Specific Learning Disorder: Understanding Difficulties in Reading, Writing, and Math

A child can be intelligent, curious, motivated, and still have a significant learning disorder.

Specific Learning Disorder, or SLD, is a neurodevelopmental disorder affecting the acquisition and use of academic skills.

It can involve reading, written expression, mathematics, or more than one academic area.

Specific Learning Disorder is not simply “doing poorly in school”

Children can struggle academically for many reasons: inconsistent instruction, absences, attention difficulties, anxiety, language barriers, medical issues, or changes in school environment.

Specific Learning Disorder is different.

The academic difficulties are persistent and significantly greater than expected, even when the child has had appropriate opportunities to learn.

The diagnostic process therefore looks at the child’s academic performance in the context of development, instruction, history, and other abilities.

Specific Learning Disorder with impairment in reading

Reading difficulties can involve accurate word recognition, decoding unfamiliar words, reading fluency, or reading comprehension.

The term dyslexia is commonly used to describe a learning disorder primarily affecting word-level reading and spelling.

A child may read very slowly, guess at unfamiliar words, struggle to connect letters with sounds, or require much more effort than classmates to read the same material.

Specific Learning Disorder with impairment in written expression

Difficulties may involve spelling, grammar, punctuation, organizing ideas, or producing clear written language.

It is important to distinguish this from handwriting difficulty alone.

The term dysgraphia is used in different ways and may describe handwriting or graphomotor problems in some settings. A formal evaluation helps determine whether the primary difficulty involves motor output, written language, spelling, or a combination.

Specific Learning Disorder with impairment in mathematics

A mathematics disorder may involve difficulty understanding numbers and quantities, learning math facts, performing calculations accurately or fluently, or applying mathematical reasoning.

The term dyscalculia is commonly used for significant mathematics learning difficulties.

Does a child need a low IQ to have a learning disorder?

No.

A child with a learning disorder may have average, above-average, or even very high intellectual abilities.

In fact, one reason learning disorders can be confusing is that a child’s academic performance may appear inconsistent with how capable they seem in conversation, reasoning, creativity, or other areas.

A comprehensive evaluation therefore looks beyond one score or one classroom grade.

How is Specific Learning Disorder diagnosed?

There is no single dyslexia, dyscalculia, or learning-disability test.

Assessment typically examines academic achievement, developmental and educational history, response to instruction, language, cognition, attention, and other factors that may affect academic performance.

The goal is not simply to determine that a child is struggling.

The goal is to determine why.

A diagnosis can then identify the specific academic area affected and the nature of the child’s learning profile.
