners with IDA-recognized credentials or CALTs often charge $100 to $180 per hour. IMSE does not set these rates. Always ask what level of training a tutor holds before you assume their rate reflects OG Practitioner-level skill.

Can I request that my child's IEP specifically name Orton-Gillingham or IMSE as the required method?

You can request it, but schools are not legally required to use a specific named commercial program. IDEA requires that special education services be based on peer-reviewed research to the extent practicable, which supports requesting structured literacy generally. The more productive move is often requesting that the IEP specify the type of instruction (explicit, systematic, multi-sensory phonics), session frequency, and how teacher qualifications will be documented.

What is the difference between IMSE Associate and Practitioner levels?

Associate-level training (about 30 coursework hours) prepares a teacher to deliver OG lessons in a school setting. Practitioner level requires completing Associate training plus 100 supervised teaching hours with feedback from a qualified mentor, which makes it far more rigorous. For one-on-one intensive intervention with a child who has significant dyslexia, Practitioner level is the credential to look for in a private tutor.

Are there free or low-cost alternatives to IMSE-trained tutoring?

Yes. Some university reading clinics offer subsidized tutoring from supervised graduate students trained in OG methods. Many local literacy councils offer free tutoring, though quality varies. Some states run dyslexia scholarship or education savings account programs that cover private tutoring. Your school district is also required under IDEA to provide appropriate reading intervention at no cost if your child qualifies for special education services.

How do I know if my child needs OG-based instruction vs. a general phonics program?

Kids who fail to respond to good general phonics after 12 to 20 weeks of consistent exposure are candidates for more intensive structured literacy, usually OG-based. Children with a confirmed dyslexia diagnosis, phonological processing deficits, or a profile showing both phonological and rapid-naming weaknesses (sometimes called double-deficit) are strong candidates for the full OG approach rather than a lighter phonics program.

What does 'IDA-accredited' mean for an OG training program?

The International Dyslexia Association reviews training programs against its Knowledge and Practice Standards for Teachers of Reading. An IDA-accredited program has been independently evaluated and confirmed to cover the phonological awareness, phonics, morphology, syntax, and structured literacy components the standards require. IMSE holds this accreditation. It is a meaningful quality signal, though it does not guarantee individual instructors are excellent.

How long before my child shows progress with OG instruction?

Research suggests most students with dyslexia need 60 to 150 hours of structured OG instruction before locking in meaningful gains in word reading accuracy. That is roughly one to two school years of daily 30-minute sessions. Fluency improvements usually lag accuracy by several months. Progress monitoring data every one to two weeks is the only reliable way to know if instruction is working, rather than waiting for the next annual standardized test.

Is IMSE training relevant for math difficulties or only reading?

IMSE focuses on reading and literacy and does not address math. If your child also struggles with math, that may reflect a separate condition sometimes called dyscalculia or number dyslexia. Reading-focused OG training will not touch numeracy weaknesses. A separate evaluation and a different intervention are needed for math. You can learn more in our article on number dyslexia.

What states require structured literacy or OG-based teacher training?

As of 2024, states with the most specific structured literacy training requirements include Texas (with its Dyslexia Handbook), Arkansas (LEARNS Act), Louisiana, Ohio, and Mississippi. These states specify approved training hours and content built on IDA standards. Most other states have dyslexia identification requirements but less detail about instructional mandates. Check your state department of education website or IDA's annual legislative update for current rules.
