Reading and Writing Disorders

Speech Therapy

Reading and writing disorders are most often rooted in underlying language weaknesses. Because spoken language, reading, and writing rely on shared systems, difficulties in literacy are frequently best understood—and treated—through a language-based lens.

For speech-language pathologists, reading and writing disorders fall squarely within the scope of language intervention.

Definition of Reading and Writing Disorders

Reading and writing disorders occur when a child demonstrates persistent difficulty with one or more of the following areas:

• Decoding and word recognition
• Reading comprehension
• Spelling and written mechanics
• Written expression and organization

These difficulties are language-based and commonly involve deficits across the same five domains affected in spoken language disorders:

• Phonology
• Morphology
• Syntax
• Semantics
• Pragmatics

In practice, reading and writing disorders are not separate from language disorders—they are another way language weaknesses manifest as academic demands increase.

This is the SAME as language disorders. 

Language Foundations of Reading and Writing Disorders

Semantics and Syntax

Vocabulary knowledge and grammatical skills form the foundation for reading comprehension and written expression.

Reading comprehension refers to understanding what is read—not decoding. To comprehend text and express ideas in writing, students must:

• Understand word meanings
• Recognize relationships between words
• Interpret sentence structure
• Use grammar to convey meaning

Delays in receptive or expressive language significantly increase risk for later reading and writing difficulties. This is why language-based intervention targeting vocabulary and grammar is essential for students with literacy challenges.

Phonology, Phonological Awareness, and Decoding

Speech sound development and phonological processing are critical for learning to read.

To decode effectively, a student must:

• Have accurate internal representations of speech sounds
• Be able to produce and discriminate those sounds
• Understand that words can be broken into smaller sound units

Phonological awareness—the ability to manipulate sounds within words (e.g., syllable segmentation, rhyming, sound deletion)—is a key predictor of reading success and a frequent area of need for students with reading and writing disorders.

Narrative Structure & Reading Comprehension

Ah, my favorite section. I love working on narrative structure because it can make such a huge impact academically and socially. According to, Adlof, S. M., McLeod, A., & Leftwich, B. (2014). Structured narrative retell instruction for young children from low socioeconomic backgrounds: A preliminary study of feasibility. Frontiers in Psychology. https://doi.org/10.3389/fpsyg.2014.00391, narrative instruction has the ability to target vocabulary, grammar, reading, and obviously narrative language skills. 

Narrative structure plays a central role in both reading comprehension and written expression.

Narrative structure (also referred to as story grammar or story schema) reflects the predictable organization of stories, including:

• Characters
• Setting
• Problem
• Events
• Resolution

Students with strong narrative skills actively organize information as they read, which supports:

• Comprehension
• Recall
• Identifying main ideas and details
• Retelling and summarizing
• Written composition

Weaknesses in narrative structure often result in poor comprehension, fragmented retells, and disorganized writing.

Reading and Writing Disorders: The Role of Speech Therapy

Speech-language pathologists support students with reading and writing disorders by targeting the language systems that underpin literacy, rather than isolated academic tasks.

Intervention may include:

• Vocabulary depth and word learning strategies
• Grammar and sentence structure
• Phonological and morphological awareness
• Narrative organization and discourse skills
• Oral rehearsal to support written expression

These approaches support both spoken and written language outcomes.

Supporting Students Beyond the Therapy Session

Progress is strongest when language skills are reinforced consistently across contexts. Short, meaningful practice opportunities embedded into classroom routines and daily activities often support generalization more effectively than isolated drills.
