DyslexiA Assessment & TEST

What is a Dyslexia Diagnostic Assessment or test?

A formal diagnostic dyslexia assessment or test provides confirmation about whether an individual has dyslexia or not. It provides a detailed picture of a person’s areas of strengths and weaknesses and an understanding of their cognitive profile.


Once the dyslexia assessment has been made, a written report is provided. This provides details of a person’s dyslexic profile (if they are identified with dyslexia) with recommendations of how to support them in their learning and everyday life.

It may also suggest other organisations to contact and/or make recommendations for further assessments for other specific learning difficulties, if this is something that has been highlighted by the dyslexia assessment.

What is the Process for a Diagnostic Dyslexia Assessment?

There are 3 stages in the process for a diagnostic dyslexia assessment.

  1. Background information is collected in a questionnaire

Although dyslexia affects literacy skills, there are other characteristics that need to be investigated in order to provide a bigger picture of a child’s strengths and weaknesses

Information is collected in a questionnaire about birth history, family history of dyslexia, child development, educational history, general health, vision, hearing, speech and language development, coordination, attention and self-esteem, communication and relationships.

This can be completed by the parent themselves or with the assessor, either in a one to one situation or via Zoom or Skype. This also provides an opportunity for a parent to ask any questions that they may have.

  1. Diagnostic Assessment 

The diagnostic assessment takes 3 to 4 hours. For younger children, it is often carried out over 2 sessions. There are a wide range of tests involving listening, looking, reading, writing and spelling.

Most children enjoy the experience and all tests have a cut-off point so that a child is not expected to continue beyond a level of difficulty that is comfortable for them.

  1. Feedback Meeting to Parent

Once the report is written, a one-hour feedback meeting is arranged with the parent. The report is given to the parent at the meeting and the results of the assessment discussed in detail. This provides an opportunity for the parent to ask any questions that they may have.
