If you teach reading, you have likely heard the term “structured literacy” more and more in recent years. With over 40 states now passing legislation aligned with the Science of Reading, understanding this framework is no longer optional for educators. But knowing the name is not the same as knowing the method. To teach structured literacy effectively, you need to understand its six core components and how each one contributes to building a strong reader.
This guide breaks down the six components of structured literacy as defined by the International Dyslexia Association (IDA). For each component, you will learn what it is, why it matters, and how to apply it in your classroom. Whether you teach general education, special education, or work as a reading interventionist, this knowledge will make you a more effective literacy instructor.
What Is Structured Literacy?
Structured literacy is a comprehensive, evidence-based approach to reading instruction that is explicit, systematic, cumulative, and diagnostic. Unlike approaches that rely on context clues or picture cues to help students guess at words, structured literacy teaches the rules and patterns of the English language directly. Every concept is introduced in a logical sequence, with each lesson building on the skills mastered in previous lessons.
The term was coined by the International Dyslexia Association to describe the instructional approach supported by the Science of Reading. This body of research from cognitive science, neuroscience, and education tells us that reading is not a natural process. It must be explicitly taught. Structured literacy is the practical framework that puts this research into classroom practice.
What makes structured literacy so effective is that it addresses both word recognition and language comprehension through six interconnected components. These components, when taught together in a systematic way, give students a complete toolkit for decoding, spelling, and understanding text.
The 6 Components of Structured Literacy
The IDA identifies six components that form the foundation of structured literacy instruction. Each one targets a specific aspect of language, and together they create a comprehensive framework for teaching reading.
1. Phonology: Understanding the Sounds of Language
Phonology is the study of the sound structure of spoken language. It includes phonemic awareness, which is the ability to identify, isolate, blend, and manipulate individual sounds (phonemes) in words. This is the starting point of all reading instruction because students must be able to hear and distinguish sounds before they can connect those sounds to letters.
Why it matters: Research consistently shows that phonemic awareness is one of the strongest predictors of reading success. Students who struggle with phonological processing often struggle with reading and spelling, which is why this skill is a hallmark characteristic of dyslexia.
Teaching example: Have students practice segmenting words into individual sounds. For the word “ship,” a student would identify three phonemes: /sh/ /i/ /p/. Use sound boxes (Elkonin boxes) where students push a token into a box for each sound they hear. This multisensory technique, central to the Orton-Gillingham approach, builds strong phonological processing skills.
2. Sound-Symbol Association: Connecting Sounds to Letters
Sound-symbol association, also called phonics or the alphabetic principle, is the explicit teaching of the relationships between sounds (phonemes) and their written representations (graphemes). This includes single letters, letter teams like “sh” and “oa,” and more complex spelling patterns.
Why it matters: English has approximately 44 phonemes represented by over 250 graphemes. Students cannot simply memorize every word; they need to understand the code that connects speech to print. Systematic phonics instruction gives students a reliable decoding strategy that works with virtually every word they encounter.
Teaching example: When introducing the phonogram “igh” (as in “light,” “night,” “right”), teach it explicitly as a three-letter team that represents the long /i/ sound. Have students see the letters, say the sound, and trace the letters on a textured surface. Then practice reading and spelling words with “igh” in controlled, decodable text. This systematic approach to sound-symbol mapping is far more effective than asking students to memorize whole words by sight.
3. Syllable Instruction: Decoding Longer Words
Syllable instruction teaches students the six syllable types in English so they can break multisyllabic words into manageable parts. The six types are: closed (CVC, like “nap”), open (CV, like “me”), vowel-consonant-e (VCe, like “name”), vowel team (like “rain”), r-controlled (like “car”), and consonant-le (like “table”).
Why it matters: Many students hit a wall in second or third grade when words get longer. Without syllable knowledge, students have no strategy for tackling words like “fantastic” or “locomotive.” Syllable instruction gives them a predictable system for breaking words apart, identifying the vowel sound in each syllable, and blending them back together.
Teaching example: Present the word “sunset” and guide students through dividing it between the two consonants (sun-set). Identify each syllable type: “sun” is a closed syllable (the vowel is followed by a consonant, making it short), and “set” is also a closed syllable. Students can then decode each part independently and blend them. Over time, this skill becomes automatic, allowing students to read multisyllabic words fluently.
4. Morphology: Learning the Meaningful Parts of Words
Morphology is the study of morphemes, the smallest units of meaning in language. This includes prefixes (un-, re-, pre-), suffixes (-ing, -tion, -ful), base words, and roots (often from Latin and Greek origins). Structured literacy teaches students to recognize and use these meaningful word parts to decode, spell, and understand unfamiliar words.
Why it matters: Morphological knowledge is a powerful tool for vocabulary expansion and reading comprehension. Research shows that approximately 60% of English words have Latin or Greek roots. When students understand how morphemes work, they can figure out the meaning of thousands of words they have never seen before. It also improves spelling accuracy because morphological patterns are consistent even when pronunciation changes.
Teaching example: Teach the Latin root “rupt” (meaning “to break”). Show students how it appears in “disrupt” (to break apart), “interrupt” (to break into), “erupt” (to break out), and “corrupt” (to break thoroughly). Have them build words using a word matrix, combining prefixes and suffixes with the root. This exercise demonstrates that English spelling is logical and predictable when you understand the morphological structure.
5. Syntax: Understanding Grammar and Sentence Structure
Syntax refers to the rules that govern how words are organized into phrases, clauses, and sentences. In structured literacy, syntax instruction includes grammar, sentence structure, punctuation, and the mechanics of written language. Students learn how the arrangement of words affects meaning and how to construct grammatically correct sentences.
Why it matters: Reading is more than decoding individual words. Students must also understand how those words work together in sentences to convey meaning. Syntax instruction helps students parse complex sentences, understand relationships between ideas, and become stronger writers. Students with language-based learning differences often struggle with sentence-level comprehension, making explicit syntax instruction essential.
Teaching example: Show students two sentences: “The dog chased the cat” and “The cat chased the dog.” Both use the same words, but the meaning changes based on word order. Progress to teaching students how to combine short sentences into compound and complex sentences using conjunctions and relative clauses. For example, combine “The student read the book” and “The book was about volcanoes” into “The student read the book that was about volcanoes.” Explicit practice with sentence combining builds both comprehension and writing skills.
6. Semantics: Building Meaning and Comprehension
Semantics is the study of meaning in language. It encompasses vocabulary development, reading comprehension, and the ability to understand figurative language, idioms, and multiple-meaning words. While the first five components focus heavily on the mechanics of reading, semantics ties everything together by ensuring students understand what they read.
Why it matters: The ultimate goal of reading is comprehension. Students who can decode fluently but do not understand vocabulary or how to extract meaning from text are not truly reading. Semantics instruction builds the language comprehension side of the reading equation, which becomes increasingly important as students encounter more complex academic texts.
Teaching example: When teaching the word “bank,” discuss its multiple meanings: the bank of a river, a financial bank, to bank a basketball off the backboard. Have students use context clues within sentences to determine which meaning applies. For figurative language, teach phrases like “break the ice” by first discussing the literal meaning, then the figurative meaning, and having students practice using the phrase in context. Building a rich vocabulary through direct instruction, rather than hoping students absorb it through reading alone, is a hallmark of effective structured literacy.
How Structured Literacy Differs from Balanced Literacy
Many educators were trained in balanced literacy, an approach that combines whole language philosophy with some phonics. In balanced literacy classrooms, students often use three-cueing strategies: they look at the picture, think about what word would make sense, or skip and come back to a tricky word.
Structured literacy takes a fundamentally different approach. Instead of teaching students to guess at words, it teaches them to decode words by applying their knowledge of sounds, syllables, and morphemes. Here are the key differences:
- Phonics is the primary strategy, not one of many. In structured literacy, students learn to look at the letters, identify the sounds, and blend. There is no guessing.
- Instruction follows a scope and sequence. Every skill is taught in a logical, cumulative order. Nothing is left to chance or incidental teaching moments.
- Decodable texts replace leveled readers in early instruction. Students practice reading texts that contain only the phonics patterns they have been explicitly taught.
- Assessment is diagnostic. Teachers pinpoint specific skill gaps rather than relying on reading levels to group students.
This is not about discarding everything from balanced literacy. Read-alouds, independent reading, and rich literature still play important roles in building vocabulary and comprehension. The difference is that these activities supplement, rather than replace, explicit and systematic instruction in the code of the English language.
How Orton-Gillingham Puts Structured Literacy into Practice
The Orton-Gillingham approach is widely regarded as the gold standard for structured literacy instruction. Developed in the 1930s by Dr. Samuel Orton and educator Anna Gillingham, this method was designed specifically for students with dyslexia but has proven effective for all learners.
Orton-Gillingham instruction is:
- Multisensory: Students see, hear, say, and write language simultaneously. This engages multiple neural pathways and helps cement learning in memory.
- Explicit and direct: Every rule and pattern is taught clearly. Nothing is left for students to figure out on their own.
- Systematic and cumulative: Skills are introduced in a carefully planned sequence, with each lesson building on what came before.
- Diagnostic and prescriptive: Teachers continuously assess student understanding and adjust instruction to meet individual needs.
Programs built on the Orton-Gillingham framework, like the PRIDE Reading Program, provide fully scripted lessons that cover all six components of structured literacy. This means teachers and tutors can deliver effective, research-based instruction without years of specialized training. The program includes built-in progress monitoring, multisensory activities, and a clear scope and sequence that ensures every student builds a strong literacy foundation.
For homeschool families, a structured approach like this provides the confidence that comes from following a proven, step-by-step curriculum. And for students who need additional one-on-one support, PRIDE Reading Specialists offer personalized tutoring sessions grounded in Orton-Gillingham methods.
Frequently Asked Questions
What are the 6 components of structured literacy?
The six components of structured literacy, as defined by the International Dyslexia Association, are phonology (speech sounds), sound-symbol association (phonics), syllable instruction (the six syllable types), morphology (prefixes, suffixes, and roots), syntax (grammar and sentence structure), and semantics (meaning and comprehension). Together, these components provide a complete framework for teaching reading.
Is structured literacy only for students with dyslexia?
No. While structured literacy is essential for students with dyslexia and other language-based learning differences, research shows that it benefits all learners. Its explicit, systematic approach prevents gaps in foundational reading skills and gives every student a reliable strategy for decoding and understanding text. About 95% of students can learn to read proficiently when taught with structured literacy methods.
How is structured literacy different from phonics?
Phonics is one component of structured literacy, specifically the sound-symbol association component. Structured literacy goes beyond phonics alone by also teaching phonological awareness, syllable types, morphology, syntax, and semantics. It is a comprehensive framework that addresses every aspect of reading and language, not just letter-sound relationships.
What is the connection between structured literacy and the Science of Reading?
The Science of Reading is the body of research from cognitive science, neuroscience, and education that explains how the brain learns to read. Structured literacy is the practical, classroom-ready framework that puts this research into action. When a program is aligned with the Science of Reading, it means it teaches reading in a way that matches how the brain actually processes written language.
How do I get started teaching structured literacy in my classroom?
Start by evaluating your current reading instruction against the six components. Identify where you are providing explicit, systematic instruction and where there are gaps. Then choose a curriculum built on the Orton-Gillingham approach that covers all six components and provides a clear scope and sequence. Look for programs that are fully scripted and include progress monitoring tools, so you can begin delivering effective instruction immediately.
