Many dyslexic people have strengths such as unusual problem solving, pattern recognition, creative talents, thinking outside the box, determination and empathy. However, they may also have challenges with working memory and the ability to distinguish between very similar sounds. In addition, they may have experienced an education system which is not tailored to their needs, and so may be left with a legacy of weaker reading or spelling.

 Getting an Assessment

However, there are many good coping strategies and lots of technology solutions have been developed. The route to finding good coping solutions, usually starts with a diagnosis of strengths and challenges.

Diagnostic Assessments 

A diagnostic assessment is the only way to really understand if someone is dyslexic and where their particular strengths and weaknesses lie. The BDA can provide a full range of diagnostic assessments. We use a variety of assessment measures and professional assessors who are highly qualified, assessed for competence and required to undertake mandatory CPD.

The below document provides guidance on what qualifications and experience a dyslexia assessor should have:

Guidance : What to Look for in a Dyslexia Assessor

The cost of an assessment is £450 (+ VAT) with a specialist teacher and £600 (+ VAT) with an Educational Psychologist. Assessments are conducted by Specialist Teacher/Assessors with current Assessing Practising Certificate (APC) or Psychologists registered with the Health and Care Professional Council (HCPC).

The assessment will normally take around 2.5 to 3 hours and the report will be sent through to you within 15 working days.

Please note: we will try and arrange an assessment within three weeks of receiving the booking form, however there is more availability in some parts of the UK than others. We will always try and accommodate urgent appointments. We will try to find you an assessor local to you, however sometimes it may be necessary to travel.

Checklists and Screening Tests

These are short tests designed to flag up the probability of dyslexic difficulties. They are not a diagnosis and do not analyse the nature of an individual's dyslexic profile, which can vary considerably between people with dyslexia both in the nature of the particular difficulties and in their severity. A good starting point is to complete our Adult Checklist

A screening test would indicate the probability of dyslexia as low, medium or high. No screening test is 100% reliable in its prediction and there may be a few false positives or false negatives. For instance, well compensated people with less severe dyslexia may not be flagged up in a screening test. We also have a range of excellent adult screening tests linked to our website which produce a report that you can save or print off. Where a checklist or screening test shows the probability of dyslexic difficulties, a full diagnostic assessment may be considered in order to inform the process of determining the most appropriate reasonable adjustments.

Full Diagnostic Assessments

Dyslexia can be diagnosed by Chartered Psychologists specialising in adult dyslexia who may also be able to identify frequently co-occurring conditions such as Dyspraxia, Dyscalculia and Attention Deficit Disorder. These professionals are usually Educational or Occupational Psychologists. Occasionally Clinical Psychologists specialise in this area. Occupational Therapists often play an important part in assessment of Dyspraxia. 

You should also check that they have current HCPC registration. Assessments can also be carried out by an appropriately qualified specialist dyslexia teacher with a post graduate Diploma in Specific Learning Difficulties and an Assessment Practising Certificate. They are able to make assessments of verbal and non-verbal intelligence but use different tests from those only available to Psychologists. Full assessments for adults would take around 3 hours and would be followed by a detailed written report with broad recommendations for support and accommodations.

Education and University

For Further Education, there may be the possibility of an assessment organised by the Learning Support Department of a College.

For Higher Education, a few universities may fund or part-fund assessments, but this is not normally offered. We advise you to contact the Disability Advisor at the University for further advice. Students aiming to attend university should ensure that they have an assessment report post 16 years from either an HCPC registered Psychologist or a Specialist Dyslexia Teacher with a current Practice Certificate for assessing students at H.E.


Employees who may be experiencing performance issues or stress at work which may be a result of previously undiagnosed dyslexic difficulties should discuss the matter in confidence with HR/Occupational Heath/their Manager. Employers have a duty under the Equality Act 2010 to ensure that employees with disabilities (including dyslexia) are not treated unfavourably and are offered reasonable adjustments or support. For many office based jobs, a full understanding of the individual profile is necessary in order to offer the most effective support. Most large employers and the public sector would be expected to fund an assessment for an employee. A smaller employer may help with the cost.

Following the diagnostic assessment, or where an employee is able to show an existing adult assessment report, a workplace needs assessment should then be arranged with a dyslexia specialist in order to determine the most appropriate accommodations, training and support that would be successful in mitigating any weak areas and reduce stress. This is not something that either the individual or the employer would be able to work out for themselves.
