Formal diagnostic assessments for adults and children can be expensive, though schools, colleges and universities (and some employers) do provide them if needed.
These pages should help you start the process of seeing if you or your child, have any dyslexic traits and may be in need of a full assessment. Note that adults and children have different assessments.
Dig-iT hopes in the near future to compile a list of local accredited professionals whom you can contact.
In the meantime, please follow the links to further information and guidance about assessments, which you may find useful.
