How do you test for dyslexia?

You can screen for the possible presence of dyslexia, or you can undertake a formal assessment process.


Screening is the first stage in identifying whether a person may have dyslexia. It looks for possible indicators and estimates whether an individual is ‘at risk’ of having dyslexia.

It can provide useful insight into general areas of difficulty and can include a recommendation as to whether a formal diagnostic assessment is required.


A definitive diagnosis of dyslexia for any individual requires a full diagnostic assessment to be carried out by a competent and suitably qualified professional. The assessment itself will explore a range of skills and cognitive processing capabilities.

The resultant report will provide details on the nature and severity of any difficulties identified, as well as making recommendations as to how to best support the individual moving forward.
