Dyslexia or Specific Learning Disability: how to tell

When letters seem to dance on the page and reading feels like hard work, the right understanding turns frustration into a clear, hopeful path forward.

In short

Dyslexia is one specific type of Specific Learning Disability (SLD) — the part that affects reading, spelling and decoding words. SLD is the broader umbrella that also includes difficulties with writing (dysgraphia) and maths (dyscalculia). You cannot know for certain at home — these are identified through a structured educational and clinical assessment, usually meaningful from around age 6–8 years, once formal reading instruction is well underway. What you can do is notice the patterns and seek a proper evaluation.

Signs worth noticing

In a child who is otherwise bright, curious and developing well in other areas, watch for a persistent gap between effort and reading progress:

• Reading — slow, hesitant or effortful reading; guessing words from the first letter; losing their place; avoiding reading aloud.
• Spelling & writing — spelling the same word different ways; reversing letters or sounds beyond the early years; writing that is far behind their spoken ideas.
• Sounds & words — trouble breaking words into sounds, rhyming, or linking letters to sounds.
• Pattern — the difficulty is specific (often reading) rather than across all learning, and persists despite good teaching and effort.

Dyslexia is not a sign of low intelligence, laziness or poor effort — children with dyslexia are often highly capable thinkers who simply process written language differently.

Dyslexia or the wider SLD?

Think of it simply: if your child mainly struggles with reading and spelling, that points towards dyslexia. If difficulties also clearly involve written expression or maths, the picture may be a broader Specific Learning Disability. Only a structured assessment — looking at reading, spelling, writing, maths, attention and overall ability together — can tell which pattern fits your child, and that distinction shapes the support they receive.

When to seek a check

A formal assessment becomes meaningful from around 6–8 years, once a child has had real exposure to reading instruction. Seek a check if the gap between your child's ability and their reading is widening, if they are losing confidence or avoiding school work, or if a teacher raises concerns. Earlier than this, watch and support playful language and sound games rather than worry about a label.

The Pinnacle way

A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre, under qualified clinician care — never from an app, online quiz or this page. Our team builds a precise learning and developmental profile that distinguishes dyslexia from the broader Specific Learning Disability, then shapes targeted support through special education and learning support and, where helpful, speech and language therapy for the underlying sound-processing skills.
