Specific Learning Disability (ICD-11 developmental learning disorder, 6A04) is grouped by the affected skill — reading (dyslexia), written expression (dysgraphia) and mathematics (dyscalculia) — and described by severity as mild, moderate or severe rather than fixed levels. A child may have one type or several together, usually recognised around ages 6–8.

*"Is it just dyslexia, or are there different kinds?" — it's one of the first things parents ask, and the answer brings real clarity.*

## In short
Specific Learning Disability isn't a single thing — it describes a group of brain-based differences in how a child learns specific academic skills, despite ordinary teaching and good effort. The WHO's ICD-11 groups these as **developmental learning disorder (6A04)** with three main types: difficulty with **reading** (often called dyslexia), with **written expression** (dysgraphia), and with **mathematics** (dyscalculia). Rather than "levels", these are described by **severity** — mild, moderate or severe — based on how much support a child needs to keep pace. A child can have one type or more than one together.

## The three types, simply
- **Reading (dyslexia):** trouble with accurate or fluent word reading, decoding sounds, or understanding what's read — even when the child is bright and trying hard.
- **Written expression (dysgraphia):** difficulty with spelling, grammar, punctuation, or organising ideas clearly on the page; handwriting may be effortful too.
- **Mathematics (dyscalculia):** difficulty with number sense, learning maths facts, or accurate, fluent calculation and reasoning.

Instead of fixed "levels", clinicians describe each as **mild, moderate or severe** — a practical way of saying how much extra teaching or accommodation a child needs. Importantly, SLD is identified only when difficulties are well below what's expected for the child's age, persist over time, and aren't better explained by vision or hearing issues, lack of schooling, or another condition. This is why it's usually recognised around **ages 6–8**, once formal academic learning is well underway.

## The Pinnacle way
AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from an article or an app. Our team looks at the whole picture of how your child reads, writes, calculates and learns, then builds a plan around their strengths. Explore [Specific Learning Disability support](/specific-learning-disability), our [special education and learning support](/special-education), and [how the AbilityScore® works](/ask/what-is-the-abilityscore-and-how-is-it-calculated).

## Trusted sources
WHO ICD-11 classifies developmental learning disorder (6A04) by the affected skill — reading, written expression and mathematics. The CDC and the Indian Academy of Pediatrics emphasise that learning differences are best identified once formal schooling begins, with severity guiding the level of support a child needs.

This is general information, not a diagnosis — individual assessment and diagnosis require an appropriately qualified healthcare professional.
