How to Get Tested for Dyslexia in the UK: A Practical Guide
If you suspect you or your child has dyslexia, getting a proper assessment is an important first step. A formal diagnosis can unlock support at school or work, explain why reading and writing feel more difficult, and open doors to helpful tools and strategies. But the process of how to get tested for dyslexia UK can feel confusing, with different pathways depending on your age and circumstances.
This guide walks you through the main routes to assessment, what happens during testing, and what to expect afterwards.
Start with Your GP
Your General Practitioner is usually the best starting point. Book an appointment and explain that you or your child is struggling with reading, writing, or spelling, and you'd like to explore whether dyslexia might be involved.
Bring specific examples: difficulty with phonics, trouble spelling common words, reading more slowly than expected, or problems with organisation and memory. GPs can refer you to educational psychology services or specialist dyslexia clinics through the NHS. Be aware that NHS waiting lists can be lengthy, sometimes 6 to 12 months depending on your area.
If your GP is reluctant to refer, ask politely to have your request recorded in writing. You can also ask to be referred to a different healthcare professional if you feel you're not being listened to.
The School Route: For Children
If your child is at school, talk to the class teacher or Special Educational Needs Coordinator (SENCo) first. Teachers see reading and writing difficulties daily and can spot signs that warrant further investigation.
The SENCo can arrange initial screening through the school and may recommend an educational psychologist assessment. If your child's difficulties significantly affect their learning, the school may initiate an Education, Health and Care Plan (EHCP) needs assessment, which includes comprehensive dyslexia testing.
Keep records of any concerns you raise with the school in writing, via email. This creates an important paper trail and ensures your worries are documented.
Private Assessment: The Faster Route
If you want a quicker assessment, private dyslexia testing is available across the UK. Educational psychologists in private practice can carry out thorough assessments, typically within 2 to 6 weeks.
Expect to pay between £500 and £1,500 for a comprehensive assessment, depending on your region and the evaluator's experience. Some private practitioners offer discounts if you're referred by a school or if you're testing multiple children.
When choosing a private assessor, check they're registered with the British Psychological Society (BPS) and have specific experience with dyslexia. A private diagnosis is recognised by schools, universities, and employers, and it provides the same legitimacy as an NHS diagnosis.
What Happens During the Assessment
Dyslexia testing is thorough and multi-faceted. You can expect:
Cognitive testing: Tasks that measure processing speed, working memory, phonological awareness, and visual-spatial skills. These aren't "IQ tests" in the traditional sense, but they reveal how your brain processes information.
Reading and spelling tests: The assessor will ask you to read passages aloud, answer questions about what you've read, and spell words. They're observing not just accuracy but how you approach the task.
Phonological awareness tasks: Rhyming words, blending sounds, or identifying syllables. Dyslexic readers often struggle here because dyslexia fundamentally affects how the brain processes sounds and language patterns.
A detailed history: You'll discuss your early literacy development, family history of dyslexia, and how reading and writing affect your daily life. Context matters; there's no single test that "proves" dyslexia.
The whole assessment usually takes 2 to 4 hours, sometimes split across two sessions. It's thorough because dyslexia affects everyone differently, and a good assessment captures the full picture.
Supporting Your Child Before and After Testing
While waiting for assessment, there's plenty you can do to help. At home, create a supportive environment where reading doesn't feel like a failure. Read to your child, listen to audiobooks together, and celebrate effort over accuracy.
If your child is already struggling with reading, tools like Dyslexly can make a real difference. The free Chrome extension offers OpenDyslexic font, which many dyslexic readers find clearer and easier to decode. It also includes text-to-speech, colour overlays, and line focus features that reduce cognitive load while reading online.
At school, ask the teacher about any existing support your child receives and request it continue during and after assessment. Reasonable adjustments, such as extra time on tests or using a reader, shouldn't depend on a formal diagnosis, though a diagnosis strengthens your case.
After You Have a Diagnosis
Once you have a formal assessment report, the real work of getting support begins. In school settings, share the report with the SENCo and ask about an EHCP assessment or a smaller support plan. Your child may qualify for exam access arrangements at GCSE and A Level, such as extra time or the use of a reader.
At university, students with dyslexia can access Disabled Students' Allowance (DSA), which funds specialist equipment and support. The university's disability support service will need a copy of your assessment report.
In employment, you're entitled to workplace adjustments under the Equality Act 2010. You don't have to disclose dyslexia to your employer, but if you do, they must make reasonable adjustments. Tools like text-to-speech and speech-to-text software, flexible deadlines, or roles that play to your strengths (rather than demanding intensive written work) are common examples.
Many adults find that understanding their dyslexia, rather than the diagnosis itself, is the turning point. You've finally got an explanation for struggles you've faced for years.
Costs and Funding
NHS assessments are free but involve waiting times. Private assessments cost £500 to £1,500. Some people split the difference: they ask their GP for an NHS referral and, if the wait is long, fund a private assessment themselves. You can then use the private report to speed up school support while on the NHS waiting list.
Check whether your employer offers occupational health assessments that might include dyslexia screening. Some insurance policies or employee assistance programmes cover this. Schools cannot legally charge families for EHCP assessments, though they're sometimes funded from stretched budgets.
Conclusion
Getting tested for dyslexia in the UK requires patience and persistence, but it's worthwhile. Whether you choose the NHS route, school-based assessment, or private testing, a formal diagnosis opens access to real support and removes the shame or self-doubt that often accompanies undiagnosed dyslexia. Start with your GP or your child's school, gather examples of the difficulties you're experiencing, and don't hesitate to advocate for yourself. Once you understand how your brain works, you can seek tools, strategies, and environments that genuinely help.
Frequently Asked Questions
How long does it take to get a dyslexia assessment on the NHS? NHS waiting times vary widely by region, typically ranging from 6 to 12 months. Some areas have shorter waits; others are considerably longer. Contact your local NHS service directly for a realistic timeframe in your area.
Can my GP refuse to refer me for dyslexia testing? Your GP cannot legally refuse a request in writing, though they may ask for clarification or suggest alternatives first. If you feel your concerns aren't being taken seriously, ask for the referral to be recorded in your medical notes and consider seeking a second opinion from another GP.
Is a private dyslexia diagnosis accepted by schools and universities? Yes, private assessments carried out by registered psychologists are recognised by schools, universities, and employers. Ensure your assessor is registered with the British Psychological Society for maximum credibility.
What if my child is too young to be assessed for dyslexia? Formal dyslexia assessment is usually reliable from age 7 onwards, once basic literacy instruction has been in place. Younger children may be screened for risk factors, but a definitive diagnosis typically comes later. Early support and observation are still valuable, even without a formal label.
Can adults get tested for dyslexia if they were never diagnosed as children? Absolutely. Many adults are diagnosed later in life. Educational psychologists routinely assess adults, and the process is the same. A diagnosis can explain lifelong struggles and unlock support at work or in further education.
