Student Context
Specific Learning Disability
General Overview
Learning disability is a general term that describes specific kinds of learning problems. Learning disabilities can cause a person to have trouble learning and using certain skills. The skills most often affected are: reading, writing, listening, speaking, reasoning, and doing math. Learning disabilities (LD) vary from person to person. One person with LD may not have the same kind of learning problems as another person with LD.
Researchers think that learning disabilities are caused by differences in how a person’s brain works and how it processes information. Children with learning disabilities are not “dumb” or “lazy.” In fact, they usually have average or above average intelligence. Their brains just process information differently. There is no “cure” for learning disabilities. They are life-long. However, children with LD can be high achievers and can be taught ways to get around the learning disability. With the right help, children with LD can and do learn successfully.
When a child has a learning disability, he or she:
may have trouble learning the alphabet, rhyming words, or connecting letters to their sounds;
may make many mistakes when reading aloud, and repeat and pause often
may not understand what he or she reads;
may have real trouble with spelling;
may have very messy handwriting or hold a pencil awkwardly;
may struggle to express ideas in writing;
may learn language late and have a limited vocabulary;
may have trouble remembering the sounds that letters make or hearing slight differences between words;
may have trouble understanding jokes, comic strips, and sarcasm;
may have trouble following directions;
may mispronounce words or use a wrong word that sounds similar;
may have trouble organizing what he or she wants to say or not be able to think of the word he or she needs for writing or conversation;
may not follow the social rules of conversation, such as taking turns, and may stand too close to the listener;
may confuse math symbols and misread numbers;
may not be able to retell a story in order (what happened first, second, third); or
may not know where to begin a task or how to go on from there.
General Information
Definition: Learning Disabilities
The term “learning disabilities”, sometimes referred to as specific learning disabilities, is an umbrella term that covers a range of neurologically based disorders in learning and various degrees of severity of such disorders.
Broadly speaking, these disorders involve difficulty in one or more, but not uniformly in all, basic psychological processes: (1) input (auditory and visual perception), (2) integration (sequencing, abstraction, and organization), (3) memory (working, short term, and long term memory), (4) output (expressive language), and (5) motor (fine and gross motor). ()
Definition: Reading Disability
A reading disability is a condition in which a sufferer displays difficulty reading. Examples of reading disabilities include: Developmental Dyslexia, Alexia (acquired dyslexia), and Hyperlexia (word-reading ability well above normal for age and IQ). ()
Definition: Dyslexia
Dyslexia is an unexpected difficulty in reading for an individual who has the intelligence to be a much better reader. It is most commonly due to a difficulty in phonological processing (the appreciation of the individual sounds of spoken language), which affects the ability of an individual to speak, read, spell and, often, learn a second language. ()
Characteristics
Primary
Cognitive: Impaired cognitive functioning
Examples include problems with reading, spelling; processing problems including memory and thought organization; and metacognition.
Communication: Problems with the output of expression of thoughts and ideas
Examples include developmental aphasia, dysgraphia, and the interpretation of body language
Sensory: Problems with sensory-perceptual/acuity; auditory perceptional difficulties; and sensory integration
Examples include problems with seeing figure-ground, closure and spatial relationships; difficulties with sound discriminations and/or sound recognition; and oversensitivity to lights, sounds, smells, touch, or taste.
Secondary
Emotional/Social: Problems with self-regulation, stressed internal emotional state; non- verbal communication
Example: Problems with self-control and accepting responsibility for one’s actions; sabotage success and undermine self-confidence as a residual effect of an internal emotional state that has experienced failure and frustration. Inability to read gestures, nuances, facial expressions and body language lead to problems with interpersonal relationships and social issues.
Update (2025-09-24): The SLD definition at 34 CFR §300.8(c)(10) identifies affected areas (e.g., reading, written expression, math) and exclusionary factors. https://www.law.cornell.edu/cfr/text/34/300.8

Cognitive Processes
There are many cognitive processes that are critical to learning. Some are listed in the definition of learning disability in the SLD section. This section will include information on:
Input (visual, auditory, tactile)
Integration
Memory
Output (sharing what has been learned)
Motor
Executive Functioning
Input
Our brains are constantly processing a variety of sensory input. When it comes to learning and instruction, there are three areas that may have a big impact.
Visual input processing can affect how we process text, images, charts, graphs, and other visual information. Students may have problems recognizing the size, shape, and placement of text, or have problems with line and paragraph typography.
Auditory processing can affect phonemic awareness, distinguishing subtle differences in sounds. Students may have problems distinguishing figure and background sounds. They may struggle to hear and focus on what the teacher is saying if there are other sounds that distract them. They may also have difficulties associating sounds with symbols.
Tactile processing can provide additional information that can help students understand some types of information. Our brains do an amazing job of combining various types of input to create a unified awareness, which is one reason math manipulative can help students understand mathematics concepts. It is also a reason multi-sensory instruction can be highly effective.
Strategies
Use transformative tools, such as text-to-speech, to scaffolding difficulty in decoding text.
Highlight, or visually mark up, text to support visual navigation of content.
Use visual reading guides (physical and digital) to support consistent visual movement through a text while reading.
Simplify digital and online text by removing distractions on the page.
Use text summarizers to reduce the amount of content in a text so students can learn the core ideas, then add the rest of the content.
Ensure that the reading level is appropriate when working on word recognition.
Use text-to-speech to provide access to appropriate content when the language comprehension is higher than the word recognition skills.
Change the size and type of font used.
Adjust the spacing between letters, words, sentences, and paragraphs.
Reduce the width of the columns of text.
Use personal or classroom audio FM systems.
Use manipulatives to enhance math and science instruction.
Use models and 3D printing to support understanding of difficult and abstract concepts.
Integration
Students are often juggling information, trying to understand what they are learning while also trying to make connections with additional knowledge or background knowledge. Understanding concepts often means understanding relationships between bits or chunks of knowledge. This can be as basic as sequencing events in an order, such as a time line, or it may require putting abstract concepts together to infer meaning, see a bigger picture.
Many students struggle with integrating information. Sometimes visualizing the process by putting it on paper can help. Our brains tend to "think" in patterns and using visual representations of how bits of information relate to each other gives students a way to externalize their thinking. Consider these images:
Each graphic represents a different way of connecting information and we tend to recognize the differences. One shows a hierarchy, one shows a process or progression, and one shows how information can overlap with parts being different and parts being similar or shared. This is an example of externalizing how we think, and once these tools are on paper or a computer screen students can use these tools to help internally integrate ideas, concepts, and information.
Strategies
Build background knowledge to increase opportunities for making connections and anchoring new knowledge.
Use topic-focused wide reading to increase students' knowledge base and background knowledge.
Use contrast/comparisons and analogies to widen understanding.
Use graphic organizers, concept maps, mind maps, timelines, outlines, etc. to organize information and visually integrate different bits of information or events with each other.
Use diagrams and draw math problems.
Draw pictures of word problems.
Use graph paper.
Use infographics, posters, and other visual tools to help highlight main ideas and important concepts.
Highlight, or visually mark up, text and math problems to support visual organization of content.
Provide or use advance organizers to get a big picture of the organization of the text before reading the main content.
Consistently use text markup strategies to support a thoughtful processing of the text. Provide students a variety of highlighting and text markup strategies that support basic to advanced integration skills.
Consistently use mental models, such as K-W-L, Compare-Contrast, etc.
There are several different types of models that people use to try to understand what memory is and how it works. For our purposes we will take a simplistic approach. Generally, a memory can be viewed as a network of parts of the brain that "fire" or are activated at the same time. This network is sometimes referred to as an engram. Working memory refers to the ability to take in information and use it while taking in more information. It is being able to work with information coming in (the input processing) and at the same time using that information (the integration processing) in order to solve problems, complete assignments, etc.
The stronger the engrams, or chemical networks/memories, are the easier it is for students to remember information and put it in working memory. So the more parts of the brain that are activated in an engram, the stronger the memory. Have you ever smelled something and suddenly remembered something in your past? What do you think of when you see the word "cinnamon." Do you think of a taste, a food, a spice, a color? Do you remember a place, an event? The more mentally complex a memory the easier it is to recall. So adding pictures to vocabulary words can help with memory. Having students draw pictures to go with concepts, and explain verbally how their pictures represent the concepts can also improve recall because they have the concept, imagery, analysis thinking, and verbalization all working together to help remember that concept. Using multi-sensory instruction strategies can help students grasp instructional goals by creating complex cognitive networks.
Strategies
Use multi-sensory instructional strategies.
Provide advance organizers and guides to highlight main ideas and concepts, and have the students refer back to these guides often while reading the content.
Processing, or reading through, the content several times, each time with a different focus (e.g. making personal connections with the text, asking questions, analyzing the structure, reading for understanding, reviewing). Remember to always increase the complexity to align with the goals of the standards.
Use visual graphic organizers or timelines to help organize the information.
Have the students create illustrations for parts of the information and explain the thinking behind the illustrations.
Comparing and contrasting different ideas, events, concepts, etc.
Maintaining a journal and reviewing the journal on a regular basis.
Using flash card type tools to review facts and events.
Use screen capture tools on interactive whiteboards to save work and then review that work the next day.
Use a spiral curriculum sequence where you continually address and revisit the grade level standards for a course throughout the year.
Provide each student a book of sets of instructions, formulas, rubrics, guidelines, etc. that they can use all year as a reference tool.
We are constantly asking students to demonstrate what they have learned. It's how we judge if they have responded to the instruction. But some students can have problems sharing what they know, especially on demand.
There are two basic types of communication language situations, spontaneous language and demand language. Many students are fine with spontaneous language because they are communicating what their brain is processing at that time. But those students may have real problems communicating what they know on demand because their brain needs time to recall the information (memory) and then to organize what they have recalled (integration) in a way that can be verbalized or written. Sometimes they may share something completely off topic because that is what their brain has processed so that is what they have to say.
You can use the tools and strategies from the integration and memory sections to help students prepare for on demand language situations. If the student has been using visual tools such as graphic organizers to visually process what they have been learning and has been keeping those tools and reviewing them on a regular basis to help remember what they have learned, then those same tools now become prompts to help share what they have learned verbally, in writing, or in other media.
Strategies
Use discussion guides, graphic organizers, or outlines ahead of time that support the organization of main ideas to share, then use them as prompts when sharing with others. An example of this is used in the classroom video on the Inclusion page.
Prepare fact cue cards prior to sharing.
Prepare vocabulary cue cards or lists prior to sharing.
Review text mark-ups and notes on facts, questions, and reactions to the text prior to sharing.
Use presentation guides, such as PowerPoint slides or teleprompters, to support sharing.
Provide options on how students can share what they know, such as writing, drawing, audio, role-playing, etc.
Motor skills, in conjunction with eye-hand coordination and visual spatial organization abilities, are often critical skills needed for engagement in instructional activities. Some students struggle with handwriting. They may have problems holding and controlling a writing tool such as a pencil or pen. Poor spatial planning skills can result in frustration when trying to complete a writing, math, or drawing assignment. Even something as "simple" as drawing a room in their house can be extremely frustrating.
Some students may have problems using manipulatives due to weak fine motor strength and muscle coordination. This can result in problems in any class that uses manipulatives, such as math, or science and biology labs. it can also affect social skill development, as some students may be seen as being clumsy and may have problems participating in some group activities and project based learning.
Strategies
Use pencil grips and writing tools.
Use paper lined with writing guides.
Use raised line paper for tactile response with writing.
Use graph paper to help with spatial placement and writing math problems.
Use word processors for writing.
Use word prediction and grammar checkers to support writing assignments.
Allow the student to use tape recorders for lectures, or smart pens that record audio and align the audio to writing and drawing.
Allow dictation and speech-to-text tools.
Try 3D software for students who have problems with spatial planning on paper.
Executive Functioning
Planning, organization, goal setting, strategizing, remembering details, managing time all of these are a part of executive functioning. Problems here can impact many areas of learning such as task persistence, self-direction, and completing assignments.

Memory
ldaamerica.org
/types-of-learning-disabilities/memory
Affects storing and later
retrieving information or
getting information out.
Three types of memory are
important to learning, “working
memory”, “short term memory” and
“long term memory.” All three types
of memory are used in the
processing of both verbal and non
verbal information.
“Working memory”
refers to
the ability to hold on to pieces of information until the pieces blend into a full thought or
concept. For example, reading each word until the end of a sentence or paragraph and
then understanding the full content.
“Short-term memory”
is the active process of storing and retaining information for a
limited period of time. The information is temporarily available but not yet stored for
long-term retention.
“Long-term memory”
refers to information that has been stored and that is available
over a long period of time. Individuals might have difficulty with auditory memory or
visual memory.
How does it all work together to learn?
One reads a sentence and holds on to it. Then the next and the next. By the end of the
paragraph, he pulls together the meaning of the full paragraph. This is working memory. He
continues to read the full chapter and study it. Information is retained long enough to take a
test and do well. This is short-term memory. But, unless the information is reviewed and
studied over a longer period of time, it is not retained. With more effort over time, the
information might become part of a general body of knowledge. It is long-term memory. If
there are deficits in any or all of these types of memory, the ability to store and retrieve
information required to carry out tasks can be impaired.
Auditory Processing Disorder — Strategies

similar-sounding words (celery/salary; belt/built; three/free; jab/job; bash/batch)
May be confused by figurative language (metaphor, similes) or misunderstand puns and
jokes; interprets words too literally
Often is distracted by background sounds/noises
Finds it difficult to stay focused on or remember a verbal presentation or lecture
May misinterpret or have difficulty remembering oral directions; difficulty following
directions in a series
Has difficulty comprehending complex sentence structure or rapid speech
“Ignores” people, especially if engrossed
Says “What?” a lot, even when has heard much of what was said

Documentation & Compliance
This section references the federal definition of SLD and the required criteria and documentation for eligibility decisions under IDEA Subpart D (34 CFR §§300.307–300.311). See Updates above for links.
Issues & Troubleshooting
Prolonged RTI tiers without timely evaluation when a disability is suspected.
Supports that reduce task rigor instead of providing access to grade-level standards.
Over-reliance on a single identification method (e.g., only discrepancy or only RTI data).
Assistive tools selected by brand rather than needed features; poor training or follow-through.
