My Child Is Good at Spelling – Could They Still Be Dyslexic?

Your child spells well.

Perhaps they usually score highly in weekly spelling tests. Maybe their teacher has specifically said that their spelling is too good for them to be dyslexic. Yet something still does not quite fit.

Reading may be slow. Written work may take much longer than expected. They may struggle to get their ideas onto paper, forget what they have just read or become exhausted by tasks that seem relatively straightforward for other children. So can a child really be dyslexic if they can spell?

The short answer

Dyslexia is not identified because somebody cannot spell. Equally, it cannot be ruled out because somebody can. A diagnostic assessment looks for a pattern across different areas of literacy and the processes involved in learning. Spelling is one useful piece of that picture, but it is only one piece.

Why do we associate dyslexia with poor spelling?

Persistent spelling difficulty is common in dyslexia. English spelling requires us to connect speech sounds with written letters and patterns, then retrieve those patterns efficiently when writing. For some dyslexic learners, that process is particularly difficult.

However, dyslexia does not produce exactly the same profile in every person. One child may have significant spelling difficulties. Another may spell reasonably well but read very slowly. Another may have developed strong spelling strategies while continuing to experience difficulty with reading fluency, processing or written expression. This is why looking for one defining sign can be misleading.

But my child gets 10 out of 10 in their spelling test

This is useful information, but it is worth looking at how the spelling has been learnt. Some children become extremely good at preparing for spelling tests. They may repeatedly practise the ten words they know will appear on Friday. They may use visual memory, rules, mnemonics or considerable repetition.

The important question is whether that learning transfers. A parent might notice that their child:

• •learns a spelling successfully for Friday but cannot remember it two weeks later
• •spells a word correctly in a test but differently in independent writing
• •asks how to spell familiar words despite previously learning them
• •relies heavily on spellcheck or avoids more ambitious vocabulary
• •takes a long time checking written work
• •recognises that a word looks wrong but cannot work out how to correct it

Equally, some children really are strong spellers. That still does not tell us how efficiently they read or process written language.

Dyslexia is a profile, not a spelling test

A diagnostic assessment does not ask only whether a child is bad at spelling. It considers a broader profile. Depending on the individual assessment, this can include word reading, reading fluency, reading comprehension, spelling, writing, phonological processing, phonological memory, rapid retrieval, working memory and processing speed. Findings are considered alongside developmental and educational history.

It is the pattern that matters. A child can perform strongly in one area and still show significant difficulties elsewhere. Our guide to what a specialist assessor notices beyond a screener explains how those apparently uneven results are interpreted.

What else should I look for?

If spelling appears secure, think about reading and writing more generally. Does your child read accurately but considerably more slowly than expected? Need to reread? Understand much more when information is read to them? Become tired after sustained reading? Avoid reading aloud? Struggle with unfamiliar or longer words? Have excellent ideas verbally but produce much less in writing? Take far longer than expected to complete written work? Find timed work much harder than untimed work?

None of these signs proves dyslexia. A persistent pattern can justify looking more closely. For detail on the difference between accurate and easy reading, see why reading can leave a child exhausted.

What if school says their spelling is too good for dyslexia?

It is reasonable for school to consider spelling as part of the evidence. However, spelling alone cannot establish whether dyslexia is present or absent. A useful conversation moves from ‘Is their spelling okay?’ towards ‘How easily and efficiently are they managing literacy as a whole?’

Ask about reading fluency, reading stamina, written output and how long tasks take. Sometimes attainment looks acceptable while the effort required to achieve it is much less visible. The free child dyslexia indicator check can help you organise what you are noticing before speaking to school.

Could something else explain the difficulties?

Yes. Slow or effortful literacy can have several explanations. Attention, language development, educational experience, anxiety and other factors may affect performance. Assessment should not begin with an assumption that every difficulty is dyslexia. Its purpose is to understand the profile.

When might an assessment be useful?

It may be worth exploring further when difficulties are persistent, affect day-to-day learning or seem inconsistent with your child's wider abilities. Assessment can be useful when everyone agrees a child is capable, but nobody can quite explain why aspects of learning require so much effort. Read more about dyslexia assessments for children.

A good speller can still be dyslexic

There is no single dyslexia score and no single dyslexia symptom. Poor spelling can be part of a dyslexic profile. Good spelling does not rule one out. If you would like to talk through the pattern you are seeing, a free 15-minute call is available without obligation.
