Getting a Diagnostic Assessment

Diagnostic Assessments can be carried out by a qualified Educational Psychologists or a Specialist Assessor.

The following organisations and individuals provide assessments for a range of SpLDs (Specific Learning Difficulties such as Dyslexia, Dyspraxia, Dyscalculia, ADHD) for children and adults.

We are not recommending any of these in particular. We suggest you look at websites and contact those whichever you feel would suit your (or your child’s) needs.
