**In short:** A disorder affecting one or more basic learning processes, such as reading (dyslexia), writing (dysgraphia), or math (dyscalculia).
**Specific Learning Disability (SLD)** is the most common IDEA disability category, affecting how the brain processes information in specific areas. SLDs include difficulties with reading (dyslexia), written expression (dysgraphia), and mathematics (dyscalculia), despite adequate intelligence and instruction.

## Identification

Schools may identify SLD through discrepancy models (comparing achievement to ability) or Response to Intervention (RTI) approaches examining how students respond to increasingly intensive instruction. Comprehensive evaluations assess cognitive processing, achievement, and educational impact.

## Instructional Approaches

Effective SLD instruction is explicit, systematic, and multisensory. It addresses underlying processing weaknesses while teaching compensatory strategies. Students may need accommodations like extended time, audiobooks, or assistive technology.

## Frequently asked questions

**Q: What is a specific learning disability?**

An SLD affects how the brain processes information in specific areas like reading, writing, or math, despite normal intelligence. Examples include dyslexia and dyscalculia.
**Q: How is SLD different from intellectual disability?**

Students with SLD have average or above intelligence with specific processing difficulties. Intellectual disability involves below-average cognitive functioning across areas.
