This guide covers England. It is information, not medical advice. Dyslexia varies a lot from person to person, so treat this as a starting point, not a substitute for a proper assessment.
What dyslexia actually is
Dyslexia is a common learning difficulty that mainly causes problems with reading, writing and spelling. It is a specific learning difficulty, which means it affects particular skills used for learning rather than learning as a whole. The single most important thing to understand is this: dyslexia does not affect general intelligence. A child can be dyslexic and highly able at the same time. The NHS estimates that up to one in every ten people in the UK has some degree of dyslexia.
It often shows up as a mismatch. A child understands ideas well when they hear them, but struggles to get them down on paper, reads slowly or inaccurately, muddles similar words, or finds spelling exhausting. Because that mismatch is confusing, dyslexic children are sometimes wrongly seen as not trying, which can knock their confidence hard.
Support in school is based on a child's needs, not on a formal label. Your child does not need a confirmed diagnosis of dyslexia before the school can start helping.
So if reading and writing are a struggle, that is reason enough to talk to the school now, whether or not a formal assessment has happened.
How dyslexia is assessed
This part surprises many parents. The NHS does not usually assess for dyslexia, because it is treated as a learning difficulty rather than a medical condition. So a GP is not normally the route to a dyslexia assessment.
Instead, the SENCO at your child's school may carry out screening or use checklists to understand your child's strengths and difficulties and work out how to support them. A fuller, formal assessment is usually done by a specialist assessor or an educational psychologist. Schools can sometimes arrange this, and some families choose to pay for a private assessment, though a formal report is not needed to start SEN support.
What support a school can put in place
Once the difficulty is recognised, there is a lot a school can do through SEN support. Depending on your child, that might include:
- Targeted teaching of reading and spelling, often in a smaller group
- Extra time and clearer, step-by-step instructions
- Assistive technology, such as text-to-speech or a laptop for longer writing
- Coloured overlays or particular fonts and layouts, where they help
- Marking that recognises ideas and effort, not only spelling
- In some cases, access arrangements in exams, such as extra time, which the school can advise on
Schools also have duties under equality law to make reasonable adjustments for disabled pupils, and dyslexia can count as a disability. The aim is simple: to remove the barriers, so the child's ability can actually show.
Gather what you are seeing
Before you talk to the school, it helps to bring together what you have noticed. Concrete examples land far better than a general worry.
- Examples of reading or writing that show the difficulty, with dates
- The mismatch between what your child can say and what they can write
- School reports and any comments from teachers
- Anything that already seems to help at home
If the difficulties are more complex
Most dyslexia is supported well through SEN support. If your child's needs are greater than that can meet, perhaps alongside other difficulties, you can ask your local authority to carry out an EHC needs assessment. You do not need a diagnosis to make that request, and if the authority refuses, you can appeal to the SEND Tribunal.
Parents often spend years sensing that something does not add up before anyone names it. Meanwhile the school understands the process and the terminology, and you are trying to learn it while also supporting a child whose confidence may be taking a battering.
AI can help with the information-heavy parts: understanding the language, getting your observations into a clear form, and preparing for the conversations. It does not assess your child, and it is not a substitute for a specialist assessor, an educational psychologist or the SENCO.
What AI could help with
- Explain terms like specific learning difficulty, screening and access arrangements
- Turn your examples into a clear summary of how reading and writing affect your child
- Draft the questions to ask the SENCO or a private assessor
- Summarise a long assessment report into plain English
- Help you write a calm request for an EHC needs assessment, if you need one
Do not use AI to diagnose dyslexia, and do not treat an online quiz or an AI answer as an assessment. A proper assessment needs a qualified specialist. AI can also invent statistics, techniques and sources while sounding confident. Use it to understand and organise your own information, and rely on qualified people and official guidance for anything that decides support.
A better way to prompt it
That keeps AI where it is genuinely useful, helping you prepare and explain, while the assessment and the teaching stay with the people qualified to do them.
Where to get proper help
- Your child's SENCO, as a first conversation
- The British Dyslexia Association, for information and assessment routes
- Your local SEND Information, Advice and Support Service (SENDIASS)
- IPSEA (Independent Provider of Special Education Advice), for free advice on support and plans
- EHCP Expert, if your child may need an EHC plan

Common questions
Is dyslexia a sign of low intelligence?
No. Dyslexia is a specific learning difficulty that mainly affects reading, writing and spelling. It does not affect a person's general intelligence.
Does the NHS diagnose dyslexia?
The NHS does not usually assess for dyslexia, because it is treated as a learning difficulty rather than a medical condition. Assessment is usually arranged through the school or by a specialist assessor or educational psychologist.
Can my child get help without a formal diagnosis?
Yes. Support in school is based on need. The SENCO can put SEN support in place, and may use screening or checklists, without a formal diagnosis first.
What support can a school give?
SEN support such as targeted teaching and reasonable adjustments, and in some cases access arrangements in exams. If needs are more complex, you can ask for an EHC needs assessment.
