Understanding a Full Diagnostic Dyslexia Assessment
A full diagnostic assessment provides a comprehensive evaluation of your child’s strengths and difficulties. In the UK, these assessments are carried out in line with professional standards set by SASC (SpLD Assessment Standards Committee).
It offers clarity, reassurance, and practical recommendations to support your child both at home and in school, helping to take the guesswork out of how best to support them.
Not sure if your child needs a full assessment?
A screening can be a helpful first step to guide that decision.
What is a Full Diagnostic Assessment?
A full diagnostic assessment is a detailed evaluation that builds a complete picture of how a child learns — not just what they can or can’t do, but why. It is most commonly used to identify specific learning difficulties such as dyslexia and to guide the right support.

After the Assessment
-
After the assessment, you will receive a clear, easy-to-understand written report within 15 working days. It outlines your child’s strengths and areas of difficulty, explains how they learn, and, where appropriate,identifies specific learning difficulties such as dyslexia.
-
The report includes practical, tailored recommendations to support your child at home and in school, along with guidance on classroom support.
-
Overall, it provides clear next steps and helps take the guesswork out of how best to support your child.
The report is a formal, professional document based on standardised assessment.
It can be used as evidence for exam access arrangements (EAA), where there has been prior agreement with the school and in line with JCQ regulations.
It may also support applications for Disabled Students’ Allowance (DSA), where appropriate.
