Structured literacy / Orton-Gillingham approaches

Structured Literacy is a highly organized teaching approach for reading that breaks down language into its smallest parts and teaches it directly and systematically, which is especially effective for students with dyslexia.

What it means, in plain words

Structured Literacy is not one specific program, but a type of instruction. It is an umbrella term for teaching methods that emphasize the structure of language. This approach teaches reading and spelling in a way that is explicit, systematic, and cumulative. 'Explicit' means the teacher directly explains each concept and does not leave anything to guesswork. 'Systematic and cumulative' means skills are taught in a logical order, building from simple concepts (like the sound of the letter 'b') to more complex ones (like reading multi-syllable words).

This approach directly teaches several key elements of language, including: phonology (the sound structure of words), sound-symbol association (phonics), syllable types, morphology (the parts of words that have meaning, like prefixes and roots), syntax (how sentences are formed), and semantics (the meaning of words and sentences). The goal is to give students a reliable strategy for reading and spelling any word, rather than asking them to memorize or guess.

Orton-Gillingham (O-G) is the original Structured Literacy approach, developed in the 1930s. Many modern reading programs, like Wilson and Barton, are based on O-G principles. These programs are often multisensory, meaning they use sight, sound, and touch to help students learn and remember concepts.

What support can do for them

Students with dyslexia or other reading-based learning disabilities do not learn to read effortlessly. Their brains have difficulty connecting the sounds of language to the letters that represent them. Structured Literacy helps by making these connections clear and predictable. Instead of being expected to 'absorb' reading rules, students are taught them directly, one by one.

Because the instruction is cumulative, each new lesson builds on skills the student has already mastered. This prevents gaps in knowledge and builds a strong foundation. For a struggling reader, this systematic approach can reduce the anxiety and frustration of trying to guess at words. It provides a reliable roadmap for decoding and spelling that they can use for the rest of their lives.

Things you're allowed to ask
  • What specific, research-based reading program are you proposing to use?
  • What training and certification does the teacher or interventionist have in this specific program?
  • How will the program be implemented? Specifically, what will be the frequency (how many days per week), duration (how many minutes per session), and group size?
  • How will you ensure the program is delivered with fidelity, meaning exactly as the program designers intended?
  • What specific skills will you be measuring to track my child's progress, and how often will you collect and share that data with me?
  • What do you consider to be an adequate rate of progress for my child in this intervention?
  • How are lessons adapted to meet my child's individual needs?
  • If the data shows my child is not making adequate progress after a set amount of time (e.g., 6-8 weeks), what is the plan to change the intervention?
When it helps most

Structured Literacy is considered a gold-standard intervention for students with dyslexia. It is most effective for students who struggle with phonemic awareness (hearing individual sounds in words) and phonics (connecting sounds to letters). This approach is often recommended in an IEP when a student has not made progress with less intensive reading support.

Structured literacy is most effective when started early. The earlier a child with reading difficulties begins receiving structured literacy instruction, the better their outcomes tend to be. However, it can also be effective for older students who have struggled with traditional reading approaches. The systematic and individualized nature of these methods allows instruction to be tailored to the needs of diverse learners across various ages.

When it may not help

A Structured Literacy program may be less effective if it is not implemented correctly. This is called 'implementation fidelity.' If the teacher is not properly trained in the specific program, if sessions are too short or infrequent, or if the group size is too large, the student may not make progress. This is not a failure of the approach, but a failure of the delivery.

Additionally, while Structured Literacy is powerful for teaching decoding and spelling, it is only one piece of the reading puzzle. A student may also need separate, explicit instruction in vocabulary and reading comprehension. If a student's primary struggle is with understanding what they read (comprehension) and not with sounding out the words (decoding), a Structured Literacy program alone may not be enough to close the gap.

Students who require additional support for issues unrelated to dyslexia or SLD, such as attention deficits, may need supplementary interventions alongside structured literacy instruction.

Common variations

Many different commercial programs are based on Structured Literacy and Orton-Gillingham principles. It is helpful for parents to recognize the names of common programs their school might use. Some well-known examples include:

  • Wilson Reading System
  • Barton Reading & Spelling System
  • S.P.I.R.E. (Specialized Program in Reading Excellence)
  • Lindamood-Bell programs (such as LiPS for phonemic awareness)
  • RAVE-O (Reading with Automatized, Vocabulary, Engagement, and Orthography)

Each program has its own specific training requirements, materials, and lesson structure, but they all share the core principles of being explicit, systematic, cumulative, and often multisensory.

How to know it's working

The school should be tracking your child's progress with data, a process called 'progress monitoring.' You should not have to wait for a report card to know if the intervention is working. The school should provide you with easy-to-read charts or graphs at least every 4-6 weeks showing your child's performance on specific skills taught in the program.

This data might track things like accuracy in reading lists of taught words, nonsense word fluency, or oral reading fluency on passages using words the student has learned. The data should show a clear, steady trend of improvement. If the data is flat or going down, the IEP team needs to meet to discuss why and make changes.

It's also important to see a reduction in frustration and an increase in your child's confidence as they become more proficient readers.

What to watch for

Be cautious if the school says they are 'using an Orton-Gillingham approach' but cannot name a specific, evidence-based program. This can sometimes mean an instructor is using a mix of worksheets or activities that are not systematic or cumulative.

Watch for poor implementation. The intervention must be provided consistently for the recommended frequency and duration (e.g., 45 minutes, 4 times per week) by a person with specific training in that program. Make sure that teachers are adequately trained in the specific approach being used and that they follow a consistent, step-by-step methodology.

If progress data is not being collected or shared, it is impossible to know if the intervention is truly working for your child.

Research basis

The principles behind Structured Literacy are supported by a large body of scientific research, often called the 'Science of Reading.' The National Reading Panel's 2000 report concluded that students benefit from explicit, systematic instruction in phonemic awareness and phonics. More recent reviews of evidence by organizations like the What Works Clearinghouse confirm that programs including these components have positive effects on early reading skills.

While the term 'Structured Literacy' itself is promoted by the International Dyslexia Association, its components are aligned with decades of research on effective reading instruction. The evidence strongly supports this type of direct, systematic teaching for students who struggle with word-level reading, especially those with dyslexia.

How SENTINEL·IEP helps with this

Understanding the topic is one thing; using it in a meeting is another. SENTINEL·IEP gives you plain-language reference and a companion that follows the conversation in real time — so you can recognize this when it comes up and know what to ask.

SENTINEL·IEP gives you knowledge, structure, and a companion in the room. It is not a law firm, and not a substitute for advice about your own child. For that, a special education attorney or your state's Parent Training and Information Center is the right call — and we'll always point you there when it matters.
