Evidenced-Based Dyslexia Instruction
While the components of instruction for students with dyslexia include good teaching principles for all teachers, the explicitness and intensity of the instruction, fidelity to program descriptors, grouping formats, and training and skill of the teachers are wholly different from core classroom instruction and must be considered when making individual placement decisions.
For the student who has not benefited from the research-based core reading instruction, the components of instruction will include additional focused intervention as appropriate for the reading needs of the student with dyslexia. Evidence-based dyslexia instruction provides evidence-based, multisensory structured literacy instruction for students with dyslexia. This instruction must be explicit, systematic, and intentional in its approach. This instruction is designed to likely take place in a small group setting.
Evidenced-based instruction must be:
Evidence-based and effective for students with dyslexia
Taught by an appropriately trained instructor
Implemented with fidelity
Evidence-based dyslexia programs and instruction are considered specially designed instruction (SDI) and therefore special education services, so the provision of those services must follow the IDEA requirements. This means that evidence-based dyslexia instruction is only available to students who are served under IDEA, which prescribes the legal requirements for special education and related services

Critical Evidenced-Based Components
TEA Dyslexia Handbook, 2024
Phonological Awareness
"Phonological awareness is the understanding of the internal sound structure of words. A phoneme is the smallest unit of sound in a given language that can be recognized as being distinct from other sounds. An important aspect of phonological awareness is the ability to segment spoken words into their component phonemes [phonemic awareness].” (Birsh, 2018, p. 26).
Sound Symbol Association
Sound-symbol association is the knowledge of the various speech sounds in any language to the corresponding letter or letter combinations that represent those speech sounds. The mastery of sound-symbol association (alphabetic principle) is the foundation for the ability to read (decode) and spell (encode) (Birsh, 2018, p. 26). “Explicit phonics refers to an organized program in which these sound symbol correspondences are taught systematically” (Berninger & Wolf, 2009, p. 53).
Syllabication
“A syllable is a unit of oral or written language with one vowel sound. Instruction must include the six basic types of syllables in the English language; closed, open, vowel-consonant- e, r-controlled, vowel pair (or vowel team), and final stable syllable. Syllable division rules must be directly taught in relation to the word structure” (Birsh, 2018, p. 26).
Orthography
Orthography is the written spelling patterns and rules in a given language. Students must be taught the regularity and irregularity of the orthographic patterns of a language in an explicit and systematic manner. The instruction should be integrated with phonology and sound- symbol knowledge.
Morphology
“Morphology is the study of how morphemes are combined to form words. A morpheme is the smallest unit of meaning in the language” (Birsh, 2018, p. 26).
Syntax
“Syntax is the set of principles that dictate sequence and function of words in a sentence in order to convey meaning. This includes grammar, sentence variation, and the mechanics of language” (Birsh, 2018, p. 26).
Reading Comprehension
Reading comprehension is the process of extracting and constructing meaning through the interaction of the reader with the text to be comprehended and the specific purpose for reading. The reader’s skill in reading comprehension depends upon the development of accurate and fluent word recognition, oral language development (especially vocabulary and listening comprehension), background knowledge, use of appropriate strategies to enhance comprehension and repair it if it breaks down, and the reader’s interest in what he or she is reading and motivation to comprehend its meaning (Birsh, 2018, p.14; Snow, 2002).
Reading Fluency
“Reading fluency is the ability to read text with sufficient speed and accuracy to support comprehension”(Moats & Dakin, 2008, p. 52). Fluency also includes prosody. Teachers can help promote fluency with several interventions that have proven successful in helping students with fluency (e.g., repeated readings, word lists, and choral reading of passages) (Henry, 2010, p. 104).
Delivery of Dyslexia Instruction
TEA Dyslexia Handbook, 2024
Simultaneous, Multisensory (VAKT)
“Teaching is done using all learning pathways in the brain (visual, auditory, kinesthetic, tactile) simultaneously in order to enhance memory and learning” (Birsh, 2018, p. 26). “Children are actively engaged in learning language concepts and other information, often by using their hands, arms, mouths, eyes, and whole bodies while learning” (Moats & Dakin, 2008, p. 58).
Systematic and Cumulative
“Multisensory language instruction requires that the organization of material follow order of the language. The sequence must begin with the easiest concepts and most basic elements and progress methodically to more difficult material. Each step must also be based on [elements] already learned. Concepts taught must be systematically reviewed to strengthen memory” (Birsh, 2018, p. 26)
Explicit Instruction
“Explicit instruction is explained and demonstrated by the teacher one language and print concept at a time, rather than left to discovery through incidental encounters with information. Poor readers do not learn that print represents speech simply from exposure to books or print” (Moats & Dakin, 2008, p. 58). Explicit Instruction is “an approach that involves direct instruction: The teacher demonstrates the task and provides guided practice with immediate corrective feedback before the student attempts the task independently” (Mather & Wendling, 2012, p. 326).
Diagnostic Teaching to Automaticity
“The teacher must be adept at prescriptive or individualized teaching. The teaching plan is based on careful and [continual] assessment of the individual’s needs. The content presented must be mastered to the degree of automaticity” (Birsh, 2018, p. 27). “This teacher knowledge is essential for guiding the content and emphasis of instruction for the individual student”(Moats & Dakin, 2008, p. 58). “When a reading skill becomes automatic (direct access without conscious awareness), it is performed quickly in an efficient manner” (Berninger & Wolf, 2009, p. 70).
Synthetic Instruction
“Synthetic instruction presents the parts of the language and then teaches how the parts work together to form a whole” (Birsh, 2018, p. 27).
Analytic Instruction
“Analytic instruction presents the whole and teaches how this can be broken into its component parts” (Birsh, 2018, p. 27).
Research-Based Practices
TEA Dyslexia Handbook, 2024
It is important to note that in Texas, the approach to teaching students with dyslexia is founded on research- based best practices. The ideas upon which the state’s approach is based are summarized here.
• Gains in reading can be significant if students with reading problems are provided systematic, explicit, and intensive reading instruction of sufficient duration in phonemic awareness, phonics, fluency, vocabulary (e.g., the relationships among words and the relationships among word structure, origin, and meaning), reading comprehension strategies, and writing.
• A failure to learn to read impacts a person’s life significantly. The key to preventing this failure for students with dyslexia is early identification and early intervention.
• Instruction by a highly skilled and knowledgeable educator who has specific preparation in the remediation of dyslexia is necessary.
Dysgraphia
TEA Dyslexia Handbook, 2024
Handwriting Hierarchy of Instruction
Posture
Also known as “Watch Our Writing” (W.O.W)
• Feet are flat on the floor
• Back is straight
• Paper slanted so that the edge of the paper is parallel to the writing arm
• Paper anchored with non-writing hand
• Pencil grip and position correct
Grip
Normal tripod grip with pencil resting on first joint of middle finger with the thumb and index fingers holding the pencil in place at a 45° angle.
Letter Formation
Emphasis placed in the following order:
• Shape
• Proportion
• Size
• Rhythm/fluency
• Slant
Sequence
• Lower case letters first; Capitals as needed beginning with first letters of student name
• Manuscript – group by stroke formation
• Cursive – group by beginning approach stroke
• Letters
• Syllables
• Words
• Phrases
• Sentences
• Paragraphs
Spelling
Handwriting supports spelling, a complex process of translating a phoneme (spoken sound) to the corresponding grapheme (orthographic representation) in order to generate written text to express an idea. Orthography is the written spelling patterns and rules in a given language. Students must be taught the regularity and irregularity of the orthographic patterns of a language in an explicit and systematic manner. The instruction should be integrated with phonology and sound-symbol knowledge.
Because spelling is meaning driven and draws upon the phonological, orthographic, and morphological aspects of words, students will benefit from systematic, explicit instruction based on the following guiding principles:
• Phoneme-grapheme correspondence
• Letter order and sequence patterns, or orthographic conventions:
○ syllable types
○ orthographic rules
○ irregular words
• Position of a phoneme or grapheme in a word
• Meaning (morphology) and part of speech
• Language of origin (Moats, 2005)
Writing
A potential secondary consequence of dysgraphia is difficulty with students expressing themselves in written text. This difficulty may be attributed to deficits in handwriting, spelling, language processing, or the integration of each of those skills. In Chapter 4 of this handbook, Moats and Dakin (2008) are quoted as stating:
The ability to compose and transcribe conventional English with accuracy, fluency, and clarity of expression is known as basic writing skills. Writing is dependent on many language skills and processes and is often even more problematic for children than reading. Writing is a language discipline with many component skills that must be directly taught. Because writing demands using different skills at the same time, such as generating language, spelling, handwriting, and using capitalization and punctuation, it puts a significant demand on working memory and attention. Thus, a student may demonstrate mastery of these individual skills, but when asked to integrate them all at once, mastery of an individual skill, such as handwriting, often deteriorates. To write on demand, a student has to have mastered, to the point of being automatic, each skill involved (p. 55).
Students with written expression difficulties because of dysgraphia would benefit from being taught explicit strategies for composing including planning, generating, reviewing/evaluating, and revising different genre including narrative, informational, compare and contrast, and persuasive compositions (IDA, 2012).
