Assessments vs. Screening
The only way that dyslexia can be formally identified is by a Diagnostic Assessment carried out by a qualified assessor. Screening tests can be a really useful tool as long as they are carried out with the understanding that they can only give an indication of possible dyslexic difficulties, and that they are not 100% accurate.
There are many different types of screening tests; some have to be carried out by a trained SENCo whereas others can be taken online. We would always advise that if a screening test indicates that there is a moderate to high probability of dyslexic difficulties that this is followed up with a Diagnostic Assessment. This assessment will determine the precise nature of the difficulties, and how they can best be supported.
