If you suspect you might have dyslexia, undergoing a dyslexia assessment can help you to get the clarity you need. Not sure what to expect? Find out what a dyslexia assessment normally entails, who’s eligible for one, and what support is available for dyslexia in the workplace.
A dyslexia assessment is pretty much what it says on the tin: an assessment for dyslexia carried out by a professional. Dyslexia assessments are normally conducted by psychologists, psychiatrists, or other qualified assessors. They’re there to oversee the assessment and determine whether a person meets the diagnostic criteria for the condition. During a dyslexia assessment, the specialist may also explore options for support in the classroom or workplace.
Although 10% of people in the UK are dyslexic, dyslexia assessments aren’t available on the NHS; therefore, they do need to be paid for.
Dyslexia assessments can be helpful for:
When it comes to testing for dyslexia, there’s no upper age limit. Many adults pursue assessment in their 30s, 40s, or beyond.
If you’re planning to go for a dyslexia test, it can be helpful to know what to expect. Dyslexia assessments can last up to 4 hours and normally include a thorough review of a person’s educational background, specific challenges with reading or writing, and discussions around any previous assessments.
There’s normally a diagnostic interview; this is a relaxed conversation that covers a person’s history and strengths and weaknesses. Then, there’s a selection of tests that look at things like phonological processing (how someone processes speech), reading and spelling, processing speed, and writing samples.
These tests aren’t there to catch you out. They’re designed to be accessible and non‑invasive, and will give the assessor a good indication of where you struggle and might need support.
In terms of feedback, some assessment providers offer verbal feedback on the day, while others provide this once the report is complete.
Prices for dyslexia assessments can vary but tend to start at around £400 in the UK. Some people may be eligible for subsidised or funded assessments through local authorities, universities, or employer schemes such as Access to Work.
When hunting for an assessor, it’s important to find someone credible and qualified. If you’re booking a test in the UK, look for assessors with the following credentials:
Only assessors with a current APC or HCPC registration can produce reports accepted for Disabled Students’ Allowance (DSA) or Access to Work.
You’re well within your rights to ask questions before booking. A good assessor will explain their approach and what you can expect.
Although you’ll probably receive some verbal feedback on the day, following an assessment, it can take up to six weeks to get a detailed diagnostic report. This is normally around 15–25 pages and covers:
Once you have a diagnostic report, it can be used as evidence in schools, universities, or workplaces across the UK. This can help you to apply for special accommodations or DSA.
Both a dyslexia assessment and a workplace needs assessment are recommended for adults with dyslexia, but they aren’t the same thing. Unlike a dyslexia assessment, which focuses primarily on diagnosing dyslexia, a workplace needs assessment looks at any adjustments or tools you might need to carry out your job effectively.
A workplace needs assessment can’t be used to diagnose dyslexia. Most employers require a diagnostic report before funding support, and Access to Work typically uses that report as the starting point.
If you need support at work, speak to your employer. Dyslexia can be formally recognised as a disability under the Equality Act 2010 if it has a substantial impact on a person’s daily tasks; however, this doesn’t necessarily need to be proved for someone to benefit from workplace adjustments. If you’re struggling with organisation, reading, spelling, or written communication, you should let your line manager know so that they can support you (even if you’ve not yet had an assessment).
You may benefit from simple adjustments like:
Your employer may also be able to help you with funding for a dyslexia screening or a workplace needs assessment.
Yes, if it meets certain criteria. Dyslexia is, first and foremost, a learning difficulty, but it can be recognised as a disability under the Equality Act 2010 when it significantly affects daily activities.
Nope. If you’re an adult with dyslexia, it’s recommended to book directly with a qualified assessor.
No. Although online screening tests can help to highlight risk, they can’t give you a formal diagnosis.
Most dyslexia assessors provide reports within 4 weeks, but you may hear back sooner depending on the complexity of your assessment/whether there’s a backlog.
Absolutely. Many adults with dyslexia find relief after seeking an assessment later in life, as it allows them to understand long‑standing challenges and access workplace support.
