# What are the types or levels of Dyslexia?

Dyslexia is described less by fixed "levels" and more by pattern and severity. Common patterns include phonological (sound-processing), surface (whole-word recognition), rapid-naming (fluency) and mixed difficulties; severity is described as mild, moderate or severe by how much support is needed. It is usually identified once formal reading instruction is underway, around ages 6–8.

*If reading feels like an uphill climb for your child, understanding what kind of difficulty they face is the first step to helping them.*

## In short
Dyslexia isn't a single thing with neat "levels" — it's better understood by the *pattern* of reading difficulty a child shows. Clinicians usually describe it by **severity** (mild, moderate or severe, based on how much support is needed) and by the **underlying difficulty** — most commonly trouble linking sounds to letters (phonological), trouble reading smoothly and quickly (fluency or naming-speed), or a mix of both. Dyslexia is a recognised specific learning difficulty in reading under WHO's ICD-11, and it is best confirmed through assessment once formal reading instruction is well underway, usually around ages 6–8.

## The patterns clinicians describe
**By how it shows up in reading:**
- **Phonological dyslexia** — the most common pattern: difficulty breaking words into sounds and blending sounds back into words (sounding out *c-a-t*).
- **Surface (or visual) pattern** — difficulty recognising whole familiar words at a glance, so reading stays slow and effortful even for common words.
- **Rapid-naming difficulty** — slow at quickly naming letters, colours or objects, which affects reading speed and fluency.
- **Mixed pattern ("double deficit")** — both sound-processing *and* naming-speed difficulties together, often needing the most support.

**By severity:** clinicians describe dyslexia as **mild, moderate or severe**, judged by how much it affects everyday reading and how much structured support a child needs to progress. These are descriptions, not fixed boxes — a child's profile can shift with the right teaching.

## When to seek a check
Reading develops at different rates in the early years, so dyslexia is usually identified once a child has had consistent reading instruction — generally from around **6–8 years**. Worth a developmental check if your child reliably struggles to learn letter sounds, reads far below their age peers, avoids reading, or has a family history of reading difficulty. Earlier signs like trouble with rhyming or learning the alphabet are worth watching, but they aren't a diagnosis on their own.

## The Pinnacle way
A clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed **only at a Pinnacle Blooms Network centre, under qualified clinician care** — never from an online list or an app. With 4.95 lakh+ families served and structured, evidence-based support, our team can map exactly where your child's reading profile sits today and what will help most.

## Trusted sources

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