Dyslexia Diagnostic Assessment

A full diagnostic assessment will help you gain a better understanding of the learning differences that may be contributing to slower than expected progress at school.

A  full  Diagnostic Dyslexia Assessment takes about 4 hours in total to complete.

Benefits of a Full Diagnostic Assessment include:

  • Comprehensive written report detailing all areas of strength and identifying any areas of weakness
  • Comprehensive recommendations for how to support both at home and learning institution
  • Peace of mind that your child, young adult or yourself, will now be able to get the type of support they need

How it works

Diagnostic assessments are carried out at the ‘Icanavan’  classroom at LynebyLyne Headquarters in Suffolk.

In School/Learning Institution with their permission.

In special circumstances, in your own home.

A blended approach to assessment is available, with an element being carried out remotely via Zoom and an element being carried out face to face.

 In order to establish the learning differences and any problems or difficulties, the first step is to complete the background information questionnaire.

A link to the appropriate questionnaire will be shared via Microsoft forms or if you prefer a paper copy please click on the appropriate age to download the background questionnaire:

Pre 16:   Primary Assessment Pack

Pre 16:  Secondary Assessment Pack

Post 16: Secondary Assessment Pack

Adult (18+): Adult Assessment Pack

It is beneficial if the school/Learning Institution also complete a questionnaire as this will give a far clearer picture of the learner. A Microsoft form link  will be sent via email, once the deposit has been paid.


Once this has been received a Diagnostic  Assessment session can be booked.

A pre-assessment Zoom meeting will help build rapport and alleviate anxiety, as well as address any questions.

The assessment may be over two session, one remotely and one face to face.

Both sessions will involve standardised tests and assessments and take approximately 3-4 hours in total to complete.

 After analysis of the results, a full DAR (Diagnostic Assessment Report) is written, including recommended support for home and school.

This can take a minimum  of 4 weeks to complete.
