Adult Assessments

If you are not in full time education, then you will need to pay to have a test for dyslexia. Some large employers and those in the public sector would be expected to fully fund a diagnostic assessment. Smaller employers agree to fully or partly funding a diagnostic assessment (although there is no legal obligation for them to do so).

There are 4 different types of assessment:

Dyslexia Checklist

A free checklist which covers some of the main areas that people with dyslexia may have difficulties in. The checklist does not provide proof that you have dyslexia (or the severity), but does provide an indication of whether a professional assessment would be helpful.

Online Screening Test:

An online screening test which can help people to identify their strengths and weaknesses, and whether it is likely that they have dyslexia. The report can be used by employers to identify areas which could require reasonable adjustments to be made in the workplace. Some employers will not accept an online screening test as proof of dyslexia.

This type of assessment is suitable for you if you are an adult and do not think that you will be returning to education.
